Tesla Model S Long Range vs Porsche Panamera GTS 971: which is truly faster?

Off the line, the Model S Long Range hits 100 km/h in 3.29 s versus 3.93 s for the Panamera GTS. The instant torque of 908 Nm from the electric motor makes the difference. At this point, the Model S Long Range leads by 0.63 s and sits roughly 5 m ahead.

At 200 metres, the Model S Long Range is doing 167 km/h against 151 km/h for the Panamera GTS. The gap is 0.58 s. The gap remains stable from the start.

At 400 metres standing start, the Model S Long Range crosses the line in 11.11 s versus 12.12 s. The 1.01 s gap represents roughly 51 m of track — a gap visible to the naked eye.

Past 400 metres, the Model S Long Range continues to build its lead. At 600 metres, it runs at 236 km/h versus 210 km/h. At 1,000 metres, the Model S Long Range finishes in 20.17 s versus 22.14 s, with a 1.97 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 Model S Long Range 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 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
