The start: 0 to 100 km/h

Off the line, the 911 Turbo hits 100 km/h in 3.35 s versus 3.83 s for the 911 Carrera 4S. At this point, the 911 Turbo leads by 0.48 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo is doing 168 km/h against 161 km/h for the 911 Carrera 4S. The gap is 0.43 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Turbo crosses the line in 11.13 s versus 11.74 s. The 0.60 s gap represents roughly 33 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 232 km/h versus 223 km/h. At 1,000 metres, the 911 Turbo finishes in 20.22 s versus 21.16 s, with a 0.94 s lead. Both vehicles have similar top speeds (309 vs 304 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Turbo is capped at 312 km/h, the 911 Carrera 4S at 304 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 (3.10 kg/hp vs 3.50 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.55 seconds. The 0.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
