Model X 90D vs Taycan 4 Cross Turismo: chronicle of a drag race at 249 km/h
The launch: 0 to 100 km/h
Off the line, the Taycan 4 Cross Turismo hits 100 km/h in 4.84 s versus 5.03 s for the Model X 90D. At this point, the Taycan 4 Cross Turismo leads by 0.20 s and sits roughly 5 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Taycan 4 Cross Turismo is doing 144 km/h against 147 km/h for the Model X 90D. The gap is 0.13 s. The gap remains stable from the start.
At 400 metres standing start, the Taycan 4 Cross Turismo crosses the line in 13.02 s versus 13.07 s. The 0.05 s gap represents roughly 2 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Taycan 4 Cross Turismo maxes out at 219 km/h while the Model X 90D keeps accelerating towards 249 km/h. At 600 metres, the gap has dropped to 0.00 s.
Around 585 metres, both vehicles are level. This is the inversion point: the Model X 90D overcomes its launch deficit thanks to a 30 km/h higher top speed.
At 1,000 metres, the Model X 90D finishes in 23.32 s versus 23.49 s. The 0.17 s delta shows an extremely tight race.
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 Taycan 4 Cross Turismo at 219 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (4.59 kg/hp vs 4.86 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.23 seconds. The 0.20 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model X 90D and Porsche Taycan 4 Cross Turismo are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
