Front-wheel, rear-wheel, and all-wheel power delivery
Front-wheel drive (FWD) powers the front wheels, which steer and propel the car. This concentrates complexity in the front, making interior space efficient and packaging compact. Rear-wheel drive (RWD) powers the rear wheels, leaving the front free to steer; RWD offers better weight distribution and handling precision but costs more and sacrifices interior space. All-wheel drive (AWD) distributes power to all four wheels in a fixed or variable ratio, improving traction in snow and off-road conditions by engaging all available grip.
Handling characteristics and driver experience
FWD vehicles tend to understeer (plow straight when pushed beyond grip limits), which is forgiving for untrained drivers but less rewarding for spirited driving. RWD cars can oversteer (tail slides out), demanding higher skill but offering tighter, more responsive control. AWD adds weight and complexity but distributes load more evenly, often combining the safety of FWD with improved cornering compared to FWD alone. Performance drivers favor RWD for precision; practical buyers favor FWD for interior space and affordability. AWD commands a premium for its all-weather capability.
Traction, torque steer, and seasonal performance
In snow, AWD accelerates grip by engaging multiple wheels rather than spinning a single axle. FWD still accelerates grip and loses less traction than RWD on ice because engine weight sits over the driven wheels. RWD struggles most in slippery conditions without weight in the rear. A phenomenon called torque steer affects powerful FWD cars: asymmetric tire grip causes the steering wheel to jerk under hard acceleration. RWD and AWD avoid this through symmetrical torque paths. Choice among these drivetrains depends on climate, budget, and desired driving experience.
