Model X Long Range vs 911 Turbo S Cabriolet: chronicle of a drag race at 318 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Turbo S Cabriolet hits 100 km/h in 2.95 s versus 4.11 s for the Model X Long Range. Despite lacking instant torque, 560 hp of power compensates. At this point, the 911 Turbo S Cabriolet leads by 1.16 s and sits roughly 13 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Turbo S Cabriolet is doing 173 km/h against 160 km/h for the Model X Long Range. The gap is 0.97 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Turbo S Cabriolet crosses the line in 10.67 s versus 11.92 s. The 1.26 s gap represents roughly 68 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 238 km/h versus 224 km/h. At 1,000 metres, the 911 Turbo S Cabriolet finishes in 19.48 s versus 21.31 s, with a 1.83 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Model X Long Range is capped at 249 km/h, the 911 Turbo S Cabriolet at 318 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 5.65 seconds. The 1.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Turbo S Cabriolet has a clear edge over the Tesla Model X Long Range to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
