The start: 0 to 100 km/h

Off the line, the Cayman hits 100 km/h in 5.52 s versus 9.34 s for the 218i Convertible. At this point, the Cayman leads by 3.82 s and sits roughly 25 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayman is doing 136 km/h against 110 km/h for the 218i Convertible. The gap is 2.02 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayman crosses the line in 13.64 s versus 16.78 s. The 3.15 s gap represents roughly 114 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayman continues to build its lead. At 600 metres, it runs at 190 km/h versus 154 km/h. At 1,000 metres, the Cayman finishes in 24.68 s versus 30.47 s, with a 5.78 s lead.

What the numbers don’t tell you

Electronically capped at 207 km/h, the 218i Convertible never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.70 kg/hp vs 11.47 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.16 seconds. The 3.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
