Off the line, the 911 Carrera Cabriolet hits 100 km/h in 4.43 s versus 7.75 s for the 420d Convertible. At this point, the 911 Carrera Cabriolet leads by 3.33 s and sits roughly 14 m ahead.
At 200 metres, the 911 Carrera Cabriolet is doing 153 km/h against 116 km/h for the 420d Convertible. The gap is 1.85 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera Cabriolet crosses the line in 12.42 s versus 15.64 s. The 3.22 s gap represents roughly 122 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera Cabriolet continues to build its lead. At 600 metres, it runs at 214 km/h versus 161 km/h. At 1,000 metres, the 911 Carrera Cabriolet finishes in 22.28 s versus 28.69 s, with a 6.41 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera Cabriolet is capped at 291 km/h, the 420d Convertible at 236 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 (4.00 kg/hp vs 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 3.33 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Carrera Cabriolet 991.2 wins (4,42 s vs 7,75 s).
