Very well could be; first time ever that Porsche has fitted an engine bigger than 4.0L in a 911.

Side exhaust and big diffuser would be interesting on the road version...

Seeing the shape of the swan neck gives me hope for the 992 GT3... I hope it's this beautiful and delicate in design.

Guess that takes care of all the naysayers that said Porsche couldn't/wouldn't build a 4.2L flat six.....

Nice, simple livery. Here's hoping it runs as good as it looks (and better than it sounds!)

Wow!

Will be be interesting to see if the 992 RS gets a similar engine

Maybe I will have a reason to upgrade to a 994 GT3!

So, they kept the same stroke as the 4.0L but increased the bore. This means we should keep our high 9k redline. The 3.8L became a 4.0L with more stroke - this time we can keep the crankshaft and rod length and change just the pistons (maybe even more compression to go with new injectors seen in the Speedster). 200cc only implies 5% more power and torque, but a bit more compression and better breathing (ITB's) could bump that slightly.

I think ~530ps and 365 ft-lbs would be possible in GT3 (and >545ps for GT3 RS).

I'll take the extra horsepower and torque, but the new RSR does not sound as good. In testing and in the video. Hopefully that changes.
