Audi just unveiled the 2014 RS7 Sportback on the floor of the 2013 Detroit Auto Show with a staggering set of performance specifications.

For starters, the 560 hp and 553 lb-ft of torque available at 1,750 rpm thanks to its twin-turbo 4.0-liter V8. That’s enough to push the car from 0-60 in less than four seconds. It’ll hit 100 km/h in 3.9, which is the same as 62 mph, but Audi didn’t mention how quickly the car reaches the all-important U.S. benchmark speed.

Apart from that, it’s also about 55 pounds lighter than the S7 and is limited to a 155-mph top speed. According to Audi, all that performance is possible while achieving an average 24 mpg. Of course anyone who’s driven an Audi S vehicle will likely tell you the same thing – that the mileage estimates count for bupkis.

Then again, that might not be the case here because Audi’s V8 uses cylinder deactivation to run as a four-cylinder when its full force isn’t required. That will be helped further by the fact that the car features an especially tall eight gear for highway cruising.

As you can probably guess, that means the car comes with a standard eight-speed automatic transmission.

Aside from mechanical performance numbers, the car comes with 20-inch alloy wheels with the option for three additional alternatives – all with a 21-inch diameter. There are also vented disc brakes all around with black brake calipers painted with the RS5 logo.

And RS car wouldn’t be an RS car without loads of extra accents and body modifications, and this is no different here. Loads of carbon fiber trim pieces set the car off including a big carbon fiber bar in the bottom of the grille with the Quattro name embossed.

It’s the same story in the cabin, where the cabin is virtually coated in carbon fiber inserts.
