The start: 0 to 100 km/h

Off the line, the S8 hits 100 km/h in 3.83 s versus 4.77 s for the 911 Carrera (Manual). At this point, the S8 leads by 0.94 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S8 is doing 157 km/h against 148 km/h for the 911 Carrera (Manual). The gap is 0.75 s. The challenger starts to claw back ground.

At 400 metres standing start, the S8 crosses the line in 11.81 s versus 12.81 s. The 1.00 s gap represents roughly 50 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S8 continues to build its lead. At 600 metres, it runs at 222 km/h versus 209 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 22.88 s, with a 1.62 s lead. Despite a higher top speed (289 km/h), the 911 Carrera (Manual) never recovers its launch deficit.

What the numbers don’t tell you

The S8 features all-wheel drive (AWD) against the 911 Carrera (Manual)’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the S8 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 911 Carrera (Manual) at 289 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 4.13 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.09 seconds. The 0.94 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
