Off the line, the X5 M Competition hits 100 km/h in 3.83 s versus 3.87 s for the RS Q8 SUV. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the RS Q8 SUV is doing 156 km/h against 155 km/h for the X5 M Competition. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the RS Q8 SUV crosses the line in 11.88 s versus 11.94 s. The 0.07 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the RS Q8 SUV continues to build its lead. At 600 metres, it runs at 217 km/h versus 215 km/h. At 1,000 metres, the RS Q8 SUV finishes in 21.56 s versus 21.80 s, with a 0.24 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 X5 M Competition and the RS Q8 SUV 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 (3.74 kg/hp vs 3.86 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.72 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
