Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
Downforce is a downwards lift force created by the aerodynamic features of a vehicle. If the vehicle is a car, the purpose of downforce is to allow the car to travel faster by increasing the vertical force on the tires, thus creating more grip. If the vehicle is a fixed-wing aircraft, the purpose of the downforce on the horizontal stabilizer is ...
Ground effect (cars) In car design, ground effect is a series of effects which have been exploited in automotive aerodynamics to create downforce, particularly in racing cars. This has been the successor to the earlier dominant aerodynamic focus on streamlining. The international Formula One series and American racing IndyCars employ ground ...
Bargeboards are pieces of bodywork on open-wheel racing cars, serving a purely aerodynamic (as opposed to structural) function. They are curved vertical planes situated longitudinally, between the front wheels and the sidepods, held away from the chassis at the front on struts or other connectors, and connecting to the sidepods or extensions of ...
The GMA T.50 or Gordon Murray Automotive Type 50 is a sports car manufactured by Gordon Murray Automotive. Designed by Gordon Murray and inspired by the McLaren F1, the T.50 is powered by an all-new bespoke 3,994 cc (4.0 L) naturally aspirated V12 engine developed by Cosworth. The engine is rated at 663 PS (488 kW; 654 hp) at 11,500 rpm with a ...
Drafting (aerodynamics) A paceline of drafting cyclists. Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can ...
Auto racing. Auto racing (also known as car racing, motor racing, [1] or automobile racing) is a motorsport involving the racing of automobiles for competition. In North America, the term is commonly used to describe all forms of automobile sport including non-racing disciplines. Auto racing has existed since the invention of the automobile.
Ram-air systems are used on high-performance vehicles, most often on motorcycles and performance cars. The 1990 Kawasaki Ninja ZX-11 C1 model used a ram-air intake, the very first on any production motorcycle. Ram-air was a feature on some cars in the sixties. It fell out of favor in the seventies, but recently made a comeback.
