In festivities on the eve of the Internationale Automobil-Ausstellung (IAA – International Automobile Exhibition), also known as the Frankfurt Motor Show, the Volkwagen Group took the wraps off of the Audi nanuk quattro concept, an apparent derivative of the Giugiaro Parcour concept shown earlier this year. The nanuk quattro (Audi’s spelling) has AWD and unlike the Parcour it is powered by a diesel engine, turbocharged. The 4,189 lb vehicle is said to be capable of 3.8 second 0-60 runs and a top speed of 190 mph, with overall fuel economy of 30 mpg. The engine is a V10 with twin turbos and TDI and it puts out 544 horsepower, which doesn’t sound that impressive these days, but being a diesel it brings the torque, 738 pounds feet. It features Audi’s next generation of adaptive air suspension with that the driver can adjust up or down through a range of 2.76 inches. Four wheel steering has been making a comeback lately over at Audi’s VW Group stablemate Porsche, and the nanuk features something similar that Audi is calling integral steering. Rear wheels turn up to 9 degrees opposite to the front wheel’s direction to quicken steering at low to medium speeds, helping maneuverability. The wheelbase is effectively shortened by ~100 centimeters (about 40 inches), reducing the turning circle to roughly 10 meters (32.81 ft). At higher speeds, the rears turn up to 2.5 degrees in tandem with the fronts,  effectively lengthening the wheelbase by about 140 centimeters which is said to enhance stability.
