M2 vs 340/440?

Not attempting a flame war or anything as one is a true /M (depending on your criteria) and the other is, at best a M sport.

But.. Has anyone seen the BMS post in the "other forum" with the initial dyno numbers that the 340i put down? Looks waaay underrated with that new engine/turbo with 320whp+ and 360whp with the alpha tune that Terry whipped up within about 24 hours of getting the car on pump gas.

Just speaking from a straight power output, that seems right on the heels of what is being expected from the M2 right? Do we know if the M2 will use the N55 or is it getting a B variant that seems to breathe much better (the graph not only puts out more power but holds it much better to redline).

A Challenger Hellcat would be fun for a weekend.. but it's pretty much of a one trick pony. The BMW 340 with a track package would be a great car if you wanted something larger and more comfortable but still reasonably fast. Mercedes AMG450 would also be in this class. They are not as hard edged as M cars and aren't as fast on a track but that is exactly what some people want. The 340 is also likely cheaper if you lay off the options. If you want a fast daily driver and have kids, it might be a better choice.

Yes. "We" have known the exact engine in the M2 for months. All of the information is here: http://f87.bimmerpost.com/forums/sho....php?t=1183416

having driven many F-series NON-M cars, i have found NONE of them to be enjoyable. To me the 340i is probably another fast appliance just like the F-series 335 is.

the M2 is not an appliance....it's a sports car. Big difference, IMO.

I said the Hellcat as a bit of a joke....since people on these forums seem to think that HP somehow equates cars and determines superiority.....which it doesn't.

3 ounces of Brie cheese isn't the same as 3 ounces of Kraft american cheese slices! The only common ground is 3 ounces of milky cheese. Same goes for HP, IMO....

It actually put down 330 whp STOCK and 380 whp on the alpha tune.

Damn...

The M2 better have a bigger snail on it vs. the N55.

Very impressed with the numbers the 340 is putting down. If I wanted something a bit bigger and softer that would be the only choice given you can get it with a 6MT.

Thing is.. even my 135 had more than enough power and torque for my driving. It would pop up to 3 digit speeds so quickly that I really had to watch it. I think the M2 will have plenty of power and given the parts they swapped in from the S55 will spool up in a satisfying fashion. What I'm really looking forward to are those suspension bits from the M3, suspension tuning, M brakes, and (hoping) better steering.

Oh I agree. Just commenting, for many people, driving feel and balance take a back seat to straight line performance.

The M240 with this engine could very well be a beast of a car in that regard. Even more potent than the M2 unless they up-size the turbo. Not everyone will spring for big brakes and better handling when they're simply interested in playing swing the needle.

Obviously, you think it will be getting a larger turbo.

Let's hope so!

The BMW published engine specs for the M2 say 365 hp @ 6500 RPM and 343 lb-ft @ 1400-5560 RPM: http://www.bmwusanews.com/newsreleas...d=2464&mid=550

They're talking about wheel HP here, a generally more concise measure.

The B58 in the new 340i is rated at 320 HP by BMW but Burger Motorsports, a masterful aftermarket tuning company, measured 331 wheel HP. This is nothing less than ridiculous. The S55 (M3/4) is rated at 425 but puts down, depending on the dyno manufacturer, close to 425 wheel HP. It's underrated but not as much as the B58.

Given the M2 uses the N55 (335i/235i), I'm not so sure the 365 claimed HP will be as underrated as the other 2 engines......The 335i puts down around ~290 wheel HP and has a claimed 300. We won't know how strong the N55 in the M2 application is until someone straps it on a dyno.

Oh. I see. That's interesting. Hopefully one of the auto journalists will put it on the dyno and we will know in February/March. I recently saw a journalist test a Jetta and something tells me the interest in the M2 on the dyno is higher than the interest in a Jetta on the dyno.

Ha, yeah by a slim margin.

My gut tells me the M2 is going to trap, with DCT, between 112-114 which is E9x fast. That's pretty darn fast (substanially faster than M235i) for a car meant carve up canyons and twisties. People won't be disappointed with its power output.

I'm on a local M2 waiting list but decided to pick up a 340i 6-spd M-sport w/track handling package after a test drive. If the yearning is still there for the M2 by order time (April, per my dealer), the 340i will go to the wife. In the mean time, the B58 motor with 6-spd and adaptive M suspension is a joy to drive.

I can't think of a way it could be as underrated unless a different turbo setup is also part of the design.

Absolutely not.

An ///M(oron) representative did tell a member that the car used a different turbo than the 235. However, the next thing out of that person's mouth was to say the car was twin turbocharged.

So, given that they clearly had no idea what the hell they were talking about, you can't take the first statement with much weight at all.

We still don't know. And frankly, I'm shocked more people aren't asking the question.

Thanks for the clarification. It seems like we will be finding out this info soon enough though.

On a side note how is the M235i N55 turbo for longevity anyway?

Where can we get details about the specs on this car? It should all be out by now including the specifics of the engine parts used from the M3 that have been mentioned. I hope it's more than the letter M on the top.
