Model 3 Performance vs 911 Carrera 4 Cabriolet: chronicle of a drag race at 283 km/h
The launch: 0 to 100 km/h
Off the line, the Model 3 Performance hits 100 km/h in 3.36 s versus 4.37 s for the 911 Carrera 4 Cabriolet. The instant torque of 713 Nm from the electric motor makes the difference. At this point, the Model 3 Performance leads by 1.01 s and sits roughly 13 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Model 3 Performance is doing 156 km/h against 152 km/h for the 911 Carrera 4 Cabriolet. The gap is 0.76 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model 3 Performance crosses the line in 11.57 s versus 12.42 s. The 0.84 s gap represents roughly 43 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Model 3 Performance continues to build its lead. At 600 metres, it runs at 215 km/h versus 212 km/h. At 1,000 metres, the Model 3 Performance finishes in 21.35 s versus 22.38 s, with a 1.03 s lead. Despite a higher top speed (283 km/h), the 911 Carrera 4 Cabriolet never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Model 3 Performance is capped at 261 km/h, the 911 Carrera 4 Cabriolet at 288 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 6.40 seconds. The 1.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model 3 Performance has a clear edge over the Porsche 911 Carrera 4 Cabriolet to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
