My first and definitely not last. I'm 6'1" 225 and this fits me well. I also have back issues that I do not experience at all in this vehicle. I looked at all the competitors in this class and for me the BMW won because of the 6 cylinder, the space for rear passengers, and wow is it fun to drive.

My previous ride was a 2019 BMW X5 40i and I thought it was the best of the best. Then I decided to trade it due to high mileage and I ordered a 2021 BMW X3M40i. OMG!!!! What a boost in power and handling. I had to rethink my driving. This suv is not for the inexperienced driver. I ordered the M-differential and the M-sport suspension with 20" tires. It came with Bridgestone Alenza 001 RFT's and wow do they ever corner. They came with a speed rating of 168mph since my new suv now had a speed limiter preset at 155mph. The speed limiter was raised from 130 to 155 due to the summer performance tires that had the speed rating of 168mph. Had I ordered the 19" all weather tires, the speed limiter would have been preset at 130mph. My X3M40i is Glacier Silver Metallic exterior with Cognac leather seats and I also opted for red brake calipers instead of the standard blue calipers. I've had lots of fun with other people pulling alongside of me and getting me to race them. The look on their faces when my suv blows past them. This X3M40 is a rocket on steroids. With the M-sport suspension on it, I have gone hard into corners and felt it somewhat squat as I exited the corner at a higher rate of speed. No leaning and no body roll. However, due to this suspension, it has a very firm ride and that is fine with me. I recently took it on a trip to Wyoming and got 29.8mpg on it at 74mph. I had it on the ECO mode. The speed limit in Wyoming is 80mph and it had plenty of power at that speed. I've already decided to buy another one in a few years. UPDATE: This suv is on steroids. It is very fun to drive and is known as a sleeper. It doesn't look fast but I've yet to lose a race. It handles as well as it performs too due to having a sport suspension along with the M-differential and Michelin all-weather non-runflat z-rated tires. With all the power this suv has, one would not believe the gas mileage it can get. I set my cruise at 75mph on a trip from Indiana to Wyoming last summer and I got 29.8mpg overall. Not bad for having a high-performance vehicle that is capable of top speeds of 155mph. Currently I have about 28k miles on it. Seats are comfy. The ride was quite firm until I replaced the runflats with non-runflats. I've now got 72k miles and they've all been wonderful. No problems at all. I do oil changes every 11k miles and on my 2nd set of tires. I got rid of the runflats and installed Michelin all-weather tires z-rated for 186mph. I've learned to over-inflate my tires about 2-3psi. My best gas mileage is 34.7mpg at 70mph on ECO-mode on cruise. Hard to believe I got this on a performance motor. Currently, I am waiting on my next one to arrive. I ordered another X3M40i. It is mostly the same except it is a mild hybrid and white exterior with cranberry red interior, black wheels, and red calipers.

M40 X3 Just about perfect, all-around fun & more..

This makes my 9th. BMW since 1972. I traded a 2019 Porsche Macan GTS for this car. That says a lot. The 2021 X3 M40 has a great & powerful straight 6 that is simply magic. It tools around town but can transform into a brilliant sports hatch w/ a simple click of a switch. Build quality is excellent and I get 31MPG on the highway ( No Porsche Macan in the world comes close.) I wanted a smaller SUV w/o giving up my love a performance cars and this fits the bill perfectly. Do get the $700 optional adaptive suspension as it lets you choose between 5 different settings that will please the driver (all out sport mode for me) and family too. This puts a smile on your face w/ an exhaust note that is deep & throaty when asked to perform. I have driven the 4 cylinder model and honestly the M40 so much more planted that it seems like a different car. The M40 is hands up the best car in this class UNLESS you have $120K spend on the Macan Turbo. The M40 is still more fun. I grin every time I start it up!
