good greeting ,
I found a video on YT that shows the difference in drag racing between the xDrive 50 and the M60.
The race wasn’t perfect (rainy), and both cars didn’t do their best. The same channel previously tested the M60, and it did 0-62 mph (0-100 km/h) in 3.59 versus the X6M.
Regardless, it shows the difference in strength. The M60 has a larger, oil-cooled rear engine, which is the contributing factor.
Both are too fast for a heavy SUV.
