Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 4.57 s for the M440d xDrive. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S5 Avant is doing 142 km/h against 140 km/h for the M440d xDrive. The gap is 0.02 s. The gap remains stable from the start.
At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 12.89 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.13 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals share the same electronic speed cap: the S5 Avant and the M440d 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 (5.35 kg/hp vs 5.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.21 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
