Volvo V90 review - MPG, CO2 and running costs

Volvo offers the V90 with a choice of four-cylinder diesel engines and the more modest of the pair, badged B4, manages up to 49.5mpg and emits from 148g/km of CO2. The 232bhp B5 is fitted to the heavier Cross Country version and isn't quite such an efficient set-up, returning 44.8mpg on the combined cycle and 164g/km of CO2.

The B4 and B5 petrol versions offer similar figures with average fuel economy hovering around the 40mpg mark and CO2 emissions from 158g/km, while the extra power of the 296bhp B6 means a reduction in efficiency to 35.3mpg and 182g/km of CO2.

Business users might be interested in the benefits of running the T6 plug-in petrol hybrid version, as its CO2 rating of 47g/km gives a Benefit-in Kind rating of 11% for 2021/22. The T6 is able to run on electric power alone for around 31-35 miles which, if you're able to keep the battery regularly topped up, will help reduce running costs on shorter commutes or driving around town.

Insurance groups

Petrol V90 cars are in groups 34 to 41, so it won't be particularly cheap to insure your Volvo estate. Diesel versions sit in groups 34-38, while the T6 plug-in hybrid are the most expensive to cover being in group 40-41.

Depreciation

Residual values for the V90 range aren't particularly strong, with an average of 40% of the original list price retained over three-years/36,000-miles. The T6 plug-in hybrid versions perform slightly better, holding onto around 46-47% over the same period.
