The start: 0 to 100 km/h

Off the line, the Model X P100D hits 100 km/h in 3.05 s versus 7.43 s for the Cayenne Diesel. The instant torque of 967 Nm from the electric motor makes the difference. At this point, the Model X P100D leads by 4.38 s and sits roughly 18 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Model X P100D is doing 167 km/h against 117 km/h for the Cayenne Diesel. The gap is 2.82 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model X P100D crosses the line in 10.97 s versus 15.43 s. The 4.46 s gap represents roughly 166 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Model X P100D continues to build its lead. At 600 metres, it runs at 231 km/h versus 161 km/h. At 1,000 metres, the Model X P100D finishes in 20.13 s versus 28.50 s, with a 8.38 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Model X P100D is capped at 249 (i.e. 155 mph - industry threshold) km/h, the Cayenne Diesel at 217 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 12.32 seconds. The 4.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
