The start: 0 to 100 km/h

Off the line, the P7i hits 100 km/h in 6.31 s versus 9.33 s for the Seal U 160kW 2WD. At this point, the P7i leads by 3.02 s and sits roughly 33 m ahead.

From 100 km/h to 400 metres

At 200 metres, the P7i is doing 129 km/h against 115 km/h for the Seal U 160kW 2WD. The gap is 1.91 s. The challenger starts to claw back ground.

At 400 metres standing start, the P7i crosses the line in 14.56 s versus 17.01 s. The 2.44 s gap represents roughly 94 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the P7i continues to build its lead. At 600 metres, it runs at 178 km/h versus 160 km/h. At 1,000 metres, the P7i finishes in 26.38 s versus 30.73 s, with a 4.36 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the Seal U 160kW 2WD 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 (7.18 kg/hp vs 9.15 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.04 seconds. The 3.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
