The start: 0 to 100 km/h

Off the line, the A3 allstreet hits 100 km/h in 8.38 s versus 8.74 s for the 118i. At this point, the A3 allstreet leads by 0.36 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the A3 allstreet is doing 114 km/h against 114 km/h for the 118i. The gap is 0.33 s. The gap remains stable from the start.

At 400 metres standing start, the A3 allstreet crosses the line in 16.10 s versus 16.47 s. The 0.37 s gap represents roughly 14 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A3 allstreet continues to build its lead. At 600 metres, it runs at 159 km/h versus 157 km/h. At 1,000 metres, the A3 allstreet finishes in 29.31 s versus 29.84 s, with a 0.53 s lead. Both vehicles have similar top speeds (223 vs 213 km/h), preventing any comeback.

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 (9.57 kg/hp vs 9.49 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.99 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
