Off the line, the A5 Avant hits 100 km/h in 7.72 s versus 8.33 s for the 318i Sedan. Despite the faster sprint time, the 318i Sedan is 7 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 318i Sedan is doing 113 km/h against 122 km/h for the A5 Avant. The gap is 0.08 s. The challenger starts to claw back ground.
At 400 metres standing start, the A5 Avant crosses the line in 15.70 s versus 16.06 s. The 0.36 s gap represents roughly 14 m of track - two to three car lengths.
Past 400 metres, the A5 Avant continues to build its lead. At 600 metres, it runs at 172 km/h versus 157 km/h. At 1,000 metres, the A5 Avant finishes in 27.94 s versus 29.44 s, with a 1.50 s lead.
Both rivals are electronically governed, but not at the same level: the A5 Avant is capped at 245 km/h, the 318i Sedan at 223 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 9.55 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.71 seconds. The 0.61 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
