nolder profile on the upper portion of the tail and a fairing on the underbody that generates downforce when the car is at speed. The car's standard seats are upholstered with hides from Connolly leather, and are fitted asymmetrically in the car; this results in the driver being slightly closer to the car's centerline than the passenger. At launch, the only model available was the Berlinetta. The Spider (convertible version), and the GTS (targa top model) were introduced in 1995. In 1997, the Formula One-style electrohydraulic-operated automated manual paddle-shift transmission was introduced and the cars equipped with this transmission were called 355 F1. The F355 was the last in the series of mid-engine Ferrari models with the Flying Buttress rear window, a lineage going back to the 1965 Dino 206 GT, unveiled at the Paris Auto Show. The nomenclature does not follow the formula from the previous decades, i.e., engine capacity (in litres) followed by the number of cylinders (e.g. 246 = 2.4 litres, 6 cylinders, 308 = 3.0 litres, 8 cylinders, etc.). In naming the F355, Ferrari used engine capacity followed by the number of valves per cylinder (355 = 3.5 litre engine capacity and 5 valves per cylinder) to bring the performance advances introduced by a 5-valve per cylinder configuration into the forefront. Variants F355 Berlinetta The Berlinetta was introduced in May 1994, as the first in a successful series of F355 models. Initially, the 6-speed manual was the only transmission available. However, in 1997, the Berlinetta was the first-ever road car to be equipped with the innovative F1-style gearbox management system. Derived directly from Formula 1, where it made its debut in 1989 resulting in a win at the Brazilian Grand Prix, the electro-hydraulic system was operated by paddles behind the steering wheel using the F355's conventional 6-speed manual gearbox. The new transmission guaranteed faster gear changes, with the additional advantage that both of the driver's hands could stay on the wheel at all times. Ferrari produced 4,871 road-going Berlinetta models during the entire production run, of which 3,829 were equipped with the 6-speed manual and 1,042 with F1 transmissions. F355 Spider The F355 Spider debuted in 1995, its Pininfarina-penned lines honed by 1,800 hours in the wind tunnel, resulted in a blend of elegant style and aerodynamic performance. For the first time on a Ferrari automobile, the automated manual soft-top was powered electronically. Initially, the Spider
