The start: 0 to 100 km/h

Off the line, the Cayenne Turbo S hits 100 km/h in 3.96 s versus 6.58 s for the P7. Despite lacking instant torque, 570 hp of power compensates. At this point, the Cayenne Turbo S leads by 2.62 s and sits roughly 22 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne Turbo S is doing 152 km/h against 127 km/h for the P7. The gap is 1.85 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo S crosses the line in 12.11 s versus 14.81 s. The 2.70 s gap represents roughly 112 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayenne Turbo S continues to build its lead. At 600 metres, it runs at 211 km/h versus 170 km/h. At 1,000 metres, the Cayenne Turbo S finishes in 22.13 s versus 27.64 s, with a 5.51 s lead.

What the numbers don’t tell you

The Cayenne Turbo S features all-wheel drive (AWD) against the P7’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 Cayenne Turbo S is capped at 283 km/h, the P7 at 170 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.18 seconds. The 2.62 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
