Off the line, the A3 Sedan hits 100 km/h in 6.21 s versus 6.22 s for the Bmw 128ti. The 0.01 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the A3 Sedan is doing 119 km/h against 136 km/h for the Bmw 128ti. The gap is 0.25 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 128ti crosses the line in 14.31 s versus 14.73 s. The 0.43 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the Bmw 128ti continues to build its lead. At 600 metres, it runs at 190 km/h versus 169 km/h. At 1,000 metres, the Bmw 128ti finishes in 25.37 s versus 27.19 s, with a 1.81 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 241 km/h), preventing any comeback.
On paper, the Bmw 128ti combines 265 hp, 400 Nm and 1,445 kg - a clear theoretical edge over the A3 Sedan. Yet the A3 Sedan launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the A3 Sedan has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
The A3 Sedan features all-wheel drive (AWD) against the Bmw 128ti’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 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 128ti 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 (5.45 kg/hp vs 7.13 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 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
