Off the line, the Bmw M4 Competition hits 100 km/h in 3.83 s versus 7.44 s for the Bmw 420i. At this point, the Bmw M4 Competition leads by 3.61 s and sits roughly 15 m ahead.
At 200 metres, the Bmw M4 Competition is doing 163 km/h against 117 km/h for the Bmw 420i. The gap is 2.23 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 15.38 s. The 3.77 s gap represents roughly 143 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 163 km/h. At 1,000 metres, the Bmw M4 Competition finishes in 20.89 s versus 28.23 s, with a 7.34 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw M4 Competition is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 420i at 240 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.38 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 3.61 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.
