Rumors of Audi's plan to resurrect the Ur-Quattro continue to persist, with Auto Motor und Sport reporting that the highly modified A5 is due to arrive sometime next year.

According to the German pub and coinciding with earlier reports, Audi plans to bring the curb weight down to around 3,000 pounds by using scads of aluminum along with polycarbonate windows in place of their glass counterparts. Further weight reductions will come from a lightweight set of 19- or 20-inch wheels and carbon ceramic brakes, while an active rear spoiler, magnetic-ride suspension system and a raced-out interior are rumored to be part of the package.

Naturally, Audi's all-wheel drive system will be the centerpiece of the reborn Ur-Quattro, but there's still plenty of questions surrounding the coupe's powertrain. Audi has supposedly decided to nix the idea of fitting its 4.2-liter V8 and will instead use either a new, twin-turbocharged V6 (odd, considering the automaker put all its efforts into creating a 3.0-liter supercharged V6 for the new S4 and A6) or possibly the 2.5-liter five cylinder currently fitted to the TT-RS in a historical nod to the new Ur's ancestry. If AMuS is to be believed, expect output somewhere between 300 and 425 hp – and there's also talk of a hybrid variant that would allow for a 20-mile electric-only commute (something about a snowball comes to mind...). Regardless, if the Ur-Quattro does come to fruition, expect it to debut sometime next year to coincide with the original's 30th anniversary, with pricing set considerably north of the current S5.
