Chevrolet Suburban

1972–1978 Chevrolet Veraneio

In 1964, Chevrolet in Brazil introduced a 5-door version of the Suburban called C-1416 (known as Veraneio from 1969 onwards, which is Portuguese for "summertime"). It was based on the contemporary Brazilian Chevrolet C-14. Like the C-14, the C-1416/Veraneio used the instrument cluster from the US C/K series although the exterior sheet metal layout is exclusive to Brazil. It was initially powered with a Chevrolet 4.2 L inline-six based on the pre-1962 "Stovebolt" engines. Later it used the 250 cu in (4.1 L) engine from Chevrolet's Brazilian mid-size sedan – the Opala. The original version of the Veraneio was kept in production, with another grille and interior, until 1988 (model year 1989), but it was eventually replaced with an updated version based on the Série 20 family.[35] The second generation of Veraneio was produced from 1989 to 1995.

In 1997, GM introduced the then-current North American pickups to the Brazilian market, replacing the long running C-series. The Brazilian version of the Suburban was also converted to the current generation at the time and lasted until 2001 as the "Grand Blazer", succeeding the Veraneio. The 4.1-liter inline-six engine with 138 hp (101 kW) was offered on both models with option for a MWM 4.2 L turbodiesel unit with 168 hp (124 kW).

In 2015, Autoweek ranked the Veraneio fourth among Chevrolet station wagons never sold in the US. It also cited the vehicle's design as "baroque" and summed it up as "a 1960s Brazilian crossover." Autoweek noted that the Veraneio is eligible for import to the United States under the 25-year exemption.[36]

The Suburban shared several engines with the C/K pickup truck line. A 250 cubic-inch inline six was the standard engine through 1979. The model line was offered with a 307 (1973 only) and 350 cubic-inch small-block V8s; a 454 cubic-inch big-block V8 was optional in C-series Suburbans. For 1976, the 350 V8 was joined by 305 and 400 cubic-inch V8s; the latter was discontinued in 1980. For 1980, V8 engines became standard for the model line, with the 305 returning as the standard engine for 1981. For 1982, GM introduced a 6.2L Detroit Diesel V8 as an higher-efficiency alternative to the 7.4L V8.[52]

A 3-speed manual transmission was offered through the 1980 model year, with a 4-speed manual offered through 1987. Initially offered with 3-speed Turbo Hydra-Matic 350 and 400 automatic transmissions, a 4-speed Turbo Hydra-Matic 700R4 became an option in 1981.

For 1980, K-series Suburbans moved from full-time four-wheel drive to a part-time system, allowing the front axle to freewheel.[53] For 1981, shift-on-the fly 4x4 drive adopted automatic-locking front hubs; the NP208 transfer case replaced the NP205 in most examples.[54][55]

For 1987, GM redesignated the Rounded-Line C/K series as the R/V series to accommodate the launch of the 1988 GMT400-platform C/K trucks, which were being launched in the spring of 1987. For 1987, the gasoline engines of the model converted from carbureted fuel delivery to electronic fuel injection (using throttle body injection/TBI). For 1988, the 5.0L engine was dropped from the line, with the 5.7L V8 becoming the standard engine. In a trim revision, the R/V line adopted the nomenclature of its GMT400 successor, with all vehicles adopting the 1500/2500/3500 payload series (previously used by GMC) and the base Custom Deluxe trim retired and replaced by a revived Cheyenne trim.

For 1989, the exterior underwent its largest revision since its 1973 introduction. Adopting a style similar to the GMT400, the black-painted grille was offered with quad headlights (economy trims were equipped with two). After using the same design nearly unchanged since 1973, the steering wheel was replaced (adopting the same design as the GMT400).[53]

For 1990, the Suburban introduced power-operated sideview mirrors, also adding the option of rear-wheel ABS. Alongside the Suburban and Blazer/Jimmy, the R/V line was pared down nearly exclusively to 1-ton crew-cab pickup and chassis-cab trucks.

For 1991, the 4-speed 700R4 automatic transmission was replaced by the electronically-controlled 4L80E unit. After an 18-year production run, the Rounded-Line Suburban ended production as GM shifted crew-cab pickup truck and full-size SUVs to the GMT400 platform for 1992.

In Australia and New Zealand, Holden imported the right-hand drive Chevrolet Suburban built by GM in Silao, Mexico, between February 1998 and January 2001.[59] The Suburban was first previewed in October 1997 at the Sydney Motor Show.[60] In total, 746 were sold (460 petrol and 286 diesel).[61] After 2001, subsequent models reverted to the original Chevrolet brand, which had also been used before 1998. Over the model's lifetime there were three trim levels: a base model, the LS and the LT. Not to be confused with the trim variants is the model code, designated K8.[62]

Holden Suburban (K8) 1500, New Zealand model

The Holden's interior differed from that of the American version, as the right-hand drive dashboard of the Blazer was used instead. However, it had to be stretched on the passenger (left) side to fit in the larger Suburban. A bench seat came standard on the entry-level variant as well as the LS, but the more expensive LT received bucket seats. With the omission of the center seat, the LT has a maximum seating capacity of eight, compared to nine.[63]

Creature comforts standard in all models included a LCD compass in the rear-view mirror, a tilt adjustable steering wheel, a driver's airbag, ABS brakes, and dual-zone air conditioning.[63] The second tier LS brought alloy wheels, power windows and mirrors among some features. To further up the ante, the LT gained electric front seats, leather trim, and a horizontally slated, two-part tailgate. This came as opposed to the "barn doors" found on the other specifications.[64]

The Suburban was offered with the choice of either a 5.7-liter Vortec V8, producing 190 kW (255 hp; 258 PS) and 447 N⋅m (330 lb⋅ft; 46 kg⋅m) of torque, or a 6.5-liter turbodiesel V8 outputting 145 kW (194 hp; 197 PS) and 583 N⋅m (430 lb⋅ft; 59 kg⋅m).[63] The former choice was designated the "1500" name, while the turbodiesel saw the "2500" identify.[64] The 5.7-liter petrol engine is LPG-compatible, and such systems can be retrofitted if desired. Regardless of the engine specified, the truck was equipped with a four-speed automatic transmission. However, what differed was the type of transmission. Petrol motors were fitted with the GM 4L60-E transmission, with the GM 4L80-E reserved for the diesel.[61] A dashboard switch allows the vehicle to power all four wheels simultaneously, or the rear wheels only, and allows the low range gearing to be engaged.[63]

The vehicle's fuel efficiency has been rated at 19.7 L/100 km (14.3 mpg_‑imp; 11.9 mpg_‑US) for the diesel specification,[65] with that figure rising to 21.8 L/100 km (13.0 mpg_‑imp; 10.8 mpg_‑US) for the petrol model.[66] With the hefty fuel consumption comes a 159-litre (35 imp gal; 42 US gal) fuel tank.[63]

To combat the extra payload and towing capacity of the diesel, an improved braking package, as well as super heavy duty axles and suspension were fitted. Holden recommends a maximum 3,400 kilograms (7,500 lb) towing limit for the turbo diesels, with a reduced figure of 2,720 kilograms (6,000 lb) for the petrol models.[63]

The Holden Suburban's run wasn't the first or only time that Holden had sold the GMT400 platform in Oceania. Beginning in 1996, they imported GMC C/Ks for ambulance conversions. Unlike the Suburbans, these vehicles were not available to the general public, nor did they bear Holden badging. They also were not built as right-hand-drives from the factory like the Suburban was; the same company that handled the ambulance conversion (Jakab Ambulance in Tamworth) also switched the steering to the other side.

• Vortec 6000 364 cu in (5,960 cc) V8 (335 hp (250 kW; 340 PS) at 5200 rpm and 375 lb⋅ft (508 N⋅m; 52 kg⋅m) of torque at 4000 rpm).
• Vortec 8100 496 cu in (8,130 cc) V8 (325 hp at 4200 rpm and 447 lb⋅ft (606 N⋅m; 62 kg⋅m) of torque at 3200 rpm).
• Vortec 5700 350 cu in (5,700 cc) V8 remained in use in 2002-00 Suburbans, Tahoes (called Sonora) as well as Silverado pickup trucks in the Mexican market

The newly redesigned Suburban and Yukon XL were showcased to the public for the first time on September 27, 2013, at the State Fair of Texas.[96][97] This move comes on the heels of the 80th anniversary of the first production of the Suburban in 1934.

The designs and concepts were created by GM's exterior design manager Chip Thole (before his transfer to GM's Buick design studio in 2013), who told Truck Trend "I start with what intuition tells me about the market and get the team going on that. You look at trends around the industry – fashion, culture, what people are buying, what they say they want now – and project that into the future. The fun part is putting those ideas to paper and going from there." He then added, "We wanted to take what was good about today's vehicles, bring that forward and make them new and different with that spark of freshness that people recognize, without making them gimmicky or overdone." Thole also challenged his design team to help bring ideas to the SUVs, which lead to the split headlamps and a more graphic feel for the Suburban design, while a more industrial but sculptured look was added to the Yukon XL to give it a unique identity of its own.[98]

Production on the Suburban and Tahoe began in December 2013 with the first completed SUVs being used for testing purposes.[99] GM then officially started shipping the vehicles to dealerships on February 5, 2014.[100] It is estimated that it takes 8–10 weeks to assemble the SUVs, save for the upgrades on the level trims and destination scheduling.[101]

The front fascias of the Chevy Suburban and GMC Yukon XL are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, improving aerodynamics, fuel economy, and lessens interior noise. The hoods and liftgate panels are made of aluminum to reduce vehicle weight, and the wiper blades that were located on the liftgate door were moved to the rear spoiler located on the top of the rear liftgate window. Also noticeable is the SUV's length, which expands from 222.4 to 224.4 in (5,649 to 5,700 mm) (the Yukon XL's length is shorter at 224.3 in (5,697 mm)) and its width from 79.1 to 80.5 in (2,009 to 2,045 mm), while the height decreases from 76.8 to 74.4 in (1,951 to 1,890 mm), thus allowing the vehicle to become slightly leaner, a little bit wider, more streamlined, and roomier.

A more efficient, direct-injected EcoTec3 V8 powertrain (5.3 for the Suburban, 6.2 for Yukon XL/Yukon Denali XL) coupled with improved aerodynamics, helped the SUVs offer greater estimated highway fuel economy and improving its fuel economy estimates to 16 mpg_‑US (15 L/100 km; 19 mpg_‑imp) (city), 23 mpg_‑US (10 L/100 km; 28 mpg_‑imp) (highway), and 18 mpg_‑US (13 L/100 km; 22 mpg_‑imp) (combined) for 2WD, and 15 mpg_‑US (16 L/100 km; 18 mpg_‑imp) (city), 22 mpg_‑US (11 L/100 km; 26 mpg_‑imp) (highway), and 18 mpg_‑US (13 L/100 km; 22 mpg_‑imp) (combined) for 4WD.[102] The increased fuel economy also vaulted the Suburban/Yukon XL into the top spot among large SUVs with the most efficient fuel economy rating numbers for this segment.[103] However, when Motor Trend (which placed the 2015 Suburban on the front cover of its June 2014 issue) did a road test review on the SUVs, it estimated the 4WD MPG on the Suburban LTZ to be slightly better at around 15.2 mpg_‑US (15.5 L/100 km; 18.3 mpg_‑imp) city and 22.3 mpg_‑US (10.5 L/100 km; 26.8 mpg_‑imp) highway, while the 4WD Yukon Denali XL, whose fuel economy (MPG) is rated at 14 mpg_‑US (17 L/100 km; 17 mpg_‑imp) city and 20 mpg_‑US (12 L/100 km; 24 mpg_‑imp) highway, was estimated lower at 12.4 mpg_‑US (19.0 L/100 km; 14.9 mpg_‑imp) city and 19.2 mpg_‑US (12.3 L/100 km; 23.1 mpg_‑imp) highway.[104]

Like the 2007–14 version, both the Suburban and Yukon XL do not share a single piece of sheet metal or lighting element with the brands' full-size pick-up trucks (GMC Sierra and Chevy Silverado), and the front grilles of both vehicles are slightly altered to give it their own identity. The front headlights feature projector-beam headlamps that flank the Chevrolet-signature dual-port grille – chrome on all models, sweeping into the front fenders, while the Tahoe, Suburban LTZ, Yukon, and Yukon XL Denali trims feature projector-beam high-intensity discharge headlamps and light-emitting diode daytime running lamps. The Yukon and Yukon XL also feature projector-beam halogen headlamps on all SLE and SLT trims. The improved safety features included a 360-degree radar detection for crash avoidance and occupant protection and a high-tech anti-theft system that now includes vertical and interior sensors, in-glass and window breaking, a triggering alarm, and a shutdown device that prevents the vehicle from moving. The latter is expected to address the issues regarding the constant thefts of the vehicles, especially with the previous generation's removable seats and items left in the cargo space, which has become a target for carjackers who see the third-row seats as valuable on the black market.[105] According to General Motors' head of Global Vehicle Security Bill Biondo, "We have engineered a layered approach to vehicle security," adding that "With new standard features and the available theft protection package, we are making the vehicles less attractive target to thieves and more secure for our customers."[106]

Also new are the addition of fold-flat second and third-row seats (replacing the aforementioned removable third seats), which is now a standard feature but can be equipped with an optional power-folding feature for the upgraded trims, and an additional two inches of legroom for second-row passengers. HD radio became a standard feature on all trims. Multiple USB ports and power outlets are now spread throughout their interiors, including one 120 V three-prong outlet on both Suburban and Yukon XL, with the Suburban adding an available eight-inch color touch screen radio with next-generation MyLink connectivity along with an available rear-seat entertainment system with dual screens and Blu-ray DVD player, while the Yukon XL adds a standard eight-inch-diagonal color touch screen radio with enhanced IntelliLink and available navigation. A 4G LTE WiFi access system, along with Siri Eyes Free and text messaging alerts, was included in all vehicles that feature the OnStar device around the second quarter of 2014.[107][108]

With the change to the K2 platform, GM discontinued the 3⁄4-ton Suburban 2500; however, plans were revealed to offer a K2-based Suburban HD for fleet sales according to an updated VIN decoding document filed in March 2015.[109] This version, identified as a Class 3 vehicle (around 10,000 to 14,000 pounds (4,500 to 6,400 kg) GVWR), was only available as a 4WD vehicle with the same design as the eleventh generation (K2XX), but was equipped with a different engine altogether.[109] The Suburban HD was offered only in LS and LT trims, reserving the LTZ trim for a more luxurious offering (like limousine or taxi-related services).[110] It also was not offered with 2WD or upgraded packages. In addition, there were no plans to offer a 3⁄4-ton GMC Yukon XL as GM made the design exclusive to Chevrolet.[109][111]

The Suburban HD was officially named the "Suburban 3500HD", indicating a one-ton truck rating, and was introduced for the 2016 model year. This was available exclusively for fleet sales and equipped with the L96 6.0L V-8 engine, 6L90 6-speed heavy duty automatic transmission (RPO MYD), 17-inch machined aluminum wheels (8 lug), a high capacity air cleaner, 220 amp alternator, external engine oil cooler, and auxiliary transmission cooler. The 3500HD does not include HD radio.[112] Although the vehicle has a high GVWR of 11,000 lb (5,000 kg), it is intended to provide a larger payload but minimal towing capacity, as it primarily was intended for conversion to an armored vehicle.[113]

The 2020 model year would be the last year for the K2-based Suburban HD;[113] chassis production ceased in August 2018.[114][115]

The Suburban added a hands-free power liftgate feature that is standard on the LTZ but included on the LT with the optional Luxury Package. The added 4G LTE WiFi and Siri features became standard on both LT and LTZ trims, while the MyLink with Navigation feature was upgraded from optional to standard on the LTZ trim. The E85 capability feature is removed from retail orders.[116]

The Yukon XL's 6.2-liter EcoTec3 V8 engine was updated with the new 8L90E eight-speed automatic transmission for the interim model year, allowing it to improve fuel economy.[117] The Yukon XL Denali, however, saw its MSRP bumped up by $1,300 (~$1,470 in 2021) in part due to the loaded features.[118]

All GM Full-sized SUVs received a body-colored painted Shark Fin antenna as part of the 2015 mid-year refresh.

This refresh is often referred to as the 2015i, "i" for interim processing code.

For the 2016 model year (which commenced sales in July 2015), the Chevrolet Suburban received more upgraded changes and new features that included power-adjustable pedals, forward collision alert, IntelliBeam headlamps, lane keep assist, and a safety alert seat as part of the newly introduced enhanced driver alert package as an available option on the LS trim. The inside floor console with storage area-SD card reader was removed, while a new AM/FM audio integrated system with Sirius XM, HD Radio, and CD/MP3 capabilities was introduced as a standard feature on all trims; the 8-inch MyLink feature was expanded to the LS trim and became standard (replacing the 4-inch display), although the navigation feature remains as an option on LT and standard on LTZ. A new liftgate shield was added to the Theft Protection Package, along with the new lane keep assist which replaced the lane departure warning. The capless fuel fill tanks became standard on all trims. Siren Red Tintcoat and Iridescent Pearl Tricoat became the new color trims, replacing Crystal Red Tintcoat and White Diamond Tricoat. The instrument cluster was re-configured with a new multi-color enhancement and a heads-up display was introduced as a standard only on the LTZ trim.[119][120] The 2016 models also saw a price hike as well.[121]

The 2016 GMC Yukon XL also sees similar changes, with the new enhanced driver alert package as an available option on the SLE trim, liftgate, power, hands-free now packaged on SLT trims, a free-flow feature that replaced the Premium package, a lane keep assist added to all trims, and two new premium colors (Crimson Red Tintcoat and White Frost Tricoat) replacing Crystal Red Tintcoat and White Diamond Tricoat respectively.[122][123]

Chevrolet added Apple CarPlay and Android Auto Capability features to the Suburban starting with the 2016 models. However, only one of their phone brands at any one time can be used,[124] while the Android Auto option will only be available on LT and LTZ trims featuring 8-inch screens.[125]

GM expanded newer 4G LTE features (like detecting battery failure and monitoring insurance discounts based on driver performance) to 2016 model year vehicles, including the Suburban, which GM cited as being the vehicle that is the most used among data subscribers.[126]

The 2017 model year Chevrolet Suburban received upgraded changes after it went on sale in August 2016. The level trims LS and LT are retained but the LTZ is renamed Premier, the latter serving as the equivalent to the Yukon XL Denali. The LS trims also saw the badged "LS" lettering removed. The new features include two new colors (Blue Velvet Metallic and Pepperdust Metallic), two new 22-inch wheel options (a 7-spoke Silver wheels with Chrome inserts for all trims; Ultra Bright machined aluminum wheels with Bright Silver finish for Premier trim only), black roof rack cross rails (as part of the Texas Edition Package and All-Season Package), front active aero shutters (all trims), and heated and vented seats (Premier trim only). The MyLink was updated to incorporate Teen Driver, App Shop, Rear Seat Reminder customization, and Low-Speed Forward Automatic Braking (as part of Enhanced Driver Alert Package on the LS trim, but standard on LT and Premier). The Rear Seat Entertainment System was overhauled to include a new video voiceover feature for the visually and hearing impaired, an HDMI/MHL connector, digital headphones, Digital Living Network Alliance (DLNA) technology incorporated into the Wi-Fi system, and a second USB port with the capability of charging up to a 2.1-amp at the back of the console.[127][128]

The 2017 model year Yukon XL also received similar changes, but with a few exceptions. Two new colors, Dark Blue Sapphire Metallic and Mineral Metallic were introduced, the latter exclusive to the Denali, which also added a new 22-inch ultra-bright aluminum wheels with midnight silver premium paint and a head-up display to its features. The interior backlights changed from red to blue. The heated and vented driver and front passenger seats are now standard on the SLT and Denali trims.[129][130]

The 2018 model year Suburban had a few upgrades and deletions. LED daytime running lights became standard on all trims, along with a new color, Havana Metallic and Satin Steel Metallic. The Cocoa/Mahogany interior that was combined with the Pepperdust Metallic exterior was dropped along with the wireless/inductive phone charging that was part of the Luxury and Texas Edition LT level trims. The fleet/commercial level trim, which had fewer features, is upgraded to include MyLink, HD Radio, multi-color driver information center, LED daytime running lights, and an optional driver alert package.[131]

The 2018 Yukon Denali XL received a new grille with a layered appearance like the ones on its redesigned 2018 Acadia and Terrain brands, featuring high-intensity-discharge headlights and LED daytime running lights. The refreshed design provides better airflow to the radiator, and when less cooling air is needed, shutters behind the grille close to improve aerodynamics and increase efficiency. The interior featured new ash wood trim that GMC says gives the cabin a richer appearance. A new 10-speed automatic transmission was mated to its 420-horsepower (313 kW; 426 PS), 6.2-liter V8 engine, replacing the 8-speed transmission.[132]

The 2019 Suburban will have both Havana Metallic and Tungsten Metallic deleted in favor of a new Shadow Gray Metallic exterior color, while the top-of-the-line Premier will now have the name displayed on the tailgate. The LS trim continues to make HD Radio a standard feature, but can be deleted if customers opt for the OnStar feature.[133]

The 2019 model year GMC Yukon XL adds three new exterior colors, Dark Sky Metallic, Pepperdust Metallic, and Smokey Quartz Metallic, while deleting two others, Mineral Metallic and Iridium Metallic. GMC also introduces two new package features, Graphite Edition and Graphite Performance Edition, which will be available in the SLT level trim only[134]

The 2020 Chevrolet Suburban dropped the LT Signature Package and the LS All-Season Package, along with the Pepperdust Metallic color,[135] while the 2020 GMC Yukon XL replaced its Pepperdust Metallic color with Carbon Black Metallic and made no additional changes.[136]

The 2015 Suburban was ranked third among the top affordable SUVs and fifth among affordable SUVs with 3-row seats by U.S. News & World Report,[137] and was among the finalists in Motor Trend's SUV of the year for 2015.[138] It also received a 2015 MotorWeek Drivers' Choice Award for best large SUV,[139] while Consumer Reports ranked the Suburban as the best SUV with a third row seat, topping its competitors in this category.[140]

The Chevrolet Suburban took third place behind the Tahoe and GMC Yukon in the 2016 J.D. Power Vehicle Dependability Study among full-size SUVs, based on responses from owners of the vehicles.[141]

Good Housekeeping named the 2018 Suburban the "Best New Car of Year 2018" in the Large SUV category. In its review of the vehicle from GH and its reason for the decision to award the SUV: "Whether you're bringing the whole soccer team home or moving kids into college, it's a larger-than-life workhorse that can handle your crew and all their stuff."[142]

Consumer Reports added the 2018 Suburban to their recommended list due to high owner satisfaction scores.[143]

The Suburban was given a Hollywood Walk of Fame star on December 5, 2019, one of two inanimate objects to be awarded such (Disneyland being the other), for its frequent appearances in film and television. Because city regulations prohibit placing corporate names on public sidewalks including the Walk of Fame, the star was instead placed in an area adjacent to the Walk of Fame.[11]

The eleventh generation Suburban saw an increase in sales; April 2014 brought a 109.8 percent spike, with most dealers reporting that the vehicles are being sold within 10 days after arriving on the lot, with customers opting for the fully loaded LTZ model, making it one of Chevrolet's fastest selling brands in 2014.[144] The eleventh generation Suburban is also a hot seller in the Middle East, where in August 2014 posted a 37% increase in sales, with most of the purchases coming from Saudi Arabia (65%), the United Arab Emirates (15%) and Qatar (108%).[145] By the end of September 2014, GM sold more than 4101 units of the Suburban (up 50.1%), while the Yukon XL posted 2165 units sold (up 64%), with GM boasting that 80% of the vehicles sold were its large SUVs.[146]

In Canada, sales of the Suburban reached 966 units (up 43%) in 2014, although the Yukon XL is the best seller in that country with 1,760 vehicles sold (up 50.3%) that same year.[147] Overall, they account for 70 percent of GM Canada's SUV sales for 2014.[148]

On August 17, 2015, GM confirmed plans to increase production on its large SUVs, especially on the Suburban/Yukon XL, due to lower gas prices and a higher demand for the vehicles. The move also resulted in its Arlington Assembly adding more hours and increasing its production from 48,000 SUVs to 60,000 based on the expanding hours and added Saturday overtime shifts.[149]

The 2017 MY Suburban saw its biggest sales increase in January 2017, when it posted a 72.3% gain (5,634 units), the most ever since January 2008 when it had the 2008 MY Suburban.[150]

Rear view

Based on the same GMT T1XX platform as the Silverado 1500, the Suburban distinguished itself by swapping that truck's live axle and leaf springs for an independent rear multilink suspension setup with coil springs, thus lowering the floor of the vehicle and creating more room, in both the cargo area and the second- and third-row seats.[157] The Suburban expanded its length to 225.7 inches (5,733 mm), and the wheelbase to 134.1 inches (3,406 mm) while shortening down by 15 inches (381 mm) longer due to the rear wheelbase moving back by 5 inches (127 mm), making it the largest and longest SUV in the extended length segment. It gains two cubic feet (57 L) of cargo space behind the third row and 2.2 inches (56 mm) of third-row legroom. The towing capabilities were increased with the twelfth generation models.[158]

The trims feature the primary basic LS, LT, and Premier levels, with the 4WD-exclusive Z71 and RST moving from package to premium levels, along with the newly added High Country level, the latter being the top of the line. Chevrolet rolled out the LT, Z71, Premier, and High Country levels first, with the LS and RST levels arriving in late Fall 2020.[159]

Quad exhaust tailpipes are added to the vehicle, giving it a more unique look, although this feature is only standard on Premier and High Country. This feature isn't offered on the LS, LT, Z71 and RST because of their configuration as regular base, off-road, and street-centric level trims respectively, nor on all trims with a Duramax option.[160] The RST Suburban, which had photos released in April 2020, has a unique fascia and a sportier design similar to its Cadillac Escalade ESV Sport level trim.[161] Both Premier and High Country trims have power-retractable assist steps that was optional on the Premier trim from the previous generation.[162]

Although it retained a boxy look, it added a more curvaceous design with this change and adopted the same Chevrolet design language featuring the front grille and distinct LED lighting that is also used on the Silverado, save for the black-grilled Z71 (without the bumper) and RST. The tailgate is more front and center, with the signature "Suburban" name stretched across it. A combination of sheet metal and aluminum was used to ensure a more lightweight vehicle.[163]

The dashboard and entertainment system have been fleshed out, moving away from the traditional design. Newly updated features include a 10.25-inch touch screen that is now standard on all trims, and a pair of 12.6-inch LCD rear screens that can play movies and offer content from passengers' smartphones and can play different programs on the two screens. A new push-button shifter column (P, R, N, D) is placed on the dashboard. Nine camera displays for enhanced towing capabilities and a total of 30 additional safety features have been implemented throughout the Suburban. An Air Ride Adaptive Suspension is standard on the higher trims, likewise with an 8-inch driver screen. Another new feature, a power sliding console that became available in late Summer 2020. The High Country Suburban also has a Deluxe package option with advance features that is exclusive to this trim only.[164] The 40/20/40 front seat option that was available on the LS trim is now exclusive to fleet orders with this generation using the same base trim.[165]

The Suburban also featured a Duramax diesel engine as an option (available on all trims and packages except for the Z71[166]) for the first time, and so far the only brand outside its competitors to have this option; a 3.0-liter I6 is used which produces 277 horsepower (207 kW; 281 PS) and 460 lb⋅ft (624 N⋅m; 64 kg⋅m) of torque. The 6.2-liter EcoTec engine that was reserved for the RST trim in the previous generation is exclusive to the High Country level trim. The engine choices added up to improved fuel economy numbers, albeit with an increased MPG for city and a decreased MPG for highway.[167] GM has no plans to offer this model in a 2500 or 3500 series version.

For the 2022 model year, the Suburban will see an increased availability of the 6.2-liter V-8, which continues to be standard on High Country but can now be fitted to the RST, Z71, and Premier trim levels, and expands the Magnetic Ride Control damping system to the RST. The 12.3-inch screen (with Google Assistant, Google Maps and the Google Play Store embedded) becomes standard on the higher trims except for the LS. A newly optional electronic limited-slip differential will be available on the Z71 trim and can be used in the 4WD Low setting.[168]

GMC unveiled its twelfth generation Yukon XL in Vail, Colorado on January 14, 2020, alongside its full-size sibling Yukon. Like the Suburban, the Yukon XL also featured an independent rear suspension, a 3.0-liter inline-six turbodiesel engine, and a top-shelf suspension option featuring air springs and magnetic-ride shocks, a standard 5.3-liter V-8, an optional 420-horsepower (313 kW; 426 PS) 6.2-liter V-8, and a 10-speed automatic transmission that is standard across the lineup. It also gained 4.1 inches (104 mm) in the wheelbase but only 0.9 inches (23 mm) in overall length, making it still short of the Suburban's length. The dashboard has two versions, one similar to the Suburban while a different one with a larger entertainment screen is exclusive to the Denali. The Yukon XL's design follows GMC's design language, with the front grille mimicking the Sierra but the tailgate mimicking the GMC crossover SUV lineup with the lights extended to the tailgate doors.

The lineup of level trims also expanded as well, with the SLE, SLT, and Denali now joined by the 4WD-exclusive AT4, the latter of which comes standard with the Magnetic Ride Control electronically adaptive dampers, AT4-exclusive leather-appointed seats, and stitching with a unique Jet Black interior color and Brandy accents, a heated steering wheel, heated and ventilated front seats, heated second-row outboard seats, a two-speed transfer case, 20-inch Goodyear all-terrain tires, Traction Select System with off-road mode, hill descent control, and skid plates.[169] The Denali level offers three packages for this generation, with Deluxe joining the Premium and Ultimate options, and became the only trim to offer quad exhaust tailpipes.[170]

For the 2022 model year, the Yukon XL added a few additions similar to the Suburban, among them a 12.3-inch digital gauge cluster that is now standard on all trims, with Google Assistant, Google Maps and the Google Play Store embedded. The power sliding center console is now standard on the Denali trim. Redwood Metallic is added as a new color option.[171]

In 2021, GM Defense was awarded a $36.4 M contract by the United States Department of State Diplomatic Security Service (DSS) for 10 GMT T1XX-based prototype Suburban HD vehicles, with uprated suspension and an undisclosed powertrain; deliveries were scheduled for Spring 2023.[172] The first prototype was shown to DSS leadership during a ride-and-drive event held at Summit Point Raceway on June 29, 2023.[114] The vehicle, which now is named the Heavy-Duty Sport Utility Vehicle (HD SUV), is offered in 1LT and 2LT trims with 4WD and the L87 6.2L V-8 engine and 10-speed automatic transmission standard; the 3.0L Duramax I-6 turbodiesel is an option.[173] The chassis is designated "eBOF" (Electric Body on Frame) and can accommodate a diverse set of powertrains, including battery electric and hydrogen fuel cell.[174] GM Defense expects to be awarded an indefinite delivery, indefinite quantity contract in September 2023, with serial production to commence in June 2024,[114] resulting in up to 2,000 HD SUVs being delivered over 10 years.[115]

For international regions, Chevrolet started selling the twelfth generation Suburban in Mexico in August 2020, but unlike the United States and Canada, Mexico only offered the Suburban in the LT, RST, and High Country trims; the LS, Z71, and Premier level trims and the Duramax option are not offered for that country. The American-built models will use the GM 10-speed automatic transmission with Electronic Precision Shift technology, manufactured at the GM Silao Complex in the state of Guanajuato in central Mexico.[175][176] The Philippines began selling the 2021–present Suburban (with a possibility that it would offer a Duramax engine option in the country should Chevrolet make it available) in fall 2020,[177][178] followed by the Middle East region.[179] In November 2020, GM announced that their large SUV lineup would be imported to China, marking the Suburban's maiden entry into the country, starting with the 12th generation models. However, GM later cancelled those plans in February 2021, citing the difficulty of having an import being sold alongside its Chinese-built offerings, the makeup of the facilities that would be required to assemble the full-size SUVs, and concerns that the full-size SUVs won't be able to comply with the stringent emission standards imposed by the Government of China.[180]

A right-hand-drive version of Suburban for Australia and right-hand-drive markets to be done by Holden Special Vehicles, which was announced in December 2019, is on hold, citing the low demand, capacity issues at HSV, and highly competitive large luxury SUV and towing market in Australia, although that could change due to GM's partnership with HSV to bring more American vehicles like the Suburban back down under the newly announced GMSV arrangement.[181][182][183][184]

The Yukon XL officially went on sale for the first time ever in Mexico, starting in the Fall of 2020 with the 2021 models (GMC had only offered the Yukon in that country due to GM not wanting to have the Yukon XL cannibalized in terms of sales with the Suburban, which is also that country's best selling SUV), where it is only available in the Denali trim.[185]

On September 26, 2014, Chevrolet debuted the updated Z71 Suburban at the State Fair of Texas, along with the debut of the Texas Edition Suburban, the latter due to Texas having the most units of Suburbans sold in the United States (As of August 2014, sales of the Chevrolet SUVs in Texas were up 37 percent) and to celebrate the 60th anniversary of GM's Arlington Assembly plant; production of the Z71 Suburban began in October 2014.

As with the previous Z71 Suburbans, this version continued to be offered in a 4WD LT trim only, featuring a front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards, and "Z71" identification inside and out. Fog lamps, front tow hooks, and front parking assist are also included. The 2016 Z71 package was modified again, as portions of the Z71 items added on the Texas Edition package as an optional feature by request from customers was discontinued, making it a stand-alone package. The Z71 package was upgraded to a level trim starting with the twelfth generation models.

The Texas Edition Suburban, which became part of the Texas Edition lineup along with the Tahoe and Silverado, was available in both LT and LTZ trims for the 2015 model year, featuring a maximum trailering package, twenty-inch polished aluminum wheels (on LT models), twenty-two-inch premium painted aluminum wheels (on LTZ models), and an exclusive "Texas Edition" badge.[186] For the 2016 model year, Chevrolet discontinued the LTZ package but modified for the LT package without the requested Z71 features. The Twelfth generation Suburban will continue to offer the Texas Edition for the LT and Premier trims only when combined with the Luxury, LT Signature, and Premium packages.

The Suburban LT Signature Edition, introduced in the 2018 model year, was an optional package trim, similar to the luxury package but with less expensive features, available in the LT level trim only. This option was discontinued after the 2019 model year but will be offered for the 2021 model year.

A Midnight Edition Suburban, an all-black optional package available in 4WD LT and Z71 versions, was introduced for the 2017 model year. This version became part of the Signature Edition Suburban feature for the 2018 model year up until the 2020 model year.[187]

On August 13, 2018, Chevrolet introduced a more upgraded version of the top-of-the-line Premier level trim of the Suburban, packaged as the Premier Plus, featuring a 6.2-liter engine, the classic gold bowtie emblems, chrome nameplate badging, and new polished 22-inch wheels. The interior is unique to these models, boasting with heated/ventilated Black-and-Mahogany leather front seats, Jet Black trim surround, a head-up display, and an eight-inch cluster. The exterior features standard cross rails, chrome power steps, and chrome exhaust tips. This feature was discontinued in the 2020 model year.[188]

Chevrolet added a new package to the 2018 model year Suburban with the introduction of the street-themed RST (Rally Sport Truck) Special Edition Suburban. Originally at the time of the announcement, it was supposed to be available as an option for the LT and Premier trims as a Performance Package that included a 420-horsepower (313 kW; 426 PS), 6.2-liter V-8 engine, a Magnetic Ride Control with performance calibration, and an all-new Hydra-Matic 10L80 10-speed automatic transmission. The press release also detailed additional features; The chrome elements are absent as body-color grilles surround the door and handles, along with an added gloss-black grille and mirror caps, black roof rails, window trim, badging and Chevy bowties, an exclusive 22-inch wheels wrapped in Bridgestone P285/45R 22 tires, a Borla performance exhaust system, massive front red Brembo six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 mm × 32 mm (16.1 in × 1.3 in) Duralife rotors, coupled with an 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity.[189]

However, after the press release Chevrolet confirmed that the RST Suburban would only be available as an appearance package, as the 6.2-liter engine would not be used for the 2018 model year.[190] But on May 4, 2018, Chevrolet expanded the RST package to the Suburban as an option for the 2019 model year that will now include the 10-speed automatic transmission and 6.2L engine, reversing a decision made by GM that it would be exclusive to GMC and Cadillac's Suburban siblings Yukon XL and Escalade ESV. The packaged trim went on sale in July 2018. The RST package option became a level trim with the twelfth generation Suburban for the 2021 model year.[191]

There was no diesel variant of the full-size SUVs for the 2015-2020 model year versions.[192] GM offered another off-road variant or trim for the Suburban and Yukon XL starting with the eleventh generation.[193] With the relaunch of the Z71 package in the Suburban for the 2015-2020 models, GM filed papers to trademark the Trail Boss name for use on future Chevrolet truck and SUV models, although they were never used for the Suburban trims.[194]

On November 4, 2013, Chevrolet unveiled a concept design for the Suburban called the Half-Pipe, whose features include roof racks and crossbars to mount skis, at the SEMA Show. Afterwards, Chevrolet made its parts available for order at Chevrolet Accessories.[195]

At the 2017 SEMA Show, a 4x4 off-road Suburban concept inspired by Country singer (and Chevrolet spokesman) Luke Bryan based around his 2016 song "Huntin', Fishin' and Lovin' Every Day" was introduced, decked out in custom Hunter Bronze exterior color with Dark Carbon accents and camo graphics, a roof-mounted light rack and a custom lower fascia, a liftgate re-engineered to swing outward rather than upward and incorporates a custom spare tire mount, 22-inch wheels with 35-inch-tall tires, roof-mounted equipment carrier with a fishing rod holder, an interior design consisting of Black and Two-Tone Olive with Argon Orange, unique seating featuring Argon piping and Platinum camo-pattern perforated designs, and the "Huntin', Fishin' and Lovin' Every Day" badges (designated by symbols in lieu of the words) displayed on both the exterior and interior. The rear windows are removed. The concept was inspired by Bryan himself and collaborated with Chevrolet on this project as he is an owner of a Suburban: "Chevy has been part of our family and a part of our work life on the farm for as long as I can remember," says Bryan. "If you were a Bryan, you drove a Chevy — and I'm a longtime Suburban owner. This partnership is a natural fit for me and this unique Suburban represents everything I and my family want for our outdoor adventures."[196][197]

In 2011, Callaway Cars offered an upgraded Eaton supercharger package to the Suburban for an additional $15,995 (~$19,288 in 2021).[198]

In 2014, Callaway once again offered a supercharged version of the new 2015 K2XX Suburban.[199]

In 2015, Corsa Performance added a cat-back exhaust system package for customers looking to upgrade their K2XX Suburban or Yukon XL, which would give the 5.3-liter versions a 669% flow increase and the 6.2-liter versions a 342% flow increase.[200]

In 2018, Freedom Mobility partnered with GM to have their trucks and SUVs equipped with features that will make it accessible to disabled and visible/hearing impaired drivers or passengers. The Suburban is among the selected vehicles that will be available with this option.[201]

• Cargo/Troop Carrier Pickup (2-door, Extended Cab, or 4-door Silverado)[202]
• Cargo/Troop Carrier/Command Vehicle (4-door Tahoe)[202]
• Cargo/Troop Carrier/Command Vehicle/Ambulance (4-door Suburban)[202]

For the 2009 model year, the Suburban received the U.S. National Highway Traffic Safety Administration's (NHTSA) best rating of 5 stars in the frontal driver/passenger and side driver/passenger categories.

For the 2015 model year, the Suburban received an NHTSA rating of 4 stars overall, with the side driver/passenger categories receiving 5 stars. (Because of more stringent tests, 2011 and newer model ratings are not comparable to 1990–2010 ratings.) The NHTSA gave the 2016 models 4 stars overall in its review, similar to its review of its 2015 models.[204]

The IIHS gave the Suburban an Acceptable rating along with the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade.

The Suburban, Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade got a Good rating and a Best Pick. However, all four including the Yukon XL got a Good rating for head protection in side and seats and head restraints.

The Suburban, Chevrolet Tahoe, GMC Yukon and Cadillac Escalade earned a Good rating in the front offset. However, 2007–09 models without side airbags got a Poor rating. Models with them received a Marginal rating. 2010–14 models got a Top Safety Pick.

All of the GMT K2XX SUVs received a top safety pick, except for the Chevrolet / GMC 1500 series pickups, which have not been tested. The pickups have been tested against the moderate overlap test, for which they received a good rating.
