Should have waited. After market development will certainly start focusing on B58

You bought the car to drive, not to garage. So feel happy you have your M235i to play with while everyone else is spending months logging-into BMW manufacturing/shipping pages waiting for their 240i. Schedule a road trip in it, even if it's just a long Weekend. We ran our M235i Convertible in on a road trip 'round the Swiss Alps, which was memorable. There will always be a new model or modified spec' just 'round the corner.

Actually in another topic he mentioned not driving the car until spring comes. For that reason I think he should've waited. Prices will definitely be lower 6 months from now for used m235i since many will be getting their m240 and dumping the previous car.

He paid $44k CDN for an M235 w/ under 10k kms, fully loaded 6spd. Why on earth would anyone spend $57k CDN (pre tax/delivery fees) on an M240 (that's what an equivalent M240 model would cost, or new m235 as well for that matter), just to have a newer engine? I can tell you that the B58 is not worth $14k and depreciation that follows a new car purchase, let alone the fact that it is a new motor, with limited performance options (tested long term) as of today.

That's just back to the old argument of why buy a brand new car at all. The true comparison is really a new 240 vs a leftover new 235.

At least when looking at leases in Sept the 235 residuals were much higher. That combined with a bigger discount on the car to begin with amounted to huge savings.

I never mentioned getting an M240. If you read my post carefully you'll see that I said M235i prices will be lowered 6 months from now. There's no point getting that car for $44k CAD and storing it for 6 months when he could get the same car cheaper 6 months from now when he actually starts using the car and people might start dumping theirs to get a new M240i.

And you can get a M240i (pre tax/delivery fees) for $52k CAD, not $57k.

That is an old man's tale, and was a prevailing wisdom from way back in the days when doing and actual engine "break in" actually accomplished something.
The current modern world has put that old man's tale to rest.

Just so you know, I'm 51 and I remember those days way back when.
I also understand that modern engine design and construction is vastly superior to those days gone by.

A first year engine does not mean that engine was designed, built, and tested within that year only, and thus it's a "baby". It takes time to develop, engineer, and test upcoming auto technology and that includes engines.
The B58 isn't any more prone to problems than the relatively young N55 engine. I remember when the N55 came out just a few years back. All the N54 fans were leery of the N55 and warned about how it's still new and that no should ever buy a car or engine in it's first year. Yeah, ok.
If everyone were to abide by that silly advice, then that could cause the manufacture to wonder if they should still build that engine or car due to no sales in the first year.

More importantly, the N54 has more issues during it's lifetime than the N55 did, namely the HPFP. I had a 135i with N54. Luckily my HPFP never gave out, but I did have symptoms of potential approaching issues. BMW came out with the final HPFP that solved the issue and my 135i was fitted with the new pump. I had that 135i for about another year and then got a 2013 335i with the N55. I now have a 2016 340i with the B58.
Other than the odd cold start shaky idle, that lasts for about 20-30 seconds, the B58 is an AWESOME engine, just as the N54 was and just as the N55 was.

To anyone considering a new first year car or engine, don't sweat it.
BMW makes excellent engines, and they really do step up when issues become apparent. Yes, sometimes it can take a while for them to figure out the problem and get the actual correction, but they do take it much more seriously than other companies in my 36 years of owning and driving automobiles.

Now, there is something to be said of the potential of greater overall issues regarding a new model, such as when the F30 first came out.
Naturally, the potential to have fitment issues is greater on first run cars, but most of those things are fitment related such trim not seating correctly, or other minor things that need adjustment and/or potential assembly line adjustments and modifications. That's all part of continuing to improve overall quality of a product.
However, in regards to the major components of any automobile, such as engines or transmissions, those items get much more extensive testing and consideration with low potential for "first year" problems.

To the OP, the N55 engine is/was an excellent BMW engine.
Other than having a bit less power overall you're still getting a fantastic and excellent performing engine.
In regards to other differences besides the engine and likely the ZF 8spd AT, I don't know and thus can't comment on if the overall M240i is better than the M235i.

I can compare my 335i Msport AT to my 340i Msport AT.
BMW nicely improved most of the things that owners and the press complained about in the original F30, namely the steering, suspension, and overall handling. My 340i is a noticeable improvement over my 335i in regards to steering feel, ride, and overall handling.
Also, there is a noticeable difference between the performance of the N55 w/ZF AT and the B58 w/ZF AT. The B58 is noticeably more powerful than the N55, and it actually likes going to red line more so as I can feel how the B58 keeps pulling beyond the RPM where the N55's power drops off.
Also, there were improvements made to the ZF AT that result in a bit smoother and crisper shifts, with more responsiveness when a downshift is needed. Overall, the ZF AT was great to begin with, so the improvements made for the 340i are subtle.

no it hasnt. Look up the huge number issues with 2007 N54 engines vs later ones. The least not having an oil cooler for manual cars.

Not with the options he got with his car. It's a fully loaded model, well over $55k CDN, before taxes/allocation fees. Regardless of the M240 release, you won't get a better deal, with more warranty than new, like he did. That's all I'm saying..

[p912guy]

No regrets here. I just purchased my M235i Convertible a few days ago and I am thrilled. The only thing I missed in not ordering a new M240i over the M235i that I purchased off the dealer's lot was the opportunity to pick my preferred color combinations. The extra HP and torque mean nothing to me as a DD. Also, if I had ordered, my wife would have preferred the AT (happy wife - happy life) and I am really happy with the 6 spd. So all's good. Now I just need to wait for my winter wheels and tires from Tire Rack to show up and I'll be ready to start driving my early Xmas present. There's no way I could just let it sit in the garage til the weather gets nice.

So I'm an old man. Guilty as charged. I'll stand by my statement and if BMW didn't think a break in period was necessary they wouldn't recommend 1200 miles to do just that.

We can't say that for certain as the motor has only been out since 2015 and incorporates a whole host of new tech like a fluid-filled intake manifold/intercooler, a turbo cooling pump, an additional mechanical cooling pump for the intercooler, and a rear mounted timing chain.

The N55 on the other hand, has been out for quite a while now and overall, is a fairly reliable motor, especially in comparison to the N54. The N55 is more simple and overall, less complex than the N54. Numerous articles noted that the N54 was a bit of a rush job by BMW and they paid dearly for under-engineering some of it's complex systems.

The B58 is certainly a better motor from a power and efficiency standpoint, but it's also a far more complex motor than the N55. The addition of liquid-filled IC and two extra cooling systems teamed BMW's poor reliability history with its cooling systems doesn't sit well with most of us nor does the rear mounted timing chain (another design BMW has a poor history with). Potential repairs in the B58 appear to be higher than that of the N55. I do hope the B58 turns out to be a reliable motor because I'd like to consider it in the next gen 2 series coupe.

[Dylan86]

^^ Well said, and wholeheartedly agree. The N55 is great, the B58 is great. Which is better long term? Let's find out
