Audi A1 Quattro models ‘on the way’

Audi has confirmed it is testing four-wheel drive Quattro versions of the A1 – indicating an imminent expansion of Audi’s supermini range. Although showcased as this one-off at a Quattro publicity event in Montreal, Canada, to celebrate 30 years of the all-corner drive system, Ingolstadt acknowledged at last autumn’s 2010 Paris motor show that Quattro versions of the A1 were in the pipeline. The production A1 Quattro will use the Haldex differential to split drive to both axles; it’s a similar technology to that found in A3 and TT Quattros, as opposed to the mechanical Torsen diff found in larger Quattro models.
