Off the line, the 320d Steptronic hits 100 km/h in 6.97 s versus 7.79 s for the A4 40 TDI. At this point, the 320d Steptronic leads by 0.82 s and sits roughly 21 m ahead.
At 200 metres, the 320d Steptronic is doing 120 km/h against 122 km/h for the A4 40 TDI. The gap is 0.76 s. The gap remains stable from the start.
At 400 metres standing start, the 320d Steptronic crosses the line in 15.10 s versus 15.77 s. The 0.67 s gap represents roughly 28 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The 320d Steptronic maxes out at 237 km/h while the A4 40 TDI keeps accelerating towards 242 km/h. At 600 metres, the gap is down to 0.57 s from 0.67 s at 400 metres.
At 1,000 metres, the 320d Steptronic finishes in 27.70 s versus 28.08 s, with just 0.38 s to spare. The A4 40 TDI fails to fully close the launch gap.
Electronically capped at 240 km/h, the 320d Steptronic 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 (8.29 kg/hp vs 7.66 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 0.82 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
