The start: 0 to 100 km/h

Off the line, the i3 hits 100 km/h in 7.24 s versus 9.77 s for the ë-C4 FWD. At this point, the i3 leads by 2.53 s and sits roughly 24 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i3 is doing 122 km/h against 110 km/h for the ë-C4 FWD. The gap is 1.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the i3 crosses the line in 15.40 s versus 17.29 s. The 1.88 s gap represents roughly 69 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The i3 maxes out at 150 km/h while the ë-C4 FWD keeps accelerating towards 204 km/h. At 600 metres, the gap is down to 2.14 s from 1.88 s at 400 metres.

At 1,000 metres, the i3 finishes in 29.80 s versus 31.39 s, with just 1.59 s to spare. The ë-C4 FWD fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the i3 and the ë-C4 FWD are governed to 150 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two electric powertrains, the difference comes down to power-to-weight ratio (7.47 kg/hp vs 11.25 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.91 seconds. The 2.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
