Hi!

Just wondering if anyone knows what M40i stands for

the motor in my X4 is 3.0-liter, M Performance TwinPower Turbo inline 6-cylinder.

Nothing there is a 4 or a 40i

thanks!

40i or M40i means the car has a B58 engine. It’s just a marketing name, without any roots in reality.

the 40i = the B58 engine across all BMW cars

The M in this case means "M Performance" - the watered-down but still souped-up sub-brand.

"M" cars are the real range-toppers. M Performance are below that.
