Off the line, the 840i xDrive hits 100 km/h in 4.81 s versus 5.73 s for the 430i. At this point, the 840i xDrive leads by 0.92 s and sits roughly 8 m ahead.
At 200 metres, the 840i xDrive is doing 142 km/h against 132 km/h for the 430i. The gap is 0.59 s. The challenger starts to claw back ground.
At 400 metres standing start, the 840i xDrive crosses the line in 13.05 s versus 13.97 s. The 0.92 s gap represents roughly 41 m of track - a gap visible to the naked eye.
Past 400 metres, the 840i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 185 km/h. At 1,000 metres, the 840i xDrive finishes in 23.65 s versus 25.35 s, with a 1.70 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the 840i xDrive and the 430i are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.39 kg/hp vs 5.99 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.91 seconds. The 0.92 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 (4,81 s vs 5,73 s).
840i xDrive G15 goes from 0 to 100 km/h in 4,81 seconds (calibrated simulation).
