I looked at an M240i before getting the M2. I really liked the idea of the xDrive for a year-round daily in Minnesota plus you just pin it and go from a stop. I thought it was a lot of car and performance for the money. But then I always wanted an M car and this M2 came available and the price was right.

I own and M340i an M2. The B58 is a seriously impressive engine, sounds great, linear, responsive. It makes peak torque very low in the RPM band so it feels effortless to drive quickly. I don't have enough miles on the M2, but my initial impressions are the S58 feels a touch laggier by comparison. The Xdrive is uncanny with its ability to find grip, you can go 100pc throttle in the wet and the car just grips instantly with no drama. Depends what you are looking for in a car, but looking purely at the B58 there's really not much I can critiscise it for.

The B58 is tuned for maximum torque off the line, and flattens out at about 5500 RPM. There's no reason to ever shift above that threshold. It's a great engine for daily driving and getting quickly off the line. You're going to get bored very quickly though, when driving spiritedly, specially with the 8ZF tune in the M-Lite.
The S58, specifically in the M2, will make power all the way to its 7,200 RPM redline. That makes it more engaging in high performance driving scenarios and track use, specially with a manual gearbox. Having driven the G87 with both an automatic and a manual gearbox, I would still take the manual for maximum enjoyment. The 8ZF is ok, Even with the more aggressive tune, it's still a slush box. A Dual Clutch transmission would have been a different conversation, though. Those are my two cents having owned both cars.

I'm also in break in so can't really compare the S58 yet, the aforementioned lag is the only thing I noted. My M2 is a manual so it scores higher on the engagement factor because of that. I really do like my M340i a lot, as an all around car its hard to beat. The M2 doesn't feel dissimilar, which is a good thing. The G series in general is so well sorted.

Of course there. Shifting above peak HP is frequently advantageous in order to maximum drive axle torque at any given vehicle speed. Suggested reading here:https://glennmessersmith.com/shiftpt.html M240i with ZF8 speed automatic here under full throttle acceleration from a standing start. Note the tach reading - shifting well above 5,500 RPM as programmed by BMW drivetrain engineers. Optimal shift points for maximum acceleration is when the engine torque * gear ratio multiple in the lower gear (e.g, 2nd) is where it'll be in the next highest gear (e.g., 3rd) using the same equation, realizing that torque multiplication the next highest gear (3rd) will be proportionally lower to the change in ratio).

More. Here are the shift point calculations for my 2018 VW GTI (with Neuspeed Power Module set to + 5 PSIG boost).
I'll note that I'm a mechanical design engineer. (Some folks on the forum have dismissed and even mocked that, as though mechanical engineers have nothing to do with BMW M car design. ) The way to do this is to begin with chassis dyno results (preferably in the 1:1 ratio, though it really doesn't matter) and combine that with final drive ratios in each gear as I've done here. Note how optimal RPM shift points (e.g., 1st to 2nd vs. 3rd to 4th) DIFFER. Most people instead shift at redline ever time (or even worse at peak engine torque - LOL) and lose to their counterpart in the exact same car who shifts like this.

Previously I had the M140i it was pure RWD madness, not for the uninitiated, my first introduction to BMW. The G42 M240i xDrive is safe, predictable, but not a drivers car. I was curious about the G87 M2, so took it for a test drive, 20 mins later when I handed the car back with brakes still smoking, I had the biggest smile on my face, I couldn’t place the order quick enough. Still 3 months to wait, goes in to build next week. Last edited by G87M2GS; 04-23-2024 at 05:25 PM.. Reason: Missed ref |

I'll also add that smoking brakes on a new M2 on public roads is pretty much impossible. Only brakes I ever smoked were those in my then new 1986 Mustang GT. Sliding single piston cast iron calipers with 10" font discs and 9" cast iron rear drums...And that required many very hard and consecutive stops over a six or so minute period in a situation I won't won't further elaborate on here. I was 22 years old when that happened. I just don't even remotely believe that you "smoked the brakes" on a G87 M2 unless you post a video of it. Last edited by m2not1LE; 04-24-2024 at 04:57 PM.. |

I owned (f22) M240i. Tried real hard to modify it to be more than what it was. A great car for me? YES...and the newest Gen probably even better. Thought I would miss that vehicle but the second I drove off the lot with the '24 M2 I never looked back.
G87 is one of the great BMWs. Step up...you will always wonder what if.... |
