The start: 0 to 100 km/h

Off the line, the Boxster hits 100 km/h in 5.65 s versus 5.73 s for the 430i. The 0.08 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the Boxster is doing 136 km/h against 132 km/h for the 430i. The gap is 0.05 s. The gap remains stable from the start.

At 400 metres standing start, the Boxster crosses the line in 13.74 s versus 13.97 s. The 0.23 s gap represents roughly 10 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 191 km/h versus 185 km/h. At 1,000 metres, the Boxster finishes in 24.75 s versus 25.35 s, with a 0.59 s lead. Both vehicles have similar top speeds (254 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 is capped at 264 km/h, the 430i 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 (4.87 kg/hp vs 5.99 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.91 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
