The Car Performance and Car Tuning

A performance car is a vehicle that is designed and constructed specifically for speed.The design and structure of a performance car involves not only providing a capable power train but also providing the handling and braking systems to support it. Performance cars are road vehicles, capable of providing transport.  Specially designed racing cars are not normally regarded as performance cars, but  performance cars are often raced.

Meanwhile car tuning is modification of the performance or appearance of a vehicle. Tuning, on the other hand, has become a way to personalize the characteristics of a vehicle to the owner's preference. Cars may be altered to produce more power, or to provide better handling.

Tuned cars are built for the pleasure of owning and driving. Exterior modifications include changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, spoilers, air vents and light weight wheels. Engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, Mass air flow/ Volume air flow, etc. Modern engines employ the use of an ECM to  provide the best balance between performance and emissions Via the OBD.
