Off the line, the Bmw M4 Competition hits 100 km/h in 3.83 s versus 4.95 s for the Bmw 840i. At this point, the Bmw M4 Competition leads by 1.12 s and sits roughly 9 m ahead.
At 200 metres, the Bmw M4 Competition is doing 163 km/h against 142 km/h for the Bmw 840i. The gap is 0.94 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 Competition crosses the line in 11.61 s versus 13.15 s. The 1.54 s gap represents roughly 73 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Competition continues to build its lead. At 600 metres, it runs at 227 km/h versus 198 km/h. At 1,000 metres, the Bmw M4 Competition finishes in 20.89 s versus 23.75 s, with a 2.86 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 M4 Competition and the Bmw 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 (3.38 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 1.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
