Audi A6 Avant vs BMW 220d xDrive Gran Coupe F44: which is truly faster?

Off the line, the A6 Avant hits 100 km/h in 7.00 s versus 7.43 s for the 220d xDrive Gran Coupe. At this point, the A6 Avant leads by 0.43 s and sits roughly 13 m ahead.

At 200 metres, the A6 Avant is doing 117 km/h against 118 km/h for the 220d xDrive Gran Coupe. The gap is 0.44 s. The gap remains stable from the start.

At 400 metres standing start, the A6 Avant crosses the line in 15.02 s versus 15.43 s. The 0.41 s gap represents roughly 17 m of track - two to three car lengths.

Past 400 metres, the gap narrows. The 220d xDrive Gran Coupe maxes out at 231 km/h while the A6 Avant keeps accelerating towards 238 km/h. At 600 metres, the gap has dropped to 0.35 s.

At 1,000 metres, the A6 Avant finishes in 27.98 s versus 28.31 s, with just 0.33 s to spare. The 220d xDrive Gran Coupe fails to fully close the launch gap.

Both rivals are electronically governed, but not at the same level: the A6 Avant is capped at 238 km/h, the 220d xDrive Gran Coupe at 234 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 (9.80 kg/hp vs 8.24 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.14 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
