Off the line, the Bmw 420i hits 100 km/h in 7.44 s versus 7.75 s for the Bmw 420d Convertible. At this point, the Bmw 420i leads by 0.31 s and sits roughly 4 m ahead.
At 200 metres, the Bmw 420i is doing 117 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 0.16 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 15.64 s. The 0.26 s gap represents roughly 10 m of track - two to three car lengths.
Past 400 metres, the Bmw 420i continues to build its lead. At 600 metres, it runs at 163 km/h versus 161 km/h. At 1,000 metres, the Bmw 420i finishes in 28.23 s versus 28.69 s, with a 0.46 s lead. Both vehicles have similar top speeds (236 vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 420d Convertible is capped at 236 km/h, the Bmw 420i at 240 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 8.29 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 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i F32 wins (7,44 s vs 7,75 s).
420d Convertible G22 goes from 0 to 100 km/h in 7,75 seconds (calibrated simulation).
