Off the line, the 840i hits 100 km/h in 4.95 s versus 5.14 s for the 840i. At this point, the 840i leads by 0.19 s and sits roughly 2 m ahead.
At 200 metres, the 840i is doing 142 km/h against 140 km/h for the 840i. The gap is 0.13 s. The gap remains stable from the start.
At 400 metres standing start, the 840i crosses the line in 13.15 s versus 13.35 s. The 0.20 s gap represents roughly 10 m of track - barely a car length.
Past 400 metres, the 840i continues to build its lead. At 600 metres, it runs at 198 km/h versus 195 km/h. At 1,000 metres, the 840i finishes in 23.75 s versus 24.12 s, with a 0.37 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 and the 840i 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 (5.03 kg/hp vs 5.20 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.77 seconds. The 0.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840i G15 wins (4,95 s vs 5,14 s).
840i G15 goes from 0 to 100 km/h in 4,95 seconds (calibrated simulation).
