I-PACE EV400 vs Cayenne: chronicle of a drag race at 245 km/h
The launch: 0 to 100 km/h
Off the line, the I-PACE EV400 hits 100 km/h in 4.84 s versus 5.63 s for the Cayenne. The instant torque of 696 Nm from the electric motor makes the difference. At this point, the I-PACE EV400 leads by 0.79 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the I-PACE EV400 is doing 141 km/h against 133 km/h for the Cayenne. The gap is 0.43 s. The challenger starts to claw back ground.
At 400 metres standing start, the I-PACE EV400 crosses the line in 13.18 s versus 13.87 s. The 0.68 s gap represents roughly 31 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the I-PACE EV400 continues to build its lead. At 600 metres, it runs at 192 km/h versus 184 km/h. At 1,000 metres, the I-PACE EV400 finishes in 24.36 s versus 25.36 s, with a 1.00 s lead. Despite a higher top speed (245 km/h), the Cayenne never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the I-PACE EV400 is capped at 200 km/h, the Cayenne at 245 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 8.70 seconds. The 0.79 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Jaguar I-PACE EV400 has a clear edge over the Porsche Cayenne to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
