Seal 390 AWD vs 911 Carrera GTS Cabriolet: chronicle of a drag race at 309 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera GTS Cabriolet hits 100 km/h in 3.70 s versus 3.77 s for the Seal 390 AWD. Despite lacking instant torque, 480 hp of power compensates. The 0.07 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera GTS Cabriolet is doing 164 km/h against 155 km/h for the Seal 390 AWD. The gap is 0.14 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 911 Carrera GTS Cabriolet crosses the line in 11.52 s versus 11.93 s. The 0.41 s gap represents roughly 21 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera GTS Cabriolet continues to build its lead. At 600 metres, it runs at 227 km/h versus 180 km/h. At 1,000 metres, the 911 Carrera GTS Cabriolet finishes in 20.74 s versus 23.93 s, with a 3.19 s lead.
What the numbers don’t tell you
The Seal 390 AWD features all-wheel drive (AWD) against the 911 Carrera GTS Cabriolet’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 Cabriolet at 309 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 5.59 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Seal 390 AWD and Porsche 911 Carrera GTS Cabriolet are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
