Off the line, the Bmw M440i xDrive hits 100 km/h in 4.47 s versus 7.75 s for the Bmw 420d Convertible. At this point, the Bmw M440i xDrive leads by 3.28 s and sits roughly 18 m ahead.
At 200 metres, the Bmw M440i xDrive is doing 146 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 1.82 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M440i xDrive crosses the line in 12.66 s versus 15.64 s. The 2.98 s gap represents roughly 113 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M440i xDrive continues to build its lead. At 600 metres, it runs at 204 km/h versus 161 km/h. At 1,000 metres, the Bmw M440i xDrive finishes in 22.96 s versus 28.69 s, with a 5.73 s lead. Both vehicles have similar top speeds (250 (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 Bmw M440i xDrive is capped at 250 (i.e. 155 mph — industry threshold) 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 (4.65 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 3.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
