911 Turbo S vs Seal 390 AWD: chronicle of a drag race at 317 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Turbo S hits 100 km/h in 2.95 s versus 3.77 s for the Seal 390 AWD. Despite lacking instant torque, 568 hp of power compensates. At this point, the 911 Turbo S leads by 0.82 s and sits roughly 8 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Turbo S is doing 176 km/h against 155 km/h for the Seal 390 AWD. The gap is 0.82 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Turbo S crosses the line in 10.57 s versus 11.93 s. The 1.36 s gap represents roughly 68 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Turbo S continues to build its lead. At 600 metres, it runs at 243 km/h versus 180 km/h. At 1,000 metres, the 911 Turbo S finishes in 19.22 s versus 23.93 s, with a 4.71 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Turbo S is capped at 317 km/h, the Seal 390 AWD at 180 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 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Turbo S has a clear edge over the BYD Seal 390 AWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
