Off the line, the Boxster S hits 100 km/h in 5.07 s versus 7.83 s for the 420i Gran Coupé. At this point, the Boxster S leads by 2.76 s and sits roughly 13 m ahead.
At 200 metres, the Boxster S is doing 143 km/h against 115 km/h for the 420i Gran Coupé. The gap is 1.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.18 s versus 15.69 s. The 2.51 s gap represents roughly 95 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 199 km/h versus 160 km/h. At 1,000 metres, the Boxster S finishes in 23.72 s versus 28.81 s, with a 5.09 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 272 km/h, the 420i Gran Coupé at 235 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 (4.39 kg/hp vs 8.80 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.94 seconds. The 2.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster S 987 wins (5,07 s vs 7,83 s).
Boxster S 987 goes from 0 to 100 km/h in 5,07 seconds (calibrated simulation).
