911 Carrera 4 vs Model Y Juniper RWD: chronicle of a drag race at 285 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4 hits 100 km/h in 4.90 s versus 6.04 s for the Model Y Juniper RWD. Despite lacking instant torque, 355 hp of power compensates. At this point, the 911 Carrera 4 leads by 1.15 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4 is doing 147 km/h against 135 km/h for the Model Y Juniper RWD. The gap is 0.91 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera 4 crosses the line in 12.85 s versus 14.24 s. The 1.39 s gap represents roughly 62 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera 4 continues to build its lead. At 600 metres, it runs at 209 km/h versus 185 km/h. At 1,000 metres, the 911 Carrera 4 finishes in 22.96 s versus 25.58 s, with a 2.62 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera 4 is capped at 285 km/h, the Model Y Juniper RWD at 209 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 8.90 seconds. The 1.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera 4 has a clear edge over the Tesla Model Y Juniper RWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
