I read some news that the 2024 refresh of the BAC Mono gets an improved engine that sets an incredible new record for BMEP / torque density for naturally aspirated engines with conventional cylinders (road car), beating the engines of Valkyrie, T50, former record holder 458 italia, etc. How is that possible with what appears to be based on a Ford engine? If you can get your hands on the new 2024 version next year maybe you can put it on a dyno.

It's a fat little one, that M2. At least it doesn't have such an ugly front end of the M4.

It’s not fair to compare it to the non comp version

@@bradenmchenry995 The comp will be even heavier, most likely.

@@ARentz07this is the comp version it uses the real M engine. There is a cs version coming

Same bro 😭 I mean, it doesn't look bad, but it's nothing compared to its predecessor…

I look at the F87 M2 and think, "too soft and rounded" 🤷‍♂

​@@kayronmercieca8226Fair, but it is cohesive and not a Picasso where all angles are off. The car looks like it has Strabismus Syndrome, especially in the back.

I saw a couple on the road in this exact blue and I was like damnnn that actually looks good. Personal opinion, don’t hate on me.

@@LordStaindI wouldn't do that, my experience differs. I didn't see one on the road and went to my dealer. The car looked so bland, granted in white, that I asked whether they have one in the showroom while standing right next to it. I just looked past it like I do with Golfs and Toyotas. For me, it looked even more dull and boring in the flesh.

Fat. It‘s fat.

It's the friends the M2 made along the way? Idk.

It's blue

It’s 6 feet under

Ha, yes exactly! I have a video in my backlog awaiting release where I dive into this!

The old M2 was based on the old RWD 1 Series. Since the new 1 series uses a FWD platform BMW had to take the M3/M4 platfom. That explains the weight difference compared to the old M2@@EngineeringExplained

Exactly, the Cayman example shows this as well.

@@lucascla the 2016 M2 was based on the 2 series that came out in 2014.

You're feeding Jason with fanatic reasons his Miata is the best modern sportscar money can buy today, hahah

They should call it an M4 minus then.

ah yes the M3.5

The M2'snt

Homeslice did not finish the video

M2x2

It weighs too much for an oil tanker. For a sports car, it's like they've tried to generate downforce by giving it a gravitational field... (Technically everything has one, but I'm just ruining the joke with nerdery at this point).

All cars get heavier though. The new C63 (with a 4-Cylinder) weighs as much as an E-Class.

@@DefinitelyNotEmma the new c63 is hybrid so that accounts for the weight. The w205 c63S is 3900 and the e63S is 4300lbs. The new M2 being as heavy as a 4 door sedan is crazy

Drive one and you will learn the error of your comment.

@@jamesonmiller5799 would handle better at 3500lbs.

@@7mpowerd Of course it would….but it already handles better than any other compact car as is - it just broke the Nurburgring record.

Ive never been to the track but Id imagine the heavy weight will cause bigger fluctuations in tire and brake temps when trying to control them. Also that weird feeling of the stability control masking the extra weight going in and out of corners.

Aftermarket has been in-step making way longer consumables like endless pads, since the factory pads are dust bunnys and melt. It still is setting records as per Jackie Ding's Channel with almost No mods is slaying 600 lbs lighter stuff. So it's heavy but it's still dominating.

@@pacoflyer Yea it's fast no doubt, been following Jackie's stuff too. Just saying that tires like the A052's are gonna get destroyed in a weekend of racing/tracking. That's hardly sustainable for regular fast lapping/racing...but, I guess if you're dropping $65-70k on an M2, running costs may not be that big of a concern 😆 Don't get me wrong I'd love to own one as I really like this M2, but cheaper consumables/aftermarket are what keep me on the 86 platform.

​​​​@@mr.m2137These aren't issues as stated. This car is extremely capable regardless of tire and brake temps and fluctuations aren't really a performance issue. Million variables there. The main issue with heavy fast cars on track is that kinetic energy increases exponentially with speed (KE=0.5MxV^2). Converting that to heat energy (braking) is very taxing on tires and brake pads. The concern there is very quick wear out of consumables (maybe 2 weekends on a M2) compared to something like a Miata (once a season).

New M2 is great news for people who want an M4 but want to spend less. Bad news for people that want an M2. Weird conundrum

Manufacturers for the most part are styling cars simply to stand out, not to look 'classicaly' good. It is baffling but it is what it is.

The new world of internet shock and awe has changed the landscape for the worse on many fronts..

New cars are selling well, I think they made good decision regarding styling.

​@@currycel470that's not a good sign. Just shows taste and style are being lost in the quest to be "different "

@@Decrepit_biker exactly, it’s actually symptoms of a demoralized degraded society..

Bro that was rough 💀

It's not that it's ugly, but my town has a curfew on BMW drivers - they're not allowed out before 10pm to avoid forcing kids into therapy.

I am now aware that things happened to the M2

You weren't aware that it got ugly af?

Looks fine in person, always thought the previous M2 was too aggressive for the size

​@@Rookiereecesir, you should have gone to specsavers.

The funny thing is that the M240i looks better

Virtually all of BMW's last gen cars looked better than their current updates. I think we've hit peak BWM design and it goes downhill from there.

@@richardnavratil9661 I think you have the inability to move on

FWD, yet another reason BMW is going to shite

People have been putting the 4.3 from the last gen in the new gen cars! Might be worth looking into if you miss the shorter gearing, apparently it's a super easy swap since the two gens are basically the same car under the skin (besides engine and some chassis stiffening changes)

I wish I could say the same about my zf8...

@@TallnerdyguySame boat haha, mine blew up in a F chassis BMW

It's also technically not an auto, it's electronic

@@Tallnerdyguy does it change gears automatically?

@@Tallnerdyguybrother it has a torque converter and is most definitely an automatic

Maybe it's all the sound deadening material and hydraulic/electronic mounts and dampers they need to use to isolate the drivetrain from the cabin, something model 3 doesn't need to bother about. In this way, ICE cars are directly competing against EVs.

@@mofayer Why would you need so much sound isolation in a sports coupe though?

@@Spike00773 ask BMW, they've been hell bent on isolating all drivetrain and chassis feel for the last 2 Gen of their M cars.

In my eyes, it's still an m2, it's smaller than a m4 ,more compact, and doesn't have that goofy front grill design. Don't care what pepole say, I will take this Over the previous gen all day

Yep, discussed in video, it's a strange positioning to me.

Uhhh isn't that what the last one was

Jason, this makes the M2 more twitchy and unpredictable and that's.....a good thing??😅 @@EngineeringExplained

Of course it’s detuned. Just take a look at the acceleration numbers (for example Carwow) and it’ll become clear. Easy to manipulate a dyno.

4.4 inch wheelbase difference is actually alot compared to the g82. New M2 should be 200 lbs lighter from this alone imo, but BMW found a way.

No its not "protecting" them, this motor can take 750 hp/tq. It's slowing the spool on purpose to get that "rush" feeling. I believe it's engineered to be slow on purpose. It's also tuned that way to make the M4 "Feel" faster.

@@pacoflyer True to some extent, but you not taking OEM design requirements into account. How long will this engine last at 750bhp? OEMs design engine to last for 200k to 300k miles, so I'll stick to my opinion that it's torque management to ensure longevity of the engine.

I wasn't at low RPM (4,000 as stated in video); it was most definitely turbo lag. Additionally, regardless of why it happens, there is about a second or so between WOT and full torque. If the rods couldn't handle full torque, why would they suddenly handle full torque one second later? Turbo lag is a real issue, sure you could use an electric turbo to get rid of it, but this doesn't have this. Engine management isn't going to be sufficient, there's a process that has to happen which takes time. True for basically all modern turbos (with the exception of electric, but even then there is a small delay).

@@EngineeringExplained Thanks Jason, makes sense since I wasn't sure at what rpm you went WOT. In the aftermarket tuners have been able to almost eliminate turbo lag by experimenting with ignition timing, variable valve timing and lift, and turbocharger wastegate control where they force the turbocharger wastegate shut at low rpm reducing exhaust pressure bypassing the wastegate valve and allowing the turbocharger to spool up faster. Along with a decrease in ignition timing and tuning the VVT&L systems aftermarket tuners have been able to spool large turbos up on small capacity engines in contrast with older tuning methods whereby the pressure holding turbo wastegates shut slowly builds up as charge pressure builds. Don't get me wrong, I'm sure BMW engineers know what they're doing, however I also believe BMW still targets a fine balance between reciprocal mass necessary for turbo charging vs rev happiness - the way we all know traditional BMWs were. A final thought, is the example of Honda K-series engines (K24 in particular), and how their factory fitted forged connecting rods can produce 500+ bhp sustained at high engine rpm, provided that boost pressure is ramped in slowly and reaches target at 6,000rpm, however the same connecting rods fail and destroys the engine if the same target pressure is achieved much lower in the engine rpm range, say for instance 3,500rpm. Thanks for your reply. Much appreciated 🙏🏻

Its not turbo lag, it is boost threshold!! Because the parallel twin turbo setup en low compression ratio this is more noticeable. The good about this is the high output at high rpm, it doesn’t get out of breath. Shame that you as a engineer has not invested more time in the details and technical side of the engine instead of making a video for more views.

Little diff change, and you get what you want.

100% agree. People tend to forget how heavy F87 comp was . It was over 1650kg with full tank vs G87 1725kg with full tank with carbon roof and buckets around 1710kg ... To heavy? Yes but not that big difference as everyone is saying.

But they didn't weigh the same... 175 lb difference, which is significant. Ride with and without a passenger in your car, and you'll notice the acceleration difference.

@@EngineeringExplained a m2 competition mt is 3600lbs. A m4 mt is 3625. Virtually the same. The OG is lighter, but the m2 wasn’t some featherweight version of the m4. It has always been as heavy with the same engine. The smaller size just makes up for less advanced and cheaper body materials. BMW didn’t make the G87 heavy, they just used the same engine to start.

Good point, but 500-600 lb. love handles? At some point, it’s an M4 with the M2 trim package and not an M2 anymore.

@@chriskelvin248 completely understand. wish they'd just be more transparent

@@tier1detailing Until the average consumer starts caring about weight, it’s unlikely we’ll get a breakdown of where engineers put all the fat. Heck, even the average enthusiast only ever cares about 0-60 and hp/torque figures. The amount of “power negates weight” sentiments in car channels is unbelievable.

​@@chriskelvin248I'm sure there are some differences ,it's not the same I'm all aspects

You don’t notice until you drive something 500-1000 lbs lighter. I’m sure it’s a fun car to drive but when you approach the limits and attempt to recover you will feel the weight.
