The start: 0 to 100 km/h

Off the line, the A3 Sedan hits 100 km/h in 8.22 s versus 8.60 s for the 118i. Despite the faster sprint time, the 118i is 3 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 A3 Sedan is doing 119 km/h against 114 km/h for the 118i. The gap is 0.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the A3 Sedan crosses the line in 16.09 s versus 16.38 s. The 0.29 s gap represents roughly 11 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A3 Sedan continues to build its lead. At 600 metres, it runs at 168 km/h versus 158 km/h. At 1,000 metres, the A3 Sedan finishes in 28.62 s versus 29.71 s, with a 1.09 s lead.

What the numbers don’t tell you

Electronically capped at 213 km/h, the 118i 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 (8.60 kg/hp vs 9.21 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.79 seconds. The 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
