Off the line, the Bmw M4 Convertible hits 100 km/h in 4.69 s versus 4.99 s for the Boxster Spyder. At this point, the Bmw M4 Convertible leads by 0.30 s and sits roughly 5 m ahead.
At 200 metres, the Bmw M4 Convertible is doing 151 km/h against 146 km/h for the Boxster Spyder. The gap is 0.29 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 13.04 s. The 0.39 s gap represents roughly 20 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 207 km/h. At 1,000 metres, the Bmw M4 Convertible finishes in 22.51 s versus 23.27 s, with a 0.75 s lead. Despite a higher top speed (266 km/h), the Boxster Spyder never recovers its launch deficit.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw M4 Convertible never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.15 kg/hp vs 3.94 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.16 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
