Volvo has shed more light this week on its big new XC90 SUV’s powertrain line-up, including the new ‘T8 Twin Engine’ system.
Sitting at the top of the exclusively four-cylinder XC90 line-up, the T8 pairs a turbo- and supercharged 2.0 litre Drive-E petrol engine with a 60kW electric motor.
With the petrol engine motivating the front wheels and the electric motor sending power to the rear, the T8’s plug-in hybrid system will offer a combined 298kW and 640Nm of torque.
Volvo says that the engine’s supercharger will work at the bottom end of the rev range to create the impression of a powerful naturally-aspirated engine, with the turbocharger coming online as airflow builds up.
The rear wheels benefit from the immediate torque inherent with electric motors, and drivers will have the ability to drive either on electric power alone - for around 40 kilometres - or switch back to petrol-electric driving.
As a plug-in hybrid, the T8 also keeps carbon emissions low - around 60g/km.
Importantly, the design of Volvo’s Scalable Platform Architecture (SPA) already incorporated plans for electrification, meaning that the hybrid system in the T8 will not compromise passenger or storage space.
Diesel And Petrol Engines Also Coming
The XC90’s four-cylinder Drive-E engine range will also include ‘conventional’ diesel and petrol options, focused on both power and efficiency.
Diesels will include the 168kW/450Nm twin-turbo D5 that lists fuel consumption at just 6.0 l/100km, while the less powerful but even more frugal 142kW/400Nm D4 drops fuel use to 5.0 l/100km.
On the petrol side will sit the 189kW/350Nm T5, followed by the turbo- and supercharged T6 with 238kW and 400Nm.
“With our new Drive-E powertrains, we have created a family of intelligent petrol and diesel engines with power curves that give exciting driveability at the same time as delivering world-beating fuel economy,” Volvo’s Peter Mertens said.
“With seven people in the new XC90, carbon dioxide emissions per person and kilometre are outstandingly low.”
Volvo’s new XC90 will make its global debut at the Paris Motor Show in October, with an Australian debut likely to occur in the first half of 2015.
