Focusing on lightweight through materials and design, the new Quattro is expected to weigh in under 3,080lb (1,400kg). The light-weight program could include motorsports-inspired touches like polycarbonate in place of some of the glass, reports Auto Motor & Sport, as well as thinner glass elsewhere and extensive use of aluminum.
Lightweight but large wheels – 19 or 20in – are planned, as are ceramic brakes and possibly an active rear spoiler. At each corner a magnetic-ride suspension will dynamically adjust to the conditions and whim of the driver, while the quattro sport differential keeps the AWD system at maximum traction.
Both a twin-turbo V6, rated at 425hp (317kW) and a twin-turbo 2.0L four, rated at about 300hp (223kW) are on the short list, though the 2.5L five-cylinder out of the TT-RS would be the most authentic choice, matching the cylinder count and displacement of the second-gen Quattro, built from 1987 to 1991. If Audi goes that route, output could be as high as 375hp (280kW).
