The start: 0 to 100 km/h

Off the line, the S 500 4MATIC Saloon, long version hits 100 km/h in 4.45 s versus 4.84 s for the S4 TDI. At this point, the S 500 4MATIC Saloon, long version leads by 0.38 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S 500 4MATIC Saloon, long version is doing 145 km/h against 140 km/h for the S4 TDI. The gap is 0.35 s. The gap remains stable from the start.

At 400 metres standing start, the S 500 4MATIC Saloon, long version crosses the line in 12.59 s versus 13.12 s. The 0.53 s gap represents roughly 26 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S 500 4MATIC Saloon, long version continues to build its lead. At 600 metres, it runs at 207 km/h versus 195 km/h. At 1,000 metres, the S 500 4MATIC Saloon, long version finishes in 22.69 s versus 23.86 s, with a 1.17 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.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the S 500 4MATIC Saloon, long version and the S4 TDI 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 (4.89 kg/hp vs 5.10 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.47 seconds. The 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
