Lets Take A Technical Look At The G80 BMW M3

[@KareemBaz]

low key the best m3 vid where I actually learned something

[@juancarlosathome101]

Not trying to be a bandwagon-er, but you should sub... This is 100% the best BMW content on all of YT! I LITERALLY learn something every single time I watch a vid...

Brother I’m only five minutes in and this is one of the best reviews I watched. Thank you so much for all the details especially about the drive experience. I can’t wait to watch the next 19 minutes.

[@aweldum]

Dude, as I am in line to trade in my Raptor on a G82 M4 xdrive and I appreciate this level of detail and insight all around. Being an ICE engineer your dedication and delivery to the info related to the engine and its subsystems, calling out the efficiency improvements that are inherently extended performance advantages... just awesome. Cheers dude!

[@pepsiontherockspls]

What a beautiful machine. Very jealous! It's so cool to see you break down the improvements on past design. Thank you so much for the DIYs. I have a 2011 e90 335i and I've learned a lot watching you.

[@VehicularDIY]

Thanks for watching!

[@RangerRudie]

I've had my 335xi for 2 years and watched your channel from day one. I did dps in my driveway on jack stands after watching you do way more difficult jobs. I'm moving to Texas from NY and just wanna say thanks for all the great content.

[@VehicularDIY]

Thanks for watching, I enjoy making them. Nice welcome to Texas!

[@emperor002002]

At this point I just give your videos a like after I click it. I don't even own a BMW. 😄

[@twinturbo8304]

Someday when I'm 95 years old I might be able to afford one of those. I still have my 08 335IN 54. I am finishing up all of the modifications that you suggested but now I realize it's just an antique dinasaur

[@Fittednocap]

Damn dude you’re so knowledgeable

[@Shamus71]

Beautiful machine. That new grill design isn’t that bad, it can grow on me. Like you said it’s best blacked out.

[@alexmat106]

Regarding compression ratio (CR)...a lower CR effectively reduces the peak temperature in the combustion chamber. Assuming the same peak pressure/air density is required, by letting the turbo do more of the compression work, the in-cylinder temperature will be less since it wasn't compressed as much by the piston. Regardless of CR and boost, the air intake temperature will be the same so by compressing it more inside the cylinder you're increasing the peak temperature. Initial air density doesn't affect the peak temperature, it only affects peak pressure/density.

[@tookiedew]

[@qazwsdrazvan2436]

Great job man ! I really like and appreciate your videos. You re also so helpful with many of my 335i N54 issues ! Thanks and keep doing it , you're a proffesional !

[@angelohollenbach546]

Watched a couple of videos but none like this so much of information thanks. Great review.

[@igotaction]

The other big benefit of direct injection is the DME is not limited to injecting WHILE the intake valve is open. DI you can inject fuel whenever you want (see DPF regen), so you can inject way more fuel and still be efficient whereas 2000cc injectors to make similar power isn't the easiest on the engine.

[@domkraggp9944]

I read an old tech manual on the m52 engines that explained the rationale behind the low cylinder head temp + high block temp configuration. Apparently the lower cylinder head temp means cooler intake mixture.This colder intake mixture has more molecules per part ,which equals more volumetric efficiency. The high block temperature 🌡 results in reduced moving part friction

[@VehicularDIY]

Yeah which makes even more sense for direct injection.

[@domkraggp9944]

Good stuff man you got an M3, the difference between M3 and M335i or M340i is night and day... The whole driving experience is 10x better as I'm sure you are aware

[@SONO4B11T]

Wonderful video👌... It's nice to get a technical insight of the car before one can get a technical training manual

[@karleignr]

Awesome review.. love how you walk through it all.. and the comparisons to the n54/e90 .. seems they took from that book.. not a bad way to say "bye" to ICE .. keep the vids coming!

[@SteveWeltman]

The new G80 series cars are pretty cool but I am still in love with the E90 N54. The review was super good! Excellent work. And nice new car!

[@tookiedew]

Love the suspension comparison shots. Excellent contrast in highlighting the differences

Congratulations on your new car! Well deserved!! Your content is by far the best I've found for detailed, informative, and technically sound information. I'm in the metroplex, let me know if you want meetup for a drive! Thanks again!

[@ShaftDrive]

Looks great, Wonderful information. I love your technical description. Looking forward to more videos.

[@scotttanner1528]

Amazing video, you are so knowledgeable, really enjoyed this. Just wondering why you didn't go for the manual base? I'm looking at buying the manual but my reservation is how the manual transmission can handle more power if I start some minor mods to achieve similar horsepower to the competition? By the way, I'm now subscribed. All the best.

[@TheMOTP]

Thanks for the video, very informative and professional :) I hope that one day I will own one of the modern BMWs. I am actually really happy that the reliability is finally improving.

[@796monster]

First time viewer here, fantastic review and compare vid !, just curious did you give the Manual trans. model a purchase consideration ? thanks

[@VehicularDIY]

Thanks! I didn't as I got used to the assisted riving on my M340i and really didn't want to give that up. I have a manual N54 335i that I drive when I feel itch to drive manual. I converted it from auto to manual. I've also heard that the manual in the G80 is decent but nothing too special as it was carry over from the F30 340i as a way to offer a manual for the small percentage of people that still want it.

[@sxstexanphotography4587]

Very interesting. Great video. I'm strongly considering upgrading my 2018 F36 for a new one.

[@UsefAfande]

You’re making me want to upgrade from my e90 m3 to follow along in your enhancements and upgrades to this car 😄

[@abelucious]

People already falling in love with this new grill, for some reason it makes the regular size kidneys look dated, this is the new look.

[@VehicularDIY]

They seemed to be positively received by people in person. Looking back at the front of my old M340i it does still look great but does seem a bit dated in comparison.

[@sfneurosurgeon]

This large kidney grills are an homage to the BMW’s from the early 20th century.

[@Joro379]

Awesome and super interesting video! Do you think doing a stage 1 with tune and downpipes (or just tune), etc would shorten the lifespan of the engine? Also is there any specific new maintenance that would need to be done? Judging by the video - I think it wouldnt hurt the lifespan, but wanted to ask the expert.

[@Carobears]

Glad I found this channel, I have just subbed. I like your descriptions, not overly difficult to follow along. Several questions for you though...1. How long are you planning on keeping your M3? 2) Are you going to perform all of your own maintenance work or do you plan on having the dealership look after the things that are under the 4 year 80,000km coverage? Keep up the good videos.

No DCT is a major gripe I have with this gen, combined with the weight increase and design choices. BSM is a good color choice.

[@machtschnell7452]

The intake resonator is not a muffler to reduce noise but a resonator tuned to produce standing waves to aid induction pulses. Common practice for last 30 years, especially Japanese higher performance models. "Lose fuel to evaporation" on port injected engines? not really as any "evaporated" fuel is still part of the intake mixture. Not clear what you mean there. My understanding from the BMW S58 introduction video is that the S58 abandoned the stratified cooling scheme of the B58. Pistons, rods and crankshaft are all forged in the S58. Only crankshaft is forged on N54 and some later M2 N55, according to BMW. A national tuner had an early N55 crankshaft out next to an N54 crankshaft and could not visually tell there was any material difference. So .... who knows? Porsches 992 911 run about 9.5:1 geometric compression ratios on their Turbo and Turbo S engines. You know of course that Mahle makes a forged 9.5:1 piston for the N54? Just saying ......

[@VehicularDIY]

Yeah I know that if I was building an N54 I would lower the compression slightly to run more boost on a single.

[@stoss-11]

I don’t understand why don’t build engines you’re so insanely knowledgeable. Where did you get your knowledge from it’s seems like you went to school for it almost hahah . Great video again btw

[@AH4Z]

Excellent info! Thanks!

[@colinwie9192]

Great video. Have to admit I'm Jelly in the legs over such a beautiful blacked out M-Car, considering I'm some D-Bag Audi/VW guy. Still miss my E46 M3.....You mentioned the S58 compression ratio being lower, and higher turbo charge pressure than the B58 engines, though an important aspect of "Direct Injection" engines you're missing is that DI Technology offers the ability to run a piston engine in "Fuel Stratified" or "Fuel Homogenized" modes. Basically, stratified means we run ultra lean squirting in fuel just before ignition on compression. Running a homogenized ratio (1.0 lambda or 14.7/1 AF) means squirting fuel during the air intake cycle, like a port injected engine. If I had to guess, I'd say the S58 compression is lower because the fuel injection is mostly/entirely homogenous based because it allows for a higher fuel/air density, which results/produces a higher expansion ratio, similar to a Diesel engine......

[@VehicularDIY]

Thanks for the input!

[@Crazyalbokid1]

B58 sounds so good

[@VehicularDIY]

Yeah my favorite of the three by far.

[@AX5Z]

[@kierankelleher]

Beautiful M3 - thanks for the inepth technical discussion. Quick question related to ride comfort: Is the M3 ride comfort the same or stiffer/harsher than the M340i ride comfort. If so, would the M3 confort suspension setting be about the same as the M340i Sport suspension setting?

[@chrissmith-rv5ro]

I think the new look is hot. I've seen the shadowline and the other one on the road, distinctive. All the other grilles are big horizontally, this one is big vertically and that makes it stand out. This might be the last grille anyway.

Thanks for watching. I'm pretty happy with the stage 2+ turbos I've been running. If I was gonna go for more power I'd definitely go single turbo instead.

[@eman9372]

Have you seen glare free high beam? It's disabled in the US but I think you can enable it with esys. So with the kafas camera the beam will spread out and make a tunnel for the car in front or shut off a light if a car is passing

[@VehicularDIY]

I have seen the beam pull inwards but not spread apart. Thanks for the info.

[@joshuatran3667]

Is it a lease? I wouldn't want to own this car for the long term. It's nice when it's new but be prepared for the expenses. Plus why get this car when comparable performance EVs are coming (or already here) which are waaaaaay simpler?

[@schuey999]

Gee, anyone want to bet whether the O2 sensors or radiator will fail first?

[@itsm3th3b33]

I may be in the minority, but I happen to like the aggressive front grill. It looks a lot better in person than in photos. However, when I saw one on the road, it had the front license plate. What an eye sore. What do you plan to do with the front plate?

[@VehicularDIY]

I plan on not mounting.

[@BrettL250]

I have a question. I thought there were 10 different settings for their slip differential. Meaning I thought you could set it where the tires would spin out just like the F80 or put the setting on the other end of the spectrum and the tires with catch and not spin at all. Am I wrong?

[@bence.gabor.slezak]

The compression ratio doesn't make a huge difference in power, and paired with direct injection it's mostly for efficiency and emissions. For example, Papadakis Racing went back to port injection with their Supra build. Though they probably use e85 and that cools the intake air even more.

[@VehicularDIY]

Any word on if they stuck with the 11.0:1 compression when they built that B58?

[@bence.gabor.slezak]

@@VehicularDIY They have custom pistons but didn't mention compression ratio in the 4 videos about the supra build, they did a live build at sema, but it's almost 6 hours to watch, they might have mentioned it there. Usually, engine with high boost have a lower compression ratio and na engines can go up to 12:1 with pump gas, even with port injection. S85 S65
