The start: 0 to 100 km/h

Off the line, the S8 hits 100 km/h in 3.83 s versus 5.47 s for the S 350 d 4MATIC Saloon, long version. At this point, the S8 leads by 1.64 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S8 is doing 157 km/h against 131 km/h for the S 350 d 4MATIC Saloon, long version. The gap is 1.06 s. The challenger starts to claw back ground.

At 400 metres standing start, the S8 crosses the line in 11.81 s versus 13.68 s. The 1.88 s gap represents roughly 82 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S8 continues to build its lead. At 600 metres, it runs at 222 km/h versus 185 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 24.99 s, with a 3.73 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 S8 and the S 350 d 4MATIC Saloon, long version 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 (3.89 kg/hp vs 7.19 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.74 seconds. The 1.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
