Off the line, the Bmw M550d xDrive hits 100 km/h in 4.66 s versus 4.84 s for the S4 TDI. At this point, the Bmw M550d xDrive leads by 0.17 s and sits roughly 1 m ahead.
At 200 metres, the Bmw M550d xDrive is doing 143 km/h against 140 km/h for the S4 TDI. The gap is 0.12 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M550d xDrive crosses the line in 12.91 s versus 13.12 s. The 0.20 s gap represents roughly 10 m of track - barely a car length.
Past 400 metres, the Bmw M550d xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 195 km/h. At 1,000 metres, the Bmw M550d xDrive finishes in 23.48 s versus 23.86 s, with a 0.38 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 Bmw M550d xDrive and the S4 TDI 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 (4.89 kg/hp vs 5.10 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.47 seconds. The 0.17 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
