Off the line, the Bmw 420i hits 100 km/h in 7.44 s versus 7.72 s for the A5 Avant. At this point, the Bmw 420i leads by 0.28 s and sits roughly 18 m ahead.
At 200 metres, the Bmw 420i is doing 117 km/h against 122 km/h for the A5 Avant. The gap is 0.55 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 420i crosses the line in 15.38 s versus 15.70 s. The 0.32 s gap represents roughly 14 m of track - two to three car lengths.
Past 400 metres, the situation changes. The Bmw 420i maxes out at 238 km/h while the A5 Avant keeps accelerating towards 245 km/h. At 600 metres, the gap has dropped to 0.11 s.
Around 707 metres, both vehicles are level. This is the inversion point: the A5 Avant overcomes its launch deficit thanks to a 7 km/h higher top speed.
At 1,000 metres, the A5 Avant finishes in 27.94 s versus 28.23 s. The 0.29 s delta shows an extremely tight race.
Both rivals are electronically governed, but not at the same level: the A5 Avant is capped at 245 km/h, the Bmw 420i at 240 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 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 0.28 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.
