Vehicle insurance - Wikipedia

Vehicle insurance (also known as auto insurance, car insurance, or motor insurance) is insurance purchased for cars, trucks, and other vehicles. Its primary use is to provide protection against losses incurred as a result of traffic accidents and against liability that could be incurred in an accident.

Car tuning - Wikipedia

Car tuning is both an industry and a hobby, in which an automobile, motor bike, scooter or moped is modified in order to improve its performance, handling and presentation and improve the owner's driving style. As most vehicles leave the factory set up for average driver expectations and average conditions, tuning has become a way to personalize the characteristics of the vehicle to the owner's preference. For example, they may be altered to provide better fuel economy, produce more power at high RPM or the ride comfort may be sacrificed to provide better handling.
Car tuning is related to auto racing, although most performance cars never compete. Rather they are built for the pleasure of owning and driving such a vehicle. Another major facet of tuning includes performance modification to the car exterior. This includes changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, adding spoilers, splitters, air vents and light weight wheels.

Turbocharger - Wikipedia

A turbocharger, or turbo, is a gas compressor that is used for forced-induction of an internal combustion engine. A form of supercharger, the turbocharger increases the density of air entering the engine to create more power. A turbocharger has the compressor powered by a turbine, driven by the engine's own exhaust gases, rather than direct mechanical drive as with many other superchargers.

Spoiler - Wikipedia

A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion. Spoilers on the front of a vehicle are often called air dams, because in addition to directing air flow they also reduce the amount of air flowing underneath the vehicle which reduces aerodynamic lift. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse.
Spoilers for cars are often incorrectly confused with, or the term used interchangeably with, wings. Automotive wings are devices whose intended design is to generate downforce as air passes around them, not simply disrupt existing airflow patterns.

Radar speed sign - Wikipedia

A radar speed sign (also called a driver feedback sign, radar signs, Vehicle Activated Sign (UK), changeable message sign, Your Speed sign, radar feedback sign, speed radar sign, radar speed display, speed feedback sign, traffic calming sign, speed display board, dynamic speed display (DSDS) or variable message sign) is an interactive sign, generally constructed of a series of LEDs, that displays vehicle speed as motorists approach. The purpose of radar speed signs is to slow cars down by making drivers aware when they are driving at unsafe speeds. They are used as a traffic calming device in addition to or instead of physical devices such as speed humps, speed cushions, speed tables, and speed bumps.

Carbon - Wikipedia

Carbon - fiberglass based on carbon fiber is the youngest material on the automotive aftermarket. Carbon is light weight, durable, but also a very expensive material. Unlike ordinary fiberglass, solidification of the connecting tar takes place in a pressure chamber using high temperatures. Due to the very large amount of waste during the manufacturing process, large scale producers cannot widely use carbon fiber in automobile parts production currently.
