Porsche Cayenne Diesel 958.2 vs Porsche Macan 95B.2: which is truly faster?

Off the line, the Macan hits 100 km/h in 6.29 s versus 7.11 s for the Cayenne Diesel. At this point, the Macan leads by 0.82 s and sits roughly 6 m ahead.

At 200 metres, the Macan is doing 125 km/h against 118 km/h for the Cayenne Diesel. The gap is 0.39 s. The challenger starts to claw back ground.

At 400 metres standing start, the Macan crosses the line in 14.56 s versus 15.22 s. The 0.66 s gap represents roughly 27 m of track - two to three car lengths.

Past 400 metres, the Macan continues to build its lead. At 600 metres, it runs at 171 km/h versus 163 km/h. At 1,000 metres, the Macan finishes in 26.84 s versus 28.17 s, with a 1.34 s lead. Both vehicles have similar top speeds (217 vs 229 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne Diesel is capped at 217 km/h, the Macan at 229 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 (8.05 kg/hp vs 7.59 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.83 seconds. The 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
