Spy Shots: Audi TT-RS and RS5 caught testing

A pair of Audi RS performance cars have been caught testing and show what the German brand has planned for these ultimate examples of the TT and A5. The TT-RS was snapped in production ready form and shows off some serious design tweaks including two gaping intakes flanking the already gaping corporate Audi grille, chunky fender flares at all four corners and a pair of large oval exhaust tips embedded in the rear bumper. Powering the TT-RS is expected to be a twin-turbo 2.5L five-cylinder engine producing between 350 and 390 horsepower, which will easily make it the fastest production TT ever.

The next car is the RS5, and less is known about this model since it was snapped wearing the guise of an S5. Caught on the Nurburgring in Germany, this RS5 mule is wearing an RS-inspired front end, but confuses the camera lens with its lacked of flared fenders and quad exhaust tips where one would expect an RS model's typical dual ovals. Still, there wouldn't be much of a reason for Audi to test the current S5 on the 'Ring, so what we're looking at must be an RS5 mule. What will power the RS5 is still speculation and could be either the 4.2L V8 from the RS4, a twin-turbo V8 or the Gallardo-based V10 from the RS6.

Audi has done a great job with the S5. It just looks really good, so it can only look better as it transforms into an RS5.
I would go with the tt V8

Agreed. Looks really good.

I agree. I absolutely love the S5. I'd go with the blown V8 for the RS5 too, although V10s just sound so cool.

If its the TT V10, we need not worry about seeing it in the US. That engine wouldn't pass emissions in the RS6.
With BMW going TT V8 in the M5 and possibly other cars, I wonder if Audi won't do the same eventually.

I doubt that the RS5 will have a V10. I'd imagine it will be powered by a V8 of some sort with at least 450hp.

Yup, everyone talking to people at audi (CAR, EVO, etc) is hearing Twin Turbo V8 right now.

Twin turbos on a 5-cylinder? Not likely.

A staged turbo setup with a smaller and a bigger unit or a combination of supercharger/turbocharger is quite possible.

perhaps they mean sequential turbos?

is it just me or does the bit underneath the headlights on the tt look too much like a lambo. same with the rs5

Definitely some hints of the LP560-4. Not complaining though!

they both look like they will be fast cars. The RS5 should be interesting with Audi switching to superchargers, maybe they will keep the S5 motor with a supercharger on it. There are already aftermarket kits for the S5 that have superchargers that are hitting 500 hp, so should be fun.

Am I the only one to think that Audi needs serious motor rationalization these days? It seems like they have new motors - and variants of those motors - for every new model. Its amazing that they can get them all certified for US/EU emissions. Don't get me wrong, they're all impressive but why not standardize a little?

Since Audi increased the piston diameter from 84.5 to 85.5 in their V6, that could be applied to the V8, 4.2 to 4.3 liters.
So an increase from 414hp to 425hp, and an increase of torque from 317 to 325ft-lbs.
and maybe more power with Audi Valvelift 450hp?
A 5.3 liter 500hp audi Valvelift V10 would be nicer though.

(Thumbs up) to the RS5 - I want!
With the Quattro Sport Rear Differential and Audi Drive Select, this car will handle spectacularly. It's great to see Audi coming out with such dynamic vehicles these days!

Okay... So I understand that brenda priddy and co might know more being on-the-scene and all... but Honestly? This looks like a stock S5 with an ugly grille and after-market lower valance. There are no signs that this is a company owned mule (plates are civilian, and no other markings... anywhere).
Lastly... the RS5 would have a wider track, no?.. because this one obviously doesn't
I'm just sayin... Ya'll (C/D, M/T, Wertopnik, et al.) need to think more about the dynamics before putting up a post.
