The 2023 McLaren Artura is packed with fascinating new technology. It features an all new 120º twin-turbo V6 engine, as well as an axial-flux motor, for a combined output of 671 horsepower and 530 lb-ft of torque. Keeping everything together is a new carbon fiber monocoque, with a 7.4 kWh battery pack. Power is sent through a new 8-speed dual clutch transmission, which also houses the first electronic limited slip differential in a road-going McLaren.

*Apologies all,* I know the audio isn't great on this one. At 1:48 the audio improves, and you get into the nerdy details/advantages of the axial flux motor. Sometimes I experiment with different audio setups - I tested this new mic setup at home and things went great, took it out for a shoot and it simply picks up way too much external noise (the interior is not as loud as this video makes it seem). I promise I'll learn from it, but I'll also probably make mistakes in the future - so it goes, appreciate you watching!! For some fun info, both Ferrari and Koenigsegg are also using this style of electric motor. Becoming more popular in the supercar segment! Mercedes also using it. Will be curious to see if the trend continues.

This is exactly the kind of plug-in hybrid turbo technology I've wanted! Throwing in the axial flux motor there makes it even that much better.

[@Blox117]

the magnetic flux can also flow from the north pole on one side to the south pole on the other rotor. this results in greater magnetic flux density around the stator since the magnetic field lines are being squeezed towards a parallel line between each magnetic pair that passes thru the stator.

[@EngineeringExplained]

Yep! Use it on both sides, and the rotors simply have opposite poles.

@@kevinburke6743 There's no such thing as "racial" flux, keep race out of this discussion, what you mean is something else.

In a promotional video, Fred Hunstable said, “We call it circumferential flux, sort of like a torque tunnel.” Hunstable coined his motor as circumferential flux motor.

[@MrZauberwuerfel]

As an electric motor designer, I have to say that I am impressed by your video. Some people make videos saying, that AF motors are better in every way, which is not true. However I want to clear up a few minor points: (AF = axial flux, RF = radial flux) McLaren says, its the first series production vehicle road vehicle using an AF motor. However the Ferrari SF90 Stradale also has an AF motor. Am I missing something here? Surely McLaren would know that. The more crucial point for this video are the advantages of the AF motor. Generally RF motors have higher power densities. For example the SF90 front (RF) motors have 99kW at 12kg (133hp at 26,5lbs). This is because they spin up to 25000 rpm. They don't need to have much torque to achieve that power due to the high speed. This AF motor has 70,1kW at 15,4 kg (94hp at 34lbs). So less power and more weight. The reason, why the AF motors are good at this application, is that they make good power at speeds of the ICE. In pure EVs you generally only care about power density (and field weakening range). Torque density does not really matter much, because you can multiply the torque with a gearbox. That's why pure EVs generally have RF motors.

[@riba2233]

Good post!

[@MassiveTrackHunter]

Getting 100hp out of something half the size of a torqueconverter, is AMAZING. Basically put two of those together in a transmission for 200hp, and run any small car without the weight and cubic feet space requirement of an actual engine bay! Imagine what engineers can do with the entire driveline being basically a transmission under the car and no engine bay at all, and still get several hundred horsepower out of it with 2-3 of these motors packed down there.

[@user-fo7mf9nd2h]

In terms of energy density and efficiency, radial flux motors, especially synchronous PMMs, are better at that job. That's why they are used in most automotive applications. For P2, of course, you gonna need an axial-flux motor (like Ferrari does for their SF90). P4 is always radial-flux though.

[@jameshancock]

The other huge reason for the density is that because they produce lots of power at low RPMs you don't need to have a transaxle with step down gearing. You can directly drive the wheels. That means doing a 4 motor drive train is easier and lighter. Which means that you can get to 400 HP trivially and eliminate complexity and weight. And you can stack them on the same axle, so doubling power is as easy as putting 2 motors per wheel instead of one and now you have 800 HP. I suspect Tesla and others are going to Axial Flux soon for this very reason. The best part is no part. Removing the transaxle with no other real downsides and with an easy scaling path, and 4 wheel independent control is a huge win. The only question to me is who's going to try putting these in the wheel as unsprung weight and get rid of the axles entirely. Would be an interesting experiment.

It'd be a hella overbuilt wheel hub of sorts.

Anecdote that no one will care about: When I was in high school (in the late 90’s), I was unaware of the Axial Flux motor, but I had learned about mag-lev trains. I imagined a motor with “mag-lev on the outside”, I wanted it to be more of a flywheel, so the stator was on the outside, with the magnets on the outer radius of the flywheel. I figured it could spin up to store energy and clutch out the power when needed… a few years later F1 started using KERS.

Love the video, I was already looking at such Axial Flux motors (sadly couldn't buy one) and I'm glad that you're covering this now. I wish the Audio was better tho :( Have you tried maybe a Wireless Mic? Like Rode Wireless Go or similar?

[@pierredelecto7069]

Those things would be sick for motorcycles. Mount it directly in the rear wheel hub then just mount a battery on the front in the frame.

[@primoroy]

For the first few minutes I thought this was a hub motor used on each wheel, I was excited. When I realized it's used behind an ICE my excitement dropped. It's still a fascinating vehicle and outstanding tech! 👏 😜

[@bearclaw5115]

Hub motors stink. Too much unsprung weight.

[@primoroy]

@@bearclaw5115 Yes, as sprung weight, but they can be inboard on short shafts.

[@MBergyman]

axial flux motors are so rad. Please continue making videos in a quieter environment. I appreciate that you get to drive around a sweet McLaren, but the background noise makes it harder to listen.

My 1983 antique boat has an axial flux motor. I might be the only person who upgraded a boat from radial flux to axial flux!

[@robertwicks174]

very interesting and entertaining Thank you. Would you please consider doing a presentation on the Omega 1 engine.?

[@judge831]

I'm looking forward to seeing this technology trickling down to affordable sports cars. Maybe we'll see a hybrid MR2 with the G16EGTS turbo 3 from Toyota mated to an axial flux motor for about 400 hp. Although personally I think 300 hp would be plenty if it stays under 3,000 lbs. Lightweight slow cars are always more fun than heavy fast cars.

Hey! I know that road...been a while since I've driven it though. For those that don't recognize it, It's the road that runs around Lake Mead.

[@prabhatgupta7170]

Love your videos 😍

[@FixingWithFriends]

Your new white boards sound very good!

[@NicuIrimia]

That bird at 14:40 is keeping up with the car!

[@TheOriginalBumper]

Cool video on the technology of axial motor used in this super car. Glad they could wedge this powerful motor between the engine and transmission. However, why on earth is there a starter motor on the engine. Makes no sense .

[@paulg3336]

The sections of windings outside of the stator are easier to cool than the ones inside - thinly coated copper in direct contact with the coolant medium as opposed to being enclosed in an iron channel but not in thermal contact with the channel wall

[@dukie1616]

Dang I subbed to this channel like 8 phones ago, now it’s pushing over 3mill subs, and it’s still thoroughly entertaining👏

[@EngineeringExplained]

Thanks for sticking around! :)

[@dairevickers]

@@EngineeringExplained any chance of putting mass in kilos in future videos? And N.m for torque as well would be nice for the majority of the world.

[@lee4171]

Astonishing vehicle. Nobody does it better. Great Britain.

[@rogerpullin8997]

Very impressed, good job, I hope the corvette engineers are watching this

[@swecreations]

I love how this new Mclaren looks with that short wheelbase and small overhangs.

[@tkskagen]

I have always considered your Channel as "Food for mu Brain". Chances are I didn't know the Information/context of your Video's beforehand, therefore I have learned something! Always learning something new (not known Information or explanation) every day has always been my goal.

[@EngineeringExplained]

Appreciate you watching! :)

[@krisnadiimam4556]

i suppose decently powerful axial flux motor + gearbox ( automatic or manual doesnt really matter ) is the key for fun and sportier driving EV. Can't wait to see it happening
