Off the line, the 125i hits 100 km/h in 6.15 s versus 9.90 s for the A3 Sportback. At this point, the 125i leads by 3.75 s and sits roughly 24 m ahead.
At 200 metres, the 125i is doing 131 km/h against 108 km/h for the A3 Sportback. The gap is 1.80 s. The challenger starts to claw back ground.
At 400 metres standing start, the 125i crosses the line in 14.35 s versus 17.23 s. The 2.87 s gap represents roughly 102 m of track - a gap visible to the naked eye.
Past 400 metres, the 125i continues to build its lead. At 600 metres, it runs at 182 km/h versus 149 km/h. At 1,000 metres, the 125i finishes in 25.91 s versus 31.33 s, with a 5.43 s lead.
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 11.68 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.37 seconds. The 3.75 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
