The 2013 Frankfurt Motor Show is the gift that just keeps on giving. Audi has gotten in on the action with the reveal of the Audi Nanuk Quattro ($TBA). The Nanuk is a high performance diesel coupe. It boasts a 537bhp 5.0-litre V10 TDI engine and can get its almost 2,000 pounds to 60 mph in under 3.8 seconds with a top speed of 190mph. Many of the features look like they could easily translate into the the next generation R8. Check out more pictures after the break.
