Off the line, the Bmw M440i xDrive hits 100 km/h in 4.47 s versus 9.32 s for the Bmw 318d Steptronic. At this point, the Bmw M440i xDrive leads by 4.85 s and sits roughly 31 m ahead.
At 200 metres, the Bmw M440i xDrive is doing 146 km/h against 111 km/h for the Bmw 318d Steptronic. The gap is 2.87 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 16.91 s. The 4.25 s gap represents roughly 152 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 153 km/h. At 1,000 metres, the Bmw M440i xDrive finishes in 22.96 s versus 30.62 s, with a 7.66 s lead.
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 318d Steptronic at 212 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 9.66 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.08 seconds. The 4.85 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i xDrive F32 wins (4,47 s vs 9,32 s).
M440i xDrive F32 goes from 0 to 100 km/h in 4,47 seconds (calibrated simulation).
