Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 5.49 s for the X7 M50d. At this point, the X4 M40d leads by 0.68 s and sits roughly 8 m ahead.
At 200 metres, the X4 M40d is doing 139 km/h against 132 km/h for the X7 M50d. The gap is 0.47 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.13 s versus 13.82 s. The 0.69 s gap represents roughly 31 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 184 km/h. At 1,000 metres, the X4 M40d finishes in 24.04 s versus 25.28 s, with a 1.24 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 X7 M50d 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 (6.15 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 8.69 seconds. The 0.68 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 5,49 s).
X7 M50d G07 goes from 0 to 100 km/h in 5,49 seconds (calibrated simulation).
X7 M50d G07: 400 hp, ratio 6,15 kg/hp. X4 M40d G02: 340 hp, ratio 5,94 kg/hp.
X7 M50d G07: 250 km/h. X4 M40d G02: 250 km/h.
