Drove them back to back in the dealership. Went in to try the X3 M40i, but sales guy had me drive the new X5 immediately after getting out.

X3 Notes: Exhaust sounds awesome. Exterior looks great. Way less feminine than previous x3's. Interior is pretty good, but materials feel a little cheap. Lots of power and fun in both straight line and corners. And did I mention the exhaust sounds awesome? $65k for the way I would spec feels like a lot to pay for an essentially $40k car with added options.

X5 Notes: As soon as I got in, wow. Just wow. Miles ahead of the X3. It feels special and very expensive. Glass controls immediately caught my attention. As did the dual digital screens. Feels 5 years newer than the X3. Lacked the noticeable exhaust blips and whurrs, but still felt plenty powerful! I read later that the as tested 0-60 is 4.9 even for the 40i (https://www.caranddriver.com/bmw/x5). The sales guy told me to go around a corner without letting off the gas. I tried but couldn't help lifting. He said "No way, you have to do it again and don't lift this time!" So I did it again. The X5 just squatted down through the apex and then shot out of the corner. I was hooked.

Conclusion: X3 exhaust or X5 everything else? The X5 40i with M Sport package, for the extra $4k, feels like twice the vehicle. Easy decision!

Hopefully the X5 with the Sports Exhaust = for the all-encompassing win.

Agree. Hopefully with just a little help from Dinan or MPPK or Racechip the 40i will be on par with the X3 M40i performance-wise. From a comfort, luxury, technology point of view it is already miles ahead

Looks like for MY2020 all bmw are getting new revision of B58 engine. X5 40 included
https://www.bmwblog.com/2018/10/31/b...88-horsepower/

It has 2 power levels so most will get lower 335 including x5 and even 840 (???)

The only ones getting 382 are m340 and z4 m40. And supra from toyota/bmw baby.

So starting july 2019

MY2020 x5 40. New engine. Same power 335
MY2020 x5 m50 new engine. More power 523

2020 seems to be big year for BMW. All models are getting serious updates in July 2019.

Anyone knows what is happening to X3 m40? thats the only one that has no confirmation on engine power? downgrade to 335HP based on particle filter and new engine? or upgrade to 382HP? along with M340

All I heard

G01 X3 and G02 X4 will be getting the new dash next year for MY2020. That's also when we'll see the hybrid X3 xDrive30e with the same motor as the upcoming G20 330e, uprated to 275hp

the X5 M50i isn't going to be the same as the regular 50i in terms of suspension tuning which is very important if you called ride comfort. The engine ratings are useless since BMWs numbers are never accurate since their engines almost always output more power when tested

Almost bought the M40i but after experiencing the X5 40i , the X3 interior feels as dated as my X4, its night and day. Waiting for my 2020 after bugs have been ironed out,

My wife and I drove both back to back and I went in thinking that's the one we were going to come out with. One of our chief requirements is towing capacity, it has to be able to tow my track car several weekends a year while still being a daily that my wife loves.

The X3 was just plain fast, like even faster than my 340i, and a hoot to drive with zero compromises in ride or handling for being a SUV. The interior was very nice as well. While I do tend to like louder exhausts the burbles and pops off throttle were a bit much. Its towing capacity was just a tiny bit above what I need (4,000lb) without much safety buffer, not a deal breaker but we still wanted to see if the new X5 was really that much better than the 2018 model.

From the second we got into the X5 it was just a 'wow' experience. The seats were incredibly comfortable, the interior was solid (more than any recent BMW I've been in), we felt something on our arms...freakin' heated armrests...wow, I discovered gesture controls when I accidentally muted the radio and when I learned it was supposed to do that and the Genius showed us more it was just so cool. The engine and transmission were uber refined, swift acceleration with a muted but tastefully sporty exhaust note. Handling was incredible for such a heavy vehicle; its size and weight disappeared around us as we drove it (unlike the Q7 and Velar which felt big). The X5 is just a special car, they really did an outstanding job with it.

since i am current owner of X4M40i i can only say that this is by far best engine I have ever driven. but - and this is important; i did lots of research before buying this engine for X chassis. i also have two kids and in a year or so, space has become a problem. that's why I'm gonna sell it really soon and go for larger space in X5.

I also owned M240i for a while and 340i. that was time when I fell in love with this engine. it's great for second car. but for a family sport SUV, I am going with M50d.
what is true is that X class is just too heavy for this engine. X3 and X4 are just on the weight limit. adding another 300 kilos compared to X5 is a no go for me. besides, one would definitely loose more with additional air resistance.

there's another thread where I said I would be buying 50i but since it's not avail on EU market I believe only diesel engine is appropriate. if you are thinking about consumption (even if just a little) than you gotta stop thinking about this. it's just too heavy.
only petrol engine for X5/6 per my opinion is pure M. just my 5 cents to it...

I drove a demo x3m40i. It had an attractive price with low miles so I wanted to buy it. It reminded me of the m cars I drove at Bmw’s performance driving school in thermal. During the brief test drive I realized that the qualities I like in an m2 or m4 are not what I want in my suv. I want my suv to be more luxurious with a bit of sport. The regular X5 is perfect for that role.

Why do you think the suspension tune will be different? Won't they just include M package in the base price and call it M50. Don't you think they will reserve the real suspension upgrade till M x5.
Judging from M550 - suspension is not any different from M package 540.
Power you are right about - x5 50 does not need more power it is insane. But by your logic if 50 is underrated (which i believe) wont new engine be as well, so it might make more than 523HP - who will need a real M x5

I'm more confused though on what they are doing with that B58 engine and different power levels. Original B58 - 320HP. New one 335 at low and 382HP at high output. And than - there is X3 M40 with 355
And why is everyone saying it is so much faster then 335 HP x5 - really only 20 HP difference?

Just for reference, Dinan dyno tested a stock G01 X3 M40i and at the wheels, the horsepower was 354. Crank at 445hp.

I had an X3 M40i and speaking from experience any M Performance model is tuned differently. They are just a little under a full blown //M car. The suspension in my M40i was way firmer than any M Sport vehicle and bordered on a true sports coupe firmness. If you don't believe me go drive one, they're a blast but the tubing is in fact different. I know the M50i will be the same. For comparison the same is true with a M550i vs the older 550i and a M240i vs the normal 235i etc.

The 50i is quick that much I can say. BMW rated my M40i at 355hp/369lb-ft yet it best their 0-60 time by 0.3s which is a lot (4.3s was my best vs 4.6s) even with AWD helping it still needs more raw power to be that quick at 4300lbs. For comparison the X5 does 60 in 4.3s too but weighs 5200lbs so it's not magic just power + AWD

I'm not sure if say they are a little under an M car. Wait until the new X5M and X3M are out / they will be way ahead in performance. I have an M5 as well (F10) and the car isn't even close to a regular 5 series outside of looks.

That's how BMW positions them, M Sport is a body kit and if your lucky some other small things that are lightly tuned (suspension exhaust), M Performance is a much bigger step up and closer to an actual //M but there's still room between those. BMW wouldn't make the difference so small as to canibalize their //M lineup. I highly recommend driving an M240i/M550i/M40i to see. There is a noticable different not only in performance and handling but ride quality. Another member on here (don't recall his name) the M40i in comfort was stiffer than the X5 40i in sport mode; this statement is very true from experience.

Ok. Imthink i figured out the confusion with b58 engine.

https://www.wardsauto.com/2019-10-be...arged-dohc-i-6

Bmw uses 2. Variants of it now. TU 0. And TU 1. Turns out x5 already has the updated. Version and is not changing in July. Evryone else should get this TU1 update in July

New B58 engine (code number B58B30M1) in x5 also will power the forthcoming X7 three-row SUV, while the earlier version of the B58 (code number B58B30M0) remains the Bavarian workhorse, seeing high volume in the 2-Series, 4-Series, 5-Series, 6-Series and 7-Series cars, as well as the X3 and X4 utility vehicles.

Both engines have 2 levels of tune - low and high

TU 0 low is 320 in all the above models and high at 355 in x3 m40 only

TU1 low is 335 HP in all vehicles and 382 high in M340 and z4 m40

I recently saw this in an Engineering Explained video. I'm going to spell an engine code vertically and define the elements.

B = BMW
5 = 6cyl (go figure)
8 = Gasoline, turbo, valvetronic
B = Gasoline, longitudinal
3
0 = Displacement (30)
O = Performance class
1 = Revision

BMW has 6 performance classes in the following order: K, U, M, O, T, S. So that tells us that the BMW has gone from U up to M, in the middle of the potential variants. I'm not sure if a T or S version of the B58 exists yet, probably in the new M340i?

Is it a diesel? I understand the B series architecture was designed to support diesel versions as well in addition to being modular (hence the I4 versions).

I think TU just means technical update. the code for the engine is the long one - you are correct in decoding it.

TU0 = B58B30M0
TU1 = B58B30M1

I am intrigued by the X3 M40i. I didn't know about its existence before I bought my X5. If I had to be honest, I prefer the overall exterior look of the X3, but the X5's interior is way better. Wish I had at least driven the X3 M40i

I went to the online configurator and saw that a fully optioned X3 M40i was still less than the sticker of my moderately equipped X5
