2020 Audi A4 Allroad badge

The Allroad features engines and gearboxes that can be found in several other Audi models, where there have been few significant issues so far. Plus, the overall feel of the latest A4 range is one of solidity and high quality, which should allay any fears you have of interior rattles and squeaks becoming known.

We’ve previously experienced some issues with the firm’s Virtual Cockpit system, but this was on earlier models, and the A4 features the latest, updated system, so any software or technical issues should have been ironed out. If you do have any problems, all A4 Allroads come with a three-year, 60,000-mile warranty.
