The new Porsche 911 GT3 engine revs to 9,000 RPM. The 4.0L boxer six-cylinder is naturally aspirated, producing 502 horsepower and 346 lb-ft of torque. The engine is packed with clever features including individual throttle bodies, two resonance valves, rigid valve train, DLC-coated rocker arms, large-bore cylinders, and a dry sump oil system with seven pickup locations, ensuring proper oil flow under track conditions. The 4.0L has seen numerous updates since its introduction in the 2011 GT3 RS 4.0, and has been used in subsequent 911 GT3 variants since.
The 2022 GT3 has also lapped the Nurburgring in just under seven minutes! Thanks to weight reduction through material selection such as carbon fiber reinforced plastic, titanium engine components, and special glass, the curb weight is kept low. Handling is improved with a new front and rear suspension, completely redesigned from the standard 911. Grip is maximized with Michelin Cup 2 R tires, and significantly increased downforce over the previous GT3.

As you grow older you just appreciate 911's design more and more.
-
The GT3 has been making 500hp since the 997 era and it’s still getting faster. Porsche engineering really understands it doesn’t just take horsepower to go fast, well done!
-
So Porsche optimized their engine by allowing wifi signals in, got it.
-
As a child I would listen to my father go on about Porsche engineering. Now in my 50's, I do the same to my kids. I hope the tradition keeps on. This video jogged my memory back. Thank you.
-
I absolutely love the fact that I can learn so much for free
-
The engineers at Porsche truly left no stone unturned in the search for more horsepower without forced induction. They even changed the yellow for red brake calipers!
-
As someone who‘s been studying both music and engineering (although the latter for a much shorter time), I must say I get the same chill down the spine when seeing this kind of genius work as I get when listening to Bach. It’s truly inspiring.
-
These are some of the things that make Porsche so damn incredible, they always go the extra mile on literally everything. They are just geniuses.
-
Holy crap. The engineering of that intake manifold and valve timing is insane.
-
I wanna see a Porsche engine with Koenigsegg's free valve tech. That would be black magic!
-
Love Porche's dedication to maximizing the existing fundamentals rather than moving to bigger displacement. Great explanation to simplify the "magic" at work.
-
Porsche will never surrender their iconic ICE engine for electric. Been polishing this diamond for over 50 years. They're all in.
-
I work nights. I'm a nurse. I love cars. You just earned the" No way are you a loser award"! You held my sleepy attention, for 13 min and 17secs! I applaud you.
-
Porsche: THROTTLE ALL THE THINGS!
-
Just buy any naturally aspirated 911. Almost 7 years with mine and absolutely no regrets. Still need another S2000 though. 🤤
-
Me: absolutely clueless about everything you said Also me: Wow that's very impressive.
-
"designed to last the life of an engine." Nothing good ever came with this sentence!
-
I never knew about the pressure waves in the intake, and the engineers at Porsche are geniuses for getting all the the timing correct to utilize them, not to mention the software engineering required to get all those throttle bodies to work in sync. That's incredible engineering.
-
Solid lifters that never need adjusting is spectacular. That would be an improvement to basically every performance engine from any manufacturer.
-
German engineering at its best. And I love the fact that they listend to the Fans and offered a Manual again as well as making the Car N/A.
