Audi will offer an A8 diesel sedan later this year, the company announced at the North American International Motor Show in Detroit.  The Ingoldstadt-based automaker also announced a supercharged V-6 petrol model, the A8 3.0T.

The 2013 Audi A8 TDI will come with the turbocharged 3.0-liter V-6 that develops 225 hp and 406 pound-feet of torque in the Audi Q7.

The A8 will become the second full-sized luxury sedan available in the U.S., alongside the Mercedes-Benz S350 BlueTec, and leaves BMW as the only premium German automaker without a full-sized diesel sedan.

The A8 diesel will have similar standard and optional equipment to the current V-8 powered A8 4.2, which starts at $78,750.  The Mercedes-Benz S350 BlueTec starts at $92,550.

EPA fuel economy for the S-Klasse is 20 mpg (11.76 l/100 km) in the city and 31 mpg (7.58 l/100 km) on the highway.

It will be interesting to see what the EPA rating for the Audi A8 TDI will be. In the EU cycle, the Mercedes-Benz S350 BlueTec sold in Germany used 10.1 l/100 km (23.28 mpg) in the city and 5.9 l/100 km (39.86 mpg) on the highway.  The German Audi A8 TDI used 7.4 l/100 km (31.78 mpg) in the city and 6.0 l/100 km (39.2 mpg) on the highway. While the two cars are comparable in highway fuel economy, the Audi used roughly 25% less fuel in town.

Start-stop technology will be standard on the new Audi diesel and it will be available with the optional Audi connect infotainment system which incorporates Google Earth maps and real-time SiriusXM traffic information, localized weather, news, real-time fuel prices, Google Local Search, support for Google Send to Car via the myAudi Destination feature, and an in-vehicle hotspot that supports up to eight Wi-Fi devices.
