Off the line, the 125i hits 100 km/h in 6.15 s versus 6.21 s for the A3 Sedan. The 0.06 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the A3 Sedan is doing 119 km/h against 131 km/h for the 125i. The gap is 0.11 s. The gap remains stable from the start.
At 400 metres standing start, the 125i crosses the line in 14.35 s versus 14.73 s. The 0.38 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 169 km/h. At 1,000 metres, the 125i finishes in 25.91 s versus 27.19 s, with a 1.28 s lead. Both vehicles have similar top speeds (243 vs 241 km/h), preventing any comeback.
Electronically capped at 243 km/h, the 125i 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 (6.25 kg/hp vs 7.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.24 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
