The start: 0 to 100 km/h

Off the line, the i4 eDrive35 hits 100 km/h in 6.08 s versus 9.90 s for the A3 Sportback. The instant torque of 400 Nm from the electric motor makes the difference. At this point, the i4 eDrive35 leads by 3.82 s and sits roughly 23 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i4 eDrive35 is doing 131 km/h against 108 km/h for the A3 Sportback. The gap is 1.81 s. The challenger starts to claw back ground.

At 400 metres standing start, the i4 eDrive35 crosses the line in 14.38 s versus 17.23 s. The 2.85 s gap represents roughly 101 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i4 eDrive35 continues to build its lead. At 600 metres, it runs at 179 km/h versus 149 km/h. At 1,000 metres, the i4 eDrive35 finishes in 26.26 s versus 31.33 s, with a 5.08 s lead. Despite a higher top speed (209 km/h), the A3 Sportback never recovers its launch deficit.

What the numbers don’t tell you

Electronically capped at 190 km/h, the i4 eDrive35 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 16.37 seconds. The 3.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
