Rumormill: Audi RS5 to get 4.2-liter V8 from RS4

The crew at Audi's quattro GmbH division remains hard at work. Now that the TT-RS is out in the open, the next assignment is the RS5. Given that the recently-introduced S4 features Audi's new, supercharged 3.0-liter V6, it might have been expected that the RS5 would get a higher output version of that engine. Another option might have been the 5.2-liter V10 that does service in the S6 and S8. Instead, it appears that a revised version of the 4.2-liter V8 from the last-generation RS4 will find its way into the coupe. In RS5 trim, the V8 is expected to crank out 450 hp with a choice of 6-speed manual or 7-speed S-Tronic gearboxes. In true Audi form, all the wheels will get driven all the time.

If the RS5 does indeed come to the party with a 450 hp V8 it may truly be a sign that the German horsepower wars are winding down. With CO2 limits coming to the EU, it was bound to happen sooner or later.
