The start: 0 to 100 km/h

Off the line, the Cayenne S E-Hybrid hits 100 km/h in 5.57 s versus 5.83 s for the G 450 d. The instant torque of 590 Nm from the electric motor makes the difference. At this point, the Cayenne S E-Hybrid leads by 0.26 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayenne S E-Hybrid is doing 131 km/h against 128 km/h for the G 450 d. The gap is 0.16 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne S E-Hybrid crosses the line in 13.82 s versus 14.11 s. The 0.29 s gap represents roughly 12 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayenne S E-Hybrid continues to build its lead. At 600 metres, it runs at 180 km/h versus 174 km/h. At 1,000 metres, the Cayenne S E-Hybrid finishes in 25.54 s versus 26.22 s, with a 0.68 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Cayenne S E-Hybrid is capped at 243 km/h, the G 450 d at 210 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 9.41 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
