The start: 0 to 100 km/h

Off the line, the S6 Sportback e-tron hits 100 km/h in 4.08 s versus 8.51 s for the G9. At this point, the S6 Sportback e-tron leads by 4.44 s and sits roughly 32 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S6 Sportback e-tron is doing 146 km/h against 120 km/h for the G9. The gap is 2.95 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 16.32 s. The 3.80 s gap represents roughly 148 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S6 Sportback e-tron continues to build its lead. At 600 metres, it runs at 191 km/h versus 169 km/h. At 1,000 metres, the S6 Sportback e-tron finishes in 23.58 s versus 28.71 s, with a 5.13 s lead.

What the numbers don’t tell you

The S6 Sportback e-tron features all-wheel drive (AWD) against the G9’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the S6 Sportback e-tron is capped at 240 km/h, the G9 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 7.18 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.63 seconds. The 4.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
