Porsche Cayenne S E-Hybrid vs Renault Rafale E-Tech Full Hybrid 4x4 300: which is truly faster?

Off the line, the Cayenne S E-Hybrid hits 100 km/h in 5.57 s versus 5.68 s for the Rafale E-Tech Full Hybrid 4x4 300. The instant torque of 590 Nm from the electric motor makes the difference. At this point, the Cayenne S E-Hybrid leads by 0.11 s and sits roughly 7 m ahead.

At 200 metres, the Cayenne S E-Hybrid is doing 131 km/h against 133 km/h for the Rafale E-Tech Full Hybrid 4x4 300. The gap is 0.20 s. The gap widens compared to the 0-100.

At 400 metres standing start, the Cayenne S E-Hybrid crosses the line in 13.82 s versus 13.92 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.

Past 400 metres, the situation changes. The Rafale E-Tech Full Hybrid 4x4 300 maxes out at 200 km/h while the Cayenne S E-Hybrid keeps accelerating towards 237 km/h. At 600 metres, the gap has dropped to 0.02 s.

Around 573 metres, both vehicles are level. This is the inversion point: the Rafale E-Tech Full Hybrid 4x4 300 overcomes its launch deficit thanks to a 37 km/h higher top speed.

At 1,000 metres, the Rafale E-Tech Full Hybrid 4x4 300 finishes in 25.35 s versus 25.54 s. The 0.19 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the Cayenne S E-Hybrid is capped at 243 km/h, the Rafale E-Tech Full Hybrid 4x4 300 at 200 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 8.76 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
