Off the line, the Boxster hits 100 km/h in 5.65 s versus 7.62 s for the Bmw 420i Steptronic Gran Coupe. At this point, the Boxster leads by 1.97 s and sits roughly 12 m ahead.
At 200 metres, the Boxster is doing 136 km/h against 118 km/h for the Bmw 420i Steptronic Gran Coupe. The gap is 1.03 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster crosses the line in 13.74 s versus 15.55 s. The 1.80 s gap represents roughly 71 m of track - a gap visible to the naked eye.
Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 191 km/h versus 164 km/h. At 1,000 metres, the Boxster finishes in 24.75 s versus 28.34 s, with a 3.59 s lead.
Both rivals are electronically governed, but not at the same level: the Boxster is capped at 264 km/h, the Bmw 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 (4.87 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 1.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Boxster 981 wins (5,65 s vs 7,62 s).
