Off the line, the A5 Avant hits 100 km/h in 7.72 s versus 7.75 s for the Bmw 420d Convertible. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 420d Convertible is doing 116 km/h against 122 km/h for the A5 Avant. The gap is 0.38 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Bmw 420d Convertible crosses the line in 15.64 s versus 15.70 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the situation changes. The Bmw 420d Convertible maxes out at 236 km/h while the A5 Avant keeps accelerating towards 245 km/h. At 600 metres, the gap has dropped to 0.23 s.
Around 442 metres, both vehicles are level. This is the inversion point: the A5 Avant overcomes its launch deficit thanks to a 9 km/h higher top speed.
At 1,000 metres, the A5 Avant finishes in 27.94 s versus 28.69 s. The 0.75 s delta in favour of the A5 Avant shows that top speed makes a clear difference.
Both rivals are electronically governed, but not at the same level: the A5 Avant is capped at 245 km/h, the Bmw 420d Convertible at 236 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 9.34 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 0.03 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.
