The start: 0 to 100 km/h

Off the line, the 911 Turbo S hits 100 km/h in 2.95 s versus 3.15 s for the 812 GTS. At this point, the 911 Turbo S leads by 0.20 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo S is doing 176 km/h against 178 km/h for the 812 GTS. The gap is 0.10 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.57 s versus 10.66 s. The 0.09 s gap represents roughly 5 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The 911 Turbo S maxes out at 317 km/h while the 812 GTS keeps accelerating towards 327 km/h. At 600 metres, the gap has dropped to 0.05 s.

At 1,000 metres, the 911 Turbo S finishes in 19.22 s versus 19.24 s, with just 0.02 s to spare. The 812 GTS fails to fully close the launch gap.

What the numbers don’t tell you

Electronically capped at 317 km/h, the 911 Turbo S never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (2.04 kg/hp vs 2.83 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.30 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
