Off the line, the RS Q8 SUV hits 100 km/h in 3.87 s versus 4.87 s for the X4 M40i. At this point, the RS Q8 SUV leads by 1.00 s and sits roughly 10 m ahead.
At 200 metres, the RS Q8 SUV is doing 156 km/h against 142 km/h for the X4 M40i. The gap is 0.80 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 13.08 s. The 1.20 s gap represents roughly 58 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 198 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.56 s versus 23.70 s, with a 2.14 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the RS Q8 SUV and the X4 M40i are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.86 kg/hp vs 5.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.33 seconds. The 1.00 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 4,87 s).
