The start: 0 to 100 km/h

Off the line, the A3 allstreet hits 100 km/h in 7.44 s versus 7.46 s for the 320e. The 0.02 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 320e is doing 115 km/h against 120 km/h for the A3 allstreet. The gap is 0.43 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 320e crosses the line in 15.43 s versus 15.61 s. The 0.17 s gap represents roughly 7 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The 320e maxes out at 215 km/h while the A3 allstreet keeps accelerating towards 230 km/h. At 600 metres, the gap has dropped to 0.10 s.

Around 527 metres, both vehicles are level. This is the inversion point: the A3 allstreet overcomes its launch deficit thanks to a 15 km/h higher top speed.

At 1,000 metres, the A3 allstreet finishes in 28.13 s versus 28.77 s. The 0.63 s delta in favour of the A3 allstreet shows that top speed makes a clear difference.

What the numbers don’t tell you

Electronically capped at 220 km/h, the 320e 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 (7.89 kg/hp vs 8.65 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.74 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
