Not only will the new model sport two more cylinders, but it will also feature new front and rear bumpers and a revised exhaust system.
It remains unclear what Audi will call the new model, but Autocar reports that the RS8 nameplate is likely, leaving the RS version of the A8 in limbo. However, R10 still remains a possibility.
The 4.2L V8-powered R8 makes 420 horsepower, and it is expected that the new V10 engine will bump the R8's rating to at least 500 horsepower. The V10-powered Audi R8 is expected to bow in September with an on sale date of early to mid 2009.
