Here is a list of what the x3m does better imo: 1. steering feel is much improved 2. engine top end is amazing 3. handling is less numb and has more play, far less understeer at 7/10's- you can feel the torque vectoring working as well as the rear biased awd. much much more fun. 4. it is much lighter and tossable Before you feel disappointed, I think there's plenty of stuff to like and enjoy. You may need to row the gears more to keep the engine out of the laggy part of the rpm.

GLC63S 0-60 3.4 5-60 4.6 delta 1.2 seconds STELVIO QUAD 0-60 3.3 5-60 4.3 delta 1 second They are better (GLC is actually close), so it is the tuning of the car bmw chose to go with.

I came from a tuned B58 M240i and it had tons of low and mid range torque, was really quick. I don't find myself missing that low end though, maybe I'm in the minority but love how the power band of the S58 is, top end is brutal. Everyone these days is so used to instant down low torque with tiny turbos every car has now. Hate how most cars with the massive low end shove die off up top. I'd rather have to work for it...creates a more involving driving and motorsport experience.
People just need to re-adjust their driving perspective and style when driving the S58. Once you stop complaining about the lack of low end, and just understand how the power band works...I find zero complaints about it, and the car is simply brutally fast.

0-60 4.1 5-60 4.4 delta 0.3 seconds the new Velar SV Auto is also pretty damn good for a 4770 lb truck, strange its the same engine but weighs more than SVR and its quicker... both C&D results 0-60 3.8 5-60 4.2 actually only cost about $10,000 more and is much nicer quality with a V8 sure the 0-60 doesnt look amazing and 1/4 mile is 12.20 vs 11.60 BUT at a stop light it looks like it will take out the X3M... oh yeah X3M destroys the F Pace and Velar in the skid, 0.97 vs 0.85 and breaking 146 ft vs 165 and 174. Hell the X3M broke quicker than the new CORVETTE Z51, now thats SAD, 3638lb corvette took 154 ft, 4550 lb X3M took 146 |

I looked up the M40i and X3MC torque curves a while back. The X3MC almost matches the M40i at 2,000 rpm. Either the X3MC has higher gearing than M40i or the X3MC feels slow at low revs because at high revs it’s so much quicker. Which is it?

I still find plenty to enjoy in the X3M, it is not perfect, but I am pretty happy about the top end of the engine. It definitely reminds me more of a muscle car than a precise sports car. Fun is definitely on the menu with this little suv.

Gear for gear beyond 2600rpm the X3MC walks the M40i, held in 6th at low speed you pull a few yards before the inevitable, if we did a side by side roll at 40mph in 2nd where would your money be? or in 3rd at 60? or 4th @ 80 etc.......The X3M produces more power from 2600rpm it's not just at low revs.. My 740d could keep up with an M40i the X3M is in another league.

It gets better but truly need some tuning to open it up. Alpina seems to have addressed this with their B3 using the same S58 motor. I think a lot is based on how BMW tunes the engine it seems better fitted for M3/M4 and not X3M/X4M. My 2 cents

I wish a mild hybrid had been an option, to cover the torque down low, and then let the s58 do it's thing up high. Seems like Benz is doing some fun stuff in that direction.

If you are cruising on the highway lets say in 7th or 8th gear @ 2000 RPMS and you just want to apply throttle to pass or accelerate without downshifting, there is nothing there since the power does not come on until over 3000 rpms which causes you to have to downshift. If you compare other Turbo BMWs TQ and the power band comes on much sooner. For instance an F8X. In 7th gear, you can accelerate easily in 7th @ 2000 rpms while cruising on the highway without downshifting. On the S58, due to its design, there is nothing below 3000 rpms and a tune will not change that. |

Yeah but it still feels slow in that scenario. That's just the plain bottom line.

F8X comp is a 3,6xx lb sedan, with 444 hp. F97 comp is a 4,5xx lb suv, with 503 hp. About 900 lbs of additional weight is being pulled by less than 60 hp. You're not going to get what you want in any performance SUV, to be honest. RWD > AWD at any highway speeds, and sedan > suv at highway speeds. If you compare the 0-100 mph values of sports sedans vs a comparable performance suv, you're going to see that AWD and aerodynamics start to make a difference. This is at WOT, much less at lower RPM's- it is just not feasible or possible to expect throttle response to be close. It is a testimony to BMW engineering that the F97 is 8 seconds to 100, compared to many of its competitors, that is excellent. Besides, why would you not get every chance to let the engine sing up high? That is the most enjoyable part of the experience imo. Perhaps a Tesla, with just one gear is best for your needs, instant torque, but nothing above the initial punch.
