The F355 GTS was a masterful piece of engineering as its 109 hp/litre specific power output attests. The latter value and its impressive torque were achieved by adopting a new five-valve cylinder head. The car's
3496 cc engine punched out 380 hp. Its blistering performance figures were the result of aerodynamic honing that focused specifically on the underbody.
The two-seater targa-topped F355 GTS had an aluminium and steel
body. Its styling was moulded around an aerodynamically severe design that included a full-body undertray designed to equalise downforce (Cl) between the two axles. The cabin was designed with both safety and driving pleasure
in mind. The seats and trim were Connolly leather. Composite racing seats were also available to order. The chassis was a steel monocoque with a tubular steel rear sub-frame for the engine-suspension assembly. Both front and
rear suspension used independent unequal-length wishbones and coil springs over gas-filled telescopic electronic dampers with two settings. The car also has anti-roll bars.
