The start: 0 to 100 km/h

Off the line, the Cayenne Turbo S hits 100 km/h in 4.36 s versus 5.57 s for the Q8 SUV. At this point, the Cayenne Turbo S leads by 1.21 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne Turbo S is doing 152 km/h against 131 km/h for the Q8 SUV. The gap is 0.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo S crosses the line in 12.42 s versus 13.90 s. The 1.48 s gap represents roughly 65 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 181 km/h. At 1,000 metres, the Cayenne Turbo S finishes in 22.41 s versus 25.53 s, with a 3.12 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Cayenne Turbo S is capped at 282 km/h, the Q8 SUV at 250 (i.e. 155 mph - industry threshold) 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 (3.81 kg/hp vs 6.18 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.84 seconds. The 1.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
