Off the line, the 911 Carrera hits 100 km/h in 4.25 s versus 8.14 s for the 420i Convertible. At this point, the 911 Carrera leads by 3.90 s and sits roughly 20 m ahead.
At 200 metres, the 911 Carrera is doing 156 km/h against 115 km/h for the 420i Convertible. The gap is 2.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera crosses the line in 12.20 s versus 15.96 s. The 3.76 s gap represents roughly 141 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera continues to build its lead. At 600 metres, it runs at 217 km/h versus 161 km/h. At 1,000 metres, the 911 Carrera finishes in 21.92 s versus 28.97 s, with a 7.05 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera is capped at 295 km/h, the 420i 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 (3.81 kg/hp vs 9.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 3.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Carrera 991.2 wins (4,25 s vs 8,14 s).
