An AWD vehicle (short for All-wheel drive vehicle) is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand.It appears in everything from supercars with out-of-this-world performance like the Audi R8 to family crossovers and SUVs like the Volvo XC90.
Advantages
As compared to rear wheel driven car, there is a faster and safer travelling due to good road holding on curves.
Gives sportier handling and traction to a broader range of cars.
A lower flat floor lines is provided due to dispensing with the propeller shaft resulting in lowering of centre of gravity.
The engine, clutch, gear box and final drive are combined similar to the rear engine car. This provides a more comfortable drive due to final drive spring.
Good road adhesion is obtained due to a large part of the vehicle’s weight being carried on the driving wheels under normal conditions.
