Porsche Cayenne Turbo Coupe vs Tesla Model Y Juniper Long Range AWD: which is truly faster?

Off the line, the Cayenne Turbo Coupe hits 100 km/h in 3.84 s versus 4.55 s for the Model Y Juniper Long Range AWD. Despite lacking instant torque, 520 hp of power compensates. At this point, the Cayenne Turbo Coupe leads by 0.71 s and sits roughly 13 m ahead.

At 200 metres, the Cayenne Turbo Coupe is doing 150 km/h against 145 km/h for the Model Y Juniper Long Range AWD. The gap is 0.60 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo Coupe crosses the line in 12.07 s versus 12.83 s. The 0.76 s gap represents roughly 37 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne Turbo Coupe continues to build its lead. At 600 metres, it runs at 206 km/h versus 199 km/h. At 1,000 metres, the Cayenne Turbo Coupe finishes in 22.22 s versus 23.43 s, with a 1.20 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne Turbo Coupe is capped at 285 km/h, the Model Y Juniper Long Range AWD 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 6.83 seconds. The 0.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
