Off the line, the Bmw i3 (120 Ah) hits 100 km/h in 7.24 s versus 8.65 s for the Bmw 218i Coupé. The instant torque of 250 Nm from the electric motor makes the difference. At this point, the Bmw i3 (120 Ah) leads by 1.41 s and sits roughly 4 m ahead.
At 200 metres, the Bmw i3 (120 Ah) is doing 122 km/h against 112 km/h for the Bmw 218i Coupé. The gap is 0.43 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i3 (120 Ah) crosses the line in 15.40 s versus 16.29 s. The 0.89 s gap represents roughly 34 m of track — a gap visible to the naked eye.
Past 400 metres, the gap narrows. The Bmw i3 (120 Ah) maxes out at 150 km/h while the Bmw 218i Coupé keeps accelerating towards 222 km/h. At 600 metres, the gap is down to 0.98 s from 0.89 s at 400 metres.
At 1,000 metres, the Bmw i3 (120 Ah) finishes in 29.80 s versus 29.82 s, with just 0.02 s to spare. The Bmw 218i Coupé fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Bmw i3 (120 Ah) is capped at 150 km/h, the Bmw 218i Coupé at 224 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.27 seconds. The 1.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
