Off the line, the Bmw X5 M50d hits 100 km/h in 5.15 s versus 6.74 s for the Bmw 525d. At this point, the Bmw X5 M50d leads by 1.59 s and sits roughly 14 m ahead.
At 200 metres, the Bmw X5 M50d is doing 136 km/h against 123 km/h for the Bmw 525d. The gap is 0.96 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X5 M50d crosses the line in 13.47 s versus 14.92 s. The 1.45 s gap represents roughly 60 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X5 M50d continues to build its lead. At 600 metres, it runs at 189 km/h versus 171 km/h. At 1,000 metres, the Bmw X5 M50d finishes in 24.60 s versus 27.19 s, with a 2.59 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 243 km/h), preventing any comeback.
The Bmw X5 M50d features all-wheel drive (AWD) against the Bmw 525d’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 X5 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 525d at 245 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 (5.69 kg/hp vs 7.32 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.75 seconds. The 1.59 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.
