A hybrid vehicle uses two or more distinct types of power, such as an internal combustion engine and an electric motor.
The designation of AWD is becoming narrowed, to apply to vehicles with drive train systems that have permanent drive and usually include a differential between the front and rear drive shafts.
Horsepower (hp) is a unit of measurement of power (the rate at which work is done).
Torque, moment, or moment of force is the tendency of a force to rotate an object about an axis, fulcrum, or pivot.
A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.
A turbocharger, or turbo (colloquialism), from Greek "τύρβη" ("wake"), is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.
In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions.
