Volvo’s new XC90 will be the world’s most powerful and cleanest SUV

Volvo’s new XC90 will offer an unrivalled combination of power and clean operation when it is launched later this year. The all-wheel drive seven-seater offers up to 405ps, but with CO2 emissions of around 60 g/km (NEDC driving cycle).

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

The new XC90 offers a range of Drive-E engine options, all of which have four cylinders, and provide both performance and fuel-efficiency.

“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,” adds Mertens. “With seven people in the new XC90, carbon dioxide emissions per person and kilometer are outstandingly low."

Volvo has made it possible for a four-cylinder engine to provide all the driving pleasure associated with a much larger engine and do so far more efficiently and cleanly. Drive-E engines will over time be introduced across Volvo’s entire range.

For the XC90, the top of the range Twin Engine will carry the T8 badge, and will be a plug-in electric car, hybrid car and high-performance car rolled into one.

Normal driving is conducted in the default hybrid mode. This utilizes a 2-liter, four-cylinder supercharged and turbocharged Drive-E petrol engine that powers the front wheels and an 81ps (60 kW) electric motor that drives the rear wheels.

It uses the supercharger to fill in the bottom end of the power range to give the engine a big, naturally-aspirated feel, while the turbocharger kicks in when the airflow builds up. The electric motor on the rear wheels provides immediate torque.

But at the push of a button the driver can switch to quiet and emission-free city driving on pure electric power where the range will be around 40km, and then, when needed, immediately revert back to the combined capacity of the petrol engine and electric motor, with its combined output of around 405ps and 640Nm of torque.

The XC90 range also includes the D5 twin turbo diesel engine with 228ps, 470Nm, best in class fuel consumption of around 6l/100 km and the D4 turbo diesel engine with 192ps, 400Nm and a fuel consumption of around 5l/100 km.

The range also offers two petrol engine options. The first is a T6 turbo engine with supercharger and turbo with 324ps and a maximum torque of 400Nm. The second is a T5 with 258ps and 350Nm.

Volvo' new Scalable Product Architecture (SPA) chassis technology allows for far more flexibility inside the car. Other carmakers have struggled to combine the bulk of a battery pack with a luxurious and spacious interior, something that Volvo has managed to overcome.

“Since our new SPA technology is designed from the start to accommodate electrification technologies, the Twin Engine installation does not compromise luggage or passenger space,” says Mertens.
