Vehicle weight: 4400
Dyno horsepower: 456
¼-mile ET: 12.39 seconds
¼-mile MPH: 110 MPH

ET = ((Weight ÷ HP).333) × 5.825
MPH = ((HP ÷ Weight).333) × 234
In all seriousness - math is never wrong - and the issue is the power outputs are inaccurate. I believe there was a dyno video with the M550ix where the WHP conversion was higher than advertised by BMW.
