The Audi A4 Cabriolet is all about understated elegance. It's smooth, refined, has a well designed interior and comes with some fine petrol and diesel engines.

Running costs

Our figures show that the previous A4 Convertible held its value well and usually better than the equivalent BMW 3-Series models and Mercedes-Benz CLK. Fuel economy is acceptable from all engines (taking into account size and performance) and is particularly good in the two diesels. Service intervals are dictated by the on-board computer which means that the harder you drive it, the shorter they will be.

Emissions summary

The A4 is quite a polluting model. With an average of 219g/km CO2 across the range, its emissions are a touch high for a sports cabriolet. However, it's worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

The range is not very frugal either, averaging 33mpg.
