I thought it was worth mentioning one of the most exciting concepts that were presented at the Detroit Auto Show: Audi R8 V12 TDI. This new concept from Audi is absolutely gorgeous and if it will make its way to the U.S then the car will be a great success among the Audi fans and not only.

The R8 V12 TDI uses the 6.0L V-12 diesel from last years Q7 concept with the award winning R8 sports car. The concept engine shares a cylinder count with the race-winning R10, but it's actually a completely new engine with a 60-degree bank angle instead of the 90 degrees used on the race engine.

It outputs 500 hp and it has 738 lb-ft of torque. While the R8 V12 TDI goes to 62mph in 4.2 seconds and it's limited at 186mph, it also manages to get 23 MPG, which is pretty good, considering the facts.

The combination of a 29,000-psi direct-inject fuel injection system, particulate filters and urea injection allows this beast to pass 2014 EuroVI emissions standards, so Audi is all set for the next few years.

If you're asking me, a BMW fan, I would probably buy one, unless the final price will be in the Ferarri range.

P.S That moonroof is amazing!!!!
