  • Official running cost figures yet to be confirmed for 2019
  • Pre-facelift cars claimed impressive figures
  • Two new diesel engines should be cheap to run

Before the car’s facelift in 2019, the diesel range in the A4 Avant proved to be economical and cheap to run – especially in Ultra form. While full figures are yet to be confirmed for the updated range, we’d expect the diesels to remain the best performers in terms of fuel consumption – especially the new 2.0-litre TDI unit found in the 30 TDI and 35 TDI.

The 35 TDI is expected to return between 48 and 54mpg when fitted with the S Tronic automatic gearbox, while the higher-output 40 TDI with Quattro should return 44-47mpg. As is always the case, the size of the alloy wheels can impact the fuel consumption of the car.

The figures should match up similarly with those of the A4 Saloon, so the petrol range should vary from around 45-50mpg for the 35 TFSI and around 38-42mpg for the 40 TFSI. Higher up the range is the 45 TFSI which should be closer to 35mpg.

We’ll fill this page with official claimed economy figures when they’re made available.

Is it reliable?

  • Many components already seeing service elsewhere
  • Audi’s reliability record remains an enviable one
  • Some recent technology has suffered from niggles, though

Audi A4 Avant reliability has proven to have been strong over the previous four generations of the car, the last version subject to a couple of recalls related to potential issues with brakes and airbags.

Many of the engines and gearboxes employed have seen service in other Volkswagen Group products but the new motors are based on years of painstaking research – no significant issues are expected.

Should you opt for the digital instrumentation of the Virtual Cockpit, be aware that many Audi TTs have suffered niggles with their systems, including the one fitted to our long-term test example.

As for other reliability aspects, we expect the Avant to remain close to the Audi A4 Saloon.
