Audi R8 Supercar Takes Advantage with AdBlue

What can only be described as probably the most fascinating car Audi has ever produced, the Audi R8 is the distilled epitome of over 70 years of motorsport innovation.

Traditionally, the R8 uses same 4.2 litre V8 petrol engine as found in the RS4, however a new version has been produced which takes advantage of modern diesel technology.

The diesel engine itself isn't entirely new. It's a six-litre V12 which is already scheduled for production in a future version of the Q7. Naturally, the R8 is a lot lighter and sportier than the Q7 so in this frame, the engine delivers a massive 493bhp of power compared to the (16% less) 414bhp of the V8 petrol.

As to be expected, the diesel R8 uses quite a lot of fuel, however in order to conform with proposed Euro 6 limits it relies on AdBlue technology to reduce emissions.

When the two models are compared in the table below, you can see exactly how the diesel/adblue version performs in comparison to it’s petrol fuelled sibling.

Fuel:	Petrol	Diesel
Engine:	4.2 V8	6.0 V12
BHP:	414bhp	493bhp
Top Speed:	limited to 187 m.p.h. on both
0-62mph:	4.6 seconds	4.2 seconds
Torque:	317 lb/ft	737 lb/ft

With combined diesel and adblue technology making this possible with one of the most revered sports cars to date, who knows what could be achieved using the same technology on other performance cars in the future
