The start: 0 to 100 km/h

Off the line, the 911 GT3 RS hits 100 km/h in 3.26 s versus 4.15 s for the Cayenne Turbo. At this point, the 911 GT3 RS leads by 0.89 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 GT3 RS is doing 169 km/h against 153 km/h for the Cayenne Turbo. The gap is 0.81 s. The gap remains stable from the start.

At 400 metres standing start, the 911 GT3 RS crosses the line in 11.02 s versus 12.23 s. The 1.21 s gap represents roughly 62 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 GT3 RS continues to build its lead. At 600 metres, it runs at 235 km/h versus 212 km/h. At 1,000 metres, the 911 GT3 RS finishes in 19.95 s versus 22.17 s, with a 2.22 s lead.

What the numbers don’t tell you

Electronically capped at 278 km/h, the Cayenne Turbo 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 (4.20 kg/hp vs 2.80 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.17 seconds. The 0.89 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
