The start: 0 to 100 km/h

Off the line, the Seal 313 2WD hits 100 km/h in 6.00 s versus 6.31 s for the P7i. Despite the faster sprint time, the P7i 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 129 km/h for the P7i. The gap is 0.13 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 14.56 s. The 0.36 s gap represents roughly 16 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The Seal 313 2WD maxes out at 180 km/h while the P7i keeps accelerating towards 200 km/h. At 600 metres, the gap is down to 0.53 s from 0.36 s at 400 metres.

At 1,000 metres, the Seal 313 2WD finishes in 26.31 s versus 26.38 s, with just 0.06 s to spare. The P7i fails to fully close the launch gap.

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 P7i at 200 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 7.18 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.78 seconds. The 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
