Audi's head of development Ulrich Hackenberg stated, “In the future we will need turbocharged engines for the R8, to meet the needs of certain market around the world. There are some other numbers between four and eight cylinder.” Essentially, he confirmed the next generation turbocharged V6 and that the R8 will get this motor at some point.
Additionally, the R8 will not longer offer a manual transmission option. Like the Lamborghini Huracan on which it is based, a 7-speed dual clutch will be standard and the only option. Expect more and more manufacturers to go this route as it appears the manual transmissions days are numbered.
With a dual clutch transmission, lighter weight, and a turbo V6 power the entry level R8 will become a very interesting performance option in relation to the V10 big brother. A simple ECU tune might put it on par with the V10 and Audi no doubt is aware of this.
