The start: 0 to 100 km/h

Off the line, the Boxster S Black Edition hits 100 km/h in 4.98 s versus 6.24 s for the 430i Convertible. At this point, the Boxster S Black Edition leads by 1.26 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S Black Edition is doing 145 km/h against 127 km/h for the 430i Convertible. The gap is 0.79 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster S Black Edition crosses the line in 13.03 s versus 14.45 s. The 1.42 s gap represents roughly 61 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Boxster S Black Edition continues to build its lead. At 600 metres, it runs at 202 km/h versus 177 km/h. At 1,000 metres, the Boxster S Black Edition finishes in 23.47 s versus 26.31 s, with a 2.84 s lead. Both vehicles have similar top speeds (263 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Boxster S Black Edition is capped at 275 km/h, the 430i Convertible at 250 (i.e. 155 mph - industry threshold) 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 (4.18 kg/hp vs 6.65 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.87 seconds. The 1.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
