Bmw M440i xDrive vs Seal 313 2WD: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M440i xDrive hits 100 km/h in 4.47 s versus 6.00 s for the Seal 313 2WD. Despite lacking instant torque, 374 hp of power compensates. At this point, the Bmw M440i xDrive leads by 1.53 s and sits roughly 20 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M440i xDrive is doing 146 km/h against 135 km/h for the Seal 313 2WD. The gap is 1.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M440i xDrive crosses the line in 12.66 s versus 14.21 s. The 1.55 s gap represents roughly 69 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M440i xDrive continues to build its lead. At 600 metres, it runs at 204 km/h versus 180 km/h. At 1,000 metres, the Bmw M440i xDrive finishes in 22.96 s versus 26.31 s, with a 3.35 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M440i xDrive is capped at 250 km/h, the Seal 313 2WD 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 8.80 seconds. The 1.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M440i xDrive has a clear edge over the BYD Seal 313 2WD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
