The start: 0 to 100 km/h

Off the line, the Seal 313 2WD hits 100 km/h in 6.00 s versus 7.23 s for the Born. At this point, the Seal 313 2WD leads by 1.23 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Seal 313 2WD is doing 135 km/h against 122 km/h for the Born. The gap is 0.68 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 15.39 s. The 1.19 s gap represents roughly 48 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 160 km/h. At 1,000 metres, the Seal 313 2WD finishes in 26.31 s versus 28.98 s, with a 2.67 s lead.

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 Born at 160 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 8.51 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.41 seconds. The 1.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
