Off the line, the S6 Avant e-tron hits 100 km/h in 4.03 s versus 7.75 s for the Bmw 420d Convertible. The instant torque of 855 Nm from the electric motor makes the difference. At this point, the S6 Avant e-tron leads by 3.72 s and sits roughly 18 m ahead.
At 200 metres, the S6 Avant e-tron is doing 150 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 2.11 s. The challenger starts to claw back ground.
At 400 metres standing start, the S6 Avant e-tron crosses the line in 12.29 s versus 15.64 s. The 3.35 s gap represents roughly 126 m of track - a gap visible to the naked eye.
Past 400 metres, the S6 Avant e-tron continues to build its lead. At 600 metres, it runs at 206 km/h versus 161 km/h. At 1,000 metres, the S6 Avant e-tron finishes in 22.44 s versus 28.69 s, with a 6.25 s lead. Both vehicles have similar top speeds (240 vs 236 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the S6 Avant e-tron is capped at 240 km/h, the Bmw 420d Convertible at 236 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
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 12.82 seconds. The 3.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S6 Avant e-tron wins (4,03 s vs 7,75 s).
