Off the line, the 840i xDrive hits 100 km/h in 4.82 s versus 4.94 s for the SQ2. The 0.12 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 840i xDrive is doing 141 km/h against 133 km/h for the SQ2. The gap is 0.20 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 840i xDrive crosses the line in 13.06 s versus 13.47 s. The 0.41 s gap represents roughly 19 m of track - two to three car lengths.
Past 400 metres, the 840i xDrive continues to build its lead. At 600 metres, it runs at 197 km/h versus 190 km/h. At 1,000 metres, the 840i xDrive finishes in 23.73 s versus 24.55 s, with a 0.82 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 257 km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the 840i 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 (5.39 kg/hp vs 5.12 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.36 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840i xDrive G15 wins (4,82 s vs 4,94 s).
840i xDrive G15 goes from 0 to 100 km/h in 4,82 seconds (calibrated simulation).
