The start: 0 to 100 km/h

Off the line, the G6 hits 100 km/h in 3.80 s versus 4.74 s for the Cayenne E-Hybrid. At this point, the G6 leads by 0.94 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the G6 is doing 152 km/h against 141 km/h for the Cayenne E-Hybrid. The gap is 0.65 s. The challenger starts to claw back ground.

At 400 metres standing start, the G6 crosses the line in 12.03 s versus 13.01 s. The 0.98 s gap represents roughly 47 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The G6 maxes out at 200 km/h while the Cayenne E-Hybrid keeps accelerating towards 253 km/h. At 600 metres, the gap is down to 1.22 s from 0.98 s at 400 metres.

At 1,000 metres, the G6 finishes in 22.89 s versus 23.81 s, with just 0.92 s to spare. The Cayenne E-Hybrid fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the G6 is capped at 200 km/h, the Cayenne E-Hybrid at 253 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (4.41 kg/hp vs 4.98 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.35 seconds. The 0.94 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
