CONFIDENCE 91%The Model Y reaches 100 km/h first (3.76 s vs 3.95 s), but the Cayman GT4 is ahead at every metre of the race. Explanation: the Cayman GT4 accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Tesla Model Y Performance is faster at 0-100 km/h, but the Porsche Cayman GT4 compensates at high speed thanks to higher peak power or top speed. At 400 m, Porsche Cayman GT4 leads by 0.12 s.

Model Y Performance vs Cayman GT4: chronicle of a drag race at 295 km/h
The launch: 0 to 100 km/h
Off the line, the Model Y Performance hits 100 km/h in 3.76 s versus 3.95 s for the Cayman GT4. The instant torque of 670 Nm from the electric motor makes the difference. The 0.19 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Model Y Performance is doing 152 km/h against 155 km/h for the Cayman GT4. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayman GT4 crosses the line in 11.90 s versus 12.01 s. The 0.12 s gap represents roughly 6 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Cayman GT4 continues to build its lead. At 600 metres, it runs at 218 km/h versus 209 km/h. At 1,000 metres, the Cayman GT4 finishes in 21.59 s versus 22.06 s, with a 0.47 s lead.
What the numbers don’t tell you
Electronically capped at 249 km/h, the Model Y Performance 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 5.92 seconds. The 0.19 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model Y Performance is slightly faster than the Porsche Cayman GT4 to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
