Off the line, the 420i hits 100 km/h in 7.44 s versus 9.98 s for the A5 Sedan. At this point, the 420i leads by 2.54 s and sits roughly 30 m ahead.
At 200 metres, the 420i is doing 117 km/h against 108 km/h for the A5 Sedan. The gap is 1.44 s. The challenger starts to claw back ground.
At 400 metres standing start, the 420i crosses the line in 15.38 s versus 17.30 s. The 1.92 s gap represents roughly 69 m of track - a gap visible to the naked eye.
Past 400 metres, the 420i continues to build its lead. At 600 metres, it runs at 163 km/h versus 150 km/h. At 1,000 metres, the 420i finishes in 28.23 s versus 31.28 s, with a 3.05 s lead.
Both rivals are electronically governed, but not at the same level: the 420i is capped at 240 km/h, the A5 Sedan at 216 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 (8.29 kg/hp vs 11.30 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.30 seconds. The 2.54 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i F32 wins (7,44 s vs 9,98 s).
420i F32 goes from 0 to 100 km/h in 7,44 seconds (calibrated simulation).
