MPG, running costs & CO2 Rating

4.0 out of 5

Compare the Volvo S90 to its main rivals, such as the Jaguar XF, BMW 5 Series, Mercedes E-Class and Audi A6 and it acquits itself reasonably well. Its fuel efficiency figures are similar to those of similarly powered rivals, as are its CO2 numbers. The figures that the forthcoming plug-in hybrid version is likely to be capable of achieving under laboratory conditions will be very impressive. How possible they’ll be in the real world, however, is another matter.

Volvo S90 MPG & CO2

There are two diesel engines to choose from in the Volvo S90 range. They make either 190 and 235bhp and offer perfectly reasonable fuel economy and CO2 emissions, but they’re not class-leading in any way. The 187bhp version will return around 50mpg and has CO2 emissions of 121g/km. Annual road tax is £140, while company-car users will be liable for 29% Benefit-in-Kind (BiK) tax contributions.

You can only have this version with an eight-speed automatic gearbox and front-wheel drive, so if we compare it to similarly set up rivals, it performs reasonably. It’s slightly behind the best efforts of the latest Jaguar XF and a fair way behind the Mercedes E-Class’ best of 61.4mpg and CO2 emissions of 122g/km.

The T4 petrol engine returns up to 37.7mpg, emits 155g/km of CO2 and is around the same price to buy as the equivalent D4 diesel. A hefty first-year tax payment of £515 applies; this is usually rolled into the on-the-road price. Its BiK rating is 32%. The T5 is more powerful, but the same 37.7mpg fuel consumption means it shouldn't cost any more to run.

If you go for the more powerful D5 PowerPulse S90 diesel, you get four-wheel drive as standard, which, unsurprisingly, reduces fuel efficiency and increases CO2 emissions. This version will manage around 43.5mpg and has CO2 emissions of 142g/km, which puts it about on par, if not slightly ahead of, other four-wheel-drive rivals. Business users will be liable for the 34-35% BiK rate.


Like most cars, the S90 will need servicing every year, and if you get it serviced at a main dealer (there are 120 across the UK, so you shouldn’t have to travel too far to find one) it’s covered by what’s known as the Volvo Service Promise. This guarantees the use of original Volvo parts, as well as a complete vehicle health check and a software upgrade alongside the mechanical servicing that’s required. There are also a number of service plans that can be used to spread the cost of servicing.


The Volvo S90’s warranty is okay – the car is covered for three years or 60,000 miles (whichever comes first), putting it on par with the Audi A6 – but it’s a little behind its rivals from Jaguar, Mercedes and BMW, none of which put a mileage limit on their warranties.

Insurance group

Depending on which model you go for, the S90 will be in groups 27 to 33, which should make it reasonably affordable to insure relative to its rivals. The Audi A6 sits in higher insurance groups, as does a diesel BMW 5 Series, while the Jaguar XF starts a couple of groups lower than the Volvo.
