Off the line, the S6 Sportback e-tron hits 100 km/h in 4.08 s versus 6.04 s for the iX xDrive40. At this point, the S6 Sportback e-tron leads by 1.96 s and sits roughly 13 m ahead.
At 200 metres, the S6 Sportback e-tron is doing 146 km/h against 127 km/h for the iX xDrive40. The gap is 1.25 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 14.36 s. The 1.84 s gap represents roughly 78 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 175 km/h. At 1,000 metres, the S6 Sportback e-tron finishes in 23.58 s versus 26.37 s, with a 2.79 s lead.
Both rivals are electronically governed, but not at the same level: the S6 Sportback e-tron is capped at 240 km/h, the iX xDrive40 at 200 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (4.28 kg/hp vs 7.48 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.74 seconds. The 1.96 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S6 Sportback e-tron wins (4,08 s vs 6,04 s).
S6 Sportback e-tron goes from 0 to 100 km/h in 4,08 seconds (calibrated simulation).
