Drivetrain and terrain

104 articles · Page 1

This section covers how a car is built to move and how that plays out on real roads. Articles compare drivetrain types — AWD versus 4WD, AWD versus FWD in winter — and separate genuine off-road capability from common 4WD myths. Others look at suspension choices, including active and adaptive systems and air springs versus coils, plus transmissions such as CVTs and automatics against manuals, and brakes from discs to drums. A second group of guides matches vehicles to conditions: snow, mountain roads, desert and hot climates, rural driving and long distances, along with tires, tire pressure monitoring and exterior durability.

Frequently Asked Questions

What is the difference between AWD and 4WD?

AWD systems send power to all four wheels automatically and are tuned mainly for traction on slippery pavement. 4WD systems are typically driver-selected and built around low-range gearing for off-road use. Articles here compare the two for snow, mountain roads and rough terrain.

Do I need winter tires if my car has all-wheel drive?

All-wheel drive helps a car accelerate on slippery surfaces, but it does not shorten braking distances or improve cornering grip. Tire compound and tread do that work, which is why all-season versus winter tires is treated as a separate decision from drivetrain choice.

Is adaptive or air suspension worth the extra cost?

Adaptive and active suspension can widen the gap between comfort and body control, which matters most on long drives and broken surfaces. The tradeoff is added complexity and higher repair costs compared with conventional coil springs. The guides here weigh those gains against the failure modes owners actually report.
