2011 Audi A8 Unveiled in Miami

Audi has officially unveiled the all-new 2011 A8 at Miami's Design Week.

The 2011 Audi A8 gets all-new styling that draws cues from many of its other siblings in the Audi lineup. It features Audi's first application of full led headlights that can adjust their lighting direction based on the navigation system.

"The new Audi A8 is the sportiest sedan in its segment," says Rupert Stadler, Chairman of the Board of Management of AUDI AG. "It combines numerous functions in a new and intelligent way. And it's unmatched in the stylistic elements and impression of the interior."

Audi claims that the 2011 A8 is longer and wider than its competitors and it also sits lower.

The new A8, which arrives in US dealerships in late 2010, is powered by a 4.2 FSI V8 that puts out 372 horsepower and is now 15 percent more fuel efficient. The V8 is mated to an eight-speed automatic transmission.
