The Astro is a rear-wheel drive minivan or van manufactured by General Motors, also sold under the name GMC Safari. Depending on the modification and purpose, the car can accommodate from two to eight people. Since the 1990 model year, all-wheel drive has appeared. In 1993, an elongated model was released, elongated by 25 cm compared to the standard one, which increased the cargo volume by more than half a cube. The Astro was equipped with a 4.3-liter V-6 petrol engine. In some versions of the cargo and cargo-passenger Astro, until 1990, a 2.5-liter four-cylinder engine was installed.
In the passenger version, the Astro offered many comfort options, and the design, justifying the name, was truly “cosmic”: an electronic instrument cluster, a multifunctional overhead console, a convertible interior, etc. The second row has revolving seats (three-seat sofa or two separate chairs), cup holders front and rear, plenty of storage compartments: pockets on the front passenger doors, drawers in the rear armrests and drawers under the front seats. All rear seats can be folded down or completely removed (the only negative is that they are heavy). The equipment includes a standard AM / FM radio with front speakers, in more expensive trim levels a powerful stereo radio with graphic equalizer and rear speakers is installed. In the luxury version, the car has air conditioning in the back. The buyer was offered a wide choice of body colors, including two-tone color in different versions, wheel covers and alloy wheels, chrome trim, leather interior. In 1990, the Chevrolet Astro received a restyled panel.
The Astro had two engine options depending on trim or model year. For commercial versions, as already mentioned, the base was a four-cylinder 2.5-liter Tech IV engine – it had a power of only 98 hp. In addition, a 4.3-liter V6 petrol unit was offered. Only this motor was installed in the passenger Astro and was offered in two power levels: 165 hp. or 200 hp in later versions with an injection system. The V6 engine was combined with either a 5-speed “mechanics” or a 4-speed “automatic”. The volume of the tank is 102 liters.
The Chevrolet Astro chassis uses design solutions adopted in GM station wagons since the 70s, therefore it was distinguished by strength and reliability: an integrated body frame with powerful box section spars, a bolted subframe, and reinforced ball joints. Front independent suspension with coil springs, rear spring. In addition to rear-wheel drive, a four-wheel drive system soon appeared with torsion bars in the suspension and a Borg Warner transfer case.
The braking system includes front disc mechanisms and rear drum mechanisms. The Chevrolet Astro minivan could easily take on board up to 800 kg. Depending on the configuration of the cabin and the length of the body, the luggage space is from 2.4 to 4.83 м3. The maximum towing capacity was estimated at 2.7 t, and when towing a trailer without brakes – 905 kg. The rear door of the Chevrolet Astro is either a conventional double-leaf hinged door or the so-called “Dutch” door: a rising upper section and double doors at the bottom. The second option was considered more convenient both in terms of loading and looking back (solid glass without frames). In addition, these doors relied on the rear wiper and glass heating.
Chevrolet Astro was equipped with power steering and vacuum brake booster (except for the most inexpensive versions at the beginning of production). The vehicle has three-point seat belts in the front and lap belts in the rear. Modifications since 1990 have offered anti-lock brakes. From model year 1993, the car could be equipped with a driver’s airbag. However, the Astro did not perform well in crash tests, with a “poor” rating from the IIHS and only one star from the NHTSA.
Astro rightfully belongs to the legendary American “vans”. He acted as a rival not only for competing models from Chrysler, but also as an alternative to more modern and comfortable Japanese minivans that were starting to conquer the market. Astro could easily be adapted to a wide range of tasks, had good equipment, but not the highest quality failed – the most frequent problems were with the suspension and steering, although in general the car was distinguished by its simplicity of design and maintainability.
