Off the line, the S5 Sedan hits 100 km/h in 4.50 s versus 4.54 s for the Bmw M140i. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S5 Sedan is doing 142 km/h against 151 km/h for the Bmw M140i. The gap is 0.06 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 12.80 s. The 0.20 s gap represents roughly 10 m of track - barely a car length.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 198 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 23.38 s, with a 0.73 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 S5 Sedan and the Bmw M140i 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 (5.31 kg/hp vs 4.32 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.04 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.
