It's fascinating how much time and effort is put into safety in crash. I might actually owe my life to such innovation. In 1990 I not only didn't die, I walked away and provided medical attention to the passengers of the vehicle that caused the crash. After, looking at my vehicle, I could see how it crumpled to spare me blunt force and crushing by the engine. Always wanted to thank some designer, but no way to know how.
Thank crash test regulations. The fact that individual components are functional and designed towards specific crash test attributes means companies are engineering for the test and not necessarily taking initiative on comprehensive safety (e.g. specifically 25% front crash overlap instead of other variations of front crashes).
Great breakdown! Jordan hits it out of the park as usual. He has such a smooth and easy to follow style. Thanks Jordan for some real in-depth coverage that we can follow. No channel does better at presenting complex engineering designs such that even a novice can understand. You all are amazing and Munro as the best people in the industry.
Elegantly simple, exactly what you would expect from a legacy automaker of high performance vehicles. Whether they used legacy components or not (suspension goodies mostly) makes no difference, the marriage of legacy components to their their electric platform has been done brilliantly. Compared to the EQS however it looks dainty, in usual fashion Mercedes components look like if they are meant for a tank (which the EQS is) while these look more like a motorsport focused company. Very nicely done! It shows how a legacy automaker can leverage what they have done and refined for decades into a new product. Excellent engineering. Great analysis.
The i4 is indeed based on the CLAR platform they use for basically all their vehicles, both ICE and EV. I really like how the explanations tied into BMW's historical engineering. It really shows how different companies can take unique approaches (that aren't just variations of cost cutting) in tackling similar problems to add their own flair to vehicles.
@@rkgsdeven the i4 M50 on the smaller wheels and non-summer tires can achieve well over 300 miles IRL. BMW tends to produce quite efficient vehicles. Even their ICE vehicles are usually top of the list for real world efficiency. My old M440i xDrive Gran Coupe had nearly 400HP yet I could get almost 38MPG going 80MPH. It used less fuel than my much smaller and less powerful VW GTI 6MT or my old Honda Accord 2.0T Touring. We have an i7 xDrive60 now and it is quite efficient, returning up to about 3.4-3.5mi/kWh at a steady highway cruise. For such a large and heavy sedan that’s built off an existing ICE chassis I am quite happy. At 80MPH it tends to be as efficient or more efficient IRL than a Model S Plaid while being so much quieter, nicer riding and loaded with options like soft close doors, 4-zone climate, massage seats, reclining rear seats, and a slightly larger battery pack.
Excellent, informative presentation, even for the average layman. Well done! Next up offer the retail costs of those parts to present how often the post accident reality results in a totaled vehicle, along with the required labor charges, etc. This is engineering at the forefront of technology. A+ Jordan...great job!
Wow, what an unusually professional presentation! I don’t know this channel but hats off to this guy! He knows everything he is talking about and makes his points in an eloquent still concise manner! I’m not used to this when talking about cars! Great video, thanks!
I'd be really interested in a video showing how SORB structures are designed and 'tested' in software before they try and crash these cars. Just a thought.
I saw a few drips too, I was wondering if Jordan was going to mention what that was, it looked like to me he thought about it for a second but moved on.
I get that Munro's business is about figuring out and improving manufacturing techniques, but I would love to hear more insight on these vehicles from a durability and overall quality standpoint for the consumer. Thanks for all the videos!
Jordan, superb clarity on BMW design options/choices. Gives us great insight to the normally hidden details we love to geek out on. Cant wait for the drive run down. Interesting to see the ICE compromises, lets see if it shows in use.
@@blackthorncane1841 seeing as how all tesla are in the top 1% of the safest cars ever crash tested? And how safety is a top publicly stated priority for them, I'd bet they'll be even better in a crash with the castings and structural pack's. 😎
@@kkal1183 Why not? If any part of those castings get damaged in any car it's a total loss. No point in repairing since it will need to be stripped and straightened on a bench with chains to be corrected. No one is paying that work. also this car has 4 star safety rating compare to any new BEV being nearly always 5 star. For mass production you want as little amount of part as possible. We seeing here probably over 200 parts, each with their own margins and possible failures. Where Tesla now only has 1 part, since it's a casting the chances of failure is very small. There a reason Munro is trying to convince Legacy car makers to use 1 part casting for decades. It create cost savings, create a better structure, it's lighter part and less chances of failure.
I actually bought the expensive ad thing. was talking to a friend just the day before about wanting a beefy backup battery setup, with the fear of the power going out in the middle of texas heat, and the add-on of solar panels was too good to resist. it probably can't run my AC but at least it can provide shade and power a fan all day
Am I missing the statement or when the observation of the subframe during impact is inclinatated upward into the firewall to avoid the battery....goes into the occupants? Not sure if I was understanding that correctly
please make a direct comparison with the Model 3. For example the quality of the door seals, ventilation of the front brake discs, etc.. That would be very interesting and helpful.
A simply light-weight addition/protector would be a light-weight cage to protect the front motor. Simple, cheap, light. Would take minimal anchors. It could be at little as 3-4 inch mesh squares. Would stop 90% of unforeseen projectile intrusions.
i felt the floor inside has been raised a bit compared to regular 4 series gran coupe. Also it seems ground clearance is lowered, but I can't verified it without both of them side by side.
REAL floor is raised to Accodomate the battery pack , makes it Uncomfortable for REAR passangers , Roof is too short , slope is too much, Floor too high. TESLA floor is Compltely flat.
Really cool under car coverage. Thanks! I believe BMW's used front MacPherson struts exclusively from 1962 until 2010. The 3 and 4 series have always used them also, I believe. The i4 doesn't have optional rear air suspension, but instead it's standard on versions including the eDrive35, eDrive40, and M50. Is that forging that's become part of the battery pack, actually bolted to the rear subframe? BMW claims that these subframes tie to the pack to add rigidity. The pack is a structural reinforcement.
How much to replace a battery module? Could be interesting to see how much the various solutions cost to repair and/or replace. Including Tesla and Nio of course!
@@FrunkensteinVonZipperneck Because why would anyone without knowledge should have access into a battery pack at these voltages? Also the cost to repair a pack would be crazy expensive and risk of a bad job that it can catch fire. This pack has components tig welded directly to the pack. So getting this pack out and repaired / replaced is not going to be easy either. Getting the pack out of a Tesla is quiet easy to get it replaced. To repair a pack require some specialist workshop to do it if the pack is outside it warranty (which is 10 years on Tesla). Still need to find a workshop that does pack repairing with warranty of like 2-5 years that it wont catch fire or break.
Legacy OEMs aren't thinking in scale. As the production of batteries reaches the hundreds of TWH in scale, the cost of batteries will decline to the point where the combined labor and liabilty to replace modules will be greater than the combined cost of just replacing the entire pack itself and recycling and or re-purposing the old pack.
@@carholic-sz3qv How you know? You had any pack repaired by a specialist and have it tested + warranted + certified again? People keep saying that repairing a pack is cheaper but I've not found any proof yet of a legit repair workshop that offer a price for repairing a pack.
@@carholic-sz3qv and is therefore a compromise. This will be to he downfall of legacy auto, trying to make products that fit all perceived markets. Can they make them in 10 hours at 30% profit? No? Doomed....
@@nikelliot8105 lol….. wtf are you even talking about!? Those other manufacturers litteraly makes cars that are then modified/tuned by the customers/ companies for their own usage, from trucks to even the small vehicle to the big trucks, vans……. You are doomed!
Great explanations. Makes me even prouder of my i4 purchase. I mentioned before, would love to see a teardown. Maybe a partially wrecked version? Gotta be some wrecked ones out there. Ever hear of Copart?
So why would you need to add pencil braces and round Z direction extensions to the body around the rear motor cradle? I suspect it's because the motor cradle designers were siloed apart from the rear suspension designers and the result was needing these band-aids to fully mount the motor to the body and not interfere with the suspension. This is not a stellar design for manufacturability implementation and looks ok for a 50k to 100k per year volume, but is going to be a huge headache for 500k to 1,000,000 per year volumes. Prima facie evidence that BMW has still not executed a clean sheet of paper BEV architecture designed for million+ per year manufacturability. High manufacturing costs will eat into their BEV profits.
That's because they have no intention of having this be a high volume vehicle. The purpose of this vehicle is for PR Lip service (Hey look were relevant, we have an EV too!) and emissions credits. For these purposes it does it job beautifully. BMW is perfectly content selling high margin ICE vehicles for as long as they possibly can.
BMW did make the snub nose i3 and while range for that car was abysmal, the rest of the car design was wonderful:) BMW hopefully learned their lesson with the i4 and will correct and replace what is one of the worst designs of the year:)
Stuff like that chunky forged aluminum piece MIG welded directly to the battery pack as an attachment point to the body makes me cringe. So many different mix and match metals and alloys in the underbody. A lot of their solutions look like homebuilt garage engineering with lots of welded and bolted tubes and sections with redundancy galore. Probably why it weighs 5,000 lbs. even though with its small interior it's classified by the EPA as a subcompact.
Polestar is ground up BEV. The reason Polestar was created as a separate entity was purely to separate out ground up EV research and Hybrids on the Volvo stable.
@@twenty-twenty 😅 its not. If the ps2 had been designed from scratch as an EV that would be correct, but its not. Its built on the Volvo CMA platform which is shares with the XC40. The CMA platform was made for ICE and hybrid drivelines. So no, the PS2 is not based on an EV platform, like many other EVs it is fit onto an ICE platform, which comes with its limitations. Most notably you can see this by the transmission tunnel going though the interior of the car, EVs do not have a transmisson so it is entirely unnecessary and steals up interior space.
@@twenty-twenty got a i4 M50 too, got the ps2 in summer of 2020, ordered it because BMW had no sporty electric options at that time. The ps2 was a decent car, but a bit half finished in some regards. I drove it for 99200km in 2 years and was happy with it even with the many workshop visits for minor mechanical and software issues. But the i4 is in another league, the range is better, the tech is more refined and reliable (autopilot on the ps2 made me look like a drunk driver, autopilot on the i4 does its job much better) and the quality feel and ride quality is much better. Im not out to get you, just wanted to point out that it was wrong, people misunderstand all the time, so no worries. I will enjoy being king of the hill for now 🫡 Polestar was created to spearhead the EV tech for Volvo, as they feared it could fail and reflect badly upon Volvos brand image as a safe and family focused car. So they positioned polestar as a more sporty option as to not steal their own customer base and at the same time make a trial EV car using Volvo tech and architecture. Along the way during development process they realized that there was a market for EVs and that EVs were here to stay, so they retrofitted as much as they could into the xc40 (which has a shared platform) and released it shortly after the ps2 release, although they kept the older and more "old people friendly" volvo HMI system instead of doing like polestar and go all in on an android OS (which is good for younger buyers, but your average 60 year old Volvo buyer would not like everything "smart" and digitalized.
BMW has followed a well-worn and bureaucratically institutionalized formula for building its cars...and they are typically beautiful and well constructed vehicles. But we're entering the EV age, and BMW's thinking is too rigid, too stuck, to behave with agility and nimble response in the young EV ecosystem. Even though quirky/clunky appearing, they had interesting ideas with the i3, and after that....crickets. Hard to be *wowed* here with i4.
I am going to disagree on the Galvanized to Aluminum (Al) connection galvanized steel will react with Al. The Al will break down from the galvanized steel would like to see how they stop that from happening.
Great overview, thank you. For all the times where you said, "I think this structural part is for ..". Couldn't an entity with the web footprint of Munro reach out to, in this case, BMW and ask? I would think you could reach the specific engineering team, for example.
great video thanks can you or anyone please share which OBD reader and App you are using? . I have been unsuccessful in getting any OBD readers to work. Thanks Mike
Question for Munro: have you presented a vehicle previously on Munro Live where your team had input in the development, and the input has been applied?
you guys should wash or pressure wash the underside prior any lift. not only they look ugly on camera, particles could fall to your staff's eyes or inhaled
With that "big casting" around 5:10, i had to think of Crocodile Dundee - "That's not a big casting - _this_ is a big casting!" ;-) Nice review, as always, thanks!
@@carholic-sz3qv thanks for the info! Did not want to take anything away from BMW, just found calling that thing "big casting" after having seen the giga castings in the Texas Model Y ... _shakes-head_ 😉
It is kinda worrying that there is no full cover on the front or rear. Both from efficiency and from preservation/weather protection perspective. In harsh winter climates like the Nordics the snow and salt will not be kind to all those exposed components.
I believe all that is covered, and they were removed for the video. They've been doing that for years. Even our 14 year old 3 series is nothing but plastic covers all underneath.
Would be very interesting to compare this structure to the BMW M440i GRAN COUPÉ the i4 is based on (and visually identical to if option matched). I bet there are very few differences and you'd notice a lot of structure that is only there to enable it being both ICE and EV - with disadvantages for the customer.
I was about making this exact comment! Yeah would have been interesting the difference since it’s basically the same car except many modifications. Curious what those were.
There is no disadvantage for the customer here lol….. everything was well tought to make the platform work with both Ev and ICE. Also it remains a very easily serviceable car unlike the tesla big castings
@@carholic-sz3qv Except the interior is tight, there is no frunk, the luggage space is tight and the car weighs 400+ kg too much.. - except those things and probably a lot more I am forgetting "there is no disadvantage for the customer here lol…" Are you paid to defend stuff on the Interwebs? Do they know that you are not good at it?! And what kind of "service" does the chassis of the BMW need that you have to compare it to castings?! Oh, right... BMW of the past used to have issues with cracking sub-frames and shock towers for example...
@@NO3V watch Björn Nylands take on the i4 RWD i40 in these past days. No one tests as thorough and unbiased as him - and he is the biggest Tesla fan. Also, i don't know but your tone doesn't sound like you are an engineer - as an engineer you would be able to debate things properly and not talk down on others.
Stick a camera on this.... under the car and race it. I want to see footage of those control arms going up and down with the suspension as the tires are REALLY tested. I want to see the weight shifting
Great review. One comment Polestar is based on the same platform like Volvo XC40 ICE/BEV platform just like the i4 is based on a multi purpose platform.
They won't! It's a huge efficiency advantage to have the underbody close to the ground, and completely covered with smooth under-body cladding / covers, to decrease drag. And efficiency (should) drive EV design to contribute to range.
It is interesting to see how much of the structure is designed around crash safety. In the past it was directed to a stiff structure under dynamic suspension loads.
Crash safety took a serious leap forward during the 2nd part of the 60's. It has been ongoing ever since, the theme being: Save the passengers, kill the vehicle! (PS: Safety glass came into being prior to the mid 30's...so safety has always been around for vehicle manufacturers)
It boggles my mind why BMW is still wasting their time on ICE retrofits. It looks like they're going to transition kicking and screaming all along the way.
@@carholic-sz3qvnot only is the final product inefficient in space, high in cost, and slow to build, they had to design half of the vehicle from scratch anyway....for a platform that's going to be obsolete in a couple years......No, it's already obsolete. What an incredible waste of their resources.
I really like this guy and the interior guy. They really know the material and how to explain it.
The presenter of this video is Jordan Arocha

It's fascinating how much time and effort is put into safety in crash. I might actually owe my life to such innovation. In 1990 I not only didn't die, I walked away and provided medical attention to the passengers of the vehicle that caused the crash. After, looking at my vehicle, I could see how it crumpled to spare me blunt force and crushing by the engine. Always wanted to thank some designer, but no way to know how.

What car were you in, sir?
Thank crash test regulations. The fact that individual components are functional and designed towards specific crash test attributes means companies are engineering for the test and not necessarily taking initiative on comprehensive safety (e.g. specifically 25% front crash overlap instead of other variations of front crashes).

@@twenty-twenty 😅 its not. If the ps2 had been designed from scratch as an EV that would be correct, but its not. Its built on the Volvo CMA platform which is shares with the XC40. The CMA platform was made for ICE and hybrid drivelines.
So no, the PS2 is not based on an EV platform, like many other EVs it is fit onto an ICE platform, which comes with its limitations. Most notably you can see this by the transmission tunnel going though the interior of the car, EVs do not have a transmisson so it is entirely unnecessary and steals up interior space.
Whatever dude. I have better hills to die on. I own an i4 and I LOVE the empty transmission tunnel because my 4 year old uses it as a hurdle.
@@twenty-twenty got a i4 M50 too, got the ps2 in summer of 2020, ordered it because BMW had no sporty electric options at that time. The ps2 was a decent car, but a bit half finished in some regards. I drove it for 99200km in 2 years and was happy with it even with the many workshop visits for minor mechanical and software issues. But the i4 is in another league, the range is better, the tech is more refined and reliable (autopilot on the ps2 made me look like a drunk driver, autopilot on the i4 does its job much better) and the quality feel and ride quality is much better.
Im not out to get you, just wanted to point out that it was wrong, people misunderstand all the time, so no worries. I will enjoy being king of the hill for now 🫡
Polestar was created to spearhead the EV tech for Volvo, as they feared it could fail and reflect badly upon Volvos brand image as a safe and family focused car. So they positioned polestar as a more sporty option as to not steal their own customer base and at the same time make a trial EV car using Volvo tech and architecture. Along the way during development process they realized that there was a market for EVs and that EVs were here to stay, so they retrofitted as much as they could into the xc40 (which has a shared platform) and released it shortly after the ps2 release, although they kept the older and more "old people friendly" volvo HMI system instead of doing like polestar and go all in on an android OS (which is good for younger buyers, but your average 60 year old Volvo buyer would not like everything "smart" and digitalized.
BMW has followed a well-worn and bureaucratically institutionalized formula for building its cars...and they are typically beautiful and well constructed vehicles. But we're entering the EV age, and BMW's thinking is too rigid, too stuck, to behave with agility and nimble response in the young EV ecosystem. Even though quirky/clunky appearing, they had interesting ideas with the i3, and after that....crickets. Hard to be *wowed* here with i4.
Really good analysis! When will the engineers of the motor/gear box talk to the chassis engineers and make a unified structure?
Thanks Jordan!
You bet!
excellent presentation
Glad you liked it!
Very informative video, thanks again.
My pleasure!
I am going to disagree on the Galvanized to Aluminum (Al) connection galvanized steel will react with Al. The Al will break down from the galvanized steel would like to see how they stop that from happening.
Maybe certain types of Al or Galvanized steel does not react? I am sure a coating or certain formulas eliminate or min this reaction.
Rear air suspension is standard. At least in Europe. I think in the US too.
I always love to take a look underneath a vehicle ^^
13:10 - missed an opportunity for "MunroAnchor" :D
Great overview, thank you. For all the times where you said, "I think this structural part is for ..". Couldn't an entity with the web footprint of Munro reach out to, in this case, BMW and ask? I would think you could reach the specific engineering team, for example.
great video thanks can you or anyone please share which OBD reader and App you are using? . I have been unsuccessful in getting any OBD readers to work. Thanks Mike
would be nice if u label the sponsor sections in your videos. great work nonetheless. Thank you!
Question for Munro: have you presented a vehicle previously on Munro Live where your team had input in the development, and the input has been applied?
Clubcar golf cart.
every TESLA teardown, this was the case. only 3 mos from Unibody to 3 part Castings and 1 month to Single REAR casting.
So what’s dripping at 9:08? Does this vehicle have a leak already?
Aluminium leaks with dirt? It's definitely a dirt
I wish they do a teardown of the wound rotor Synchronous motor that BMW uses. Please Please Please...
Looking forward to the engine teardown and analysis.
Is there a tl'dr version of this?
THANKS4GIVING
you guys should wash or pressure wash the underside prior any lift. not only they look ugly on camera, particles could fall to your staff's eyes or inhaled
How does it drive though?
Polestar 2 is not a BEV only platform. Hence the lack of room inside.
A summary at the end would be very helpful!
Nice job. Any clue when the next 4680 Model Y video will be released to TH-cam?
With that "big casting" around 5:10, i had to think of Crocodile Dundee - "That's not a big casting - _this_ is a big casting!" ;-)
Nice review, as always, thanks!
Bmw was actually one of not the first to use those giant castings! Munro did a video on it in 2013 with AUTOLINE network go watch it!
@@carholic-sz3qv thanks for the info! Did not want to take anything away from BMW, just found calling that thing "big casting" after having seen the giga castings in the Texas Model Y ... _shakes-head_ 😉
Very comprehensive and informative! But is this "a) [whatever], and 2: [whatever else]" like, his signature move or something? lol
It looks mig welded fyi just from visual glance. Aluminium is completely mig weldable.
It is kinda worrying that there is no full cover on the front or rear. Both from efficiency and from preservation/weather protection perspective. In harsh winter climates like the Nordics the snow and salt will not be kind to all those exposed components.
I believe all that is covered, and they were removed for the video. They've been doing that for years. Even our 14 year old 3 series is nothing but plastic covers all underneath.
Would be very interesting to compare this structure to the BMW M440i GRAN COUPÉ the i4 is based on (and visually identical to if option matched). I bet there are very few differences and you'd notice a lot of structure that is only there to enable it being both ICE and EV - with disadvantages for the customer.
I was about making this exact comment! Yeah would have been interesting the difference since it’s basically the same car except many modifications. Curious what those were.
There is no disadvantage for the customer here lol….. everything was well tought to make the platform work with both Ev and ICE. Also it remains a very easily serviceable car unlike the tesla big castings
@@carholic-sz3qv Except the interior is tight, there is no frunk, the luggage space is tight and the car weighs 400+ kg too much.. - except those things and probably a lot more I am forgetting "there is no disadvantage for the customer here lol…"
Are you paid to defend stuff on the Interwebs? Do they know that you are not good at it?!
And what kind of "service" does the chassis of the BMW need that you have to compare it to castings?! Oh, right... BMW of the past used to have issues with cracking sub-frames and shock towers for example...
@@NO3V watch Björn Nylands take on the i4 RWD i40 in these past days. No one tests as thorough and unbiased as him - and he is the biggest Tesla fan.
Also, i don't know but your tone doesn't sound like you are an engineer - as an engineer you would be able to debate things properly and not talk down on others.
The i4 video is not an i4 video if nobody writes the ICE platform comment 😄
are you allowed to do partial tear downs of a press vehicle?
I imagine BMW welcome the feedback.
They just took of the bottom covers. So not really a tear down. This is what any inspection of a car would do.
You should use a colored pointer stick to show us non tech people. It would really help.
Stick a camera on this.... under the car and race it. I want to see footage of those control arms going up and down with the suspension as the tires are REALLY tested. I want to see the weight shifting
Laser printer?
no comment about the drip drip leak when under the front tho Jordan ??
It was water, the car was just washed because Cory took it home overnight and lives on a dirt road.
Great review. One comment Polestar is based on the same platform like Volvo XC40 ICE/BEV platform just like the i4 is based on a multi purpose platform.
OUTDATED gas car Platform.
When/Will conventional passenger EV’s have greater underbody road clearance? And why will it happen if/when it does?
They won't! It's a huge efficiency advantage to have the underbody close to the ground, and completely covered with smooth under-body cladding / covers, to decrease drag. And efficiency (should) drive EV design to contribute to range.
It is interesting to see how much of the structure is designed around crash safety. In the past it was directed to a stiff structure under dynamic suspension loads.
Crash safety took a serious leap forward during the 2nd part of the 60's. It has been ongoing ever since, the theme being: Save the passengers, kill the vehicle! (PS: Safety glass came into being prior to the mid 30's...so safety has always been around for vehicle manufacturers)
Wouldn’t it be better just to have single piece castings front and rear?😆
My family has a BMW e34 with an m50 engine. I swear to God, this is going to be wildly annoying when trying to Google things about our engine.
well done! More comparisons and high level opinions while you go through he design...
Is there no protection COVER??? WTH
Plz do teardown 2W EVs from China or India or West too
👍👍
With all this structural reinforcement why did the i4 score so low in the Euro NCAP crash test? Only 87% compared to Teslas Model Y with 97%...
It boggles my mind why BMW is still wasting their time on ICE retrofits.
It looks like they're going to transition kicking and screaming all along the way.
Lol….. there is no time wasting here! They made an EV which is the great thing!
@@carholic-sz3qv It has no frunk. They haven't made a good EV at all.
@@carholic-sz3qvnot only is the final product inefficient in space, high in cost, and slow to build, they had to design half of the vehicle from scratch anyway....for a platform that's going to be obsolete in a couple years......No, it's already obsolete.
What an incredible waste of their resources.
@@ccengineer5902 bullshit!!!!! It was already not a very practical car to begin with! Try again!!
@@yatinkheti2427 that’s what she said!!!! Lol….
