The start: 0 to 100 km/h

Off the line, the 911 Carrera S hits 100 km/h in 4.44 s versus 9.45 s for the 218i Convertible. At this point, the 911 Carrera S leads by 5.01 s and sits roughly 19 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera S is doing 154 km/h against 107 km/h for the 218i Convertible. The gap is 2.58 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera S crosses the line in 12.30 s versus 16.81 s. The 4.51 s gap represents roughly 154 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera S continues to build its lead. At 600 metres, it runs at 216 km/h versus 148 km/h. At 1,000 metres, the 911 Carrera S finishes in 21.94 s versus 31.02 s, with a 9.08 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera S is capped at 303 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 (3.44 kg/hp vs 11.03 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.40 seconds. The 5.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
