A new report is indicating the 2012 Audi S8 will use a 4.0-liter twin-turbo V8 that produces 520 hp (388 kW / 527 PS).

With all the attention being focused on the Audi S6 and RS6, it's easy to forget the company is also preparing to launch a redesigned S8.

That stops today as a new report is indicating the model will use a Bentley-sourced 4.0-liter twin-turbo V8 that produces 520 hp (388 kW / 527 PS). If this is correct, the Audi would slot in between the 500 hp (373 kW / 507 PS) BMW B7 Alpina and the 537 hp (400 kW / 544 PS) Mercedes S63 AMG. Of course, weight and traction will play a factor, so it'll be interesting to see how the car compares when the official specifications are released.

Regardless, the Audi S8 is expected to be launched in the United States early next year.
