The slow trickle of information regarding the upcoming Volvo XC90 continues ahead of its debut next month, with the company releasing details about the seven-seater SUV's powertrains. Headlining the engine lineup will be a plug-in hybrid that Volvo says will make the XC90 the "most powerful and cleanest SUV."

The hybrid will wear "T8" and "Twin Engine" badges and features a 2.0 litre supercharged and turbocharged Drive-E four-cylinder petrol engine powering the front wheels and an 60 kW (80 hp) electric motor driving the rear wheels. Together, the tag team will develop around 400 hp and 640 Nm and will be capable of an all-electric range of around 40 km as well as carbon dioxide emissions of around 80 grams per kilometre.

"There are no compromises when you drive an all-new XC90," said Volvo senior vice president of research and development, Peter Mertens. "In the past you could either have power or low CO2 emissions. But with the all-new XC90 you can have both."

Volvo also says that its new Scalable Product Architecture (SPA) was built to be far more flexible than before and was designed to accommodate electrification technologies from the start, allowing the T8 hybrid to pack a large enough battery pack without compromising on passenger or luggage space.

Elsewhere in the range, there will also be D5 twin-turbo diesel engine that promises 225 hp, 470 Nm and fuel consumption of around 6.0 litres per 100 km (the latter of which Volvo claims is best-in-class) and a D4 turbodiesel developing 190 hp and 400 Nm and consuming around 5.0 litres of fuel per 100 km. Also on offer will be a T6 supercharged petrol mill that will produce 316 hp and 400 Nm.
