Audi SQ6 SUV e-tron vs Porsche Cayenne GTS E3.1: which is truly faster?

Off the line, the SQ6 SUV e-tron hits 100 km/h in 4.37 s versus 4.37 s for the Cayenne GTS. The instant torque of 855 Nm from the electric motor makes the difference. The 0.00 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Cayenne GTS is doing 142 km/h against 144 km/h for the SQ6 SUV e-tron. The gap is 0.10 s. The gap widens compared to the 0-100.

At 400 metres standing start, the Cayenne GTS crosses the line in 12.66 s versus 12.70 s. The 0.04 s gap represents roughly 2 m of track

Past 400 metres, the situation changes. The SQ6 SUV e-tron maxes out at 230 km/h while the Cayenne GTS keeps accelerating towards 266 km/h. At 600 metres, the gap has dropped to 0.00 s.

Around 625 metres, both vehicles are level. This is the inversion point: the SQ6 SUV e-tron overcomes its launch deficit thanks to a 36 km/h higher top speed.

At 1,000 metres, the SQ6 SUV e-tron finishes in 23.29 s versus 23.37 s. The 0.08 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the SQ6 SUV e-tron is capped at 230 km/h, the Cayenne GTS at 270 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 6.93 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
