Model Y Juniper Long Range AWD vs Cayman S (Manual): chronicle of a drag race at 286 km/h
The launch: 0 to 100 km/h
Off the line, the Model Y Juniper Long Range AWD hits 100 km/h in 4.55 s versus 4.97 s for the Cayman S (Manual). The instant torque of 588 Nm from the electric motor makes the difference. At this point, the Model Y Juniper Long Range AWD leads by 0.42 s and sits roughly 5 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Model Y Juniper Long Range AWD is doing 145 km/h against 148 km/h for the Cayman S (Manual). The gap is 0.23 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model Y Juniper Long Range AWD crosses the line in 12.83 s versus 12.90 s. The 0.08 s gap represents roughly 4 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Model Y Juniper Long Range AWD maxes out at 217 km/h while the Cayman S (Manual) keeps accelerating towards 286 km/h. At 600 metres, the gap has dropped to 0.10 s.
Around 480 metres, both vehicles are level. This is the inversion point: the Cayman S (Manual) overcomes its launch deficit thanks to a 69 km/h higher top speed.
At 1,000 metres, the Cayman S (Manual) finishes in 22.95 s versus 23.43 s. The 0.48 s delta shows an extremely tight race.
What the numbers don’t tell you
Electronically capped at 217 km/h, the Model Y Juniper Long Range AWD never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
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 7.17 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model Y Juniper Long Range AWD has a clear edge over the Porsche Cayman S (Manual) to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
