Off the line, the X5 M50i hits 100 km/h in 4.34 s versus 5.57 s for the Q8 SUV. At this point, the X5 M50i leads by 1.23 s and sits roughly 7 m ahead.
At 200 metres, the X5 M50i is doing 150 km/h against 131 km/h for the Q8 SUV. The gap is 0.83 s. The challenger starts to claw back ground.
At 400 metres standing start, the X5 M50i crosses the line in 12.43 s versus 13.90 s. The 1.47 s gap represents roughly 65 m of track - a gap visible to the naked eye.
Past 400 metres, the X5 M50i continues to build its lead. At 600 metres, it runs at 209 km/h versus 181 km/h. At 1,000 metres, the X5 M50i finishes in 22.50 s versus 25.53 s, with a 3.03 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 244 km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the X5 M50i and the 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 (4.25 kg/hp vs 6.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.84 seconds. The 1.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X5 M50i G05 wins (4,34 s vs 5,57 s).
X5 M50i G05 goes from 0 to 100 km/h in 4,34 seconds (calibrated simulation).
