Volvo XC90 T8 Twin Engine range, MPG, CO2 & charging

The Volvo XC90 T8 offers useable electric range and therefore strong efficiency. Charging is simple, too.

A large, premium seven-seat SUV like the Volvo XC90 T8 is a great plug-in choice, as it gets around the disadvantages of a car like this when it comes to efficiency, combining petrol and electric power to serve up strong fuel economy and low CO2.

Charging is easy – just remember you’ll have to do it every day to get the best from the car. You'll get 20 miles of pure-electric running very easily in varied real-world driving, or up to 25 miles in slower stuff, which is competitive by most PHEV standards, but the BMW X5 plug-in does go usefully further. 

Volvo XC90 T8 range

With a full battery, the XC90 T8 will cover up to 28 miles on electric power alone by official standards, but in reality you'll see more like 20-25 miles depending on the sort of driving that you do. Around town you'll see the Volvo go further than if you're on the motorway regularly. However, this isn’t exactly realistic. If you're keen to save fuel and money, you need to make sure that you can plug the XC90 in regularly at home, at work, or ideally both.

Charge time

As we’ve already mentioned, the XC90 T8 comes with a 4.5-metre long three-pin cable as standard, while a 4.5-metre Type 2 cable for a faster charger or wallbox is a £50 extra, which jars when you’re paying upwards of £65,000 – especially when it’s needed to make the most of the car's sophisticated powertrain and the efficiency potential.

Recharge times depend on the power supply you’re plugged into. A three-pin domestic socket will charge the battery up in six hours. This is cut to four hours for a 3.6kW supply, while you’ll only need two and a half when hooked up to a faster 7kW feed.

Provided you add the optional £50 Type 2 charging cable, the Volvo is compatible with any Type 2 AC charger (which are very common in towns as well as on motorways), but it's limited to a maximum charge speed of 7kW, so it'll take 2.5 hours to charge at best regardless of how powerful the feed you plug into is. The XC90 T8 is not compatible with DC fast chargers. 

There’s also a driving mode that uses the petrol engine to charge the battery on the move. It’s useful if you want to top the battery up to use for all-electric driving when you get to a town, but it does place more strain on the engine, so expect your fuel economy to dip in this mode. A battery hold function is also a feature, so you can use the petrol engine to get you down the motorway and save your electric mileage for when you get into the city.

Battery warranty

Every T8 Twin Engine model in Volvo’s line-up gets an eight-year/100,000-mile warranty that covers the battery. This means if the battery starts to deteriorate beyond set levels, then you’ll get a new one, free of charge. However, we don’t expect this to happen.
