The start: 0 to 100 km/h

Off the line, the A4 40 TFSI hits 100 km/h in 7.28 s versus 7.46 s for the 320e. Despite lacking instant torque, 190 hp of power compensates. Despite the faster sprint time, the 320e is 6 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the 320e is doing 115 km/h against 119 km/h for the A4 40 TFSI. The gap is 0.14 s. The gap remains stable from the start.

At 400 metres standing start, the A4 40 TFSI crosses the line in 15.36 s versus 15.43 s. The 0.08 s gap represents roughly 3 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A4 40 TFSI continues to build its lead. At 600 metres, it runs at 165 km/h versus 158 km/h. At 1,000 metres, the A4 40 TFSI finishes in 28.08 s versus 28.77 s, with a 0.69 s lead.

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.

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 12.74 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
