The start: 0 to 100 km/h

Off the line, the RS Q8 SUV hits 100 km/h in 3.66 s versus 5.63 s for the Cayenne. At this point, the RS Q8 SUV leads by 1.97 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the RS Q8 SUV is doing 161 km/h against 133 km/h for the Cayenne. The gap is 1.43 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS Q8 SUV crosses the line in 11.58 s versus 13.87 s. The 2.28 s gap represents roughly 100 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the RS Q8 SUV continues to build its lead. At 600 metres, it runs at 223 km/h versus 184 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.01 s versus 25.36 s, with a 4.35 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the RS Q8 SUV is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Cayenne at 245 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 (3.55 kg/hp vs 5.84 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.70 seconds. The 1.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
