Off the line, the A6 Sedan hits 100 km/h in 8.16 s versus 8.23 s for the XC40 B4. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the XC40 B4 is doing 115 km/h against 119 km/h for the A6 Sedan. The gap is 0.16 s. The gap widens compared to the 0-100.
At 400 metres standing start, the A6 Sedan crosses the line in 16.06 s versus 16.10 s. The 0.05 s gap represents roughly 2 m of track
Past 400 metres, the A6 Sedan continues to build its lead. At 600 metres, it runs at 167 km/h versus 158 km/h. At 1,000 metres, the A6 Sedan finishes in 28.62 s versus 29.39 s, with a 0.77 s lead.
Both rivals are electronically governed, but not at the same level: the A6 Sedan is capped at 244 km/h, the XC40 B4 at 180 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 (8.68 kg/hp vs 8.17 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.40 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, A6 Sedan and XC40 B4 are neck and neck (8,16 s vs 8,23 s, no significant gap).
A6 Sedan goes from 0 to 100 km/h in 8,16 seconds (calibrated simulation).
