The start: 0 to 100 km/h

Off the line, the Boxster S hits 100 km/h in 5.07 s versus 9.12 s for the 218d Convertible. At this point, the Boxster S leads by 4.05 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S is doing 143 km/h against 109 km/h for the 218d Convertible. The gap is 2.08 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster S crosses the line in 13.18 s versus 16.65 s. The 3.46 s gap represents roughly 124 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 199 km/h versus 152 km/h. At 1,000 metres, the Boxster S finishes in 23.72 s versus 30.48 s, with a 6.76 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 272 km/h, the 218d Convertible at 208 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 (4.39 kg/hp vs 10.43 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.20 seconds. The 4.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
