The start: 0 to 100 km/h

Off the line, the 4 Long Range RWD hits 100 km/h in 6.73 s versus 7.44 s for the A3 allstreet. At this point, the 4 Long Range RWD leads by 0.71 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 4 Long Range RWD is doing 129 km/h against 120 km/h for the A3 allstreet. The gap is 0.36 s. The challenger starts to claw back ground.

At 400 metres standing start, the 4 Long Range RWD crosses the line in 14.92 s versus 15.61 s. The 0.69 s gap represents roughly 29 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 4 Long Range RWD continues to build its lead. At 600 metres, it runs at 176 km/h versus 168 km/h. At 1,000 metres, the 4 Long Range RWD finishes in 27.23 s versus 28.13 s, with a 0.90 s lead. Despite a higher top speed (230 km/h), the A3 allstreet never recovers its launch deficit.

What the numbers don’t tell you

Electronically capped at 180 km/h, the 4 Long Range RWD 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (7.00 kg/hp vs 7.89 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.95 seconds. The 0.71 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
