Off the line, the Bmw X3 M40i hits 100 km/h in 4.78 s versus 9.87 s for the A3 Sedan. At this point, the Bmw X3 M40i leads by 5.09 s and sits roughly 30 m ahead.
At 200 metres, the Bmw X3 M40i is doing 142 km/h against 108 km/h for the A3 Sedan. The gap is 2.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X3 M40i crosses the line in 13.02 s versus 17.21 s. The 4.19 s gap represents roughly 146 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X3 M40i continues to build its lead. At 600 metres, it runs at 197 km/h versus 150 km/h. At 1,000 metres, the Bmw X3 M40i finishes in 23.67 s versus 31.24 s, with a 7.56 s lead.
The Bmw X3 M40i features all-wheel drive (AWD) against the A3 Sedan’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 X3 M40i 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 (5.13 kg/hp vs 11.68 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.25 seconds. The 5.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40i G01 wins (4,78 s vs 9,87 s).
X3 M40i G01 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
