1990-1993 GMC S15/Sonoma Pickup Review

Identical except for badging and trim-package designations, GMC S15 and Chevrolet S10 compact pickups held 4-cylinder or V6 engines. Short-bed, regular-cab models rode a 108.3-inch wheelbase with 6-foot cargo bed. Long-bed versions had a 117.9-inch wheelbase, with a 7.5-foot bed. Extended-cab, rode a 122.9-inch span, with the 6-foot bed. A 2.5-liter 4-cylinder engine was standard on 2WD models. Optional were two V6 engines: a 2.8-liter V6 and a 4.3-liter V6. On-demand, part-time 4-wheel drive with shift-on-the-fly operation was available on all three sizes.

Year to Year Changes

1991 GMC Sonoma: GMC replaced the S15 badge with a Sonoma designation as the compact trucks earned a facelift consisting of a new grille, wheels, bodyside moldings, and bumper rub strips. Later in '91, the base 4-cylinder engine added power. At the other end of the scale, a vigorous GMC Syclone, packing a 280-horsepower turbo V6, went on sale.

1992 GMC Sonoma: Optional pushbutton shifting became available on 1992 4WD models. Head restraints became standard for outboard bench seats.

1993 GMC Sonoma: The super-performance Syclone and its sporty GT cousin were gone. Both 4.3-liter engines got an internal balance shaft, designed to reduce engine vibrations.
