Off the line, the X5 M50d hits 100 km/h in 5.15 s versus 5.45 s for the Z4 sDrive30i. At this point, the X5 M50d leads by 0.30 s and sits roughly 6 m ahead.
At 200 metres, the X5 M50d is doing 136 km/h against 136 km/h for the Z4 sDrive30i. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the X5 M50d crosses the line in 13.47 s versus 13.70 s. The 0.23 s gap represents roughly 11 m of track - two to three car lengths.
Past 400 metres, the X5 M50d continues to build its lead. At 600 metres, it runs at 189 km/h versus 189 km/h. At 1,000 metres, the X5 M50d finishes in 24.60 s versus 24.81 s, with a 0.21 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 Z4 sDrive30i 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 5.54 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.31 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X5 M50d F15 wins (5,15 s vs 5,45 s).
X5 M50d F15 goes from 0 to 100 km/h in 5,15 seconds (calibrated simulation).
