Because cars with rear-wheel drive not only don't torque steer (front wheels, upon hard acceleration, fighting the driver's navigating intentions), but have a more natural feeling both entering and leaving a turn.
The signature piece in this car is the all-wheel-drive system, which can shunt most of the engine torque to the rear wheels as necessary and will direct more torque to the outside rear wheel in a corner to help null out understeer.
Torque steer (the tendency of front-wheel drive cars to pull to the side upon acceleration) is a problem with the Beetle, especially when you have a heavy right foot like I do.
The car is notable both for its four motors (a pair at each axle integrated with max-efficiency gears to drive all four wheels at the same time) and its prowress: 526 horsepower and 649 pound-feet of torque, with a 0-60 mph time of 4 seconds.
