The start: 0 to 100 km/h

Off the line, the A5 Avant hits 100 km/h in 7.72 s versus 7.79 s for the A4 40 TDI. The 0.07 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the A5 Avant is doing 122 km/h against 122 km/h for the A4 40 TDI. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the A5 Avant crosses the line in 15.70 s versus 15.77 s. The 0.06 s gap represents roughly 3 m of track — barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory — both rivals run in formation to the line. The 0.14 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere — range, comfort, charging network reliability.

What the numbers don’t tell you

Electronically capped at 245 km/h, the A5 Avant 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 combustion powertrains, the difference comes down to power-to-weight ratio (8.38 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.76 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
