Now, just a month from the show, Auto Bild has a similar report, sketching out an upmarket car but on a different platform. Back when we drove it, the Quattro concept was built on a spaceframe based on the RS5 platform and got its go from a 2.5-liter five-cylinder engine with 380 horsepower and 354 pound-feet of torque (the show car got 408 hp from a turbocharged five-cylinder). The June report from Auto Zeitung said this new reveal would be powered by a modified version of the twin-turbo 4.0-liter V8 from the RS7 that would put out something like 650 hp. Auto Bild, on the other hand, reports that the engine will be tuned to something like 600 hp and the new concept will ride on an "enhanced" version of the A6 platform.
Both reports agree that the car we'll see will preview Audi's new design language with "tauter, more angular lines." Lightweight and exotic materials will be used in efforts to reach a supposed target weight of 1,200 kilograms (2,640 pounds), down from a target of 2,900 pounds in earlier report. Auto Bild says that Audi still hasn't decided whether to make a production version, but if they are correct about the direction of the concept, any retail offering based on it isn't going to be cheap.
