First Video of a 2018 BMW M550ix in the 1/4 - 12.3@115 MPH

BIMMERPOST
     Featured on BIMMERPOST.com
Hi everyone, I believe this is the first 2018 M550ix 1/4 mile test...fully stock, no changes to tire pressure, fuel, weight or wheels. Average/poor DA for the summer (over +2000).

I wanted to see how the new M550ix would do. I guessed fairly correctly thinking mid 12's or better. The car was super consistent running within a hundredth of a second in three passes (and tenths of a MPH).

The day was hot and humid, and there was 3/4's of a tank of fuel.

One thing to mention - either there is an issue with the trans, or the car is tuned this way with purpose; 1-2 and 2-3 shift pull hard and then right before redline drop power (pulling you forward almost) and then shifts. 3-4 shift and beyond does not do this. Personally, I believe this to be intentional, and if tuned out the car, it will be much quicker and faster - forget about adding boost. I would say 12.0's to 11.9's just but making it shift crisply and with full power to redline.

I am quite impressed with the performance - for a non M5 luxury car.

Impressive results for a 4 door sedan
DSC ON and OFF and Traction Control Settings could have made a difference in timing sheet as well. Not too much but just

I actually tested both. 12.3 to 12.7 just by using launch control. I had DSC off, traction control off, S+, sport shift, launch control, and auto shifted.

I would say with solid DA (it was over +2000) - less fuel and less tire pressure I could get it down to a low 1.7x from the high 1.8's and run a 12.0, maybe a 11.999.

Certainly a quick car, but Is it all that impressive?

As a point of comparison I've done 12.8@108mph in a 335d remapped to 360bhp. I'd have thought this would have been quite a bit quicker than that.

Makes me feel less annoyed that they aren't going to sell them in the UK though.

It's very impressive! just so you know, a half second difference in the 1/4mile is HUGE.

1/2 second in a much bigger/heavier/more luxurious car running bone stock is pretty impressive.

It has 480bhp and weighs about 2 tonnes (UK measurement) so about 240 bhp per tonne

My car has 360bhp and weights about 1.75 tonnes, so about 205bhp per tonne, though I suppose my car has more torque per tonne...

Both have xdrive, so traction will be much the same.

Maybe you guys are right, I just expected that with that many extra horses it would translate in to a much much quicker car. There are other guys in the UK with similar cars to me going even quicker!

E92 M3's were slower than my car to the 1/4 mile marker, but mainly due to traction issues, their terminal velocities were around the 120mph mark, so I suppose I thought that this car would have my traction but their power and even more torque, so comfortably go below 12s.

Though I accept an E92 M3 is much lighter than a 5 series!

Pretty impressive for a luxury sedan. I don't think I will ever take my M550i to track, but it's good to know its potential

This car is fast from 0-60 due to x-drive but not so much at the quarter mile. F10 M5 will smoke it beyond the 0-60 where they are neck and neck. The new M5 will be a real beast with 600 HP and X-Drive.

Of course...100 more HP....

This logic doesn't make sense lol. The difference between this time/trap speed and your time/trap is massive!

And this car is a few hundred pounds chubbier lol

I double checked, my time was 12.76 so it's 0.4 seconds. Still expected a V8 petrol with 480bhp to be quicker than that.

F10 m5 did 11.9 @ 120, which makes it 0.4 quicker than m550 having 100 more bhp. I don?t get what?s so unbelievable about your car being 0.4 and 7mph slower while having 100 bhp less and less weight. My own tuned 335i did 12.67 @ 111. I?ve driven the G30 which definitely felt quicker. Plus it?s the first time 1/4 mile has been done, I?m sure over time, with better conditions we?ll get better times.

It has already been said - but half second is a large difference. Especially as you have a tuned car. This car with even a basic tune will run high 11's at 120+ MPH.

Yeah But This....

12.3 is bad actually guys. Maybe when the engine is even more broken in. 12 is more accurate and I'm sure the OP was having a bad day (Technically).

This Audi below hit 12.2 and its not the RS6 which is the M5 competitor

It's all math my friend. The car for its heft and stock tune - which is hampering its performance - is the result. As I said - with a better DA and less fuel in my tank, and with less that 42 psi in my PS4's - I could probably get this car down to a 12.0 or 11.999.

I knew the car was quicker than the outgoing M5 to 60 MPH - but I was pleasantly surprised it was as solid as it was in the 1/4.

And although I have no plans to tune or mod this car (I am fortunate to have alternatives there) - someone will and they will easily run mid to low 11's - maybe even high 10's at 125+ with a tune and downpipes.

I will agree an F10 M5 will beat an M550ix in the 1/4 - but it won't smoke it.

In fact, I would say the M550ix would win because of its AWD advantage 8/10 times against most drivers (especially at a track where stock tires go to spin).

The mere fact we are discussing both in the same sentence is crazy as the M550ix is a luxury car.

First - you cannot even see the time - but I checked fastestlaps and they do run 12.1 at 115 MPH.

Now if you have experience racing - you would know that MPH is the cars potential. Exactly what I ran with the M550ix. And a 12.3. The S6 IS the competitor to the M550ix. This isn't the new M5. My car was driven with a .025 reaction time in auto using launch control. So there isn't much technically remaining - besides the fact the DA was high because it was super hot and humid, I had 3/4 tank of fuel and 42 psi in my tires.

Beyond that - you're right on the money.
