Volvo S90 T8 Twin Engine range, MPG, CO2 & charging

A useful electric-only range and low CO2 emissions make the Volvo S90 T8 Twin Engine a compelling prospect for real-world driving

Volvo’s model range was designed with electrification in mind, so the S90 T8 is a no-compromise plug-in hybrid. Short, daily commutes to the office or station can be completed in pure electric mode, while home charging can take as little as 3.5 hours.

Volvo S90 T8 Twin Engine range

Volvo claims that it’s possible to travel 29 miles on electric power, but it’s best to take this figure with a pinch of salt. Achieving this will require a light foot, a fully charged battery and flat roads. The range will drop in the winter, if your journey includes hills or faster main roads, and if you make use of some of the car’s features, such as the heated seats and climate control.

The Volvo S90 T8 could, in theory, offer the best of both worlds. A zero-emission commuting vehicle for trips to the railway station or office during the week, and a family car for longer trips at weekends, with the added bonus of this being the most powerful model in the S90 range.

Charge time

The S90 T8 comes with a 10.4kWh lithium-ion battery and can be charged from a household socket using the 4.5-metre charging cable supplied. The charging point can be found on the nearside front wing of the T8. Fully charging using a standard three-pin plug will take around six hours, and you can also buy a 4.5-metre Type 2 charging cable for £50, which provides access to the rapid chargers found in motorway services.

But, with a 3.5kW on-board charger as standard, the S90 will only ever charge at a maximum speed of 3.5kW, meaning that even plugging it into a 43kW fast charger (the fastest AC charger, and often found at motorway services), it'll take 2.5 hours or more to charge. You can't plug in a CCS charging cable – only a Type 2, but that gives you access to almost all public charging points.

Additional range can be achieved by pressing the brake pedal while driving or when coasting. Further recharging is available by selecting ‘B’ mode, which activates the brake pedal when you lift off the accelerator pedal. This means the battery is charged even when the brake pedal isn’t pressed. A ‘Hold’ function preserves as much as the battery as possible, saving it for later in the journey, making it useful for when your destination includes urban driving or a low-emission zone.
