X9 vs Taycan with Performance Battery Plus (PB): chronicle of a drag race at 230 km/h
The launch: 0 to 100 km/h
Off the line, the X9 hits 100 km/h in 3.88 s versus 5.24 s for the Taycan with Performance Battery Plus (PB). At this point, the X9 leads by 1.36 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the X9 is doing 173 km/h against 148 km/h for the Taycan with Performance Battery Plus (PB). The gap is 1.22 s. The challenger starts to claw back ground.
At 400 metres standing start, the X9 crosses the line in 11.34 s versus 13.07 s. The 1.74 s gap represents roughly 88 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 Taycan with Performance Battery Plus (PB) keeps accelerating towards 230 km/h. At 600 metres, the gap has dropped to 1.67 s.
At 1,000 metres, the X9 finishes in 22.13 s versus 22.91 s, with just 0.78 s to spare. The Taycan with Performance Battery Plus (PB) 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 Taycan with Performance Battery Plus (PB) at 230 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 (2.46 kg/hp vs 4.59 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.09 seconds. The 1.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Xpeng X9 has a clear edge over the Porsche Taycan with Performance Battery Plus (PB) to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
