Seal 390 AWD vs Cayenne GTS Coupe: chronicle of a drag race at 266 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 4.35 s for the Cayenne GTS Coupe. The instant torque of 670 Nm from the electric motor makes the difference. The 0.58 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 142 km/h for the Cayenne GTS Coupe. The gap is 0.37 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 12.64 s. The 0.71 s gap represents roughly 34 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 Cayenne GTS Coupe keeps accelerating towards 266 km/h. At 600 metres, the gap has dropped to 0.56 s.
Around 831 metres, both vehicles are level. This is the inversion point: the Cayenne GTS Coupe overcomes its launch deficit thanks to a 86 km/h higher top speed.
At 1,000 metres, the Cayenne GTS Coupe finishes in 23.34 s versus 23.93 s. The 0.59 s delta in favour of the Cayenne GTS Coupe 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 Cayenne GTS Coupe at 270 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 6.90 seconds. The 0.58 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 Cayenne GTS Coupe to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
