Rumour: Porsche Working on 997.5 Turbo S To Finally Take On The GT-R

Things are really beginning to heat up at Stuttgart. Not only is Porsche caught in the middle of a take over by Volkswagen AG, it’s also churning out new models almost every other week. Hot off the introduction of the GT3RS,  rumours are rife of a new Porsche 997 Turbo S; a continuation to the 993 Turbo S and the 996 Turbo S. Why it took Porsche so long to reveal an S model is debatable but the accepted theory is that Porsche wanted to avoid the Turbo S stepping on the toes of the GT2, considering that the latter only makes 40 horses more than the plain ol’ Turbo.

Lets consider a few details, 520hp is already on the limits of the performance-to-reliability ratio that OEMs have to think about and that’s the number the current 997 GT2 puts out. But that’s from the old 3.6-liter powerplant, so if Porsche was able to scrape that much power from a 3.6-liter, then more can be done with the new 3.8-liter engine – that’s expected to debut in the new 997 Turbo – without compromising on reliability.

So, according to our sources, a new 997.5 Turbo S is coming, and soon, somewhere mid-next year soon. Power is speculated to stand at 540hp to 550hp, and standard accessories include ceramic brakes, RS-style center lock wheels, and some sort of unique bodywork to differentiate it from mere Turbos. This is purely speculation and could ultimately prove to be false, but if it does materialize then expect the Turbo S to finally fend off the GT-R menace on it’s home turf, the Nurburgring. Then expect an even more hardcore 997.5 GT2 rocking on the same 3.8-liter powerplant boasting even more power than mere 550hp.

I think reliability issues for the engine unit itself is not a problem. They can churn out 600bhp from the 3.6L unit if they wanted. They just need to use stronger parts, either new materials or better fabrication techniques, which all translates to cost, to achieve the desired reliability targets.

The hp game is simply market driven.

More difficult would be providing adequate cooling which affects bodywork design etc

I quote myself:

"The hp game is simply market driven"

The engineers do not decide what hp is 'right' for the market. They engineer what management tells them to engineer.

you are probably right, after all so many german tuners like Gemballa, Ruf, TechArt, 9ff have been tuning 600+hp 911 turbos since years ago.
