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.
