Off the line, the M440d xDrive hits 100 km/h in 4.57 s versus 7.17 s for the 520d. At this point, the M440d xDrive leads by 2.60 s and sits roughly 15 m ahead.
At 200 metres, the M440d xDrive is doing 140 km/h against 117 km/h for the 520d. The gap is 1.40 s. The challenger starts to claw back ground.
At 400 metres standing start, the M440d xDrive crosses the line in 12.89 s versus 15.20 s. The 2.30 s gap represents roughly 90 m of track - a gap visible to the naked eye.
Past 400 metres, the M440d xDrive continues to build its lead. At 600 metres, it runs at 196 km/h versus 163 km/h. At 1,000 metres, the M440d xDrive finishes in 23.61 s versus 28.10 s, with a 4.49 s lead.
The M440d xDrive features all-wheel drive (AWD) against the 520d’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the M440d xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 520d at 235 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 (5.38 kg/hp vs 8.82 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.01 seconds. The 2.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440d xDrive G22 wins (4,57 s vs 7,17 s).
M440d xDrive G22 goes from 0 to 100 km/h in 4,57 seconds (calibrated simulation).
