Off the line, the Bmw 420d Convertible hits 100 km/h in 7.75 s versus 8.35 s for the Bmw 118d. At this point, the Bmw 420d Convertible leads by 0.60 s and sits roughly 14 m ahead.
At 200 metres, the Bmw 420d Convertible is doing 116 km/h against 115 km/h for the Bmw 118d. The gap is 0.53 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 420d Convertible crosses the line in 15.64 s versus 16.20 s. The 0.56 s gap represents roughly 22 m of track - two to three car lengths.
Past 400 metres, the Bmw 420d Convertible continues to build its lead. At 600 metres, it runs at 161 km/h versus 159 km/h. At 1,000 metres, the Bmw 420d Convertible finishes in 28.69 s versus 29.44 s, with a 0.75 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 420d Convertible is capped at 236 km/h, the Bmw 118d at 218 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 (9.34 kg/hp vs 9.33 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.49 seconds. The 0.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420d Convertible G22 wins (7,75 s vs 8,35 s).
420d Convertible G22 goes from 0 to 100 km/h in 7,75 seconds (calibrated simulation).
