Compared to its predecessor, the BB 512i has undergone a number of detailed changes. The front bumper has been fitted with an aerodynamic spoiler following studies in Pininfarina’s brand-new wind tunnel. This improves stability at high speeds. The front indicators slide into the thin blade of the bumper and the rear lights are now round in pairs of two instead of three. A Naca air intake has been added to the lower flanks in front of the rear wheel to optimise brake cooling. The roof was also slightly modified, as a result of the wind tunnel work. To give the car a better foothold on the ground and further improve its handling at high speeds, the wheels were made wider and the same size at the front and rear, making the body 3 cm wider.
