These are my first impressions after driving my M340i for a few days now, and how it compares to the 2017 340i with MPPK that was my DD for the past 2 years. I will not be breaking any news by stating that the new car is superior to the F30, but one thing that surprised me is how tame the M340i exhaust sounds, compared to the M performance exhaust on the old car. In sports mode, there are the expected burbles and pops, but quieter by a few decibels, not as loud or violent as my old car, a bit of a let down. As for power though, the G20 power increase is certainly noticeable, the F30 was no slouch, and at no time did I feel like I needed more power, but the M340i is a rocket ship. Even in comfort mode, a slight flex of my right foot and the car just leap towards the horizon with an eagerness that is just incredible. This car make the M3 overkill, except for people who take their cars to racetrack. I won't get into how much better the interior of the new car is, it is night and day better than the F30, but I have a couple of gripes. The seats are very comfortable, but having recently sat in a Genesis G70, with soft, perforated leather, I realize that the leather in the BMW is not as nice. Also, I love the look and feel of BMW's new steering wheel, perfect size and heft, but wish the side grip was a softer perforated leather. All in all, the improvements over the F30 are quite significant, but I guess it will never be perfect. One last thing I've noticed with the G20, after about 30 minutes of driving, the G20 fan stays on for quite a few minutes after the car is turned off, not a negative, but I never noticed that with the F30

I have had mine about 10 days, I love it . Only 500 miles so not pushing it yet but it is quick!

I have had mine 4 days now, power is more than adequate for a street car. Just need to break it in asap so i can drive in Sport individual daily. Exhaust gets better with break-in or so I have heard which makes sense.

Exhaust in Sport+ is louder than Sport. Not sure what the mechanical difference is, but Sport+ is loud IMO for an M-Performance car.

Soft leather quickly begins to show wrinkles and wear, even when you are regimented with your leather care routine. This is not a positive in my opinion. I much prefer firm leather that very slowly breaks-in and that will stay looking brand new indefinitely with a proper care routine.

Exhaust will also become noticeably louder in Comfort mode when you hit DSC off and move gear lever from D to S.

md,
I hope you do, and will enjoy it. Did you get your car off the lot or order, and if you did order, how long did it take to get here? I have one coming, and I don't remember how long it took for my '16 340. FWIW, my back fence is the SR city limit.

Took about 8 weeks from production to delivery, as I live in California. Minus 2 weeks if you are on east coast.

perfect length review!

not so sure youll still have the genesis leather view when you see one with years of use, it will be all saggy and wrinkly whereas the bmw will still be firm

I disagree. Lot's of cars have perforated leather that last a long time. In fact, BMW has it available on the 5 series and above. Every car that offers ventilated seats have perforated leather. I think it's just that BMW doesn't want the extra cost on the 3 series, nothing to do with the leather getting saggy over time

I don't think he is comparing perforated vs non perforated. he is comparing soft vs harder leather.

Well, the Napa leather on my M3 was perfect after 4 years.

I was told these engines are already broken in no such thing as break in period by my CA. Asked a few people and they said the same. I put it into sport + and have been enjoying it with no limits. Let's see what happens

[TheObviousChild]

This is great to hear. I'm currently in a 2016 340 w/ MPPSK and have wondered how the power difference would feel. I'm also coming from a 6MT so I imagine it will feel even faster with the 8AT.

[Gdiddy23]

There should be a MPE version coming soon for the G20 M340i if I'm not mistaken. Will hopefully make up for the lack of sound you're experiencing.

[EXE46]

Read the user-manual and stop spreading propaganda. M340i has a break-in period, it's even mentioned to reference when launch control can be utilized. Why then ask an SA when the user-manual clearly covers that agenda.

I've watched a documentary recently on the Munich factory where this car is built. There is a track near the factory where they take the car on a single hot-lap to discover any potential mechanical faults or leaks caused during factory assembly. The break-in period should still be observes set all the gasket/sealing points, to allow the cams/lobes/springs to settle, to allow the cylinder wall linings to wear evenly, to allow all of rubber/metallic hosing between turbos and radiators to seat at their connections points and to allow the entire engine as a whole to settle through multiple hot/cold cycles. I simply do not understand why someone can't chill out for a thousand miles to allow the process.

Thanks for that

This is almost exactly what I was looking for. I'm hearing nothing but praise for the M340i and already in love w/ the B58. I currently have a '17 340 w/ 6MT, rwd, & MPPSK which I will be turning in soon. The other day my wife and I went for a quick spin in a '20 M340xi, no rwd cars on the lot. Nothing can be done about losing the 6MT but the exhaust was way too quiet even in sport. Have to try it out again as I read in another thread that sport+ sounds better (exhaust sounds the same in sport and sport+ on the F30). This is just personal, but the interior will take me a lil bit to get used to and that's just from being in an F30 for the past 6yrs. I surprised myself in that even on the short test drive, I found myself using the touch screen which was kinda nice.

To add onto what you said, I have picked up my last 2 cars at the Performance Center. They also give the tires as being one of the reasons for the break-in period. I was always told 1,200 miles. From the PC to home is about 1,000 so it's nice to get most of it out the way in one shot.

What did the car's manual say?

Tires break in after ~ 300 miles.
