Off the line, the Bmw 420d Convertible hits 100 km/h in 7.75 s versus 8.14 s for the Bmw 220d Gran Tourer. At this point, the Bmw 420d Convertible leads by 0.39 s and sits roughly 18 m ahead.
At 200 metres, the Bmw 420d Convertible is doing 116 km/h against 118 km/h for the Bmw 220d Gran Tourer. The gap is 0.59 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 420d Convertible crosses the line in 15.64 s versus 16.10 s. The 0.45 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The Bmw 220d Gran Tourer maxes out at 220 km/h while the Bmw 420d Convertible keeps accelerating towards 236 km/h. At 600 metres, the gap is down to 0.37 s from 0.45 s at 400 metres.
At 1,000 metres, the Bmw 420d Convertible finishes in 28.69 s versus 28.97 s, with just 0.28 s to spare. The Bmw 220d Gran Tourer fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the Bmw 220d Gran Tourer is capped at 220 km/h, the Bmw 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 (8.18 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 0.39 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 8,14 s).
220d Gran Tourer F22 goes from 0 to 100 km/h in 8,14 seconds (calibrated simulation).
