Volvo has developed a Plug-in Hybrid, Twin Engine technology and it will be offered first in the upcoming redesigned XC90 SUV.
Volvo Cars said its all-new XC90 all-wheel drive seven-seater will deliver 400 horsepower and 472 pound-feet of torque, but with carbon dioxide (CO2) emissions of around 60 g/kilometer (NEDC driving cycle).
The Swedish company said there has never been an SUV offering this level of power this cleanly.
“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 will offer a range of Drive-E engine options, all of which are said to provide a combination of performance and fuel-efficiency. The main feature of the Drive-E engine range is that they are all four-cylinder engines.
“With our new Drive-E powertrains, we have created a family of intelligent gasoline engines with power curves that give exciting drivability at the same time as delivering world-beating fuel economy,” added Dr. Mertens. “With seven people in the new XC90, carbon dioxide emissions per person are outstandingly low.”
For the all-new XC90, Volvo said the top of the range plug-in hybrid ‘Twin Engine’ will carry the badge ‘T8’ and 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 two-liter, four-cylinder supercharged and turbocharged Drive-E gasoline engine that powers the front wheels and an 80 horsepower (60 kilowatt) electric motor that drives the rear wheels.
The company explained the engine 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 25 miles, and then, when needed, immediately revert back to the combined capacity of the gasoline engine and electric motor, with its combined output of around 400 hp and 472 pound-feet of torque.
The Volvo XC90 range will also includes a T6 gasoline engine option. The T6 turbo engine with supercharger and turbo will deliver 316 horsepower and a maximum torque of 295 pound-feet. The T6 is expected by the company to offer a best-in-class combination of power and fuel economy, even when compared to diesel models.
“Since our new Scalable Product Architecture (SPA) technology is designed from the start to accommodate electrification technologies, the Twin Engine installation does not compromise luggage or passenger space,” said Dr. Mertens.
The original XC90 was launched in 2002. Volvo has not yet released fuel consumption or price information, both of which will be available closer to launch.
