Off the line, the 320i hits 100 km/h in 7.05 s versus 7.72 s for the A5 Sedan. At this point, the 320i leads by 0.67 s and sits roughly 21 m ahead.
At 200 metres, the 320i is doing 119 km/h against 122 km/h for the A5 Sedan. The gap is 0.73 s. The gap remains stable from the start.
At 400 metres standing start, the 320i crosses the line in 15.11 s versus 15.71 s. The 0.60 s gap represents roughly 25 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The 320i maxes out at 234 km/h while the A5 Sedan keeps accelerating towards 247 km/h. At 600 metres, the gap is down to 0.46 s from 0.60 s at 400 metres.
At 1,000 metres, the 320i finishes in 27.81 s versus 27.99 s, with just 0.19 s to spare. The A5 Sedan fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the A5 Sedan is capped at 248 km/h, the 320i 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 (8.31 kg/hp vs 7.93 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.72 seconds. The 0.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
