Seal 313 2WD vs Cayenne Diesel: chronicle of a drag race at 217 km/h
The launch: 0 to 100 km/h
Off the line, the Seal 313 2WD hits 100 km/h in 6.00 s versus 7.11 s for the Cayenne Diesel. The instant torque of 360 Nm from the electric motor makes the difference. Despite the faster sprint time, the Cayenne Diesel is 3 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
From 100 km/h to 400 metres
At 200 metres, the Seal 313 2WD is doing 135 km/h against 118 km/h for the Cayenne Diesel. The gap is 0.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the Seal 313 2WD crosses the line in 14.21 s versus 15.22 s. The 1.02 s gap represents roughly 41 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Seal 313 2WD continues to build its lead. At 600 metres, it runs at 180 km/h versus 163 km/h. At 1,000 metres, the Seal 313 2WD finishes in 26.31 s versus 28.17 s, with a 1.86 s lead. Despite a higher top speed (217 km/h), the Cayenne Diesel never recovers its launch deficit.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Seal 313 2WD is capped at 180 km/h, the Cayenne Diesel at 217 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 11.83 seconds. The 1.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
BYD Seal 313 2WD has a clear edge over the Porsche Cayenne Diesel to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
