Seal 313 2WD vs P7: chronicle of a drag race at 180 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 6.58 s for the P7. At this point, the Seal 313 2WD leads by 0.58 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Seal 313 2WD is doing 135 km/h against 127 km/h for the P7. The gap is 0.31 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 14.81 s. The 0.61 s gap represents roughly 26 m of track — two to three car lengths.
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 170 km/h. At 1,000 metres, the Seal 313 2WD finishes in 26.31 s versus 27.64 s, with a 1.33 s lead. Both vehicles have similar top speeds (180 vs 170 km/h), preventing any comeback.
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 P7 at 170 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (6.35 kg/hp vs 7.59 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.18 seconds. The 0.58 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 Xpeng P7 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
