The start: 0 to 100 km/h

Off the line, the S8 hits 100 km/h in 3.83 s versus 4.18 s for the M3. At this point, the S8 leads by 0.35 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S8 is doing 157 km/h against 154 km/h for the M3. The gap is 0.34 s. The gap remains stable from the start.

At 400 metres standing start, the S8 crosses the line in 11.81 s versus 12.25 s. The 0.44 s gap represents roughly 24 m of track - two to three car lengths.

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 216 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 21.95 s, with a 0.68 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 M3 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 3.55 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.22 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
