The Ferrari F355 (Type F129) is a sports car manufactured by Italian car manufacturer Ferrari produced from May 1994 until 1999. The car is a heavily revised Ferrari 348 with notable exterior and performance changes. The F355 was succeeded by the all-new Ferrari 360 in 1999. Design emphasis for the F355 was placed on significantly improved performance, as well as drivability across a wider range of speeds and in different environments (such as low-speed city traffic). Specifications Apart from the displacement increase from to , the major difference between the V8 engine in the 348 and F355 is the introduction of a 5-valve cylinder head. This new head design allowed for better intake permeability and resulted in an engine that was considerably more powerful, generating a maximum power output at 8,250 rpm and of at 6,000 rpm. The longitudinally mounted 90° V8 engine was stroked by 2 mm over the 348's engine (77 mm rather than 75 mm), resulting in the small increase in displacement. Engine internals are produced using lightweight materials; the connecting rods are forged in Ti6-Al-4V titanium alloy. The engine's compression ratio is 11:1 and employs the Bosch Motronic 2.7 engine control unit in the 1995 model year, later changed to the M5.2 in 1996 through end of production. The Motronic system controls the electronic fuel injection and ignition systems, with a single spark plug per cylinder. Engine lubrication is via a dry sump oiling system. The engine was designed by Paolo Martinelli. The F355 addressed transmission issues that plagued the earlier models. A coolant heat-exchanger was installed which upon startup, warmed the gearbox oil quicker. A rod-driven actuation system, which replaces the 348's cable operated system, was also added for precise gear shifts. The frame is a steel monocoque with tubular steel rear sub-frame with front and rear suspensions using independent, unequal-length wishbones, coil springs over gas-filled telescopic shock absorbers with electronic control servos and anti-roll bars. The car allows selection between two damper settings, "Comfort" and "Sport". The road-going models came with Pirelli tyres, size 225/40ZR 18 at the front and 265/40 ZR 18 at the rear. Although the F355 was equipped with power-assisted steering (intended to improve low-speed drivability relative to the outgoing 348), this could optionally be replaced with a manual steering rack setup by special order. Aerodynamics for the car included over 1,300 hours of wind tunnel analysis. The car incorporates a
