That thing looks great. My personal spec would include an NA Flat-8 revving to over 9k, manual gearbox option, weight under 3k pounds, and hydraulic steering (pump electrically driven like all racing 911's).

Modern 908 road version? It could be a tough choice between that and a proper powerful and stripped analog 911. I'd probably go with whichever's smaller, assuming I had budget.

That would be a mean machine.
I agree with all the other posters that not much will be known until FIA/WEC/ACO finish their GTE regs. I would bet on some sort of 5 liter NA, 4 liter turbo, and some combo of hybrid powerplant that mimics LMP1 regs.

They can keep the turbos. The 488 might have the best street turbo engine yet, but I think EVO's new review says it well:

This is what I've read.

"scuttlebutt is that Porsche’s leaning toward a flat-eight for the new car. The UK’s Autocar reports that it may feature a turbocharger for every two cylinders, in the interest of minimal lag and maximum complexity."

Maximum complexity is great right up until you take your 918 Spyder in for repairs after the warranty has run out.
Unless those upcoming racing rules require it, I'd hate to see Porsche have to develop an all new engine when they already have the 918's stellar V8.

Will Porsche ever consider cylinder deactivation? In lieu of turbos or superchargers?
The base Vette C7 and Bentley Continental Coupe V12 both have it as a way of increasing MPG and reducing CO2.
Just curious.

I suspect you run into additional issues with cylinder deactivation on a flat six, and turbocharging is likely a simpler and cheaper alternative. I would expect this next generation of engines to be an interim step, however. Given that more efficiency means more performance I think we'll see another step forwards not long after. The fact that the turbo engines are rumored to be based on the 9A1, already fairly old and not easy to modify for some of these technologies, suggests to me that perhaps they have something else cooking. Only speculation on my part, however.

They have certainly played with it and even have some patents in the area. Also variable compression, which one could combine with variable cam technology to do a very effective Atkinson cycle (what the Prius engine uses).

I believe that the separation of this new class (GTP) with GT3 is why Porsche decided to develop the GT3R with the 9a1 engine. We will be seeing the 960 with a v8 turbo.

The new technical regulations have been announced at this year's Le Mans race. GT will become GTP and will place the performance above the FIA GT3 cars. The new Ford GT (and I would presume, the new Ferrari 488) adheres to the new technical regulations. We will be seeing turbos and big rear diffusors.

Yep - that would be extreme. Part of the issue is that I'm not sure you can exploit the benefits of a rear diffusor on a rear engine 911.
It's also interesting that program director for the 918 was Frank-Steffen Walliser. He is now the GT Motorsport Director.
