Off the line, the 812 GTS hits 100 km/h in 3.15 s versus 4.95 s for the Bmw 840i. At this point, the 812 GTS leads by 1.80 s and sits roughly 14 m ahead.
At 200 metres, the 812 GTS is doing 178 km/h against 142 km/h for the Bmw 840i. The gap is 1.60 s. The challenger starts to claw back ground.
At 400 metres standing start, the 812 GTS crosses the line in 10.66 s versus 13.15 s. The 2.49 s gap represents roughly 116 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 198 km/h. At 1,000 metres, the 812 GTS finishes in 19.24 s versus 23.75 s, with a 4.51 s lead.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 840i 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 5.03 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.46 seconds. The 1.80 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 4,95 s).
812 GTS goes from 0 to 100 km/h in 3,15 seconds (calibrated simulation).
