The start: 0 to 100 km/h

Off the line, the Boxster S hits 100 km/h in 5.08 s versus 7.60 s for the 220i Convertible. At this point, the Boxster S leads by 2.52 s and sits roughly 12 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S is doing 143 km/h against 118 km/h for the 220i Convertible. The gap is 1.34 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster S crosses the line in 13.23 s versus 15.54 s. The 2.31 s gap represents roughly 90 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 198 km/h versus 163 km/h. At 1,000 metres, the Boxster S finishes in 23.87 s versus 28.42 s, with a 4.56 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 274 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 (4.32 kg/hp vs 8.59 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.27 seconds. The 2.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
