Off the line, the 540i xDrive hits 100 km/h in 4.96 s versus 7.28 s for the A4 40 TFSI. At this point, the 540i xDrive leads by 2.32 s and sits roughly 16 m ahead.
At 200 metres, the 540i xDrive is doing 141 km/h against 119 km/h for the A4 40 TFSI. The gap is 1.35 s. The challenger starts to claw back ground.
At 400 metres standing start, the 540i xDrive crosses the line in 13.16 s versus 15.36 s. The 2.20 s gap represents roughly 87 m of track - a gap visible to the naked eye.
Past 400 metres, the 540i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 165 km/h. At 1,000 metres, the 540i xDrive finishes in 23.73 s versus 28.08 s, with a 4.35 s lead.
The 540i 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 250 (i.e. 155 mph - industry threshold) km/h, the 540i 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 (5.24 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 2.32 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 540i xDrive G30 wins (4,96 s vs 7,28 s).
540i xDrive G30 goes from 0 to 100 km/h in 4,96 seconds (calibrated simulation).
