Off the line, the RS Q8 SUV hits 100 km/h in 3.87 s versus 5.86 s for the X4 xDrive30d. At this point, the RS Q8 SUV leads by 2.00 s and sits roughly 13 m ahead.
At 200 metres, the RS Q8 SUV is doing 156 km/h against 129 km/h for the X4 xDrive30d. The gap is 1.40 s. The challenger starts to claw back ground.
At 400 metres standing start, the RS Q8 SUV crosses the line in 11.88 s versus 14.18 s. The 2.30 s gap represents roughly 98 m of track - a gap visible to the naked eye.
Past 400 metres, the RS Q8 SUV continues to build its lead. At 600 metres, it runs at 217 km/h versus 177 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.56 s versus 26.04 s, with a 4.49 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 RS Q8 SUV is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X4 xDrive30d 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.86 kg/hp vs 6.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.38 seconds. The 2.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, RS Q8 SUV wins (3,87 s vs 5,86 s).
