Report Card: Crossing the Boundaries with Nanuk

Audi developed the Nanuk Quattro concept show car in collaboration with the designers from Italdesign Giugiaro.
Displayed earlier this year at the 2013 Frankfurt Auto Show in Germany, the sports car was built for any stage of life and for any surface – equally at home on the race track, the highway or a winding country road as it is off-road in the sand or in the snow.

Its crossover concept combines the dynamics of a mid-engine sports car with the versatility of a sporty recreational vehicle.

The two-seater is powered by a newly developed V10 TDI installed longitudinally in front of the rear axle.

The powerful 5.0L diesel engine produces more than 544 hp and delivers 737.56 lb-ft of torque to the crankshaft from just 1,500 rpm.

121298reportcar_00000070677Its twin-turbo register charging unit is controlled via the Audi valvelift system (AVS).

121298reportcar_00000070679The common rail system operates at an injection pressure of 2,500 bar. A beefed-up seven-speed S-tronic, located behind the engine, transfers the torque to a specially designed quattro drivetrain.

The Audi Nanuk Quattro concept has a curb weight of around 4,188 lbs, yet is able to sprint from 0 to 62 mph in 3.8 seconds with a top speed of 189 mph.

The innovative thermal management with its separate cooling loops and the steplessly regulated oil pump contribute to the excellent fuel consumption of about 30.16 mpg on average.

Double wishbones guide the show car’s 22-inch wheels, which are shod with 235/50-series tires up front and 295/45 at the rear. The carbon fiber, ceramic brake discs can withstand high temperatures and are extremely abrasion-resistant.

The adaptive air suspension with electronically controlled dampers features the next generation of technology from Audi.

The driver can manually adjust the ground clearance of the Audi Nanuk Quattro concept in three stages: normal, 1.18-in. lower or 1.57-in. higher.

The system also controls the level of the body itself based on driving speed and the predictive route data supplied by the navigation system.

On the highway, for example, the body remains lowered even when the Audi Nanuk Quattro concept is moving slowly. It is automatically raised when turning onto a gravel road.

121298reportcar_00000070681Another technological highlight of the show car is the integral steering, which resolves the classic conflict between dynamic handling and stability.

The system combines the proven Audi dynamic steering at the front axle, which among other things can intervene at the cornering limit for enhanced stability, with supplemental steering for the rear wheels. Separate actuators activate the two active track rods.

Although plans to build the Nanuk Quattro for the general ­public is undecided, consumer excitement for such a performance vehicle could steer Audi executives in the right direction.

When I started driving way back in 1977, it seemed like you had to buy a truck to get a 4WD vehicle. Actually, the first 4WD car was built a long time ago in 1903 by the Spijker brothers. The first commonly produced 4WD car was built by Subaru around 1974, with the AMC ­Eagle and Audi Quattro joining the party around 1980. Volvo came out with its all-wheel drive (AWD) ­vehicle in 1997. It worked pretty well, but if you didn’t ­rotate your tires and ­decided to ­install just two new tires, the size ­difference between the new tires and old tires was enough to chew up the differential. It was recommended that if you had a tire ­problem and needed just one tire, that you ­replace them all.
