The start: 0 to 100 km/h

Off the line, the 520d hits 100 km/h in 7.56 s versus 7.93 s for the A6 Sedan. At this point, the 520d leads by 0.37 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 520d is doing 115 km/h against 115 km/h for the A6 Sedan. The gap is 0.40 s. The gap remains stable from the start.

At 400 metres standing start, the 520d crosses the line in 15.48 s versus 15.81 s. The 0.33 s gap represents roughly 13 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The 520d maxes out at 225 km/h while the A6 Sedan keeps accelerating towards 244 km/h. At 600 metres, the gap has dropped to 0.30 s.

At 1,000 metres, the 520d finishes in 28.71 s versus 28.86 s, with just 0.15 s to spare. The A6 Sedan fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the A6 Sedan is capped at 244 km/h, the 520d at 225 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 (9.36 kg/hp vs 9.37 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 0.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
