Fuel economy is likely to be the biggest influencer of Audi A4 Saloon running costs, and the range of official combined mpg figures makes for pleasant reading.
The worst you’re likely to encounter in an A4 is the 36.7mpg figure offered by the 354hp 3.0-litre turbocharged V6 petrol engine fitted with an eight-speed Tiptronic automatic gearbox and Quattro four-wheel drive.
If you want an economical petrol model, your best bet is the 1.4-litre TFSI with 150hp offered in both SE and Sport trims. This returns a claimed 53.3mpg, just edging the 190hp 2.0-litre TFSI S tronic on 52.3mpg.
Those who are keen on diesel powerplants will be happy whatever their choice, with the 2.0-litre 150hp TDI Ultra capable of 74.3mpg. Thanks to low emissions, annual VED car tax will also be low.
If saving the world is a priority, then good news – Audi A4’s emissions are impressively low across the range and the new car is up to 120kg lighter than the model that came before. The bad news however, is that – for now – there is no hybrid or pure electric version on offer.
There are a variety A4 saloons fitted with Ultra engines to choose from, thanks to the SE, Sport and S Line trims and choice of manual and automatic gearboxes.
There are two outputs available for the 2.0-litre four-cylinder TDI diesel engine, the 150hp Ultra model emitting as little as 99g/km of CO2 when fitted with a six-speed manual in the SE model and up to 101g/km with the seven-speed S Tronic dual-clutch automatic. Choosing the S Line, with its larger wheels, increases that number to 106g/km and 109g/km, respectively.
- Mixture of tried-and-tested and new engines for the A4
- Audi generally has a reputable reliability record
- Some recent Audis have suffered from electrical maladies
Dig back far enough and its history can be traced back to the 1972 Audi 80; 12 million examples later we’d expect Audi A4 Saloon reliability to be fine. After all this is as mainstream as Audi’s models get, so success is crucial to the car – and the last model suffered just two recalls, one for its airbags and another for its brakes.
The engines are a mix of all-new units and those seen elsewhere in the Volkswagen Group range, with no reported major issues, yet – these ones aren’t affected by the Dieselgate scandal.
Inside the cabin is constructed from solid and hard-wearing materials. Our only concern would surround the (optional) Virtual Cockpit system and the electrics involved, which saw some early Audi TT models experience occasional problems.
Estimated fuel cost per year
|Fuel type||Pence per litre||Estimated cost per year *|
|Unleaded||128p||£1,058 - £1,616 *|
|Diesel||131p||£805 - £1,145 *|
* The estimated fuel cost figure is based on an annual mileage of 10,000 miles and is a guide to how much this model will cost in fuel each year. It's calculated using the model's average MPG (calculated from both town centre and motorway driving) and the average fuel price from around the country. Actual fuel costs will vary based on driving style and road conditions.

How much is it to insure?
Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
