  • Entry-level B4 will be the cheapest diesel to run
  • Lot of merit for basic petrol
  • Plug-in hybrid T6 great in theory

On paper the T6 plug-in hybrid Volvo V90 offers the lowest running costs with a claimed average of 134.5mpg. However, that really depends on how the owner uses the car. We found that on a typical start stop journey of around 10 miles it would average more than 100mpg. However, on longer motorway journeys you soon burn through the electrical assistance. Expect not much more than 33mpg once the juice has run out.

The B4 is the most frugal non-plug-in, thanks to a claimed 49.6mpg. Choose the B5 with more power and all-wheel drive system and the official figure drops to 47.1mpg.

B4 mild hybrid petrol - 40.9mpg

B4 mild hybrid diesel - 49.6mpg

B5 mild hybrid petrol - 40.4mpg

B5 mild hybrid diesel AWD - 47.1mpg

B6 mild hybrid petrol AWD - 36.2mpg

T6 plug-in hybrid AWD - 134.5mpg, 35.4 miles electric range

CO2 emissions

Like with mpg, the plug-in hybrid is darling of the V90 range in terms of CO2 emissions. This ultimately depends on how you use it. If you never charge it, you're not really producing a mere 47g/km. The T6 does get you into the highly desirable 10% BIK classification for company cars, if that matters to you.

B4 mild hybrid petrol - 158g/km

B4 mild hybrid diesel - 149g/km

B5 mild hybrid petrol - 160g/km

B5 mild hybrid diesel AWD - 158g/km

B6 mild hybrid petrol AWD - 178g/km

T6 plug-in hybrid AWD - 47g/km


  • Underpinnings have also seen service with XC90
  • Mechanical packages should prove to be reliable
  • Minor recalls

On the whole the interior feels very well screwed together and the materials, although luxurious, feel tough and durable. Although the engines have been updated prior to their installation in the 90-series models, Volvo’s got a long history of turbocharging and all-wheel drive systems.

At time of writing (December 2020) the V90 has had four recalls. Two are relating to airbags, one a software glitch, and another about a plastic inlet manifold that could melt. If you're buying a new car, all of these things will have been fixed. If you're buying a used one, there's a 99.9% chance these have all been seen to. However, it's always worth checking.
