Off the line, the M340i xDrive hits 100 km/h in 4.46 s versus 4.53 s for the S5 Avant. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the M340i xDrive is doing 147 km/h against 142 km/h for the S5 Avant. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the M340i xDrive crosses the line in 12.56 s versus 12.83 s. The 0.27 s gap represents roughly 13 m of track - two to three car lengths.
Past 400 metres, the M340i xDrive continues to build its lead. At 600 metres, it runs at 207 km/h versus 197 km/h. At 1,000 metres, the M340i xDrive finishes in 22.70 s versus 23.49 s, with a 0.79 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 M340i xDrive 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 (4.47 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 7.09 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M340i xDrive G20 and S5 Avant are neck and neck (4,46 s vs 4,53 s, no significant gap).
M340i xDrive G20 goes from 0 to 100 km/h in 4,46 seconds (calibrated simulation).
