During its manufacturing period from 1987 to 1996 Chevrolet introduced the front-wheel-drive two-door coupe Chevrolet Beretta which showed the engineering advancements of that era. General Motors built the Chevrolet Beretta on their L platform and customers could select between the 2.2 L OHV 4-cylinder powertrain or the 60-degree V6 engine configuration with the GT version using a 2.8-liter V6 unit which became a 3.1L engine in 1990 and produced 125 hp. The top GTZ variant of the Chevrolet Beretta used a 2.3-L high output Quad 4 inline-four engine that produced 180 hp and 160 lb-ft of torque. When the 3.1 L V6 reached 3100 V6 status in 1994 it generated 160 hp but this power dropped in 1995. Different transmission choices existed for Chevrolet Beretta models but the standard automatic transmission was only available for the base Chevrolet Beretta and the 2.2L engine required a manual transmission as its only option. The standard transmission for the 1990 GTZ model was its 5-speed manual transmission however the 3100 V6 received a new 4-speed automatic transmission during 1994. During its production the Chevrolet Beretta measured 178.2 inches in length with 103.4 inches for wheelbase while dimension changes occurred between width and height measurements. Quality and compatible Chevrolet Beretta parts can be acquired through authorized channels because these components fulfill original design parameters which help extend the Chevrolet Beretta's useful life.
