Seal 390 AWD vs 911 Carrera GTS (MT): chronicle of a drag race at 311 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 4.13 s for the 911 Carrera GTS (MT). The instant torque of 670 Nm from the electric motor makes the difference. At this point, the Seal 390 AWD leads by 0.36 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Seal 390 AWD is doing 155 km/h against 161 km/h for the 911 Carrera GTS (MT). The gap is 0.22 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 11.97 s. The 0.03 s gap represents roughly 2 m of track
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 911 Carrera GTS (MT) keeps accelerating towards 311 km/h. At 600 metres, the gap has dropped to 0.61 s.
Around 415 metres, both vehicles are level. This is the inversion point: the 911 Carrera GTS (MT) overcomes its launch deficit thanks to a 131 km/h higher top speed.
At 1,000 metres, the 911 Carrera GTS (MT) finishes in 21.25 s versus 23.93 s. The 2.68 s delta in favour of the 911 Carrera GTS (MT) shows that top speed makes a clear difference.
What the numbers don’t tell you
The Seal 390 AWD features all-wheel drive (AWD) against the 911 Carrera GTS (MT)’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 911 Carrera GTS (MT) at 311 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 0.36 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 911 Carrera GTS (MT) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
