Off the line, the Boxster S hits 100 km/h in 5.17 s versus 7.75 s for the 420d Convertible. At this point, the Boxster S leads by 2.59 s and sits roughly 13 m ahead.
At 200 metres, the Boxster S is doing 141 km/h against 116 km/h for the 420d Convertible. The gap is 1.30 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.32 s versus 15.64 s. The 2.32 s gap represents roughly 89 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 197 km/h versus 161 km/h. At 1,000 metres, the Boxster S finishes in 23.98 s versus 28.69 s, with a 4.71 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 km/h, the 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 (4.37 kg/hp vs 9.34 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 2.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster S wins (5,17 s vs 7,75 s).
Boxster S goes from 0 to 100 km/h in 5,17 seconds (calibrated simulation).
