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 2.5L four-cylinder to a 4.3L V6, depending on options and model year. The 4-cylinder engine was only offered in short-length, rear-wheel-drive cargo vans, as well as passenger vans for 1985 only; 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 Astro/Safari (internally designated as the M-body for RWD models or L-body for AWD models) 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 mid-size 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
BorgWarner 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), designed and developed by
FF Developments (FFD), 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 BorgWarner 4472 transfer case. The 1990 model year also introduced a new analog dashboard and the 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. 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 4.3L V6 (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 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). The Astro and Safari also received center high mount stop lamps for 1994, which had been mandated on light trucks for the model year.
