Porsche Cayenne S 958.2 vs Porsche Macan S 95B.1: which is truly faster?

Off the line, the Cayenne S hits 100 km/h in 5.13 s versus 5.37 s for the Macan S. At this point, the Cayenne S leads by 0.25 s and sits roughly 4 m ahead.

At 200 metres, the Cayenne S is doing 137 km/h against 135 km/h for the Macan S. The gap is 0.17 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne S crosses the line in 13.45 s versus 13.65 s. The 0.20 s gap represents roughly 10 m of track — barely a car length.

Past 400 metres, the Cayenne S continues to build its lead. At 600 metres, it runs at 191 km/h versus 188 km/h. At 1,000 metres, the Cayenne S finishes in 24.50 s versus 24.85 s, with a 0.35 s lead. Both vehicles have similar top speeds (251 (i.e. 155 mph — industry threshold) vs 251 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 257 km/h, the Macan S at 251 (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 (4.96 kg/hp vs 5.49 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.35 seconds. The 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
