The T8 Plug-in Hybrid produces 400 hp and 640 Nm of torque.

The electric motor that represents the other half of the T8 Hybrid system produces 80 hp and 240 Nm of torque at the rear axle. Power is sourced from a a high-voltage (270–400 V) battery placed in the central section of the car. According to Volvo, the positioning of the battery does not affect the amount of cabin space available while also keeping a low and central gravity for better handling. Furthermore, the battery can be recharged using the two-step brake energy recovery system.

The driver can select up to 5 modes.

The car has five different driving modes: The Hybrid mode is the default mode that automatically switches between the petrol engine and the electric motor on the basis of power requirement. The Pure Electric mode returns a range of up to 40 km in complete silence. Like today's hybrid hypercars, the Power mode combines the performance of both the combustion engine and the electric motor for quick figures, the AWD mode offers constant all-wheel drive, and finally, and the Save mode that saves energy for the Pure Electric mode.

Volvo claims that the XC90 is the "cleanest" crossover in the market, as it returns an emissions figure of 59 grams of CO2 per km, and an average fuel efficiency figure of 2.5l/100km (40 km/l).
