Porsche Cayenne GTS 958.1 vs KIA EV6 AWD Long Range: which is truly faster?

Off the line, the EV6 AWD Long Range hits 100 km/h in 5.16 s versus 5.56 s for the Cayenne GTS. The instant torque of 605 Nm from the electric motor makes the difference. At this point, the EV6 AWD Long Range leads by 0.40 s and sits roughly 6 m ahead.

At 200 metres, the EV6 AWD Long Range is doing 135 km/h against 137 km/h for the Cayenne GTS. The gap is 0.23 s. The challenger starts to claw back ground.

At 400 metres standing start, the EV6 AWD Long Range crosses the line in 13.61 s versus 13.70 s. The 0.09 s gap represents roughly 4 m of track - barely a car length.

Past 400 metres, the situation changes. The EV6 AWD Long Range maxes out at 185 km/h while the Cayenne GTS keeps accelerating towards 261 km/h. At 600 metres, the gap has dropped to 0.09 s.

Around 502 metres, both vehicles are level. This is the inversion point: the Cayenne GTS overcomes its launch deficit thanks to a 76 km/h higher top speed.

At 1,000 metres, the Cayenne GTS finishes in 24.70 s versus 25.54 s. The 0.84 s delta in favour of the Cayenne GTS shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the Cayenne GTS is capped at 261 km/h, the EV6 AWD Long Range at 185 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 8.33 seconds. The 0.40 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
