Dislikes
  • Mild-hybrid interesting, but not a game-changer
  • Active cruise extra cost in premium version. Should be standard
  • Sportback looks don’t flatter the car

  • Space-saver tyre
  • Short warranty
  • Paying extra for driver-assist tech
2022 Audi A3 Summary

If it was the original BMW 3-Series that invented the compact luxury car market segment all those years ago, then it’s probably fair to claim it was Audi’s A3 franchise that gave rise to the luxury small-hatch category.

On that basis, any new Audi A3 is news but, in the face of the SUV onslaught (including its own stablemate the Q3) the new small Audi has its work cut out for it.

With this update, there’s refreshed styling, a new interior layout and, for the launch of the new cars, two body styles, a conventionally styled sedan and what Audi calls the Sportback; fundamentally a five-door hatchback but with the German brand’s own flair plastered all over it.

As well as new connectivity and safety tech, the big news is the availability of a mild-hybrid driveline as well as a second powertrain option with more performance from a more conventional layout.

Interestingly, it’s that (mild) hybrid version of the A3 that represents the entry-level variant of the A3. A sign of the times? Perhaps.

As well as the two powertrains, there are two distinct chassis layouts, starting with a front-drive set-up and extending to the option of Audi’s Quattro all-wheel drive (AWD) system.

2021 Audi A4 Summary

The Audi A4 allroad is the off-roader of the A4 line-up. I’m using the term ‘off-roader’ loosely here because this wagon is obviously best suited to daily duties in a city and suburbs, with perhaps an occasional foray into very light off-roading, i.e. driving on a well-maintained gravel or dirt road with few, if any, corrugations, and in dry weather only. 

But that’s not a negative factor because the great thing about adventures is that they can be scaled to suit you, your lifestyle and your vehicle of choice.

However, is this allroad your best option for a comfortable, nice-driving all-rounder? Read on.
