The start: 0 to 100 km/h

Off the line, the S8 hits 100 km/h in 3.83 s versus 4.35 s for the Cayenne GTS Coupe. The 0.52 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the S8 is doing 157 km/h against 142 km/h for the Cayenne GTS Coupe. The gap is 0.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the S8 crosses the line in 11.81 s versus 12.64 s. The 0.83 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S8 continues to build its lead. At 600 metres, it runs at 222 km/h versus 197 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 23.34 s, with a 2.08 s lead. Despite a higher top speed (266 km/h), the Cayenne GTS Coupe never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the S8 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Cayenne GTS Coupe at 270 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 (3.89 kg/hp vs 4.86 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.90 seconds. The 0.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
