Model X 90D vs 911 Targa 4 GTS: chronicle of a drag race at 307 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Targa 4 GTS hits 100 km/h in 3.66 s versus 5.03 s for the Model X 90D. Despite lacking instant torque, 456 hp of power compensates. At this point, the 911 Targa 4 GTS leads by 1.38 s and sits roughly 16 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Targa 4 GTS is doing 162 km/h against 147 km/h for the Model X 90D. The gap is 1.11 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4 GTS crosses the line in 11.57 s versus 13.07 s. The 1.50 s gap represents roughly 74 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Targa 4 GTS continues to build its lead. At 600 metres, it runs at 224 km/h versus 205 km/h. At 1,000 metres, the 911 Targa 4 GTS finishes in 20.93 s versus 23.32 s, with a 2.38 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Model X 90D is capped at 249 km/h, the 911 Targa 4 GTS at 307 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 7.09 seconds. The 1.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Targa 4 GTS has a clear edge over the Tesla Model X 90D to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
