Seal 390 AWD 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 Seal 390 AWD hits 100 km/h in 3.77 s versus 5.24 s for the Taycan with Performance Battery Plus (PB). At this point, the Seal 390 AWD leads by 1.47 s and sits roughly 17 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Seal 390 AWD is doing 155 km/h against 148 km/h for the Taycan with Performance Battery Plus (PB). The gap is 1.06 s. The challenger starts to claw back ground.
At 400 metres standing start, the Seal 390 AWD crosses the line in 11.93 s versus 13.07 s. The 1.14 s gap represents roughly 59 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Seal 390 AWD maxes out at 180 km/h while the Taycan with Performance Battery Plus (PB) keeps accelerating towards 230 km/h. At 600 metres, the gap has dropped to 0.67 s.
Around 766 metres, both vehicles are level. This is the inversion point: the Taycan with Performance Battery Plus (PB) overcomes its launch deficit thanks to a 50 km/h higher top speed.
At 1,000 metres, the Taycan with Performance Battery Plus (PB) finishes in 22.91 s versus 23.93 s. The 1.02 s delta in favour of the Taycan with Performance Battery Plus (PB) shows that top speed makes a clear difference.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Seal 390 AWD is capped at 180 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 (4.06 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 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Seal 390 AWD 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.
