Off the line, the Bmw 120i hits 100 km/h in 6.91 s versus 8.38 s for the A3 allstreet. At this point, the Bmw 120i leads by 1.47 s and sits roughly 9 m ahead.
At 200 metres, the Bmw 120i is doing 124 km/h against 114 km/h for the A3 allstreet. The gap is 0.63 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 120i crosses the line in 15.02 s versus 16.10 s. The 1.08 s gap represents roughly 42 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 120i continues to build its lead. At 600 metres, it runs at 174 km/h versus 159 km/h. At 1,000 metres, the Bmw 120i finishes in 27.09 s versus 29.31 s, with a 2.22 s lead. Both vehicles have similar top speeds (235 vs 223 km/h), preventing any comeback.
Electronically capped at 235 km/h, the Bmw 120i 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 (7.81 kg/hp vs 9.57 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.44 seconds. The 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
