The Lucid Air is the new kid on the block looking to enter into the small world or “luxury” electric vehicles. And the CEO of this company is Tesla's Ex Chief Engineer of the Model S Program, Peter Rawlinson. We got to meet up with Peter and pick his brain on the Lucid Air, and see what they did differently to make the world’s longest range EV. It turns out, it’s all about efficiency.

  • Am I the only one getting a very dodge stealth vibe off the front end of this thing? The cars are clearly well thought out and amazing, I’d like to see these EV companies start putting together something like a crate motor so us swap crazy folks can make it the new LS type craze.

  • What you fail to mention is the 517 mile version cost $160,000 and the base $60,000 version only has a range of ~400 miles. Efficiency may be great and all but it’s expensive. I understand Lucid is luxury

So we can place plywood in the back without a truck. No sexy car can do this. As a competent volunteer fireman, I’ll us the speakers to spread the C pillar to 50. Dont Tesla’s engineers think this big?

  • I am so excited for Lucid to release their vehicles. I just want more EVs on the road man. Who cares what type. Personally, I am not that into Lucid because they're funded by the Saudis and oil interests might complicate the EV revolution. However, if it just turns out to be a money source and Lucid is still hardcore green tech, hell yeah! V2G is what I really hope Lucid incorporates in their lower end models in the future. Personally I love Tesla, hence SR+ in the name, but the real goal is EVs.

  • Dude, all great but if you would work in automotive industry you would know what this dude was all about. Also your story about motors is complete horse shit, because you keep talking about PM (Permanent Magnet) motors being superior and all the stuff, but you forget to mention than PM machines three extremely big problems with them: 1. when you are using magnets on the rotor your rotor is only limited to circa 120 Centigrade temperature, otherwise magnets will start slowly demagnetise (150C being a critical point) - if you decide to start cooling the rotor you will get such a poor reliability and increased friction - it's essentially not worth it 2. PM machines are limited in how high RPM you can get out of them before you will start hitting flux limits, and also when you will put a lot of magnets in the rotor your rotor will become very heavy and will start inducing strong gyro forces on the vehicle 3. PM are very expensive and Neodymium is available from only one country on the planet in sufficient quantities to make large amount of vehicle - China - and supply chain management 15 years ago when Tesla dev cycle was started had very large question marks around China. This douchebag wanted to lock Tesla to poor technology with poor reliability and dependant from supply in China. His departure was considered a right move even by the people that were outside of Tesla. Stator cooling is nothing new - it's just like saying that dude innovated with something that ev motors were doing for last 20 years ... Story about cogging torque is just a smoke screen, it was never considered a problem and dude is bragging with solutions that were used in the market for decades now. In ev world anything between 200V - 500V is considered "low high voltage", anything above 500V is considered "high high voltage" ... amount of problems you get when you start entering high high voltage is considered now a bad design practice due to servicing and life span. Having battery with more cells in series rather than in parallel makes single cell going of of specification, affect the battery more - the 900V configuration vs 350V configuration will be at least twice as badly affected by cell misbalance, and result in vehicle loosing range far sooner. Your magical transistors are all fun and games but are pice of shit in terms of longevity ... bad idea if you want to build a vehicle with them - this is why everybody is staying way clear of them for time being. So, slow clap to you guys ... how fancy was the hotel and perks for this vid (so you did not had to mention that it was sponsored according to US law)

  • I'll make a prediction: Tesla will go down the route of Apple. They started out by innovating but will stop it when they've gained a cult following and start making mediocre products that cost much more than their competitors, but people will still buy because it's Tesla even if the cars are shitty (Apple RAM costing twice as much as other RAM anyone?)

  • Good breakdown. As you said at the end. Competition benefits the consumer's in the end. Also the lucid and most evs do not have a transmission per say. Rather it's just a single speed reduction gearbox. So far only the Porsche taycan and upcoming etron gt have a 2 speed rear gearbox.

  • So let's put one thing straight. When you go higher in voltage yes you can make the wire thinner because the current is lower, but because you have higher voltage you need longer wire. That not only undoes the thinner wire advantage, but because the wires need to be insulated and insulation can only be so thin, the wire packing density goes down. Another gotcha on this is that because of the higher voltage you need to use higher voltage semiconductors which have significantly higher resistance. Another disadvantage is that longer thinner wires increase the thermal path making cooling more difficult. There are basically laws of diminishing returns. I've done a lot of this over the years and there is basically a sweet spot where the result is optimised. 400V is around about it. There are reasons why you might go for higher voltage, but they are more related to charging and batteries. I'd like to see a proper engineering analysis of where all the losses are before I would comment on Lucid's range. Overall weight would be a big one.

  • Some cool data, I'm a droneracer and we migrated to highvoltage setups 2 years ago to improve performance, and efficency, and got better throttle response curve too as high voltage setups get more resolution to the ESC (the mosfets) to control the motors getting better control of them. Our motors get cool by their own propellers maybe thats a better easier solution to cooling this motors too using some kind of edf fans??
