The start: 0 to 100 km/h

Off the line, the i5 eDrive40 hits 100 km/h in 6.12 s versus 7.79 s for the A4 40 TDI. The instant torque of 400 Nm from the electric motor makes the difference. At this point, the i5 eDrive40 leads by 1.67 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i5 eDrive40 is doing 135 km/h against 122 km/h for the A4 40 TDI. The gap is 1.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the i5 eDrive40 crosses the line in 14.29 s versus 15.77 s. The 1.48 s gap represents roughly 61 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i5 eDrive40 continues to build its lead. At 600 metres, it runs at 186 km/h versus 171 km/h. At 1,000 metres, the i5 eDrive40 finishes in 25.87 s versus 28.08 s, with a 2.22 s lead. Despite a higher top speed (242 km/h), the A4 40 TDI never recovers its launch deficit.

What the numbers don’t tell you

Electronically capped at 193 km/h, the i5 eDrive40 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 11.76 seconds. The 1.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
