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 25 - 48 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.

Apart from some heavy initial depreciation, and some outrageous pricing for the V6 diesel models, the Vectra is a decent performer in a class where the bar is not set particularly high. The Volkswagen Passat and Honda Accord perform significantly better for depreciation but few others do. Four-cylinder diesels appear economical enough and the 2.2i offers good fuel consumption for a 155bhp petrol engine.

New 140bhp 1.8i is actually more economical than the less powerful engine it replaces, although it’s also one insurance group higher.

Vectra performs quite well on the eco front. With an average of 185 g/km CO2 across the line-up, its emissions are fairly standard 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 39mpg.

A properly serviced Vectra should prove reliable.
