The start: 0 to 100 km/h

Off the line, the 540d xDrive hits 100 km/h in 4.64 s versus 7.00 s for the A6 Avant. At this point, the 540d xDrive leads by 2.37 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 540d xDrive is doing 142 km/h against 117 km/h for the A6 Avant. The gap is 1.15 s. The challenger starts to claw back ground.

At 400 metres standing start, the 540d xDrive crosses the line in 12.90 s versus 15.02 s. The 2.12 s gap represents roughly 82 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 540d xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 161 km/h. At 1,000 metres, the 540d xDrive finishes in 23.41 s versus 27.98 s, with a 4.57 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 540d xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A6 Avant at 238 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 (5.44 kg/hp vs 9.80 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.76 seconds. The 2.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
