Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the 911 Carrera 4 hits 100 km/h in 4.16 s versus 7.66 s for the 220d Convertible. At this point, the 911 Carrera 4 leads by 3.50 s and sits roughly 25 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera 4 is doing 155 km/h against 120 km/h for the 220d Convertible. The gap is 2.35 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera 4 crosses the line in 12.19 s versus 15.71 s. The 3.52 s gap represents roughly 137 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera 4 continues to build its lead. At 600 metres, it runs at 215 km/h versus 167 km/h. At 1,000 metres, the 911 Carrera 4 finishes in 22.00 s versus 28.34 s, with a 6.34 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera 4 is capped at 291 km/h, the 220d Convertible at 225 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 (3.95 kg/hp vs 8.34 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.00 seconds. The 3.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
