Off the line, the Boxster Manual hits 100 km/h in 5.47 s versus 8.14 s for the 420i Convertible. At this point, the Boxster Manual leads by 2.67 s and sits roughly 19 m ahead.
At 200 metres, the Boxster Manual is doing 135 km/h against 115 km/h for the 420i Convertible. The gap is 1.44 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Manual crosses the line in 13.65 s versus 15.96 s. The 2.31 s gap represents roughly 89 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster Manual continues to build its lead. At 600 metres, it runs at 192 km/h versus 161 km/h. At 1,000 metres, the Boxster Manual finishes in 24.66 s versus 28.97 s, with a 4.30 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster Manual is capped at 262 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 (5.15 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 2.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster Manual 987 wins (5,47 s vs 8,14 s).
Boxster Manual 987 goes from 0 to 100 km/h in 5,47 seconds (calibrated simulation).
