The start: 0 to 100 km/h

Off the line, the A3 Sportback hits 100 km/h in 8.19 s versus 8.65 s for the 118d. At this point, the A3 Sportback leads by 0.46 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the A3 Sportback is doing 115 km/h against 113 km/h for the 118d. The gap is 0.34 s. The challenger starts to claw back ground.

At 400 metres standing start, the A3 Sportback crosses the line in 15.95 s versus 16.41 s. The 0.45 s gap represents roughly 18 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A3 Sportback continues to build its lead. At 600 metres, it runs at 161 km/h versus 157 km/h. At 1,000 metres, the A3 Sportback finishes in 28.98 s versus 29.82 s, with a 0.84 s lead. Both vehicles have similar top speeds (232 vs 218 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 218 km/h, the 118d 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 (9.40 kg/hp vs 9.37 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.03 seconds. The 0.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
