Off the line, the 225i xDrive hits 100 km/h in 6.41 s versus 7.28 s for the A4 40 TFSI. At this point, the 225i xDrive leads by 0.87 s and sits roughly 5 m ahead.
At 200 metres, the 225i xDrive is doing 128 km/h against 119 km/h for the A4 40 TFSI. The gap is 0.39 s. The challenger starts to claw back ground.
At 400 metres standing start, the 225i xDrive crosses the line in 14.60 s versus 15.36 s. The 0.76 s gap represents roughly 31 m of track - a gap visible to the naked eye.
Past 400 metres, the 225i xDrive continues to build its lead. At 600 metres, it runs at 177 km/h versus 165 km/h. At 1,000 metres, the 225i xDrive finishes in 26.49 s versus 28.08 s, with a 1.59 s lead. Both vehicles have similar top speeds (235 vs 232 km/h), preventing any comeback.
The 225i xDrive features all-wheel drive (AWD) against the A4 40 TFSI’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 225i xDrive 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 (6.58 kg/hp vs 7.97 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.78 seconds. The 0.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
