WLTP testing throws up a fuel-economy figure of 117.7mpg for the plug-in hybrid V90 T8, which you’re unlikely to match unless your daily commute is short and you can rely on the 29-mile electric range alone. It is, however, an impressive figure for what is a heavy and large car. When the petrol engine is running you can expect to see around 30-35mpg.

Volvo V90 T8 Twin Engine range

The V90 T8 is supported by a 10.4kWh battery pack, which results in a claimed electric range of 29 miles. You’ll find that it’s most effective to drive the car on battery power alone in urban environments, despite the claimed 78mph top speed when the car is in ‘Pure’ mode.

Of course, it depends on how you drive it and external conditions such as the temperature outdoors, but in real-world conditions you can expect around 20-25 miles on electric power before you’ll need to plug in, or set the engine to charge the battery (which will further dent your fuel economy) to get more electric miles.

Charge time

Plug the Volvo into a three-pin domestic socket and it’ll take around six hours to replenish the battery pack, but the charge rate is capped at 3.7kW, meaning two hours and 45 minutes is as fast as you can recharge the V90 T8’s batteries regardless of how powerful the fast charger might be. You have to pay £50 to get a Type 2 cable, which you'll need for public chargers.

The batteries are covered by an eight-year warranty, which includes free repairs for any ‘material defects’, but doesn't guarantee against loss of battery capacity over time, which can’t be avoided.
