Off the line, the 740d xDrive hits 100 km/h in 5.16 s versus 7.84 s for the 520i. At this point, the 740d xDrive leads by 2.68 s and sits roughly 15 m ahead.
At 200 metres, the 740d xDrive is doing 136 km/h against 114 km/h for the 520i. The gap is 1.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the 740d xDrive crosses the line in 13.47 s versus 15.68 s. The 2.21 s gap represents roughly 84 m of track - a gap visible to the naked eye.
Past 400 metres, the 740d xDrive continues to build its lead. At 600 metres, it runs at 190 km/h versus 159 km/h. At 1,000 metres, the 740d xDrive finishes in 24.53 s versus 28.87 s, with a 4.34 s lead.
The 740d xDrive features all-wheel drive (AWD) against the 520i’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 740d xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 520i 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 (5.84 kg/hp vs 8.75 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.04 seconds. The 2.68 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 740d xDrive G11 wins (5,16 s vs 7,84 s).
740d xDrive G11 goes from 0 to 100 km/h in 5,16 seconds (calibrated simulation).
