Unfortunately, the Audi Nanuk Quattro Concept ($TBA) is just one of those things that's too good to be true — too strange and too exciting to ever make it into production — but that shouldn't stop you drooling over it. A sort of supercar crossover, this Audi boasts a twin-turbocharged V-10 diesel TDI engine that outputs 544 horsepower and a staggering 738 pound-feet of torque. All that muscle coupled with a special variant of their Quattro all-wheel drive system and adjustable ground clearance would make this car fairly capable on even the roughest roads. As if that wasn't enough, it gets 30 miles to the gallon, and features integral steering (the rear wheels turn slightly in the opposite direction of the front wheels, giving it better handling in turns). Here's hoping at least some of this tech sees the streets one day soon.
