X9 vs Panamera GTS Sport Turismo: chronicle of a drag race at 287 km/h
The launch: 0 to 100 km/h
Off the line, the X9 hits 100 km/h in 3.88 s versus 3.94 s for the Panamera GTS Sport Turismo. The instant torque of 717 Nm from the electric motor makes the difference. The 0.06 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 150 km/h for the Panamera GTS Sport Turismo. The gap is 0.29 s. The gap widens compared to the 0-100.
At 400 metres standing start, the X9 crosses the line in 11.34 s versus 12.16 s. The 0.82 s gap represents roughly 41 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 GTS Sport Turismo keeps accelerating towards 287 km/h. At 600 metres, the gap has dropped to 0.87 s.
At 1,000 metres, the X9 finishes in 22.13 s versus 22.25 s, with just 0.12 s to spare. The Panamera GTS Sport Turismo 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 X9 is capped at 200 km/h, the Panamera GTS Sport Turismo at 288 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 6.12 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Xpeng X9 is slightly faster than the Porsche Panamera GTS Sport Turismo to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
