Off the line, the Bmw i3s (120 Ah) hits 100 km/h in 6.81 s versus 7.46 s for the Bmw 320e. Despite the faster sprint time, the Bmw 320e is 7 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 320e is doing 115 km/h against 124 km/h for the Bmw i3s (120 Ah). The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i3s (120 Ah) crosses the line in 15.05 s versus 15.43 s. The 0.39 s gap represents roughly 15 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The Bmw i3s (120 Ah) maxes out at 160 km/h while the Bmw 320e keeps accelerating towards 215 km/h. At 600 metres, the gap is down to 0.64 s from 0.39 s at 400 metres.
At 1,000 metres, the Bmw i3s (120 Ah) finishes in 28.59 s versus 28.77 s, with just 0.18 s to spare. The Bmw 320e fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Bmw 320e is capped at 220 km/h, the Bmw i3s (120 Ah) 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (8.65 kg/hp vs 7.01 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.74 seconds. The 0.65 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
