The drivetrain is a system of components—the engine, transmission, driveshafts, geared differentials, and drive axles—working together to generate power and deliver it to the wheels.

Automatic Transmission
The automatic transmission receives power (torque) created by the engine and sends it to the differential. Inside the transmission is a collection of gears that, based on vehicle speed and driving conditions, change automatically in order to keep the engine operating most efficiently. More >>

Manual Transmission
The manual transmission receives the power (torque) created by the engine and sends it to the differential. During vehicle operation, the driver operates the clutch and moves the gear stick in order to select the best gear based on vehicle speed and driving conditions. More >>

Key Component — Engine

The engine is a mechanical device designed to convert chemical energy (fuel) into kinetic energy (motion), which powers your vehicle. Almost all vehicles (including hybrids) use internal combustion engines that burn fuel. In an internal combustion engine, air and fuel are ignited inside a cylinder and the pressure that is created forces pistons to move up and down. This rotates the crankshaft, which delivers power to the wheels via the drivetrain. More >>
