Off the line, the Bmw 120i hits 100 km/h in 7.12 s versus 9.34 s for the Bmw 218i Convertible. At this point, the Bmw 120i leads by 2.22 s and sits roughly 15 m ahead.
At 200 metres, the Bmw 120i is doing 122 km/h against 110 km/h for the Bmw 218i Convertible. The gap is 0.98 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 120i crosses the line in 15.22 s versus 16.78 s. The 1.56 s gap represents roughly 58 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 120i continues to build its lead. At 600 metres, it runs at 170 km/h versus 154 km/h. At 1,000 metres, the Bmw 120i finishes in 27.52 s versus 30.47 s, with a 2.94 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 120i is capped at 225 km/h, the Bmw 218i Convertible at 207 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 combustion powertrains, the difference comes down to power-to-weight ratio (7.47 kg/hp vs 11.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.16 seconds. The 2.22 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.
