Off the line, the 545e xDrive hits 100 km/h in 4.68 s versus 8.07 s for the 520e. At this point, the 545e xDrive leads by 3.40 s and sits roughly 16 m ahead.
At 200 metres, the 545e xDrive is doing 143 km/h against 113 km/h for the 520e. The gap is 1.72 s. The challenger starts to claw back ground.
At 400 metres standing start, the 545e xDrive crosses the line in 12.91 s versus 15.86 s. The 2.95 s gap represents roughly 109 m of track - a gap visible to the naked eye.
Past 400 metres, the 545e xDrive continues to build its lead. At 600 metres, it runs at 200 km/h versus 154 km/h. At 1,000 metres, the 545e xDrive finishes in 23.40 s versus 29.49 s, with a 6.09 s lead.
The 545e xDrive features all-wheel drive (AWD) against the 520e’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 545e xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 520e at 218 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (4.94 kg/hp vs 9.31 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.80 seconds. The 3.40 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
