M have done a little bit of fettling, surely? It can't just be engine & exhaust..
There are some other differences but in character its much closer to a standard G20 than the G80. EG the LSD is standard, stiffer suspension, wheel camber adjustment and I think perhaps slightly uprated brakes. It also rides slightly lower.
I managed to clock 150 odd mixed miles in mine yesterday so thought I would jot down some background initial impresssions for those that might be interested in this model.
I am coming from just under 6 years and 85k miles in an F36 430d so that is my easiest point of comparison. It was a very capable car and had given me no trouble over the time I owned it, however it was starting to show its age a bit and I fancied a change. I did briefly consider going Tesla Model 3 but my business partner runs one and the time I had in it left me cold and he is still far more likely to hop into the ageing SLK55 he also runs. As a bit of a BMW fanboy the similar offerings from Merc (c43) and Audi (S4) were again briefly looked at but soon dismissed. If the S4 were still available as a petrol then maybe it would have had more of a chance.
I had actually factory ordered a very similar M340i in November 2019, but having still not received it by March 2020 and with lockdown landing I had the option to walk away from it at no cost which I took, given the uncertainty about the economic impact and travel restrictions. That turned out to be a decent move as I clocked less than 2k miles between March last year and 2021. I continued to watch the market though and as I work in an industry that turned out to be quite important during an worldwide pandemic no economic disaster landed at my door. I recently decided should I see an opportunity to get into one at an acceptable price I would take it. In the intervening months the model year changes and subsequent price hikes, coupled with the significant delays meant a new factory order was not that appealing. BMWs contributions in Q1 at least are also much lower than they had been on my original order where I had got to 20% off list. This led to me watching for stock cars, whether new or nearly new that met or exceeded my spec requirements whilst still keeping close to my original price point. Eventually the car I ended up buying surfaced, it being 5 months old and with 3k on the clock it was offered at 25% below original list. Not deal of the century, but within my acceptable range and with plenty of warranty left to run. Most importantly, it was a pretty special spec and I had seen nothing similar come up at that price. I did also consider the touring which I think look nice and are obviously more practical, but my wife vetoed it on the grounds that we aren't old enough for an estate(I'm in my 40s, surely prime estate age?!)
On to the car itself. The exterior is pretty non-descript and for most people would be indisguishable from any other G20. This suits me perfectly as I am happy to run under the radar. Dravit grey is very flat when there is no sun, it comes to life under bright sunlight or lights with gold/bronze touches.The cerium grey touches look awful in pictures but suit the car in this colour very well. They do not stand out and in fact complement it quite well. The grille when first introduced looked quite controversial but compared to the G22 and G80/2 it looks positively normal. My wife's first comment when I brought it home was 'like the grille, love the colour' and she is notoriously fussy so I can confirm that combo is wife friendly! I'm not a fan of black wheels so non-shadowline was a must for me. I am not bothered by the semi fake exhaust tips, I actually think they look pretty decent but I appreciate it's not everyones cup of tea.
The interior is a significant step up from the F series 3 and 4s. The driver's cockpit area feels moulded around you and you immediately get the sense you are in a bigger car. Going from the F36 where the driving position was styled after the coupe you do sit higher up in the 3 series. The build quality and finish is noticeably better than in my older car and it does feel more premium. There were no rattles or squeaks that I could detect, not even from the sunroof which is an often-reported issue on this model. The controls a well laid out although I already miss the thing that altered the hot/cold air mix. Also I feel the stalks for indicators and particularly the wipers are a step back but are fine in reality, its just a shame as the soft touch ones in the F36 were perfect. The digital cockpit is...well its crap. It's overly fussy and I struggled to quickly get the information I wanted from it. This may improve over time and as I configure it a bit more but I'm tempted to turn everything except the essentials off. Thankfully the HUD is brilliant, very clear and positioned well so you never have to take your eyes off the road. The touchscreen display is clear and easy to reach although by habit I still use the wheel. Gesture control is a gimmick but the kids thought it was cool. On the subject of the kids, I have a 9 and a 12 year old and they were quite pleased with the extra space in the back. This is a combination of more legroom but also since its the saloon it doesnt suffer from the sloping roof of the Gran Coupe.
On driving, I managed a mixture of different roads across motorways/dual carriageway, A and B roads as well as through town. I can best sum the experience up as 'effortless'. It is not an aggressive car, even in Sport and with foot planted it is so smooth. If you are looking for an event each time you get in your car, pick something else. Obvoiusly if you push it hard you can have it moving around but in every day use it is extremely smooth. It is of course pretty quick,I am yet to launch it but it picks up quickly and pushes you a bit into your seat. It is very easy to be over the speed limit before you know it. There is a little bit of turbo/gearbox lag in comfort depending on the circumstances. The engine is a peach as I think everyone knows and has a reasonable soundtrack, although some of that is piped in and it is quite muted so again if you want something that roars you probably need to look elsewhere (or mod it). My kids immediately picked up on the reduction in wind noise/tyre roar in the cabin compared to the previous car, although the F series was notoriously bad for that. It's definitely an improvement. The suspension is quite stiff although its fine in comfort. Steering is overly heavy in sport as seems to be standard for non-M BMWs
I had a bit of a play with the driving assistance stuff as well. The lane depature intervention I initially thought was OK, but it did try to fight me a couple times and made me nervous enough I've turned it off for now. I suspect this might be about adjusting driving style as much as the system being overly aggresive but we will see. I have left the lane departure warning rumble on though as that seems to be quite useful. Adaptive cruise worked well, as did the driving assistance and it kept to the road very well. The fact you have to keep your hands on the steering wheel, whilst I understand why, does render it a little pointless though! Speed limit detection worked very well even in some temporary roadworks it detected the signage correctly. It's nice it gives you the option to hit the Set button and adjust the speed automatically although it slows the car quite quickly, not in the way people would naturally bleed off speed when changing between zones. Just something to watch out for particularly if you are in tight traffic. I LOVE the blind spot detection, what a brilliant system and so simple. The lane display in the cockpit is also quite cool although I've not yet figured out how to get it to change lane automatically (based on an indicator push I thought?). There is still no substitute for actually looking around and in your mirrors though.
I am yet to play with the parking stuff other than the basic detection I used when I got home. I'm not sure how much I would use this anyway although the cameras are quite handy and the fact they can double up as kind of dashcam in case of an accident seems useful. I have also not used any of the connected apps but will be going through some setup today to see what there is. Frankly the amount of tech embedded is slightly intimidating and I suspect it will be several weeks before I've worked my way through it all.
One last thing, whilst picking it up I did see both a G22 and G80 in the flesh. The grilles are not as bad in person as they look in pictures. If that's all thats turning you off I'd suggest going to have a look as you might find you are actually OK with it. The G80 in particular looked epic in Brooklyn Grey, but too rich for my pocket and definitely not a subtle motor. The G22 front looks much better with a UK plate on it but is still not great in my opinion.
Well that's it, if there's any questions anyone might have I'd be happy to do my best to answer.
