Off the line, the S6 Avant e-tron hits 100 km/h in 4.03 s versus 5.33 s for the Bmw X7 xDrive50i. The instant torque of 855 Nm from the electric motor makes the difference. At this point, the S6 Avant e-tron leads by 1.30 s and sits roughly 11 m ahead.
At 200 metres, the S6 Avant e-tron is doing 150 km/h against 137 km/h for the Bmw X7 xDrive50i. The gap is 0.91 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 13.57 s. The 1.28 s gap represents roughly 59 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 190 km/h. At 1,000 metres, the S6 Avant e-tron finishes in 22.44 s versus 24.64 s, with a 2.20 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) 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 X7 xDrive50i at 250 (i.e. 155 mph - industry threshold) 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 8.16 seconds. The 1.30 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 5,33 s).
