Recently I passed 3,000 miles so I decided to try out launch control. My completely stock 2019 X3 M40i with winter tires did 0-60 in 4.5 seconds according to the BMW M lap timer app. Curious to know what other members have been able to achieve without mods.

Pretty much the same as you but with a GPS based time (VBOX or Draggy)

I'm not sure what laptimer is but maybe it uses GPS? If it uses OBD2 you are likely going to get a faster time as these cars have a faster speedo then how fast you are actually going

EDIT: I see the laptimer uses GPS, problem is it doesn't show the grade of the road (i.e. slope + or - which can give or take a couple of tenths)

I think it uses the car's internal sensors, including the GPS.
