Bmw X7 M50i vs Taycan with Performance Battery Plus (PB): chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw X7 M50i hits 100 km/h in 4.74 s versus 5.24 s for the Taycan with Performance Battery Plus (PB). Despite lacking instant torque, 530 hp of power compensates. At this point, the Bmw X7 M50i leads by 0.50 s and sits roughly 10 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw X7 M50i is doing 144 km/h against 148 km/h for the Taycan with Performance Battery Plus (PB). The gap is 0.32 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X7 M50i crosses the line in 12.92 s versus 13.07 s. The 0.15 s gap represents roughly 8 m of track — barely a car length.
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 Bmw X7 M50i keeps accelerating towards 250 km/h. At 600 metres, the gap has dropped to 0.10 s.
Around 524 metres, both vehicles are level. This is the inversion point: the Taycan with Performance Battery Plus (PB) overcomes its launch deficit thanks to a 20 km/h higher top speed.
At 1,000 metres, the Taycan with Performance Battery Plus (PB) finishes in 22.91 s versus 23.38 s. The 0.47 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 Bmw X7 M50i is capped at 250 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.
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 7.09 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw X7 M50i 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.
