The New Porsche 911 GT3's Engine Is A Masterpiece
The 2022 Porsche 911 GT3's 4.0L Naturally Aspirated Boxer Six-Cylinder Engine

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.

    if Porsche could get a more aggressive look like Mclaren , ferrari etc and having more nicer color options varieties and increasing their PS not in 10 or 20s but like 50-100ps more...that I would be happy

    Why is it you see Porsche and other flat plane engine in Europe run twin throttle bodies vs one. Would that same concept help cross plane v8 setups? And often the dual TB also have their own plenums. So someone fill me in please. I’m building a monster rather then buying one.

    Not that I can afford it but if I could, the GT3 would be my dream machine. Yes the GT2 is faster etc but the GT3's high-revving natural engine and physics defying handling make it the ultimate driver's car.

    Porsche was clever to use a naturally aspirated engine and avoid turbos because of turbo lag, Porsche decided to use multiple throttle bodies than just one for atmospheric pressure to get into the cylinders and for more power. Subaru started using boxer engines but Porsche took the advantage over Subaru and now Porsche is known as making the most powerful boxer engines. The 911 can beat a lambo and a dodge demon. Good job Porsche 👍🏼

    Nothing wrong with daily driving an electric car. I absolutely love my Tesla Model S. Best purchase I've ever made, and I'm a diehard gearhead. I drive from Western Colorado to Indiana every May for the Indy 500, drove to Milwaukee 2 weeks ago for a vintage IndyCar race, and in just over a week I'll be headed out to Bonneville for Speed Week. Oh, and all those trips every year cost me nothing in gas. Also, as a side note, if you haven't been to Bonneville for speed week, you should check it out sometime. Lots of really unique engineering out there. Some successful, some not, but everyone is always trying something new to try and conform to one class or another.

    I have a 4.0 liter 997 911 and keep telling myself to sell it because in Atlanta the roads are terrible and the traffic is horrific and who couldn't use another $50-60k. I just can't. Some inexplicable force has controlled my brain and I am physically unable to list it.

  • Spinnetti

    As a car? AMAZING. As an object of dreams? not so much. my 13 year old R8 at the same displacement is only 50hp down, cost about 1/3 the price (used), a manual and is much finer to look at while still an amazing drive - Oh, and its fine looking engine is under glass, not invisible. I'll keep the R8, but appreciate the 911 from afar without regret ;)

  • Magnus Danielsson

    You could argue (David Vizard does) that there is a fifth cycle in a four stroke thats very important. Thats the overlap period of the intake and exhaust valves. With a properly tuned exhaust you achieve alot of cylinder fill with the suction of the exhaust going out. You can even have too much of this if the exhaust is too efficient for the engine.

  • Duane Samuelson
    Duane Samuelson

    Going back to the 1950's Chrysler used intake tuning to dynamic supercharge...they also tuned the exhaust to scavenge at the same RPM. Unlike the porche it was only tuned for a single RPM with fall off as you moved outside the band. What I'm more curious about how, with a larger bore, they handle ring resonance so the cylinder wall isn't chewed apart.

    What a waste of time and energy! This is analogous to a stagecoach manufacturer ignoring the writing on the wall after the advent of mass produced ICE vehicles. Instead of the stagecoach manufacturer focusing all its resources on the transition from stagecoaches to ICE technology it instead decides to ‘perfect’ the stagecoach. Engineering Explained is a very interesting channel but after watching this video and the one where it tried so hard to make a Toyota RAV4 hybrid seem equivalent to a Tesla Model Y (which it is not even close)I have to wonder what’s motivating the channel. Porsche would have been better off if it had spent the money it wasted perfecting this ICE engine on technology to improve the dismal range of the Taycan. All these folks commenting on how impressive this engine is are missing the point. Sure, I can appreciate a magnificently engineered stagecoach but in 2021 do we really need it?

    • Olasek

    With engineering like this, I really do hope the internal combustion engine still lives on beyond the UK Government's proposed 2030 ban. With the technology we have, I am sure going full electric isn't necessary. I hate EVs and as for the Taycan, quick it may be but it is boring as hell. I see engines as a work of art. I am going to be so heart broken when everything, including motorbikes becomes electric. I'll just give up on my passion and that is motorcycles.

    Horsepower per liter is the least important metric when thinking about performance, exterior dimensions/weight are far more important in the real world. Looking at engine weight alone a 4.0 Porsche engine weighs the same as a 7.0 LS7 from the Z06 with around the same HP level but almost 150 lbs of torque less. I know the old argument that yeah the Chevy has to be twice as big to make that power but I argue that other engines need twice the valves and 2K more revs to match the power output of the LS engine family. These engines are all masterpieces that just take different routes to meet a need. I'm not sure how the new Porsche drives but the ones I've driven have been fairly peeky in power output vs. a big V8 that has torque everywhere.

    Please do one on thr Buick 3.8L V6! It placed in Wards top ten best engines in the world for at least 3 years of its production if I remember right and the early early variants were basically just a V8 that they took an oxy/fuel torch to. They sound incredibly unique and were even used in Indy races for a while (relatively average performances, no titles, but still). Would love to know more about it and it's development.

    Manipulating pressure waves is how expansion chamber exhausts work on two stroke engines. This is what enables two stroke engines to makes so much power per cc.

    The reason for valve adjustments is to compensate for valve seat wear; which causes the valve to sit higher in the cylinder head. Not because the rocker arm wears.

    Not to take anything away from Porsche but Variable intake manifolds have been done for years. Same with boosting na engines without a super/turbocharger. This technology has been done in ww2 aeroplanes! Another thing manufacturers do is reduce the width of main and big end bearings which obviously help with frictional losses. This is especially true with boxer engines! BMW also did this on the s54 but they suffered from premature bearing wear. I am impressed with the diamond coating though. I am also very impressed that Porsche are able to make this power reliably! That’s incredible!

    Jason should make a video on why only Porsche can do a 6000 rpm clutch dump when launching their car and do it all day long while no one else has even tried to match the PDK. Rear weight balance or superb Launch control, nothing launches like a Porsche. Why?
