This was a two-seater berlinetta with all of the characteristics drivers had come to expect from Maranello. Although extremely versatile to drive, the 348 GTB really only came into its own on the track thanks to its extreme sportiness, a fact demonstrated amply in the 348 Challenge in Europe and the USA. It was styled by Pininfarina. The 348 GTB had superbly balanced, efficient lines that took a strong lead from the classic Ferrari styling cues, and sported a steel and aluminium body.
It was a particularly beautiful car too, thanks to intensive work carried out in the wind tunnel to refine its aerodynamic shape.  Its interior volumes and driver position were designed for maximum comfort given its sporty set-up, while the seats and trim were a plush Connolly leather.
The 348 GTB had a steel monocoque with differentiated tubular elements and a tubular rear sub-frame for the engine-suspension assembly.  The suspension was independent unequal-length wishbones front and rear. It had coil springs over gas-filled telescopic dampers, and stabiliser bars. The steering was rack and pinion. The car also had self-venting disc brakes with ATE antiskid.
