This is the BMW X3, but it’s packing the legendary B58 straight 6 under the hood which makes it the M40 version. And while we’ve had experience with the previous car, this is the LCi or facelifted version - so is it still the best sporty compact SUV on sale? That’s what we’re here to find out
And how could we not start with the beating heart, the B58 from BMW
However, there’s a difference between this one and the pre-facelifted version
THIS B58 is now packing a 48V mild hybrid system
That 48V system itself is good for 11 hp, but it’s not exactly intended to boost performance much on its own. The system is intended to take load off the engine by running onboard electronics etc. This allows the engine to better turn its explosions into speed. Interestingly enough, the addition of the 48V system doesn’t alter the 382 hp and 369 lbft claim from the last X3
But here’s the thing. We all know this engine is underrated
It’s making more like 420 hp
AND the 48V system DOES do helpful things like smooth out start/stop and gear changes from the ZF 8 speed transmission
What t results in is 0-60 in just about 4 seconds flat…pretty impressive
There’s no surprise this X3 M40 is quick but as a sports SUV from BMW there’s also an expectation that it can get around corners…
And, no surprise here, it goesa round corners very well
I mean, not as well as a coupe or sedan, but in terms of sport SUVs, behind the wheel this shares a place at the top of the heap with company like the Porsche MAcan GTS
It’s got adaptive suspension
It’s got a nice and progressive steering feel
And it’s got a LSD on the back
I mean even in these wintery February conditions this thing is really rewarding to push hard
HOWEVER, this X3 in M40 guise has been accused in the past of being too narrowly focused on sporting performance and doesn’t split the personality enough to deliver a luxury-level ride…So does that still ring true for this facelifted model?
To address this we have to think about things in relative terms
With the raised ride height of an SUV
And with a highler roofline there’s more weight higher up
And what that results in is the suspension needing to be stiffer to deliver the sporting performance
And yes, this X3 has adaptive suspension, but even dialed back the dampers remain a little stiffer than you’d have in the 4 cylinder X3
But again, you bought an X3 with an M badge on it so you could have seen that coming
And in truth, while the ride isn’t a floaty luxury boat, it’s still pretty comfy even on these terrible West Allis roads

[@mikedot2260]

M40i is a beast. No better performance at that value in that class.

[@dwnshft]

100%

[@Investor9872]

I've watched hundreds of X3 M40i reviews, and this is the first one on 19" tires discussing comfort and quietness. Thanks.

[@dwnshft]

glad it was helpful🙏

[@w17force1]

I have the 19" tires on my 2021 X3 M40i. Test drove both (21" vs 19") and definitely preferred the smaller tires. They don't look quite as sharp as the 21" tires but are worth the upgrade for comfort IMHO.

[@pgrech2]

I have the 20" and rpelaced teh run flats with regular Continental extremecontact DWS06 and it transformed the ride.

[@charliethesupebeagle]

I went down to 18 inch with DWS 06+. So much better with more sidewall. Technically out of spec but lots of clearance.

[@bxp1696]

@@w17force1 I have 20' and the ride on 20 is also good. I did not want the stiff ride on the 21 wheels. It may be okay for some but I considered the roads where I live and long term comfort.

[@kyler7325]

Completely agree the little suv is amazing. It has plenty of power and drives more than a sports car than a luxury SUV. Did you know that with the red interior you can’t get the cooled seats? That’s why that car doesn’t have them. Only thing I’ve noticed so far is the stereo system could use some help. And additional woofer somewhere in the back would do wonders. Other wise petty well perfect. Can’t thank Mike and the guys at international enough. And thank you for the great video !

[@dwnshft]

it's a great car! I did not know about the red interior; interesting!

[@miata1370]

This is nearly an identical M40i to the one we will be picking up in Greer at the Performance Center next month. Alpine White over Tacora Red Sensatec with the carbon fibre trim; but non-shadowline. I really appreciate seeing that tacora sensatec/carbon fibre interior! I totally agree with you on the benefits of iDrive 7 that retains the functional buttons now buried in the multi-level iDrive 8. One more reason we purchased this 2023 vrs the upcoming refresh. Thanks for posting!

[@pgrech2]

Agree 100%, love my x3 m40i.

[@chadbobby]

UMMMM. FOR SURE "Bother" with the full M version!!!! I have the X3M Comp and its WORTH it for sure!

[@jonasbaine3538]

Did you change springs for better ride quality?

[@johnevans6474]

I just love my X3 M40d, it the nicest vehicle I’ve ever owned with all the performance you’ll ever need. Don’t forget to spec “adaptive suspension “ for UK driving.

Purchased my 2024 X3 M40i three weeks ago and love it. I thought I would miss my 2016 435ix grand coupe, but I don’t :)

[@jsupreme369]

I have the 2018 X3 M40i. I've had it for 5 years now. I test drove the X6M Competition at the BMW Exclusive AutoCross and it's a must that I get the X3M Competition. What a machine!

[@mspeed2441]

So, I have an X3M Comp and my mom has an X3 M40. The one I would skip is the X3M non-comp. If you're going to have the stiff ride of the M, you may as well get the real S58 (mine dyno'd at 545bhp), not the detuned one. I love the ride of the X3 M40, but my X3MC destroys it. That said, the speed of the Comp can sneak up on you so quickly, you have to be on your game. And, it will scare the hell out of your passengers...something about being higher up.

[@dezrok1]

Great review! Just took delivery of 2023 X3 M40i in Brooklyn Grey and tecora red seats. I'm loving the sound, drive, style and the fun. Wish there was a subwoofer in the back!

[@alfredosantaolalla]

It's really missing one!

[@pej7445]

I have a 2019 m40i with about 51k miles on it. It's been the best, most reliable, fun car I've ever owned. I'm considering upgrading to a 2023 before they stop making them. They want a lot of $$ to move up 4 years, so I may just wait and buy a used 2023 in a couple of years.

[@trishonya]

I have a 2019 m40i with 88k miles on it and it’s amazing but just make sure they check your motor mounts and I have a coolant leak but I still have a extended warranty so it’s covered!

[@edwindavidson6285]

Got the real (S58) M and am glad I did. That roar under heavy throttle was worth the price

[@Dapster8888]

I’m with you on this one. I had a 2019 M40i for a year and traded in for a 2020 X3M Competition which I have now had for 2 years. Full fat and head turning roar when accelerating....

[@Snaproll47518]

I took delivery of my '23 M40i in December, my third BMW since 2011, and it's a blast to drive on the winding country roads where I live. I was surprised to get 30.9 mpg while averaging 78mph on a long trip. My only negative is there is no tach display on the HUD. For potential buyers: I made the mistake of not upgrading to the Harmon-Kardon speakers. The standard speaker is a bit lame.

[@baoquoc3710]

Usually, standard options on BMWs are some parts bin class or just the minimum amount of technology (5 years old techs I suppose)

[@chrispederson4157]

You cab add in menu not a tach but line graph for rpms in are 22 x6 40i that works good.

[@alfredosantaolalla]

The HK system is not that good either. The Jeep's alpine system blows it away so bad.

[@debdixon6272]

Love it!

[@preoksaha4504]

Have a base 30i and it still does 0-60 in 5.5s. I can only imagine how amazing the m40i feels! One day baby!!

[@Mr.Lambert777]

U will love the m40i. I love mine. I got it build in last December as a 23 model. super nice

[@germanengineering204]

Upgrade, and you will be blown away with the performance difference!

[@w17force1]

I test-drove both cars back in 2021. I MUCH preferred the M40i version's performance and bought one for about $12K more. Recommend the 19" rims for comfort.

[@alfredosantaolalla]

It's extremely addictive, first drive you will be shaking lol

[@gbrianjohnson]

I have the 2018 X3 M40I and its older and does not have the mild hybrid but I have added a Carbahn Tune so now its running close to 450 HP and 445 Lb Ft. Makes the need for a proper M car not as prominent. The new LCI looks good. Perhaps when mine is up there on miles in a few years I will pick up a 2023 used X3 M40I

[@dwnshft]

the 2018 was the first X3 M40 i drove and it was such a big step up - really nice car

[@barbararomero2350]

[@ahkeen]

The godly B58!!!

[@xellium5445]

I own a 2020 pre LCI and that includes the same B58Tu and mild hybrid system as the LCI facelifted models. Mine sits on the bigger wheels, but the ride quality with them is an absolute pain, and there has been an occasion or so where i’ve taken out a wheel just due to the lack of sidewall combined with rural Oklahoma roads.

[@dwnshft]

oh man that's rough! so are you not enjoying the car overall?

[@michaeldzema4272]

Have a 2019 and I love it

[@allanchen8496]

If you get this new LCI M40i, please spec bigger rims. It gives you a wider section tire (275s) versus the 245 sections pictured in the review.

[@miata1370]

We chose the 19" wheels...no additional cost and offer a square tire (verses staggered) setup making tire rotations possible. Those 19's will likely become my winter wheels next season; 19's better for winter with their corresponding narrower tires. To each their own....I'll have a universe of additional aftermarket wheel options for the "summer wheels".

I think the 22 and 23 are the best model years with iDrive 7. I tried out iDrive 8 but hated the less physical buttons and more glare under the sun. I’m guessing the next gen BMW will not put in B58 and will go with 4 cylinder only like what Mercedes does with its GLC.

[@miata1370]

I totally agree...a prime motivator for us in ordering the 2023 M40i. Burying controls within the multi-level infotainment screen is to me, a hazardous trend in interior auto design...but hey, I'm an old guy! 🤣

I have this beast. Fantastic, but I agree the ride quality is stiff, but still acceptable. We don't talk about mpg with B58 under the hood lol. And in European roads, I feel no luxury rides with this thing. Having said that, it's still an enjoyable car that makes you smile every day.

I went from a 2019 Audi A6 to 24 X3 M40i and absolutely love the X3. I thought I was going to get less tech for some reason but X3 with Prem and Park Dist control has MORE tech than the A6 (even the 2024 A6). For example, the 360 camera view offers more information than in the Audi. I highly recommend the X3 M40i.

[@lightbender1701]

Great Review! I just took possession of one with 20" wheels. The ride is excellent! Way, far better than some of the reviews (not this one!) might lead one to believe. I've driven sports cars for decades, and this is just about stinking perfect. It's faster than snot, corners like a dream and even my wife thinks its a comfy ride. People who think these vehicles ride "hard" should get a Caddy. Or maybe just stay at home, sitting on their Lazy Boy playing video games. 😁

[@yournewlowrate]

an added volt hybrid system give the vehicle more torque too. Personally I think the added volt hybrid system is just another expense down the line. My moms jeep wrangler has a volt hybrid system and it's peppy too, but its not a real jeep. My mom doesn't off-road, she just likes her cute jeep. I'm sure many customers like to be cute and feel like they are getting performance too by paying an extra $11K for a little electric motor that is gimmicky.

[@thetorment0r]

I'm leasing a 2023 X3M Competition and I've been wondering if the extra horsepower was worth the extra 15 grand, thinking about switching over to a X3 M40i when my lease is up and saving like $250 a month

[@Mr.Lambert777]

I am leasing the 23 x3M40i, with the sports diff, yoko summer tires. I guess it all depends on rather or not you use all that power daily. I think it’s making more than what bmw states for both our cars. I want the M3 lol,so the question is , is it worth the extra money?

[@nbidi5353]

Why did they make the center console black with the red interior for this year! That kills it, they should have just stuck with all red

[@dwnshft]

thanks! TBH if I had Macan GTS money I would go Macan GTS no question. The Macan has a higher performance ceiling, but you make tradeoffs in places like rear seat space and trunk space so as long as you're fine with that then i'd lean GTS

We own a 2020 X3 M40i(wife’s) and a 2022 X3MC(mine). While the M40i is a great car and plenty fast, it isn’t a M. The X3MC is basically a M3 SUV. It is way, way faster than the M40i and handle like a M3. Also, the Merino leather interior blows away the cheaper Vernasco leather.
