The start: 0 to 100 km/h

Off the line, the Seal 313 2WD hits 100 km/h in 6.00 s versus 7.75 s for the 520e. Despite the faster sprint time, the 520e is 1 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 114 km/h for the 520e. The gap is 0.57 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 15.64 s. The 1.44 s gap represents roughly 55 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 157 km/h. At 1,000 metres, the Seal 313 2WD finishes in 26.31 s versus 29.03 s, with a 2.72 s lead. Despite a higher top speed (220 km/h), the 520e 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 520e at 225 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (6.35 kg/hp vs 9.00 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.17 seconds. The 1.75 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
