Porsche Taycan 4S J1.1 vs Porsche Panamera GTS 971: which is truly faster?

Off the line, the Panamera GTS hits 100 km/h in 3.93 s versus 3.93 s for the Taycan 4S. Despite lacking instant torque, 460 hp of power compensates. The 0.01 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Panamera GTS is doing 151 km/h against 153 km/h for the Taycan 4S. The gap is 0.01 s. The gap remains stable from the start.

At 400 metres standing start, the Taycan 4S crosses the line in 12.06 s versus 12.12 s. The 0.05 s gap represents roughly 3 m of track - barely a car length.

Past 400 metres, the Taycan 4S continues to build its lead. At 600 metres, it runs at 215 km/h versus 210 km/h. At 1,000 metres, the Taycan 4S finishes in 21.83 s versus 22.14 s, with a 0.31 s lead. Despite a higher top speed (289 km/h), the Panamera GTS never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the Taycan 4S is capped at 249 (i.e. 155 mph - industry threshold) km/h, the Panamera GTS at 291 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 6.06 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
