Both rivals are electronically governed, but not at the same level: the Cayenne Platinum Edition is capped at 229 km/h, the Cayenne Diesel Platinum Edition at 217 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 (6.68 kg/hp vs 8.95 kg/hp) and transmission (auto vs auto).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.42 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
