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

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.
