CONFIDENCE 94%Why this result?
The Porsche Panamera Turbo S is faster at 0-100 km/h, but the Xpeng X9 compensates at high speed thanks to higher peak power or top speed. At 400 m, Xpeng X9 leads by 0.72 s.

Panamera Turbo S vs X9: chronicle of a drag race at 280 km/h
The launch: 0 to 100 km/h
Off the line, the Panamera Turbo S hits 100 km/h in 3.85 s versus 3.88 s for the X9. Despite lacking instant torque, 630 hp of power compensates. The 0.03 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the X9 is doing 173 km/h against 151 km/h for the Panamera Turbo S. The gap is 0.21 s. The gap widens compared to the 0-100.
At 400 metres standing start, the X9 crosses the line in 11.34 s versus 12.05 s. The 0.71 s gap represents roughly 36 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The X9 maxes out at 200 km/h while the Panamera Turbo S keeps accelerating towards 280 km/h. At 600 metres, the gap has dropped to 0.77 s.
At 1,000 metres, the X9 finishes in 22.13 s versus 22.19 s, with just 0.06 s to spare. The Panamera Turbo S fails to fully close the launch gap.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Panamera Turbo S is capped at 306 km/h, the X9 at 200 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 5.95 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Panamera Turbo S and Xpeng X9 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.
