Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 5.57 s for the Q8 SUV. At this point, the X4 M40d leads by 0.76 s and sits roughly 8 m ahead.
At 200 metres, the X4 M40d is doing 139 km/h against 131 km/h for the Q8 SUV. The gap is 0.50 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.13 s versus 13.90 s. The 0.77 s gap represents roughly 34 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 193 km/h versus 181 km/h. At 1,000 metres, the X4 M40d finishes in 24.04 s versus 25.53 s, with a 1.50 s lead. Both vehicles have similar top speeds (244 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the Q8 SUV and the X4 M40d 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 (6.18 kg/hp vs 5.94 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 0.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M40d G02 wins (4,81 s vs 5,57 s).
Q8 SUV goes from 0 to 100 km/h in 5,57 seconds (calibrated simulation).
Q8 SUV: 340 hp, ratio 6,18 kg/hp. X4 M40d G02: 340 hp, ratio 5,94 kg/hp.
Q8 SUV: 244 km/h. X4 M40d G02: 250 km/h.
