Audi A4

What is the Audi A4?

The A4 is Audi’s mid-size family car, offered as a saloon and an Avant estate. The saloon suits everyday commuting, while the estate gives passengers and luggage more room. The A4 replaced the Audi 80 and became a central model in Audi’s mid-size range.

The generations listed here are the B5 (1995–2001), B6 (2000–2006), B7 (2004–2009), B8 (2007–2016) and B9 (since 2015). The dates overlap as one generation gave way to the next. The saloon and Avant estate remained key body styles through those generations, as engine and equipment choices changed.

Engines and power

A4 powertrains have ranged from smaller petrol and diesel engines to higher-output versions. In the EU, engine sizes span 1.4 to 3.2 litres and power ranges from 88 kW (120 PS) to 331 kW (450 PS). The UK range spans 1.4 to 3.2 litres and 75 kW (102 PS) to 245 kW (333 PS). Fuel choices vary by market: EU figures include petrol, diesel, hybrid, plug-in hybrid, natural gas and E85 flex fuel; UK figures cover petrol and diesel, while US figures include petrol, hybrid and E85 versions.

How economical is the Audi A4?

The lowest listed EU consumption for petrol, diesel and hybrid versions is 4.5 L/100 km on WLTP. The UK low is 3.8 L/100 km on NEDC, and the French low is 4 L/100 km, also on NEDC. In the USA, the best combined EPA rating is 31 MPG, with a listed low of 7.6 L/100 km. Canada’s lowest listed result is also 7.6 L/100 km on its 5-cycle test.

The procedures differ: Europe uses WLTP or NEDC, the USA uses EPA testing, and Canada uses its 5-cycle procedure. EU registration figures cover the A4 from 2010 onward, with 2.0-litre diesel versions among the highest-registration entries.
