Porsche Cayenne E-Hybrid Coupe E3.1 vs Porsche Macan S 95B.1: which is truly faster?

Off the line, the Cayenne E-Hybrid Coupe hits 100 km/h in 4.84 s versus 5.37 s for the Macan S. The instant torque of 700 Nm from the electric motor makes the difference. At this point, the Cayenne E-Hybrid Coupe leads by 0.53 s and sits roughly 9 m ahead.

At 200 metres, the Cayenne E-Hybrid Coupe is doing 139 km/h against 135 km/h for the Macan S. The gap is 0.43 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne E-Hybrid Coupe crosses the line in 13.14 s versus 13.65 s. The 0.52 s gap represents roughly 24 m of track - two to three car lengths.

Past 400 metres, the Cayenne E-Hybrid Coupe continues to build its lead. At 600 metres, it runs at 193 km/h versus 188 km/h. At 1,000 metres, the Cayenne E-Hybrid Coupe finishes in 24.06 s versus 24.85 s, with a 0.78 s lead. Both vehicles have similar top speeds (253 vs 251 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

Both rivals share the same electronic speed cap: the Cayenne E-Hybrid Coupe and the Macan S are governed to 253 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.35 seconds. The 0.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
