The start: 0 to 100 km/h

Off the line, the 911 Carrera hits 100 km/h in 4.66 s versus 7.04 s for the 420d. At this point, the 911 Carrera leads by 2.39 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera is doing 151 km/h against 119 km/h for the 420d. The gap is 1.36 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera crosses the line in 12.55 s versus 15.10 s. The 2.55 s gap represents roughly 100 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 215 km/h versus 166 km/h. At 1,000 metres, the 911 Carrera finishes in 22.38 s versus 27.77 s, with a 5.40 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 288 km/h, the 420d at 240 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 (3.89 kg/hp vs 8.45 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.60 seconds. The 2.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
