The start: 0 to 100 km/h

Off the line, the 911 Carrera hits 100 km/h in 4.25 s versus 9.12 s for the 218d Convertible. At this point, the 911 Carrera leads by 4.87 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera is doing 156 km/h against 109 km/h for the 218d Convertible. The gap is 2.70 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera crosses the line in 12.20 s versus 16.65 s. The 4.44 s gap represents roughly 156 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera continues to build its lead. At 600 metres, it runs at 217 km/h versus 152 km/h. At 1,000 metres, the 911 Carrera finishes in 21.92 s versus 30.48 s, with a 8.56 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera is capped at 295 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 (3.81 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 4.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
