Audi RS4, Audi RS5: Next generation featuring V8 biturbo 4.0T engine?

Audi RS4, Audi RS5

Interesting thoughts here by our friend George Achorn from Fourtitude about the engine inside the next-generation Audi RS4/Audi RS5. Make sure to read!

Rumor stories around the press during this time prior to the RS 5’s launch still suggested it might get the V10 biturbo from the RS 6. “It can’t be done,” said my source. “It simply wouldn’t fit.”

Normally well-connected and very in-the-know CAR Magazine held to the belief that the car would be some turbocharged V8.

Then, a few months later, my source told me about the 4.0T. This new V8 biturbo would be an interesting prospect. With everything nestled inside the V as seen on similar engines from BMW, I was told the engine (at this time still prior to the RS 5) would not go into the RS 5 but instead debut in the A8. Turns out the only official confirmation thus far about 4.0T is as a base engine for the Bentley Continental GT, though solid intel from multiple sources suggests it’ll also see duty in the A8, S8, S6, S7, RS 7 and, if there is one, an RS 6.
