So the boys over at Audiworld have confirmed that Audi will indeed return to its B6 roots and twin-turbo the upcoming B8 S4.

Here is an excerpt from the article:

We have confirmed with inside sources that the B8 S4 will debut with a brand new 3.0-liter TFSI bi-turbo producing 330-hp. With this powerplant Audi can nearly match the B7's 340-hp output while providing even better performance figures. Manufacturer published (conservative) 0-60mph drops from 5.4 seconds to very low 5's, while the accompanying combined fuel economy rises from 17 mpg to over 20 mpg.

With a manufacturer estimated 0-60 time in the low 5 second range instead of the current 5.4 seconds, the B8 S4 should be squarely within range of the BMW 335i which features its own twin-turbo powerplant producing 300 horsepower and 300 lb./ft of torque.

It will be interesting to see what Audi does with the B8 RS4 given that the B8 S4 will feature 340 horsepower. The current 420 horsepower B8 will not provide nearly enough performance advantages over the S4, so it is probably safe to say, Audi will be increasing the horsepower output tremendously of the B8 RS4.
