I am pretty sure I've read a thread over here with v8 460hp twin turbo

 

I agree with those who say its a bit tame. But at the same time its just enough. I like it and think its going to look great once we get some real life pics. Im hoping for an FI motor but im sure it wont be. Anywhere from 450-470 seems more realistic. Its a shame that i dont like any of the wheel options that are in that brochure.

 

Guys, it's a NA FSI V8, a tweaked version of the RS4's motor-no forced induction, rated at 450bhp. And for the first year of production, the only tranny is the S-tronic, no 6-speed manual option. Not sure about tranny options for next year and not sure if it's even ever coming to North America.

 

I think Audi will go the Nissan GT-R route S-Tronic only.

 

Audi RS5 Leaked - High Res Photos

"Speculation over which powerplant will drive the RS 5 has ranged from a massaged 3.0-liter supercharged V6 in the S4, 4.2-liter V8 and 5.0-liter V10 in the RS 6 to the range topping 5.2-liter V10 from the R8. Horsepower has been logically guestimated between 450 PS (331 kW / 444 hp) and 550 PS (405 kW / 542 hp), essentially where the RS 4 leaves off with 420 PS (309 kW / 414 hp) and ending with the RS 6 and its 579 PS (426 kW / 571 hp)."

 

Like it alot! I wouldn't mind if they'd gone wilder, but this is very nice. I'll have mine in anthracite, please.

 

I suspect (unfortunately) you are correct.

 

This is speculation from two years ago. Next week the press embargo will be lifted and the NA 4.2L FSI V8 with intakes modified from the RS4 will be confirmed making 450bhp, and probably not much more torque than on the RS4.

 

I love it.
Now MB will change their mind about not making an AMG version of the E-class Coupe.

 

GT3 in Australia is another step up from a used R8 or new RS5 price.

FYI we pay:

New S5 $160k
New RS5 $200k + (Estimate)
Used R8 $190-230k
Used GT3 $260k
