BYD Seal 390 AWD vs Porsche Macan GTS: which is truly faster?

Off the line, the Seal 390 AWD hits 100 km/h in 3.77 s versus 4.49 s for the Macan GTS. The instant torque of 670 Nm from the electric motor makes the difference. At this point, the Seal 390 AWD leads by 0.72 s and sits roughly 6 m ahead.

At 200 metres, the Seal 390 AWD is doing 155 km/h against 147 km/h for the Macan GTS. The gap is 0.52 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 12.61 s. The 0.67 s gap represents roughly 34 m of track - a gap visible to the naked eye.

Past 400 metres, the situation changes. The Seal 390 AWD maxes out at 180 km/h while the Macan GTS keeps accelerating towards 272 km/h. At 600 metres, the gap has dropped to 0.36 s.

Around 722 metres, both vehicles are level. This is the inversion point: the Macan GTS overcomes its launch deficit thanks to a 92 km/h higher top speed.

At 1,000 metres, the Macan GTS finishes in 22.79 s versus 23.93 s. The 1.14 s delta in favour of the Macan GTS shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the Seal 390 AWD is capped at 180 km/h, the Macan GTS at 272 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 6.65 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
