Just test drove the 2021 x40 and M50. I was sold on the M50
Until I drove it. Motor was noisy, jerky in low speed driving due to power and throttle mapping. The 40i struggles at high speed highway merging power but usually that’s not needed anyway. The mild hybrid start stop was also buttery smooth and very responsive. The 40i

I’d get the M50 just for ego (and IAS) but the day to day, 40i seems to be the ticket.

anyone else have a similar experience they want to share?

I would get an M60i in a heart beat (in fact been considering a trade just 4 weeks after getting a 23 40i), but I did find the parking lot speed throttle response of the M60i less smooth. Haven’t tested an M50

M50 sounds better than the M60 and definitely the 40i. This is coming from someone who has two EVs (and thus sound isn't a huge consideration for me). We also have an X7 40i and while it sounds ok most of the time, there are times it sounds a bit whiny. Surprised you would derogatorily characterize the the M50's motor as "noise."

The M60 has the mild hybrid integration that would likely help with the feeling I had. The M50 was just too sporty feeling for day to day city driving. Probably better for mountains and heavy loads / towing but those aren’t my use case.

It’s a valuable lesson that saved me at least $10k. Now to find an 40i that is reasonable and has the features I want.

Helpful tip: you can search the VIN under “my cars value” on KBB.com and it’ll pull up what packages the car has after inputting mileage and zip code. No email address needed. Super easy way to validate quickly if a model has what you’re looking for.

Very odd? I get nothing but smooth power at any speeds on my 2020 X7M50i. Drive mode will really change the experience as sport or sport+ is a neck snapping animal where “adaptive” is my smooth every day trip mode.

B58 is very underpowered for this car - it’s great for puttering around town but the moment you want to merge into the freeway or change lanes, pass cars that’s when you feel the heft and the struggling exhaust note from the B58 where the slightest squeeze of the throttle shoots up the rpms.

V8, is noticeably way more powerful and accelerates with a ferocity that seems to defy physics. It is also smoother - the rpm is around 1700 at 75mph. Like they say - No replacement for displacement - at least not at the 100k vehicle price tag.

I’d be all for the M50 but the motor noise was incessant compared to the 40i. It almost sounded like the noise was being piped into the speakers like it is on a Mustang eco boost motor. Super annoying. I want the X7 for the lush, quiet ride that is still sporty enough to super cruise at 90mph. The V8 had an abrupt on/off throttle when approaching a stop sight and moving slowly through the intersection. The 40 was glassy smooth.

Like you said, the 40i was using its power and RPM range but even at 70% power, it still appeared quieter than the M50. Weird stuff.


?? Can anyone confirm if the M Sport package on to 40 changes anything to the exhaust or is it all appearance and brake upgrades? I like the M sport steering wheel vs the larger round thing on standard 40.

The B58 isn't underpowered by any means. It has sufficient power to handle all situations you described. Highway merging and passing has never been a problem for me and I've never felt like the engine was struggling. You're correct that rpms go up, but I don't see it as a problem at all, especially because it is usually very temporary. Any gas engine has to increase rpms in order to produce more power.

Yes, the V8 is much more powerful and is fun to drive, but let's be honest: the X7 is a family hauler, and while it can definitely be fast, this is not why it is so popular on the market.

I have a 2021 X7 40i with the M Sport package. You're correct that it only changes the appearance, brakes (optionally, I don't think I have the upgraded brakes), wheels, seats and the steering wheel.

M-Sport brakes are a separate option, not part of the M package on your car.

So because a SUV is large equates it to a family people hauler?? So if you own a large house you also need to have a large family as well? Luxury by definition is getting more than you need.
There are lots cheaper and more fuel efficient people haulers for the money if that’s the main task.

I purchased my fully loaded X7M50i as THE best ride and handling full size luxury SUV made for cross country trips and roomy interior. I have done the full size German luxo sedans and they are still too small for real traveling for two adults.
Big, powerful and fast embodies the whole idea of what a luxury vehicle is and why a longer wheel base is a fundamental requirement for delivering a more luxurious ride.

I don't think that is the case. Take a look at the spec list below. Notice how it mentions the M steering wheel, but doesn't say anything about M brakes. I think the M sport brakes was a separate option back in 2021 and wasn't included in the M Sport package.

Yeah, that was a typo, I meant a separate option, not part of the m package. My bad.

I've only had my '21 M50i for a week and moving at slow speeds like around a parking lot or in my neighborhood has been pretty smooth overall. In comfort mode, the only thing that annoys me is on initial throttle at slow speeds, the engine response is a bit slow, car feels slightly sluggish and the engine sounds like it's cranking something. The feeling goes away the moment I hit a bigger street and start moving past 30mph. Otherwise, I give the gas a bit of a nudge and I'm humming along at <=20mph very smoothly.

I only test driven the '23 40i and it had plenty of power in my brief local/highway drive, the mild hybrid setup really gives it that EV-like low-end torque. The response felt peppier than my M50i but of course, once you punch it, M50i gets neck-snapping real quick.

On the pre-LCI M50 you can code in Comfort Plus mode which makes the throttle map incredibly smooth. It also affects transmission tuning, if you floor it in Comfort+ the car will go fast but will do it a lot more smoothly than usual.

You could also do that coding on a pre-LCI 40i, not sure if Comfort+ in 40i would be even smoother than Comfort+ in M50i.

iDrive should have an option to put fake engine noise in "reduced" mode. Not sure if the early 2019 cars have that option as well, I think it was added sometime after release? Anyway, you can code out the engine noise entirely on pre-LCI. But it may still be louder than a 40i, I'm not sure. The M50 definitely makes quite a bit of noise when driving around town (only when accelerating; it's completely silent at idle and when driving at constant speed).
