Off the line, the S5 Sedan hits 100 km/h in 4.50 s versus 5.24 s for the 740Ld xDrive. At this point, the S5 Sedan leads by 0.74 s and sits roughly 8 m ahead.
At 200 metres, the S5 Sedan is doing 142 km/h against 136 km/h for the 740Ld xDrive. The gap is 0.52 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Sedan crosses the line in 12.80 s versus 13.54 s. The 0.74 s gap represents roughly 34 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Sedan continues to build its lead. At 600 metres, it runs at 198 km/h versus 190 km/h. At 1,000 metres, the S5 Sedan finishes in 23.38 s versus 24.60 s, with a 1.22 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 740Ld 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 (5.31 kg/hp vs 5.98 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.19 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Sedan wins (4,50 s vs 5,24 s).
S5 Sedan goes from 0 to 100 km/h in 4,50 seconds (calibrated simulation).
