The start: 0 to 100 km/h

Off the line, the S8 hits 100 km/h in 3.83 s versus 5.81 s for the Cayenne S. At this point, the S8 leads by 1.98 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S8 is doing 157 km/h against 133 km/h for the Cayenne S. The gap is 1.41 s. The challenger starts to claw back ground.

At 400 metres standing start, the S8 crosses the line in 11.81 s versus 13.99 s. The 2.18 s gap represents roughly 96 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 186 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 25.30 s, with a 4.04 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 258 km/h), preventing any comeback.

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 S at 258 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 5.16 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.88 seconds. The 1.98 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
