The start: 0 to 100 km/h

Off the line, the Seal 390 AWD hits 100 km/h in 3.77 s versus 7.41 s for the Atto 3 Extended Range. At this point, the Seal 390 AWD leads by 3.64 s and sits roughly 25 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Seal 390 AWD is doing 155 km/h against 121 km/h for the Atto 3 Extended Range. The gap is 2.49 s. The challenger starts to claw back ground.

At 400 metres standing start, the Seal 390 AWD crosses the line in 11.93 s versus 15.57 s. The 3.63 s gap represents roughly 141 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Seal 390 AWD continues to build its lead. At 600 metres, it runs at 180 km/h versus 160 km/h. At 1,000 metres, the Seal 390 AWD finishes in 23.93 s versus 29.19 s, with a 5.26 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Seal 390 AWD is capped at 180 km/h, the Atto 3 Extended Range 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 (4.06 kg/hp vs 8.58 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.71 seconds. The 3.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
