BMW iX

The BMW iNext was first announced by BMW in March 2016 as the "new spearhead of innovation and technology" with a launch goal of early in the next decade.[9]

The BMW Vision iNext was unveiled at the 2018 Paris Motor Show. Referred as "Project i 2.0", the Vision iNext was developed to address key questions for the future of motoring, with a focus on electrification, connectivity and autonomy. It was an SUV roughly similar in size to the BMW X5, although it was substantially bigger inside due to its EV architecture, with front and rear motors and underfloor batteries. BMW confirmed that it would use BMW's fifth-generation electric powertrain, 0–100 km/h (62 mph) in 4.0 seconds and range of 380 mi (612 km). The level of autonomy the production version would offers depended on regulations and infrastructure.[10]

The production variant, the BMW iX, was officially announced in November 2020.[11]

The BMW iX was released in June 2021 as a 2022 model, alongside the BMW i4. Sales began in November 2021. At launch, BMW indicated the release was part of an ongoing effort to reach a 50% global share of the electric vehicle market. The BMW iX was announced to be manufactured at the BMW Group Plant Dingolfing.[12]

A performance model, the iX M60, was released in May 2022.[13]

The BMW iX is built on a bespoke electric drivetrain architecture and an aluminum spaceframe with carbon fibre reinforced plastic (CFRP) side frame, rain channels, roof frame and rear window aperture.[14] The electric platform is a "totally new development", though it is "highly compatible" with the modular CLAR platform. This shared chassis componentry allows BMW to produce the iX alongside cars with combustion engines at the Dingolfing plant.[8]

The body is made out of a combination of high-strength steel, aluminium, thermoplastics and carbonfibre-reinforced plastic (CFRP) to keep weight as low as possible.[15] Underpinning the iX is an aluminium-intensive chassis featuring a double-wishbone (front) and multi-link (rear) suspension, offering active rear-wheel steering.[8] The front features a large blanked off grille, which contains camera, radar and other sensors needed for the driver assistance systems.[16] The grille comes with a self-healing coating that can smooth-out scratches and small chips to make sure that the sensors can always "see" clearly.[17]

The iX resembles the G05 X5 in length and width, but with the lower roof height of an G06 X6 and the larger wheel size of an G07 X7.[18] It has a 0.25 drag coefficient and a 2.82 m² frontal area (thus CdA=0.71m²). BMW says the vehicle's low aerodynamic profile improved its WLTP range by around 40 miles.[16] The iX features a fixed clamshell-style bonnet. The windscreen washer bottle is accessed via the BMW emblem above the grille.[8]

The iX utilise BMW's fifth-generation scalable electric drivetrain that is developed in-house.[19] The electric powertrain combines the electric motor, power electronics and single-speed transmission in a single housing. The power density of the system is around 30 percent higher than previously, according to BMW.[8] The electric motors operate without the use of cobalt that makes the motors in the iX spin using electricity alone, instead of permanent magnets making the rotor spin around the stator. BMW claims its fifth-generation eDrive technology is 93 percent efficient. There is still some cobalt used in the lithium-ion batteries.[20]

The iX's default regenerative braking mode utilizes adaptive recuperation. With the help of GPS data and sensors, Adaptive mode adjusts the regen to be more aggressive in urban traffic and less so on open roads, where it allows coasting.[21] There are three levels of adjustable regenerative braking: high, medium, and low. The high setting essentially enables one-pedal driving as all the braking is achievable regeneratively, while the low level amounts to a very modest amount of energy recovery to get close to a traditional coasting experience.[22]

The batteries consists of prismatic cells and has a standard 400 V battery system. According to BMW, the gravimetric energy density of the lithium-ion battery has been increased by around 20 percent compared to the previous generation. The vehicle has a thermal management system featuring heating and cooling with heat pump, and a battery pre-conditioning feature ahead of fast charging.[23]

The xDrive40 is able to DC fast charge up to 150 kW using a CCS connector and the xDrive50 up to 200 kW, with both being able to charge 10–80 percent in less than 40 minutes.[6] As for home charging, an 11 kW charger can fully charge the battery from empty in around 11 hours.[16]
