Off the line, the A3 allstreet hits 100 km/h in 7.44 s versus 7.44 s for the Bmw 420i. The instant torque of 350 Nm from the electric motor makes the difference. The 0.00 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 420i is doing 117 km/h against 120 km/h for the A3 allstreet. The gap is 0.36 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 15.61 s. The 0.23 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the situation changes. The A3 allstreet maxes out at 230 km/h while the Bmw 420i keeps accelerating towards 238 km/h. At 600 metres, the gap has dropped to 0.10 s.
Around 788 metres, both vehicles are level. This is the inversion point: the A3 allstreet overcomes its launch deficit thanks to a 8 km/h higher top speed.
At 1,000 metres, the A3 allstreet finishes in 28.13 s versus 28.23 s. The 0.09 s delta shows an extremely tight race.
Electronically capped at 240 km/h, the Bmw 420i 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, A3 allstreet and 420i F32 are neck and neck (7,44 s vs 7,44 s, no significant gap).
A3 allstreet goes from 0 to 100 km/h in 7,44 seconds (calibrated simulation).
