Off the line, the A3 Sedan hits 100 km/h in 6.21 s versus 6.91 s for the Bmw 120i. At this point, the A3 Sedan leads by 0.70 s and sits roughly 15 m ahead.
At 200 metres, the A3 Sedan is doing 119 km/h against 124 km/h for the Bmw 120i. The gap is 0.51 s. The challenger starts to claw back ground.
At 400 metres standing start, the A3 Sedan crosses the line in 14.73 s versus 15.02 s. The 0.29 s gap represents roughly 12 m of track — two to three car lengths.
Past 400 metres, the situation changes. The Bmw 120i maxes out at 235 km/h while the A3 Sedan keeps accelerating towards 241 km/h. At 600 metres, the gap has dropped to 0.12 s.
Around 809 metres, both vehicles are level. This is the inversion point: the Bmw 120i overcomes its launch deficit thanks to a 6 km/h higher top speed.
At 1,000 metres, the Bmw 120i finishes in 27.09 s versus 27.19 s. The 0.10 s delta shows an extremely tight race.
The A3 Sedan features all-wheel drive (AWD) against the Bmw 120i’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
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 (7.13 kg/hp vs 7.81 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 0.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
