4WD or AWD: Which drivetrain is better for off-roading
Whether to choose a 4WD (four-wheel drive) or an AWD (all-wheel drive) system on an SUV is one of the highly debated topics in the automotive industry. Both systems help deliver power to all four wheels of a vehicle.

In an AWD system, a computer determines the power distribution to each wheel based on its traction status, providing a more adaptive response to changing road conditions

On the other hand, 4WD systems require the driver to engage all four wheels manually, typically through a lever or button, based on their expertise and knowledge in assessing the driving conditions.

This fundamental difference in power distribution plays a significant role in determining the ideal use cases for each system.

Vehicles equipped with a 4WD system excel in off-roading situations due to their rugged design and the driver's ability to engage the system when faced with low-traction conditions.

In contrast, AWD vehicles are generally more fuel-efficient than their 4WD counterparts, as they often revert to a 2WD setup in normal conditions. It is because this system only sends power to all wheels, as and when needed.

Despite both systems powering all four wheels of a vehicle, AWD and 4WD cannot be used interchangeably due to their distinct mechanisms for distributing power.
