Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 24 - 44 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

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.

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.
