Naturally, the Quattro features the latest AWD hardware, which includes a rear-biased, 40:60 torque split and the recently introduced sport differential that distributes the power between the rear wheels at a variable rate for optimum handling. While the suspension is closely related to the RS5, the extra-large carbon-ceramic discs are straddled by six-piston calipers anodized red. The handmade 14-spoke wheels are shod with 275/30R20 Dunlop Sportmaxx tires.
"The exterior design is bold and expressive," states Egger. "It stirs emotions, brings back memories, blends the rawness of a competition car with the smoothness of a GT. The interior design takes us a relatively big step into the future. It is an object lesson of less is more. Less, as in no separate sat nav monitor, no redundant switches, no multi-functional overkill ergonomics. Simple and easy, sporty and sexy, friendly to the eye and pleasant to the touch-that's the mix we aimed to create instead. Of course, concept Quattro also forges the occasional link to its great heritage. For example, the thumb switches on both sides of the IP shout Quattro. Or the large digital speedometer flanked by the dogleg semi-analogue rev counter, which is so very mid-80s. And of course back-to-basics stuff like a round steering wheel, a real gearlever and an absolutely perfect driving position."
The bucket seats, by Sparco, weigh a mere 40 pounds each. Trimmed in soft beige leather, they offer electrically adjustable backrests, a carbon fiber frame, integrated four- or five-point belts and side air bags. Other materials used inside the cabin are brushed aluminum, more carbon fiber, and satin black leather. Via the MMI, the driver can access a large center display that provides a variety of functions from classic round instruments to rally-style pace notes coordinated by the navigation system.
In terms of the power to weight ratio, the concept Quattro just about matches the 525-hp R8 5.2 FSI. The performance and consumption figures are equally impressive. Audi reckons that the car can accelerate in 3.9 sec from 0-62 mph, top an electronically restricted 156 mph and average 33 mpg. And as far as ride and handling are concerned, the concept Quattro is bound to drive circles around the relatively twitchy Sport Quattro. Building this vehicle is a no brainer, right? Wrong.
