Off the line, the 320i Sedan hits 100 km/h in 7.02 s versus 7.79 s for the A5 Sedan. At this point, the 320i Sedan leads by 0.77 s and sits roughly 13 m ahead.
At 200 metres, the 320i Sedan is doing 120 km/h against 117 km/h for the A5 Sedan. The gap is 0.55 s. The challenger starts to claw back ground.
At 400 metres standing start, the 320i Sedan crosses the line in 15.09 s versus 15.74 s. The 0.65 s gap represents roughly 26 m of track - two to three car lengths.
Past 400 metres, the 320i Sedan continues to build its lead. At 600 metres, it runs at 166 km/h versus 162 km/h. At 1,000 metres, the 320i Sedan finishes in 27.74 s versus 28.62 s, with a 0.88 s lead. Both vehicles have similar top speeds (242 vs 235 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the A5 Sedan is capped at 242 km/h, the 320i Sedan at 235 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 (8.92 kg/hp vs 8.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 0.77 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
