911 Turbo S Cabriolet vs Model Y Performance: chronicle of a drag race at 312 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Turbo S Cabriolet hits 100 km/h in 3.30 s versus 3.76 s for the Model Y Performance. Despite lacking instant torque, 537 hp of power compensates. At this point, the 911 Turbo S Cabriolet leads by 0.46 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Turbo S Cabriolet is doing 170 km/h against 152 km/h for the Model Y Performance. The gap is 0.50 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Turbo S Cabriolet crosses the line in 11.04 s versus 12.01 s. The 0.97 s gap represents roughly 49 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Turbo S Cabriolet continues to build its lead. At 600 metres, it runs at 235 km/h versus 209 km/h. At 1,000 metres, the 911 Turbo S Cabriolet finishes in 20.00 s versus 22.06 s, with a 2.06 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Turbo S Cabriolet is capped at 312 km/h, the Model Y Performance at 249 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 5.73 seconds. The 0.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Turbo S Cabriolet is slightly faster than the Tesla Model Y Performance to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
