Audi RS e-tron GT vs Audi RS6 Performance Avant: which is truly faster?

Off the line, the RS e-tron GT hits 100 km/h in 3.33 s versus 3.46 s for the RS6 Performance Avant. The instant torque of 830 Nm from the electric motor makes the difference. At this point, the RS e-tron GT leads by 0.13 s and sits roughly 2 m ahead.

At 200 metres, the RS e-tron GT is doing 163 km/h against 165 km/h for the RS6 Performance Avant. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the RS6 Performance Avant crosses the line in 11.30 s versus 11.31 s. The 0.01 s gap represents roughly 0 m of track

Past 400 metres, the RS6 Performance Avant continues to build its lead. At 600 metres, it runs at 231 km/h versus 227 km/h. At 1,000 metres, the RS6 Performance Avant finishes in 20.37 s versus 20.60 s, with a 0.23 s lead.

Electronically capped at 250 (i.e. 155 mph — industry threshold) km/h, the RS e-tron GT never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

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 5.02 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
