Off the line, the M135i xDrive hits 100 km/h in 4.78 s versus 5.15 s for the X5 M50d. At this point, the M135i xDrive leads by 0.37 s and sits roughly 1 m ahead.
At 200 metres, the M135i xDrive is doing 144 km/h against 136 km/h for the X5 M50d. The gap is 0.23 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 13.47 s. The 0.47 s gap represents roughly 22 m of track - two to three car lengths.
Past 400 metres, the M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 189 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 24.60 s, with a 1.01 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 M50d and the M135i xDrive 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 (5.69 kg/hp vs 4.98 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 0.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M135i xDrive F40 wins (4,78 s vs 5,15 s).
X5 M50d F15 goes from 0 to 100 km/h in 5,15 seconds (calibrated simulation).
