Panamera Turbo S vs Seal 390 AWD: chronicle of a drag race at 280 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 3.85 s for the Panamera Turbo S. The instant torque of 670 Nm from the electric motor makes the difference. The 0.08 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Seal 390 AWD is doing 155 km/h against 151 km/h for the Panamera Turbo S. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the Seal 390 AWD crosses the line in 11.93 s versus 12.05 s. The 0.12 s gap represents roughly 6 m of track — barely a car length.
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 Panamera Turbo S keeps accelerating towards 280 km/h. At 600 metres, the gap has dropped to 0.22 s.
Around 500 metres, both vehicles are level. This is the inversion point: the Panamera Turbo S overcomes its launch deficit thanks to a 100 km/h higher top speed.
At 1,000 metres, the Panamera Turbo S finishes in 22.19 s versus 23.93 s. The 1.74 s delta in favour of the Panamera Turbo S shows that top speed makes a clear difference.
What the numbers don’t tell you
On paper, the Panamera Turbo S combines 630 hp, 820 Nm and 1,995 kg — a clear theoretical edge over the Seal 390 AWD. Yet the Seal 390 AWD launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Seal 390 AWD has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
Both rivals are electronically governed, but not at the same level: the Panamera Turbo S is capped at 306 km/h, the Seal 390 AWD at 180 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 5.95 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Seal 390 AWD is slightly faster than the Porsche Panamera Turbo S to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
