FAQs
What Are the Main Differences Between 4WD, AWD, and 2WD？
2WD cars, trucks, etc., power the vehicle using only 2 of 4 wheels–either front (FWD) or rear (RWD). Four wheel drive vehicles–like SUVs and 4x4s–power all four wheels for improved safety and performance in rough terrain and off-road conditions. 2WD is preferable for fuel efficiency and vehicle lifespan on highways and smooth bitumen roads. Most 4WD models switch manually between 4WD and 2WD. AWD vehicles are typically low-clearance and designed to use all four wheels for better handling at high speeds and in hazardous road conditions.
