In Automotive Engineering , a is an opening in the bodywork of a vehicle to allow air to enter. Most vehicles feature a grille at the front of the vehicle to allow air to flow over the Radiator and cool the engine compartment. Other common grille locations include below the front Bumper , in front of the wheels (to cool the brakes), or on the rear deck lid (in Rear Engine vehicles).
The grille is often a distinctive styling element, and many Marque s use it as their primary brand identifier. For example, Jeep has trademarked its seven-bar grille style. Rolls-Royce is famous for arranging its grille bars by hand to ensure that they appear perfectly vertical. Other makers known for their grille styling include Bugatti 's horse-collar, BMW 's split kidney, Dodge 's cross bar, and Audi 's new through-the-bumper style.
