Off the line, the Bmw i4 M50 xDrive hits 100 km/h in 3.92 s versus 8.07 s for the Bmw 520e. At this point, the Bmw i4 M50 xDrive leads by 4.15 s and sits roughly 15 m ahead.
At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 113 km/h for the Bmw 520e. The gap is 2.28 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw i4 M50 xDrive crosses the line in 12.01 s versus 15.86 s. The 3.86 s gap represents roughly 140 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 154 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 29.49 s, with a 7.52 s lead. Both vehicles have similar top speeds (225 vs 213 km/h), preventing any comeback.
The Bmw i4 M50 xDrive features all-wheel drive (AWD) against the Bmw 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 Bmw i4 M50 xDrive is capped at 225 km/h, the Bmw 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 (4.07 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 4.15 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.
