Off the line, the S6 Sportback e-tron hits 100 km/h in 4.08 s versus 6.48 s for the Bmw 125d. The instant torque of 855 Nm from the electric motor makes the difference. At this point, the S6 Sportback e-tron leads by 2.41 s and sits roughly 23 m ahead.
At 200 metres, the S6 Sportback e-tron is doing 146 km/h against 130 km/h for the Bmw 125d. The gap is 1.69 s. The challenger starts to claw back ground.
At 400 metres standing start, the S6 Sportback e-tron crosses the line in 12.52 s versus 14.67 s. The 2.15 s gap represents roughly 93 m of track - a gap visible to the naked eye.
Past 400 metres, the S6 Sportback e-tron continues to build its lead. At 600 metres, it runs at 191 km/h versus 180 km/h. At 1,000 metres, the S6 Sportback e-tron finishes in 23.58 s versus 26.39 s, with a 2.82 s lead. Both vehicles have similar top speeds (233 vs 240 km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the S6 Sportback e-tron and the Bmw 125d are governed to 240 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.81 seconds. The 2.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
