Off the line, the Bmw M4 Competition Convertible hits 100 km/h in 4.43 s versus 7.75 s for the Bmw 420d Convertible. At this point, the Bmw M4 Competition Convertible leads by 3.32 s and sits roughly 18 m ahead.
At 200 metres, the Bmw M4 Competition Convertible is doing 148 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 1.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M4 Competition Convertible crosses the line in 12.51 s versus 15.64 s. The 3.13 s gap represents roughly 118 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Competition Convertible continues to build its lead. At 600 metres, it runs at 209 km/h versus 161 km/h. At 1,000 metres, the Bmw M4 Competition Convertible finishes in 22.55 s versus 28.69 s, with a 6.14 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw M4 Competition Convertible is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw 420d Convertible at 236 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 (3.98 kg/hp vs 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 3.32 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.
