Off the line, the Bmw 840i hits 100 km/h in 4.95 s versus 5.73 s for the Bmw 430i. At this point, the Bmw 840i leads by 0.78 s and sits roughly 6 m ahead.
At 200 metres, the Bmw 840i is doing 142 km/h against 132 km/h for the Bmw 430i. The gap is 0.49 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i crosses the line in 13.15 s versus 13.97 s. The 0.82 s gap represents roughly 37 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 840i continues to build its lead. At 600 metres, it runs at 198 km/h versus 185 km/h. At 1,000 metres, the Bmw 840i finishes in 23.75 s versus 25.35 s, with a 1.59 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 Bmw 840i and the Bmw 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 (5.03 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 0.78 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 5,73 s).
840i G15 goes from 0 to 100 km/h in 4,95 seconds (calibrated simulation).
