The start: 0 to 100 km/h

Off the line, the 420d hits 100 km/h in 7.04 s versus 7.72 s for the A5 Sedan. At this point, the 420d leads by 0.68 s and sits roughly 22 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 420d is doing 119 km/h against 122 km/h for the A5 Sedan. The gap is 0.75 s. The gap remains stable from the start.

At 400 metres standing start, the 420d crosses the line in 15.10 s versus 15.71 s. The 0.61 s gap represents roughly 25 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The 420d maxes out at 240 km/h while the A5 Sedan keeps accelerating towards 247 km/h. At 600 metres, the gap is down to 0.47 s from 0.61 s at 400 metres.

At 1,000 metres, the 420d finishes in 27.77 s versus 27.99 s, with just 0.22 s to spare. The A5 Sedan fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the A5 Sedan is capped at 248 km/h, the 420d 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 (8.31 kg/hp vs 8.45 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 0.68 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
