Off the line, the Boxster S Manual hits 100 km/h in 4.85 s versus 8.14 s for the 420i Convertible. At this point, the Boxster S Manual leads by 3.30 s and sits roughly 21 m ahead.
At 200 metres, the Boxster S Manual is doing 145 km/h against 115 km/h for the 420i Convertible. The gap is 1.90 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S Manual crosses the line in 12.93 s versus 15.96 s. The 3.03 s gap represents roughly 115 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster S Manual continues to build its lead. At 600 metres, it runs at 202 km/h versus 161 km/h. At 1,000 metres, the Boxster S Manual finishes in 23.37 s versus 28.97 s, with a 5.59 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster S Manual is capped at 274 km/h, the 420i 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 (4.32 kg/hp vs 9.18 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 3.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster S Manual wins (4,84 s vs 8,14 s).
Boxster S Manual goes from 0 to 100 km/h in 4,84 seconds (calibrated simulation).
