Off the line, the X4 M40d hits 100 km/h in 4.94 s versus 5.97 s for the Q8 SUV. At this point, the X4 M40d leads by 1.03 s and sits roughly 4 m ahead.
At 200 metres, the X4 M40d is doing 137 km/h against 125 km/h for the Q8 SUV. The gap is 0.52 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.29 s versus 14.25 s. The 0.96 s gap represents roughly 41 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 190 km/h versus 174 km/h. At 1,000 metres, the X4 M40d finishes in 24.38 s versus 26.36 s, with a 1.98 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 241 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X4 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Q8 SUV at 241 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 (5.81 kg/hp vs 7.55 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.86 seconds. The 1.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
