Off the line, the S 450 d 4MATIC Limousine Langversion hits 100 km/h in 5.13 s versus 5.15 s for the X5 M50d. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S 450 d 4MATIC Limousine Langversion is doing 135 km/h against 136 km/h for the X5 M50d. The gap is 0.14 s. The gap widens compared to the 0-100.
At 400 metres standing start, the S 450 d 4MATIC Limousine Langversion crosses the line in 13.33 s versus 13.47 s. The 0.14 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the S 450 d 4MATIC Limousine Langversion continues to build its lead. At 600 metres, it runs at 194 km/h versus 189 km/h. At 1,000 metres, the S 450 d 4MATIC Limousine Langversion finishes in 24.11 s versus 24.60 s, with a 0.49 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 S 450 d 4MATIC Limousine Langversion 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 6.14 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.07 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X5 M50d F15 and S 450 d 4MATIC Limousine Langversion W223 are neck and neck (5,13 s vs 5,15 s, no significant gap).
X5 M50d F15 goes from 0 to 100 km/h in 5,15 seconds (calibrated simulation).
