Bottom breather

A bottom breather is a front-engine automobile that takes in air from below the front fascia (nose) rather than through a conventional grille at the front of the vehicle.[1] This styling can provide a more aerodynamic front end, or the appearance of better aerodynamics, or the look of a rear-engined sports car such as the Porsche 911, which also lacks a front grille.

Studebaker Avanti

Unlike the 911, however, most of the vehicles that use this approach have the engines installed in the front, with a water cooled radiator installed. The airflow from below the bumper is then directed into the radiator to aid in engine cooling, which makes this approach unusual in that a traditional front grille was an evolution from installing the radiator externally for vehicles manufactured since the early days of automobile production. Some of the most well known bottom breathing automobiles are the Citroën DS, Chevrolet Corvette C4, Studebaker Avanti, Honda Logo, Infiniti Q45, Volkswagen Passat, and the Ford Taurus.[1]

Some vehicles disguise the lower air intake with a grille above the bumper which is not functional, like the Dodge Avenger coupe and Chrysler Sebring of the same generation.
