Off the line, the Bmw 125d hits 100 km/h in 6.48 s versus 9.34 s for the Bmw 218i Convertible. At this point, the Bmw 125d leads by 2.86 s and sits roughly 15 m ahead.
At 200 metres, the Bmw 125d is doing 130 km/h against 110 km/h for the Bmw 218i Convertible. The gap is 1.24 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 125d crosses the line in 14.67 s versus 16.78 s. The 2.11 s gap represents roughly 77 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw 125d continues to build its lead. At 600 metres, it runs at 180 km/h versus 154 km/h. At 1,000 metres, the Bmw 125d finishes in 26.39 s versus 30.47 s, with a 4.07 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 125d is capped at 240 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 (6.61 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 2.86 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.
