Audi has plans to launch a Quattro AWD version of the A1 hatchback. The Audi A1 quattro will be the first car in premium subcompact hatchback segment to feature all-wheel-drive. Here a developmental prototype of the car is shown testing on Canada’s densely snow-packed roads in Montreal.
The A1 Quattro testing program is a part 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.
The Quattro system of the A1 is very similar to that used in A3 and TT models. At its core is an electronically controlled, hydraulically actuated multi-plate clutch located in front of the rear axle for an optimized distribution of weight. Inside is a package of plates that rotate in an oil bath.
During normal driving, the clutch sends most of the engine’s power to the front wheels. If the front axle loses grip, the clutch can instantly transfer torque to the rear axle by forcing the plate packages together. A pressure reservoir helps the electric pump to develop the necessary oil pressure.
Audi wants to have a Quattro version of all cars in the range. That’s probably the only reason this car is in development! You don’t really need all-wheel-drive in a small hatchback like this,but it’s cool to have it anyway.
