Off the line, the 230i Convertible hits 100 km/h in 5.84 s versus 7.75 s for the 420d Convertible. At this point, the 230i Convertible leads by 1.91 s and sits roughly 14 m ahead.
At 200 metres, the 230i Convertible is doing 129 km/h against 116 km/h for the 420d Convertible. The gap is 0.97 s. The challenger starts to claw back ground.
At 400 metres standing start, the 230i Convertible crosses the line in 14.08 s versus 15.64 s. The 1.56 s gap represents roughly 61 m of track - a gap visible to the naked eye.
Past 400 metres, the 230i Convertible continues to build its lead. At 600 metres, it runs at 179 km/h versus 161 km/h. At 1,000 metres, the 230i Convertible finishes in 25.81 s versus 28.69 s, with a 2.88 s lead. Both vehicles have similar top speeds (249 (i.e. 155 mph - industry threshold) vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 230i Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 420d Convertible at 236 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 (6.39 kg/hp vs 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 1.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 230i Convertible F44 wins (5,84 s vs 7,75 s).
230i Convertible F44 goes from 0 to 100 km/h in 5,84 seconds (calibrated simulation).
