Porsche 2013 Panamera GTS 970.1 vs Porsche Cayenne S E-Hybrid 958.2: which is truly faster?

Off the line, the 2013 Panamera GTS hits 100 km/h in 4.48 s versus 5.57 s for the Cayenne S E-Hybrid. Despite lacking instant torque, 430 hp of power compensates. At this point, the 2013 Panamera GTS leads by 1.10 s and sits roughly 4 m ahead.

At 200 metres, the 2013 Panamera GTS is doing 147 km/h against 131 km/h for the Cayenne S E-Hybrid. The gap is 0.60 s. The challenger starts to claw back ground.

At 400 metres standing start, the 2013 Panamera GTS crosses the line in 12.69 s versus 13.82 s. The 1.13 s gap represents roughly 50 m of track - a gap visible to the naked eye.

Past 400 metres, the 2013 Panamera GTS continues to build its lead. At 600 metres, it runs at 205 km/h versus 180 km/h. At 1,000 metres, the 2013 Panamera GTS finishes in 22.94 s versus 25.54 s, with a 2.60 s lead.

Both rivals are electronically governed, but not at the same level: the 2013 Panamera GTS is capped at 288 km/h, the Cayenne S E-Hybrid at 243 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.

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 8.76 seconds. The 1.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
