Off the line, the X5 xDrive40i hits 100 km/h in 5.65 s versus 6.93 s for the Q8 SUV. At this point, the X5 xDrive40i leads by 1.28 s and sits roughly 7 m ahead.
At 200 metres, the X5 xDrive40i is doing 131 km/h against 119 km/h for the Q8 SUV. The gap is 0.61 s. The challenger starts to claw back ground.
At 400 metres standing start, the X5 xDrive40i crosses the line in 13.93 s versus 15.03 s. The 1.11 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the X5 xDrive40i continues to build its lead. At 600 metres, it runs at 181 km/h versus 165 km/h. At 1,000 metres, the X5 xDrive40i finishes in 25.54 s versus 27.77 s, with a 2.23 s lead.
Both rivals are electronically governed, but not at the same level: the X5 xDrive40i is capped at 243 km/h, the Q8 SUV at 226 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 (6.31 kg/hp vs 9.35 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.52 seconds. The 1.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X5 xDrive40i G05 wins (5,65 s vs 6,93 s).
X5 xDrive40i G05 goes from 0 to 100 km/h in 5,65 seconds (calibrated simulation).
