Off the line, the Bmw 120d hits 100 km/h in 7.15 s versus 7.24 s for the Bmw i3 (120 Ah). Despite lacking instant torque, 190 hp of power compensates. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw i3 (120 Ah) is doing 122 km/h against 124 km/h for the Bmw 120d. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 120d crosses the line in 15.30 s versus 15.40 s. The 0.10 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the Bmw 120d continues to build its lead. At 600 metres, it runs at 172 km/h versus 150 km/h. At 1,000 metres, the Bmw 120d finishes in 27.53 s versus 29.80 s, with a 2.27 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 120d is capped at 228 km/h, the Bmw i3 (120 Ah) at 150 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 11.47 seconds. The 0.09 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.
