How AWD Systems Can Make Your Sports Car Faster, Safer, and More Fun to Drive

What is an AWD system and how does it differ from other drivetrain systems?

AWD, or All-Wheel Drive, is a drivetrain system that delivers power to all four wheels of a vehicle simultaneously. Unlike other drivetrain systems, such as Front-Wheel Drive (FWD) or Rear-Wheel Drive (RWD), AWD ensures that all wheels receive equal power, providing better traction and control.

• Front-Wheel Drive (FWD): In this system, power is sent only to the front wheels. It’s common in many passenger cars due to its cost-effectiveness and simplicity.
• Rear-Wheel Drive (RWD): Here, power is directed to the rear wheels. This system is prevalent in sports cars and trucks because it offers better acceleration and handling.
• Four-Wheel Drive (4WD): Often confused with AWD, 4WD is typically used in off-road vehicles. The main difference is that 4WD can be turned on and off, whereas AWD is always active.

AWD systems are designed to automatically adjust the power distribution between the front and rear wheels, depending on the driving conditions. This adaptability makes AWD systems superior in terms of handling, especially on slippery or uneven terrains.

However, it’s essential to note that not all AWD systems are created equal. Some are biased towards the front or rear wheels, while others distribute power evenly. The type of AWD system and its configuration can significantly influence a sports car’s performance and driving experience.
