The Ferrari Testarossa is a 12-cylinder mid-engine sports car manufactured by Ferrari, which went into production in 1984 as the successor to the Ferrari Berlinetta Boxer. The Pininfarina-designed car was originally produced from 1984 to 1991, with two model revisions following the ending of Testarossa production and the introduction of the 512 TR and F512 M which were produced from 1992 to 1996. Almost 10,000 Testarossas, 512 TRs, and F512 Ms were produced, making it one of the most common Ferrari models, despite its high price and exotic design. In 1995, the F512 M retailed for $220,000. The Testarossa is a two-door coupe with a fixed roof that premiered at the 1984 Paris Auto Show. All versions of the Testarossa had the power fed through the wheels from a rear-mounted, five-speed manual transmission. The Rear mid-engine, rear-wheel drive layout (engine between the axles but behind the cabin) keeps the centre of gravity in the middle of the car, which increases stability and improves the car's cornering ability, and thus results in a standing weight distribution of 40% front: 60% rear.
