Off the line, the Bmw M340d xDrive hits 100 km/h in 4.58 s versus 4.84 s for the S4 TDI. At this point, the Bmw M340d xDrive leads by 0.26 s and sits roughly 6 m ahead.
At 200 metres, the Bmw M340d xDrive is doing 141 km/h against 140 km/h for the S4 TDI. The gap is 0.23 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M340d xDrive crosses the line in 12.87 s versus 13.12 s. The 0.25 s gap represents roughly 12 m of track — two to three car lengths.
Past 400 metres, the Bmw M340d xDrive continues to build its lead. At 600 metres, it runs at 197 km/h versus 195 km/h. At 1,000 metres, the Bmw M340d xDrive finishes in 23.53 s versus 23.86 s, with a 0.32 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 S4 TDI and the Bmw M340d 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 (5.10 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 7.47 seconds. The 0.26 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.
