Off the line, the X5 M50d hits 100 km/h in 5.15 s versus 5.60 s for the Q8 SUV. Despite lacking instant torque, 400 hp of power compensates. At this point, the X5 M50d leads by 0.45 s and sits roughly 3 m ahead.
At 200 metres, the X5 M50d is doing 136 km/h against 131 km/h for the Q8 SUV. The gap is 0.26 s. The challenger starts to claw back ground.
At 400 metres standing start, the X5 M50d crosses the line in 13.47 s versus 13.94 s. The 0.47 s gap represents roughly 21 m of track - two to three car lengths.
Past 400 metres, the X5 M50d continues to build its lead. At 600 metres, it runs at 189 km/h versus 180 km/h. At 1,000 metres, the X5 M50d finishes in 24.60 s versus 25.66 s, with a 1.06 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X5 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Q8 SUV at 240 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.
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 8.93 seconds. The 0.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
