The start: 0 to 100 km/h

Off the line, the Boxster S hits 100 km/h in 5.17 s versus 9.45 s for the 218i Convertible. At this point, the Boxster S leads by 4.28 s and sits roughly 18 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S is doing 141 km/h against 107 km/h for the 218i Convertible. The gap is 1.98 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster S crosses the line in 13.32 s versus 16.81 s. The 3.49 s gap represents roughly 121 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 197 km/h versus 148 km/h. At 1,000 metres, the Boxster S finishes in 23.98 s versus 31.02 s, with a 7.03 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 218i Convertible at 207 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 (4.37 kg/hp vs 11.03 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.40 seconds. The 4.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
