Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 5.29 s for the Bmw X6 M50d. At this point, the S5 Avant leads by 0.76 s and sits roughly 10 m ahead.
At 200 metres, the S5 Avant is doing 142 km/h against 135 km/h for the Bmw X6 M50d. The gap is 0.57 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 13.62 s. The 0.79 s gap represents roughly 36 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Avant continues to build its lead. At 600 metres, it runs at 197 km/h versus 187 km/h. At 1,000 metres, the S5 Avant finishes in 23.49 s versus 24.91 s, with a 1.43 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 X6 M50d and the S5 Avant 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 (5.73 kg/hp vs 5.35 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.26 seconds. The 0.76 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.
