The start: 0 to 100 km/h

Off the line, the 540i xDrive hits 100 km/h in 4.96 s versus 7.79 s for the A5 Sedan. At this point, the 540i xDrive leads by 2.83 s and sits roughly 20 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 540i xDrive is doing 141 km/h against 117 km/h for the A5 Sedan. The gap is 1.64 s. The challenger starts to claw back ground.

At 400 metres standing start, the 540i xDrive crosses the line in 13.16 s versus 15.74 s. The 2.58 s gap represents roughly 100 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 540i xDrive continues to build its lead. At 600 metres, it runs at 198 km/h versus 162 km/h. At 1,000 metres, the 540i xDrive finishes in 23.73 s versus 28.62 s, with a 4.90 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 242 km/h), preventing any comeback.

What the numbers don’t tell you

The 540i xDrive features all-wheel drive (AWD) against the A5 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.

Both rivals are electronically governed, but not at the same level: the 540i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A5 Sedan at 242 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.24 kg/hp vs 8.92 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 2.83 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
