1/4 mile time M240 xdrive

I went to drag strip for the first time.

From the search, I knew that the 1/4 mile time should be around 12.5 sec.

Car was in sports+ mode with transmission in sport auto. Used launch control every time.

My best run was 12.39 sec at 109.4 mph which is very respectable and consistent.

I did total of 9 run (7 runs almost back to back then 2 more runs after an hour) and time was so consistent.
Best run was the 7th run. (worst was 4th run, 12.67 sec at 108.4 mph with manual shifting)

Weather was around 80F at the beginning and went down to 70F at the end.

Intake air temperature was between 120~135 F before the start, quickly dropped to 110F as the car moving.

I was impressed how consistent this car ran.

Trap speed was within 1 mph and time was within 0.15 sec (excluding the one I shifted manually)
No heat soak issue.

This consistency kinda made the drag race boring.
Not much to do to improve the time. lol
