Porsche Cayenne GTS E3.1 vs Porsche Macan S 95B.1: which is truly faster?

Off the line, the Cayenne GTS hits 100 km/h in 4.37 s versus 5.28 s for the Macan S. At this point, the Cayenne GTS leads by 0.91 s and sits roughly 15 m ahead.

At 200 metres, the Cayenne GTS is doing 142 km/h against 138 km/h for the Macan S. The gap is 0.72 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne GTS crosses the line in 12.66 s versus 13.52 s. The 0.86 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne GTS continues to build its lead. At 600 metres, it runs at 197 km/h versus 190 km/h. At 1,000 metres, the Cayenne GTS finishes in 23.37 s versus 24.59 s, with a 1.22 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne GTS is capped at 270 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 (4.88 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 8.00 seconds. The 0.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
