BYD Seal 390 AWD vs Porsche Panamera 971: which is truly faster?

Off the line, the Seal 390 AWD hits 100 km/h in 3.77 s versus 5.28 s for the Panamera. The instant torque of 670 Nm from the electric motor makes the difference. At this point, the Seal 390 AWD leads by 1.51 s and sits roughly 12 m ahead.

At 200 metres, the Seal 390 AWD is doing 155 km/h against 136 km/h for the Panamera. The gap is 1.13 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 13.57 s. The 1.64 s gap represents roughly 75 m of track — a gap visible to the naked eye.

Past 400 metres, the gap narrows. The Seal 390 AWD maxes out at 180 km/h while the Panamera keeps accelerating towards 264 km/h. At 600 metres, the gap has dropped to 1.65 s.

At 1,000 metres, the Seal 390 AWD finishes in 23.93 s versus 24.66 s, with just 0.73 s to spare. The Panamera fails to fully close the launch gap.

The Seal 390 AWD features all-wheel drive (AWD) against the Panamera’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the Seal 390 AWD is capped at 180 km/h, the Panamera at 264 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 8.22 seconds. The 1.51 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
