Off the line, the M850i xDrive hits 100 km/h in 3.83 s versus 8.62 s for the 118d xDrive. At this point, the M850i xDrive leads by 4.79 s and sits roughly 22 m ahead.
At 200 metres, the M850i xDrive is doing 160 km/h against 112 km/h for the 118d xDrive. The gap is 2.84 s. The challenger starts to claw back ground.
At 400 metres standing start, the M850i xDrive crosses the line in 11.71 s versus 16.28 s. The 4.58 s gap represents roughly 164 m of track - a gap visible to the naked eye.
Past 400 metres, the M850i xDrive continues to build its lead. At 600 metres, it runs at 224 km/h versus 155 km/h. At 1,000 metres, the M850i xDrive finishes in 21.07 s versus 29.87 s, with a 8.79 s lead.
Both rivals are electronically governed, but not at the same level: the M850i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 118d xDrive at 210 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.64 kg/hp vs 9.80 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.20 seconds. The 4.79 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M850i xDrive G15 wins (3,83 s vs 8,62 s).
M850i xDrive G15 goes from 0 to 100 km/h in 3,83 seconds (calibrated simulation).
