Audi has released some details about the quattro version of its A1 compact hatchback, of which a prototype is currently undergoing testing on snow-laden roads around Montreal in Canada. Not only will the new version ensure that quattro has full representation across the Audi range, but it also brings all-wheel-drive to the premium subcompact hatch segment for the first time.
No word yet on which engines will be offered with quattro, but we’d bet on the new 1.4 TFSI petrol version offering the option and, of course, the system also paves the way for the creation of a much hotter S1 version. The all-wheel drive system is also expected to find its way into the VW Polo R model – and easy transition as the A1 and Polo share a platform.
The A1 quattro uses technology 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.
