Launched in spring of 1996, this was BMW's first sports car in 40 years. Based on the 3-Series chassis, the racy-looking 2-seater Z3 was produced at BMW's plant in South Carolina. Wheelbase was shorter than the 3-Series, which lent many drivetrain and other components to the roadster. Only a 4-cylinder engine was available initially. The 1.9-liter dual-cam 4-cylinder engine produced 138 horsepower. A 5-speed manual transmission was standard, with 4-speed automatic and traction control optional. Standard equipment included dual airbags, antilock 4-wheel disc brakes, a limited-slip differential, and 16-inch tires on alloy wheels. The manually operated convertible top had a plastic back window.
