Chevrolet Astro

The Astro and Safari were introduced for the 1985 model year as the first minivan from General Motors. While marketed as a response to the first-generation Chrysler minivans, GM selected a rear-wheel drive layout, sizing the Astro and Safari closely to the short-wheelbase Chevrolet G10 van. Similar to the Ford Aerostar, to reduce production costs, GM adapted light-truck powertrain components; engines and transmissions were sourced from the Chevrolet S-10, allowing for a towing capacity of up to 5,500 lb (2,500 kg).

Prior to its use on a minivan, the Astro nameplate was used twice by General Motors; in 1967 (for the Chevrolet Astro 1 concept car)[2][3] and from 1969 until 1987 (on the GMC Astro COE semitractor). GMC sourced the Safari nameplate from Pontiac (used by the latter to denote station wagons). As GMC was half of the Pontiac/GMC Division (later including Buick), from 1985 through 1989, both GMC and Pontiac Safaris were simultaneously offered through the same dealership network.

Initial advertising boasted that it was a vehicle that will "make you realize that life is too big for a minivan", referring to the Chrysler minivans. The van can have a seating configuration between two and eight passengers.

Engine choices ranged from a 98 hp (73 kW; 99 PS) 2.5 L four-cylinder to a 200 hp (149 kW; 203 PS) 4.3 L V6, depending on options and/or model year. The 4-cylinder engine was only offered in cargo versions of the Astro; it was dropped after 1990. For 1985, the 4.3l V6 (RPO LB1) used a 4-barrel carburetor. For 1986 throttle body fuel injection (TBI) was used. For 1992 and later years, a central port injection was used.

Much like the second-generation F-body 1970-1981 and X-body vehicles, the GM M-van (Astro/Safari) had a bolt-on subframe. For the M-van, the front suspension shared most components with the GM B-body station wagon (Chevrolet Caprice, Oldsmobile Custom Cruiser and larger variants of the Pontiac Safari and Buick Estate Wagon) with a leaf-spring rear suspension. The lower ball joints were larger than their B-body counterparts (similar to the 1977-96 Cadillac D platform vehicles, e.g., Fleetwood limousines). These ball joints were later used in the final Chevrolet Caprice 9C1 (police package) cars manufactured in 1995 and 1996. They also shared many mechanical similarities to the GMT 325/330 midsize S/T pickups and utility vehicles.

Digital dashboards were offered in the first-generation Astro; this option did not continue after 1995.

1989 was the final year that the Borg Warner T-5 manual transmission was made available. All subsequent models were equipped with 700R4/4l60 automatic transmissions through 1993.

In 1990, a new all-wheel drive (AWD) system (the first U.S.-built minivan to do so),[4] designed and developed by FF Developments (FFD),[5] was made optional. The AWD models had a lower fuel economy: 17 miles per gallon on the highway versus 20 to 21 miles per gallon for rear-wheel drive vans. AWD Astros used a Borg Warner 4472 transfer case.

The 1990 model year also introduced a new analog dashboard and the hydroboost braking system, a system using the same accessory belt-driven pump to supply the power steering and brakes. In mid-1990 an extended body option, sharing its wheelbase with the shorter version, also became available.[6]

In 1992, a new optional door form was introduced, colloquially known as Dutch doors. This form was two bi-parting doors with a flip-up window above. Previously, Astro and Safari vans were equipped only with bi-parting doors. An optional 4.3 L (RPO L35) engine with central port injection and a balance shaft was phased in.

In 1993, the electronically-controlled 4L60E 4-speed automatic transmission with overdrive became standard as the sole transmission offering. As with many other 1993 model year GM vehicles, Scotchgard fabric protection also became a standard feature on Astro vans equipped with cloth seats. 1994 also saw the addition of three new exterior paint colors. These colors were Indigo Blue Metallic (#39), Light Quasar Blue Metallic (#20), and Medium Quasar Blue Metallic (#80).

For the 1994 model year, GM started manufacturing most of their vehicles, including the Astro and Safari, with CFC-free air conditioning systems, which used R134a refrigerant instead of R-12 refrigerant.

In 1995, the model was facelifted with an extended nose that resembled the then-new full-size Express vans; while the original rectangular sealed beam headlights were retained for use on lower trim levels, higher-spec models now used horizontally-mounted rectangular headlights that had debuted on the full-size trucks in 1988, and would eventually appear on the smaller trucks in 1998. Also for 1995, the shorter length body was dropped. In 1996, a redesigned dash received a passenger-side airbag. The vans remained mostly unchanged until the end of production in 2005.

In 2003, GM upgraded the chassis of both the Astro and Safari with certain suspension components, larger brakes, and six-lug, 16 inch wheels from the full-size Chevrolet and GMC half-ton pickup trucks.

Production in 1998 totaled 32,736 units.[1] However, sales from that point were decreasing and the second-shift production was eliminated in the summer of 2000.[1] Sales of the Astro totaled only 15,709 in 2003, down about 16% percent from 2002.[1] By 2004, production at the Baltimore facility was not enough to keep it going.[1] Sales of these models continued on a downward trend and the calculus necessary to upgrade the vans for the new 2005 safety standards was not positive.[1]
