Off the line, the Boxster S hits 100 km/h in 5.08 s versus 7.62 s for the 420i Steptronic Gran Coupe. At this point, the Boxster S leads by 2.55 s and sits roughly 13 m ahead.
At 200 metres, the Boxster S is doing 143 km/h against 118 km/h for the 420i Steptronic Gran Coupe. The gap is 1.35 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.23 s versus 15.55 s. The 2.32 s gap represents roughly 91 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 198 km/h versus 164 km/h. At 1,000 metres, the Boxster S finishes in 23.87 s versus 28.34 s, with a 4.47 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 km/h, the 420i Steptronic Gran Coupe 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 8.53 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.25 seconds. The 2.55 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster S 981 wins (5,08 s vs 7,62 s).
