Audi debuted the turbodiesel version of its flagship A8 sedan at last year’s Los Angeles Auto Show. At the time, we were told that pricing and fuel economy details were pending, and now the four-ring brand has published the data ahead of the car’s launch.

The diesel-powered luxury sedan will be available in a long-wheelbase version only, priced from $83,395 including a destination charge of $895. It’s 3.0-liter TDI engine is rated at 240 horsepower and 406 pound-feet of torque, which is enough to get the full-size sedan from 0-60 mph in just 6.4 seconds.

The EPA say you can expect fuel economy of 28 mpg combined, with 24 mpg in the city and 36 mpg on the highway. That’s quite a bit better than other long-wheelbase A8 models, as even the turbocharged 3.0-liter six-cylinder gasoline version returns just 21 combined, 18 city and 28 highway.

The diesel model’s pricing puts it mid-pack as well, above the turbocharged 3.0-liter V-6 gasoline L model (by $4,000), but below the turbocharged 4.0-liter V-8 gasoline L model (by $4,700).

The 2014 A8 L TDI becomes the sixth model in the Audi A8 family, joining the A8 3.0T, the A8 L 3.0T, the A8 4.0T, the A8 L 4.0T and the A8 L W12. Look for the TDI models to begin hitting Audi dealers in the spring.
