Shock new Audi concept unveiled at Frankfurt
It is powered by a mid-mounted 5.0-litre V10 turbodiesel engine, which develops 544bhp and a towering 998NM of torque.
With such a surfeit of grunt on offer, the Nanuk's claimed performance figures are astonishing. The 0-62mph sprint is dealt with in just 3.8 seconds, with the car powering on to a 189mph top speed.
Despite this, Audi claims this might powerplant will return an average of 36.2mpg.
Being an Audi, the Nanuk is fitted with the company's Quattro four-wheel-drive system, with power being channeled through a modified version of the current seven-speed twin-clutch S Tronic gearbox.
Four-wheel steering also features. Operating in the opposite direction to the front wheels at low speeds, and in the same direction as speed rises, the system aids both manoeuvrability and stability.
The Nanuk is a joint collaboration between Audi and design house Italdesign Giugiaro, and fuses traditional Audi design details, such as the trapezoidal grille, with Italian styling hallmarks for an aesthetic unlike anything we've seen from the German marque.
This is not the first time Audi has released a concept car designed to be filled at the black pump. In 2008 it created the stunning – and fully working – R8 V12 TDI Le Mans Concept, which at the time was to make it into limited run production. The project was eventually shelved due to a lack of profitability.
What do you think of the Audi Nanuk concept? Can a diesel supercar work, or does extreme performance now lie in the new wave of electric hybrid supercars? Have your say below.
