The A4 Avant, the estate of the A4s, is always up there. Refined, with terrific cabin quality, a range of engines that includes the very frugal, and a terrific and practical cruiser, it doesn’t have much against it apart from perhaps not being as much of an enjoyable driving experience as something like a BMW 3 Series. But with 15 models to choose from, which one should you go for?

Let’s start with the engines. These range from a 1.4 TSI petrol unit which works okay although you have to work it hard, up to the 3.0 TDI 272 diesel which is extremely rapid. There are a pair of 2.0-litre petrol engines and a pair of 2.0-litre diesel engines, all with different power outputs so there’s plenty of choice.

If we had to choose we’d go for the 3.0-litre TDI 218. So this isn’t the most powerful diesel but still shifts incredibly well and accelerates so strongly you’d wonder why you’d want a more powerful version.

Those diesel engines are also about the most refined you’ll find on the market, being quiet, smooth and just hugely impressive in their hushed performance. The petrol engines are pretty good, but nothing can match the Audi diesels.

In terms of transmissions, there are more choices, including the six-speed manual which is a smooth shifter, the S Tronic dual-clutch auto which works well but can be a touch jerky at low speed, and the Tiptronic auto which is a totally smooth performer.

But the choices don’t end there. There are four suspension set-ups. Passive sports suspension on lower models can be a bit firm, so we’d prefer the Comfort Dynamic as a good all-rounder. Further up there is Adaptive Comfort and Adaptive Sport so you can choose what suits your driving style. There is tons of traction and sharp steering whichever you choose.

Inside you’re sitting in a very practical and well-made cabin. For the money you won’t find a higher level of build or design. It feels luxurious beyond its price point, in everything from design to materials. In terms of space it’s a match for rivals like the C-Class Estate and the 3 Series Touring, with good room for occupants front and rear. The boot is bigger than most and is helped by having split folding rear seats as standard, along with a powered tailgate.

Kit levels are high, even with the lowest spec, while the highest S line trim gives you all the bells and whistles although not, surprisingly, full leather seating. The seats are comfortable and adjustable and there’s lots to keep you happy, although the infotainment system isn’t quite as intuitive as BMW’s iDrive.

It’s not a cheap vehicle, but it’s on a par with the main rivals. Residuals are excellent which gives it an edge for private buyers. The Ultra diesel engines really are economical, and there are benefits for company car drivers too. If we had to make a choice we’d go for the 3.0 TDI 218 as the best of a very good bunch.
