Off the line, the S8 hits 100 km/h in 3.83 s versus 4.46 s for the Bmw M340i xDrive. At this point, the S8 leads by 0.63 s and sits roughly 5 m ahead.
At 200 metres, the S8 is doing 157 km/h against 147 km/h for the Bmw M340i xDrive. The gap is 0.47 s. The challenger starts to claw back ground.
At 400 metres standing start, the S8 crosses the line in 11.81 s versus 12.56 s. The 0.75 s gap represents roughly 38 m of track - a gap visible to the naked eye.
Past 400 metres, the S8 continues to build its lead. At 600 metres, it runs at 222 km/h versus 207 km/h. At 1,000 metres, the S8 finishes in 21.26 s versus 22.70 s, with a 1.44 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 S8 and the Bmw M340i 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 (3.89 kg/hp vs 4.47 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.65 seconds. The 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S8 wins (3,83 s vs 4,46 s).
