Off the line, the Bmw M4 Convertible hits 100 km/h in 4.69 s versus 4.94 s for the Boxster S. The 0.25 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw M4 Convertible is doing 151 km/h against 145 km/h for the Boxster S. The gap is 0.18 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Convertible crosses the line in 12.64 s versus 13.01 s. The 0.37 s gap represents roughly 18 m of track — two to three car lengths.
Past 400 metres, the Bmw M4 Convertible continues to build its lead. At 600 metres, it runs at 213 km/h versus 202 km/h. At 1,000 metres, the Bmw M4 Convertible finishes in 22.51 s versus 23.47 s, with a 0.95 s lead. Despite a higher top speed (273 km/h), the Boxster S never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the Bmw M4 Convertible is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Boxster S at 279 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 (4.15 kg/hp vs 4.14 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.23 seconds. The 0.25 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.
