2010 Audi RS5 to get 4.2L V8 from RS4, Cabriolet RS5 in the works

The next-generation Audi RS4 is rumored to be get the same supercharged 3.0 TFSI V6 from the 2010 S4 but will be messed around with a bit to produce 400-hp. So what happens to that beefy naturally aspirated 4.2L V8?

According to CAR, that engine will find its way under the hood of the upcoming Audi RS5 and will be twin-turbocharged to produce a total 450-hp with a peak torque of 332 lb-ft. That will allow a 0 to 62 time in the low 4.-something seconds.

The UK publication says that Audi is also planning a cabriolet (convertible) version that will join the RS5 coupe, which will hit showrooms in late 2009. The RS5 Cabriolet will be a soft-top convertible.
