With a flat undertray, but without any obvious aero aids, the 458 generates more downforce than the F430 (360kg flat out) and yet it is also more aerodynamic.
One obvious change from the styling of the car it replaces is that the intakes for the engine bay cooling have been moved from the car’s rear flanks to the undertray, improving the overall efficiency and the operation of the rear diffuser.
The striking air intakes on the 360’s and F430’s rear haunches have been dropped in favour of a triangular intake that blends into the tapering windowline. It's a more elegant solution. Clever aerodynamics haven’t harmed the beauty of the car: the distinctive vent that leads up to the headlight allows in air to cool the brakes and then feeds it out of the channel on the other side to reduce lift over the front arches.
Then there are the inlet wings. These angle air upwards so enough is pushed through the radiators at low speeds but they then deform to reduce drag at higher speeds, when you don’t need such a large inlet area for adequate cooling. These wings also generate downforce.
Ferrari says the small lip on the boot provides plenty of downforce, and a movable wing is not necessary. We never found any reason to disagree.
