Off the line, the A3 Sedan hits 100 km/h in 8.22 s versus 8.33 s for the Bmw 318i. Despite the faster sprint time, the Bmw 318i is 13 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 318i is doing 113 km/h against 119 km/h for the A3 Sedan. The gap is 0.36 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 318i crosses the line in 16.06 s versus 16.09 s. The 0.03 s gap represents roughly 1 m of track
Past 400 metres, the situation changes. The Bmw 318i maxes out at 223 km/h while the A3 Sedan keeps accelerating towards 240 km/h. At 600 metres, the gap has dropped to 0.27 s.
Around 418 metres, both vehicles are level. This is the inversion point: the A3 Sedan overcomes its launch deficit thanks to a 17 km/h higher top speed.
At 1,000 metres, the A3 Sedan finishes in 28.62 s versus 29.44 s. The 0.82 s delta in favour of the A3 Sedan shows that top speed makes a clear difference.
Electronically capped at 223 km/h, the Bmw 318i 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 (9.55 kg/hp vs 8.60 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.71 seconds. The 0.11 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
