Off the line, the Boxster hits 100 km/h in 5.72 s versus 7.75 s for the Bmw 420d Convertible. At this point, the Boxster leads by 2.04 s and sits roughly 11 m ahead.
At 200 metres, the Boxster is doing 132 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 0.91 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster crosses the line in 13.99 s versus 15.64 s. The 1.65 s gap represents roughly 64 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 187 km/h versus 161 km/h. At 1,000 metres, the Boxster finishes in 25.24 s versus 28.69 s, with a 3.44 s lead. Both vehicles have similar top speeds (244 vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Boxster is capped at 262 km/h, the Bmw 420d 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 9.34 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 2.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
