Volvo S90 T8 Twin Engine running costs

The Volvo S90 T8 offers big saloon-car practicality and a beautiful interior, but the diesel versions are just as economical and cheaper to buy

Insurance group Warranty Service intervals 2019/20 company-car cost (20%/40%)
44 3yrs / 60,000 miles 1yr / 18,000 miles From £1,843 / £3,686

With a starting price of over £57,000, the Volvo S90 T8 Twin Engine isn’t a cheap car to buy, but with the exception of insurance, running costs should be less than for other S90 models or rival products. They need to be, because BMW 530e prices start from under £47,000 and the Mercedes E-Class hybrid is only slightly more.

The low running costs are mainly down to the fact that the T8 emits just 40g/km of CO2, attracting a Benefit-in-Kind (BiK) rate of only 13%. Fuel economy is quoted at a maximum of 166mpg, but in common with other plug-in hybrids, it can be hard to match this in real-world driving.

In reality, you’re likely to see anything between 30 and 50mpg, depending on how you drive, although the ability to cover as much as 35 miles in electric mode should lower fuel costs. The S90 T8’s CO2 figure means it's exempt from the London Congestion Charge – but only until October 2021.

Volvo S90 T8 Twin Engine insurance group

All versions of the S90 T8 fall into insurance group 44, making them by far the most expensive S90 models to insure. Other S90s range from groups 28 to 37, depending on engine and trim level. Volvo offers its own insurance cover, guaranteeing the use of genuine parts and repairs covered by a five-year warranty.

Warranty

The S90 T8 is covered by Volvo’s standard three-year/60,000-mile warranty, but this can be extended to four-year/60,000-mile or four-year/80,000-mile cover for an additional price. The battery in the T8 is covered by its own eight-year/100,000-mile warranty, with any material defects fixed for free within that period.

Servicing

The Volvo S90 T8 Twin Engine requires a service every 12 months or 18,000 miles, whichever comes sooner.

Road tax

There’s no road tax to pay in year one, but CO2 emissions of 40g/km and the over-£40,000 list price equate to £455 a year in years two to six of ownership, dropping to £135 a year after that.
