Off the line, the 320i xDrive hits 100 km/h in 7.51 s versus 7.72 s for the A5 Avant. At this point, the 320i xDrive leads by 0.21 s and sits roughly 16 m ahead.
At 200 metres, the 320i xDrive is doing 117 km/h against 122 km/h for the A5 Avant. The gap is 0.49 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 320i xDrive crosses the line in 15.47 s versus 15.70 s. The 0.23 s gap represents roughly 10 m of track - barely a car length.
Past 400 metres, the situation changes. The 320i xDrive maxes out at 228 km/h while the A5 Avant keeps accelerating towards 245 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 582 metres, both vehicles are level. This is the inversion point: the A5 Avant overcomes its launch deficit thanks to a 17 km/h higher top speed.
At 1,000 metres, the A5 Avant finishes in 27.94 s versus 28.46 s. The 0.52 s delta in favour of the A5 Avant shows that top speed makes a clear difference.
The 320i xDrive features all-wheel drive (AWD) against the A5 Avant’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 A5 Avant is capped at 245 km/h, the 320i xDrive at 230 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 (8.38 kg/hp vs 8.37 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.37 seconds. The 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
