Chevrolet's factory feature sheet makes electronic fuel injection standard on the 2.5-liter four-cylinder Sport Coupe and lists a four-speed manual as standard on Sport Coupe but a five-speed manual on Berlinetta and Z28.
This is an important drivetrain-development year because electronic fuel injection and five-speed manual availability spread beyond the 1982 launch specification.
The powertrain and identification notes below preserve configuration and model-year boundaries rather than treating every 1983 Camaro alike. Ratings use the measurement convention of their period, and visual cues are only a starting point: the VIN, factory labels, drivetrain identifiers, and surviving documentation should agree.
