Most believe that since Audi has stated that they will only release one RS model at a time, the Audi will be launching the RS5 in 2010 as a 2011 model. The new RS5 is set to debut at the 2009 Detroit Audo show. There is however some talk about the release of the RS5 being sooner. At this point there is no confirmation from Audi in either direction. Although much of the buzz surrounding the RS5 is speculation at this point, he general concensus is that the Audi RS5 will carry a 4.2 liter V8 engine complete with two small but highly responsive turbochargers to produce 450-480 horsepower giving it the ability to go from 0-60 mph in 4.5 seconds with a top speed of 155 mph. The torque expectations are high, at or above 500lb ft torque. Another option which has been highly publicized in blogs across the internet is the possibility for the RS5 to get the Lamborghini V10, similar to the one in the S8.The car will be developed by Quattro (Audis in house team of engineers) on the A5 chassis and will get the same carbon ceramic brakes found in the R8, 19 inch allow wheels and modified magnetic ride dampers taken from the TT. Pricing is expected to be around BMW M3’s £50,625.

• Speculated Horsepower - 450 - 480
