Audi RS e-tron GT vs Porsche Panamera Turbo 970.1: which is truly faster?

Off the line, the RS e-tron GT hits 100 km/h in 3.33 s versus 3.92 s for the Panamera Turbo. The instant torque of 830 Nm from the electric motor makes the difference. At this point, the RS e-tron GT leads by 0.59 s and sits roughly 5 m ahead.

At 200 metres, the RS e-tron GT is doing 163 km/h against 153 km/h for the Panamera Turbo. The gap is 0.47 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS e-tron GT crosses the line in 11.31 s versus 12.01 s. The 0.70 s gap represents roughly 37 m of track - a gap visible to the naked eye.

Past 400 metres, the RS e-tron GT continues to build its lead. At 600 metres, it runs at 227 km/h versus 213 km/h. At 1,000 metres, the RS e-tron GT finishes in 20.60 s versus 21.90 s, with a 1.30 s lead. Despite a higher top speed (293 km/h), the Panamera Turbo never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the RS e-tron GT is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Panamera Turbo at 303 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 5.84 seconds. The 0.59 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
