This might be the first English driving report with the Audi A1 1.4T FSI quattro prototype. Do yourself a favor and read it!
Sourced from Swedish-manufacturer Haldex, this particular version of quattro operates under normal conditions as a front-wheel drive vehicle… that is until slip is detected. When those front drive wheels spin a hydraulic clutch style center differential mounted ahead of the rear axle sends power to the rear.
Audi had two pre-production prototype Audi A1 quattros on hand at its recent Fascination quattro winter driving event held at the Mecaglisse Test Track near Mont Tremblant, Quebec. Though not yet in series production, Audi has built any number of running test mules and these particular two examples are essentially production finish and are said to have been prepared specifically to see duty as personal evaluation vehicles for Audi CEO Rupert Stadler and Volkswagen Group Chairman Dr. Martin Winterkorn.
