Off the line, the 812 GTS hits 100 km/h in 3.15 s versus 3.76 s for the M850i xDrive. At this point, the 812 GTS leads by 0.61 s and sits roughly 7 m ahead.
At 200 metres, the 812 GTS is doing 178 km/h against 162 km/h for the M850i xDrive. The gap is 0.66 s. The gap remains stable from the start.
At 400 metres standing start, the 812 GTS crosses the line in 10.66 s versus 11.65 s. The 0.99 s gap represents roughly 54 m of track - a gap visible to the naked eye.
Past 400 metres, the 812 GTS continues to build its lead. At 600 metres, it runs at 245 km/h versus 226 km/h. At 1,000 metres, the 812 GTS finishes in 19.24 s versus 20.97 s, with a 1.73 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the M850i xDrive never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (2.04 kg/hp vs 3.57 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.41 seconds. The 0.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 812 GTS wins (3,15 s vs 3,76 s).
812 GTS goes from 0 to 100 km/h in 3,15 seconds (calibrated simulation).
