Off the line, the A5 Avant hits 100 km/h in 7.73 s versus 7.75 s for the 420d Convertible. The 0.02 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 420d Convertible is doing 116 km/h against 117 km/h for the A5 Avant. The gap is 0.12 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 420d Convertible crosses the line in 15.64 s versus 15.68 s. The 0.04 s gap represents roughly 1 m of track
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.08 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals are electronically governed, but not at the same level: the A5 Avant is capped at 240 km/h, the 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 (9.00 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 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
