Off the line, the S4 TDI hits 100 km/h in 4.84 s versus 4.96 s for the 540i xDrive. At this point, the S4 TDI leads by 0.13 s and sits roughly 3 m ahead.
At 200 metres, the S4 TDI is doing 140 km/h against 141 km/h for the 540i xDrive. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the S4 TDI crosses the line in 13.12 s versus 13.16 s. The 0.04 s gap represents roughly 2 m of track
Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.
At 1,000 metres, the 540i xDrive finishes in 23.73 s versus 23.86 s. The 0.13 s delta shows an extremely tight race.
Both rivals share the same electronic speed cap: the S4 TDI and the 540i 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 5.24 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.48 seconds. The 0.13 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.
