Off the line, the Boxster S hits 100 km/h in 5.07 s versus 5.30 s for the 840i xDrive Convertible. The 0.23 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Boxster S is doing 143 km/h against 136 km/h for the 840i xDrive Convertible. The gap is 0.16 s. The gap remains stable from the start.
At 400 metres standing start, the Boxster S crosses the line in 13.18 s versus 13.56 s. The 0.38 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 199 km/h versus 190 km/h. At 1,000 metres, the Boxster S finishes in 23.72 s versus 24.59 s, with a 0.87 s lead.
Both rivals are electronically governed, but not at the same level: the 840i xDrive Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Boxster S at 272 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 (5.75 kg/hp vs 4.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.18 seconds. The 0.23 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.
