Speed designations on the gear selector of an automatic transmission:
* P (Park) – Parking: The transmission is locked to prevent the vehicle from moving.
* R (Reverse) – Reverse: the car moves backwards.
* N (Neutral) – Neutral: the engine is running, but the gear is not engaged, the car is not moving.
* D (Drive) – Forward movement: the car moves forward in all gears.
* L (Low) – Low gear: The vehicle moves forward in a lower gear, which provides more power and torque.
* S (Sport) – Sport mode: The transmission holds gears until higher engine speeds, providing faster shifts and a sportier driving experience.
* + (Plus) – Manual mode (upshift): the car shifts to a higher gear when the selector is moved towards the plus sign (+).
* – (Minus) – Manual mode (downshift): the car switches to a lower gear when the selector is moved towards the minus sign (-).
Additional designations:
* Tiptronic is a manual transmission control system that allows the driver to change gears manually using the steering wheel paddles or gear lever.
* CVT (Continuously Variable Transmission) is a continuously variable transmission that provides smooth shifting between gears without noticeable steps.
* DCT (Dual-Clutch Transmission) is a dual-clutch robotic gearbox that provides fast and smooth gear changes.
