Porsche Cayenne S E3.1 vs Audi S5 Sedan : which one is faster?
0-100 km/h, 400 m, 1000 m, top speed — physics simulation calibrated on 7 measures.

Race simulation at real speed
CONFIDENCE 93%The S5 Sedan reaches 100 km/h first (4.50 s vs 4.63 s), but the Cayenne S is ahead at every metre of the race. Explanation: the Cayenne S accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Audi S5 Sedan is faster at 0-100 km/h, but the Porsche Cayenne S compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche Cayenne S leads by 0.01 s.

Cayenne S vs S5 Sedan: chronicle of a drag race at 264 km/h
The launch: 0 to 100 km/h
Off the line, the S5 Sedan hits 100 km/h in 4.50 s versus 4.64 s for the Cayenne S. At this point, the S5 Sedan leads by 0.13 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the S5 Sedan is doing 142 km/h against 145 km/h for the Cayenne S. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the Cayenne S crosses the line in 12.79 s versus 12.80 s. The 0.01 s gap represents roughly 1 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayenne S continues to build its lead. At 600 metres, it runs at 202 km/h versus 198 km/h. At 1,000 metres, the Cayenne S finishes in 23.26 s versus 23.38 s, with a 0.12 s lead. Both vehicles have similar top speeds (264 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 264 km/h, the S5 Sedan at 250 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 (4.59 kg/hp vs 5.31 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Audi S5 Sedan is slightly faster than the Porsche Cayenne S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
