The start: 0 to 100 km/h

Off the line, the 718 Boxster hits 100 km/h in 4.65 s versus 5.86 s for the 230i Convertible. At this point, the 718 Boxster leads by 1.22 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Boxster is doing 147 km/h against 129 km/h for the 230i Convertible. The gap is 0.81 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Boxster crosses the line in 12.76 s versus 14.21 s. The 1.45 s gap represents roughly 63 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Boxster continues to build its lead. At 600 metres, it runs at 204 km/h versus 178 km/h. At 1,000 metres, the 718 Boxster finishes in 23.08 s versus 26.01 s, with a 2.93 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Boxster is capped at 274 km/h, the 230i 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 (4.45 kg/hp vs 6.25 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.32 seconds. The 1.22 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
