Teewave AR1 (2011) - Gordon Murray's roadster unveiled

It may have a daft name - let's face it, driving a car called a Teewave does sound terrifically uncool - but Gordon Murray Design's latest creation is a very important vehicle. The Teewave AR1 not only showcases the Surrey-based company's design and engineering capabilities that elevate it to full design studio status, but also illustrates the very sweet spot where engineering integrity, lightweight material and want-one design meet. We joined design director Barry Lett at GMD on the day Project T32 was being primed for shipment to Tokyo for its public debut by Toray.

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.
