The start: 0 to 100 km/h

Off the line, the Boxster hits 100 km/h in 5.65 s versus 7.69 s for the 220i Convertible. At this point, the Boxster leads by 2.04 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster is doing 136 km/h against 115 km/h for the 220i Convertible. The gap is 0.95 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster crosses the line in 13.74 s versus 15.61 s. The 1.86 s gap represents roughly 71 m of track - a gap visible to the naked eye.

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 160 km/h. At 1,000 metres, the Boxster finishes in 24.75 s versus 28.82 s, with a 4.07 s lead.

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 220i Convertible at 226 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 8.37 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.89 seconds. The 2.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
