interesting... can you share your source?
this is what I have 2017 M240i xDrive Coupe Standard Features Performance and efficiency • 3.0-liter BMW M Performance TwinPower Turbo inline 6-cylinder, 24-valve 335-hp engine. Combines a twin-scroll turbocharger with variable valve control (Double-VANOS and Valvetronic) and high-precision direct injection |

http://www.2addicts.com/forums/showthread.php?t=1262859 I just looked at the sticky threads and compared the ones for the M235i versus M240i. Although as I write this I'm wondering if one number is SAE HP and the other is DIN HP. That could account for the discrepancy. |

Those who said you wouldn't feel the power difference are correct. 20hp and 39 tq won't be all to noticeable imo and the mpg difference is 1-3 in favor of the b58. Overall, wouldn't be worth the trade in from the 235 to the 240. However, if buying new, they're selling them both right now at the same price, only reason to go 235 would be impatience of waiting a couple months for the 240 to be delivered.

The M240 will certainly be a faster car than the M235. There's no getting around it's power advantage, especially on the topend of the powerband. Given that the heavier 340/440 cars have the same acceleration numbers as the M235 and that the M2 is not monumentally faster than the M235 (about .3-.5 seconds and 3-4mph faster in the 1/4 mile; depending on transmission), I do have to wonder if BMW is going to neuter some of the M240's acceleration potential to keep the newly introduced and highly rated M2 well ahead. When I look at the powerband shape of B58 and the fact that the M240 is around 100lbs lighter than the 340/440, I could certainly see the M240 being right on the heels of the M2. I mean, really close. We all know BMW underrates these turbo motors. The M235's N55 makes closer to 350hp/360tq at the crank and the B58 (non-MPPK) is making around 370hp/380tq. Assuming the M240 actually makes more power than the 340/440 because of the MPPK (like the M235 comes with, ie more boost/power), the M240 will be quite close. Perhaps BMW's indication that they're stretching out the gear ratios on the M240's 8AT is one way of neutering it's acceleration potential in comparison to the M2.
With all that said, the playing field completely levels with power mods and the sky is the limit. Neither motor is really better than the other as it's plenty easy to extract absurd amounts of power for cheap. At this point, the N55 is more tried and true and we still don't quite understand the B58's limitations, specifically the turbo and it's multiple turbo and IC water-based cooling systems. That's where I'm most worried about the B58, stock or modded. If the B58 turns out to be as reliable as the N55, I may consider a B58 2 series, a B58 M2 that is |

I agree Xutv, and I think the b58 will be as reliable as the n55. It's already hit the Forbes top 10 list within its first year and has raving reviews. The xDrive variant is supposed to be 4.2-4.3 0-60 times so the m2 is still faster and exact times haven't been released yet for the 240 so always room to wiggle from there. I think the next variant of the m2 will come with the b58 in it because the potential of the motor is there (already having the same torque as the m2 with overboost).
Gearing does play a huge roll in actual performance numbers though and that is where the m2 will always outshine the non m series vehicles. They're geared for the track and I'd expect them to put out better numbers. Almost ordered an m2 but the dealer told me it's an 18 month wait even though I'm stationed in Germany. By then I'll be back in the states so just went with the m240i. Plus the wife wanted the xDrive which the m2 doesn't have (yet). |

If a GC comes about I would strongly consider, particularly a m2 GC. If I were trading in Today I would be looking at a CPO m4 vs essentially the same car.

My lease ends in 2019 so if I don't get a m2 or a Porsche, then maybe.

I'm actually thinking about trading my 2014 RWD for a 2016 xDrive exec demo w 3k miles. Doing a higher mileage lease and it has some extra dodads would cost me $50 per month, not bad. Also would line me up timing wise for a M2 GC in 2020.

The only reason I bought M235i is N55 engine and its LONG way to finally becoming what I only hope is somewhat reliable engine. Could B58 be more reliable, sure, but so far BMW statistics prove otherwise |

The main thing that has me interested in the B58 motor is that it is supposed to be a little less carbony or sooty which could indicate going a little longer enjoying performance without having to do engine internal cleanup.

Check out this one user....
"I must have a different 340i/B58 than the one lavishly praised in the review. I've had my 2016 340i XDrive for four months and put close to 5K miles on it. It's my fourth 3 series in a row since 2003, all with turbo 6 cylinders, so I've put a lot of miles on the series over the years. The first sign of trouble was when the car was pulled from delivery for a recall - something to do with the fuel injectors - on its way to my dealer. I find the turbo lag and driving hesitation very noticeable and irritating, especially when recovering from a turn. The engine feels like its always minimizing itself (fuel economy?) and is sluggish and irritatingly slow to respond. It even shows this pattern in Sport mode. When I get on it, the car is fine but that's a small percentage of the actual driving time. Dealer says the car "is within specs" - the classic response. It may be that the engine is fine but the engine/tranny programming is poor. Hopefully there will be an update. At this point, I want the new car but with my old N55" Some F30 b58s already have bearings recall by the way.....same story with all new engines, you just have to pray that yours is covered lol. Sometimes BMW takes care of you like the case with E46 M3s, but E90/E92s are shit out of luck.... Last edited by Kolyan2k; 07-24-2016 at 06:33 PM.. |

only way I would switch from M235i to M240i is if BMW offered LSD as a port installed option. B58 and new ZF8-speed is really nice and butter smooth.
Love my M235i w/ LSD. |

For $299 just add the Dinan Sport tune and you have the same power as the M240 with a proven engine.

By the time I'm done modding the power difference won't be an issue.

Not this guy. If it were a body update, lights etc.. Maybe, but otherwise not worth the loss (if purchased).
Plus, I'd rather heel/toe the old fashioned way lol

It's a light version of their Stage 1 to compete with JB and others. Does not have Dinan 4 year matching warranty and functionality wise it's. It quite as good as Stage 1 either. They have all the details on the website not going to regurgitate it all here. Hope that helps.
