The all-wheel drive technology used on the A1 prototype is very similar to that found in A3 and TT models. At the heart of the system is an electronically controlled, hydraulically actuated multi-plate clutch located in front of the rear axle. Under normal driving conditions, the clutch sends most of the engine’s power to the front wheels. If the front axle starts losing traction, the clutch can instantly transfer torque to the rear axle by forcing the plate packages together.
The German firm stated that the one-off development car is one of the stars of the ‘Fascination of quattro’ event taking place in Montreal to celebrate the past, present and future of the legendary four-wheel-drive system, which reached its 30th anniversary in 2010.
