just did a back to back comparison M2-M2C

went back to my dealer and took out my 17 M2 that i traded. i had put about 150m on the M2C so i thought it would be a good time to see what the difference in driving was.

The first thing is the M2 has sharper throttle response the M2C feels lazy the difference is the M2 has peak torque @ 1400 vs 2450 for the M2C. The M2C likes to rev more you feel the power build the M2 runs out of steam @6k . I always considered the M2 a solid car but the M2C feels more so.

The body movement seems more tidy on the M2C. The steering feel is the same on both cars (not great). You can feel the weight the M2C feels heavier and bigger. The M2 has a lighter more nibble feel. So to sum it up more power, stiffer chassis, same steering feel , feels more front end heavy. Bottom line its not night and day.

Some things on the old car i think are better its snappier and feels more nimble . Im not sure if i would have had a chance to compare i would have run back with a check. I do like the new one a little better mainly for the engine . carl

If your looking for a big step up from your M2 the M2C isn't it. Its the same car with more motor, brakes and chassis stiffing . Down side its less snappy and you can feel the weigh on the front. Remember i'm talking about driving them back to back for about a hour each freeways and canyons . carl

Wonder if you can tune the s55 to have similar n55 low-end torque ?

The one thing that i was hoping for was better shift linkage. That was my number one dislike on the M2 it's not fluid kind of clunky or notchy . I had read that they did something to improve it but its the same . When you shift its two movements . First to neutral then into the next gear. carl

The shifting should get better as the gear box gets some mileage on it .

You certainly can...but you're most likely going to be dealing with more torque then that n55 down low.

Then traction becomes an even greater issue.

S55 can be turned into monsters easily

Go check out the M3/4 board and see what's been done. It's not a new engine, people have put it through its paces.

Thanks for the review. The M2C is new so I wonder what effect that would have on the comparison.

I pulled these charts that were made from BMW data. It shows the Horse Power and Torque curves of the M2 Competition and M2. If you take these charts at their value, even though the M2 develops its peak torque at a lower rpm, the M2C matched it even though the M2C wasn't at its peak yet. Which means theoretically the M2C should be just as fast at lower rpms and then getting substantially faster from there on out.

So in essence, perform some engine and suspension mods to the M2 for M2C-like feel. Perform some weight saving measures to the M2C for M2-like nimbleness. Unfortunately, shaving (substantial) weight is expensive. Who will be the first to opt for all of the CF body panels offered by M Perf? Someone with a lot of money, for sure.

But then that wouldn't really be a fair comparison?

Isn't it only a fair and even comparison when they are both in factory form

tnx for the review.

That said, torque below 2500 rpms to me is meaningless. I'd much rather have the broader power band of the S55 which keeps building beyond 6000 rpms.

I would not expect vast differences in the two cars. The lack of perceptive throttle response may or may not be an issue for some.

My expectations: M2C, better engine, better power band, stiffer front end, better brakes; and yes more weight which most will never notice. Add, more aggressive and pleasing to me exterior.

Thx -

low end torque what makes the car fun to me on the streets - don’t need crazy power after 65 mph

I looked into the MPerf Hood for my OG. It alone is CAD $10K - unpainted. Um...no thanks. Looks like M24 will be getting my $$. Only CAD $2,500 for that.

Yup, your talking peak tq of 369 vs 406. So in fact the detuned S55 in M2C could very well be making same tq at lower rpm. It will be nice to get some dyno overlays in the future. Surprised some hasn't dynod an M2C yet.

The S55 is last powerplant BMW makes that has a little character of early rev happy NA M powerplants. Very much enjoy the powerband of the S55 at the track, it really is a peach of an engine.

Agreed... I think I may be under 2500 rpms backing out of the driveway.

I'm merely pointing out that both cars can be tweaked in order to gain the superior characteristics that each car possesses.

Thanks for the comparison, Carl. To me, a used M2 seems like a great deal right now. Lots of people have been putting them on the market in order to chase the M2C, and prices have been coming down.
