DESC: More-potent engines arrived, a Z26 with new Quad 4 engine replaced the GT/GTZ, and a 4-speed electronic automatic transmission joined the 3-speed. The new 2.2-liter 4-cylinder engine made 120 horsepower (up from 110), and the available V6 gained 20 horsepower (now rated at 160). The dual-overhead-cam 2.3-liter Quad 4 engine, installed in the Z26 coupe, developed 170 horsepower. The new electronic 4-speed automatic was the sole transmission choice for Berettas with V6 power. Door-mounted front shoulder belts replaced the former manual seatbelts.
