Off the line, the Bmw i4 M50 xDrive hits 100 km/h in 3.92 s versus 7.56 s for the Bmw 520d. The instant torque of 795 Nm from the electric motor makes the difference. At this point, the Bmw i4 M50 xDrive leads by 3.64 s and sits roughly 12 m ahead.
At 200 metres, the Bmw i4 M50 xDrive is doing 155 km/h against 115 km/h for the Bmw 520d. The gap is 2.02 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 15.48 s. The 3.47 s gap represents roughly 129 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 159 km/h. At 1,000 metres, the Bmw i4 M50 xDrive finishes in 21.97 s versus 28.71 s, with a 6.74 s lead. Both vehicles have similar top speeds (225 vs 225 km/h), preventing any comeback.
The Bmw i4 M50 xDrive features all-wheel drive (AWD) against the Bmw 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 share the same electronic speed cap: the Bmw i4 M50 xDrive and the Bmw 520d are governed to 225 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 3.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i4 M50 xDrive G26 wins (3,92 s vs 7,56 s).
