Glossary of Commonly Abbreviated Car Terms

There’s no getting around the fact that the automotive world is packed with abbreviations that can be confusing and sometimes indecipherable. At BM Spares, we want to make it easier for you to understand the terminology used when discussing car parts and features. That’s why we’ve put together this handy glossary to help you decode the jargon.

• ABS (Antilock Braking System): A safety system that prevents wheels from locking up during braking, helping maintain steering control.

• ACC (Adaptive Cruise Control): A system that automatically adjusts the vehicle’s speed to maintain a safe distance from the car ahead.

• AEB (Autonomous Emergency Braking): A safety feature that detects potential collisions and automatically applies the brakes to avoid or mitigate impact.

• AWD (All-Wheel Drive): A drivetrain that distributes power to all four wheels for improved traction and stability.

• BHP (Brake Horsepower): A measure of an engine’s power output before losses due to auxiliary components.

• CVT (Continuously Variable Transmission): A type of automatic transmission that provides seamless acceleration by using a belt or chain-driven system instead of fixed gears.

• DDI (Direct Diesel Injection): A fuel injection system that directly delivers diesel into the combustion chamber for improved efficiency and power.

• DFI (Direct Fuel Injection): A fuel system that injects fuel directly into the engine’s cylinders, increasing performance and fuel economy.

• DPF (Diesel Particulate Filter): A filter that captures and removes soot from diesel engine exhaust gases to reduce emissions.

• DRL (Daytime Running Lights or Daytime Running Lamps): Lights designed to improve a vehicle’s visibility during daylight hours.

• DSC (Dynamic Stability Control): A system that detects and reduces skidding by applying braking force to individual wheels.

• DSG (Direct-Shift Gearbox): A type of dual-clutch transmission that enables fast and seamless gear changes.

• E-REV (Extended-Range Electric Vehicle): An electric vehicle with a small internal combustion engine used to generate power when the battery is depleted.

• ESC (Electronic Stability Control): A system that helps prevent loss of control by automatically applying brakes to individual wheels.

• ESP (Electronic Stability Program): Another term for ESC, used by different manufacturers.

• EV (Electric Vehicle): A vehicle powered entirely by an electric motor and battery, without an internal combustion engine.

• FWD (Front Wheel Drive): A drivetrain where power is delivered to the front wheels.

• GPS (Global Positioning System): A satellite-based navigation system that provides location and direction information.

• HP (Horsepower): A unit of power measurement for engines, indicating performance capabilities.

• ISOFIX: An international standard attachment system for child safety seats in vehicles.

• LDWS (Lane Departure Warning System): A safety feature that alerts the driver when the vehicle unintentionally drifts out of its lane.

• LED (Light Emitting Diode): A type of energy-efficient lighting commonly used in vehicle headlights and taillights.

• LSD (Limited Slip Differential): A differential that limits the difference in wheel speeds, improving traction and handling.

• LPG (Liquid Petroleum Gas): A type of alternative fuel used in internal combustion engines.

• LWB (Long Wheelbase): A vehicle design with an extended distance between the front and rear wheels, often for increased interior space.

• NVH (Noise, Vibration and Harshness): A measure of the comfort level in a vehicle by assessing noise, vibration, and ride quality.

• PHEV (Plug-in Hybrid Electric Vehicle): A hybrid vehicle with a rechargeable battery that can be plugged in to charge.

• RPM (Revolutions Per Minute): A measurement of engine speed, indicating how fast the crankshaft is rotating.

• RWD (Rear Wheel Drive): A drivetrain where power is delivered to the rear wheels.

• SUV (Sports Utility Vehicle): A type of vehicle with higher ground clearance and off-road capabilities.

• TCS (Traction Control System): A system that prevents wheel spin during acceleration by modulating power and braking.

• TFT (Thin Film Transistor): A type of LCD screen technology used in digital dashboards and infotainment displays.

• VIN (Vehicle Identification Number): A unique code assigned to every vehicle for identification and registration purposes.
