Model X 90D vs Taycan with Performance Battery Plus (PB): chronicle of a drag race at 249 km/h
The launch: 0 to 100 km/h
Off the line, the Model X 90D hits 100 km/h in 5.03 s versus 5.24 s for the Taycan with Performance Battery Plus (PB). At this point, the Model X 90D leads by 0.21 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Model X 90D is doing 147 km/h against 148 km/h for the Taycan with Performance Battery Plus (PB). The gap is 0.11 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model X 90D crosses the line in 13.07 s versus 13.07 s. The 0.01 s gap represents roughly 0 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Taycan with Performance Battery Plus (PB) maxes out at 230 km/h while the Model X 90D keeps accelerating towards 249 km/h. At 600 metres, the gap has dropped to 0.18 s.
Around 407 metres, both vehicles are level. This is the inversion point: the Taycan with Performance Battery Plus (PB) overcomes its launch deficit thanks to a 19 km/h higher top speed.
At 1,000 metres, the Taycan with Performance Battery Plus (PB) finishes in 22.91 s versus 23.32 s. The 0.40 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 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 (4.59 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 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Tesla Model X 90D is slightly faster than the Porsche Taycan with Performance Battery Plus (PB) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
