Volvo V90 T8 Twin Engine range, MPG, CO2 and charging

Impressive MPG and CO2 figures underline the V90 T8 Twin Engine’s capability as a day-to-day premium plug-in hybrid

Official testing throws up a fuel-economy figure of up to 166mpg for the plug-in hybrid V90 T8, but you’re unlikely to match that unless your daily commute is short and you can rely on the 35-mile electric range alone.

It is, however, an impressive figure for what is a pretty large and heavy 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 an 11.6kWh battery pack, which results in a claimed electric range of up to 35 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.

It depends on how you drive the car and external conditions such as the temperature, 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. A home wallbox will do it faster, but the charge rate is capped at 3.7kW, meaning just over three hours is as fast as you can recharge the V90 T8’s batteries, regardless of how powerful the charger you're plugged into 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.
