The start: 0 to 100 km/h

Off the line, the Q8 SUV hits 100 km/h in 5.57 s versus 6.29 s for the Cayenne S Hybrid. At this point, the Q8 SUV leads by 0.72 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Q8 SUV is doing 131 km/h against 125 km/h for the Cayenne S Hybrid. The gap is 0.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the Q8 SUV crosses the line in 13.90 s versus 14.49 s. The 0.59 s gap represents roughly 25 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Q8 SUV continues to build its lead. At 600 metres, it runs at 181 km/h versus 171 km/h. At 1,000 metres, the Q8 SUV finishes in 25.53 s versus 26.81 s, with a 1.28 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Cayenne S Hybrid is capped at 242 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 (5.82 kg/hp vs 6.18 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.10 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
