Servicing is not cheap. Engines can be tricky to work on, so not one for the DIYer. Fuel economy is so-so because of the big bodies – mpg is low 30s for 1.8/2.0 (although the latest 2.0 HPi unit manages over 35mpg), low 40s for the 1.9/2.1 turbo-diesels, slightly better for the later 2.0 HDi diesels.

406 performs quite well on the eco front. With an average of 180 g/km CO2 across the line-up, its emissions are quite low for a medium-sized estate. 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 also fairly economical, averaging 39 mpg.

An enviable reliability record so far – most have been maintained properly by fleet managers; the long-term outlook is looking good so far, but time and mounting mileages will tell.
