Off the line, the Bmw M140i hits 100 km/h in 4.54 s versus 9.57 s for the Bmw 218i Convertible. At this point, the Bmw M140i leads by 5.03 s and sits roughly 24 m ahead.
At 200 metres, the Bmw M140i is doing 151 km/h against 109 km/h for the Bmw 218i Convertible. The gap is 2.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 17.01 s. The 4.41 s gap represents roughly 154 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 150 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 30.99 s, with a 8.34 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw M140i is capped at 250 (i.e. 155 mph - industry threshold) 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 (4.32 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 15.88 seconds. The 5.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M140i F20LCI wins (4,54 s vs 9,57 s).
M140i F20LCI goes from 0 to 100 km/h in 4,54 seconds (calibrated simulation).
