Volvo Cars’ all-new XC90 SUV, to be launched later this year, will offer up to 400 horsepower (298 kW) but with CO2 emissions as low as around 60 g/km (NEDC driving cycle). The new XC90 will offer a range of Drive-E engine options, all of which are 4-cylinder engines. (Earlier post.)
For the all-new XC90 seven-seater, the top of the range “Twin Engine” will be a plug-in hybrid (PHEV) and carry a T8 badge. Normal driving is conducted in the default hybrid mode. This utilizes a two-litre, four-cylinder supercharged and turbocharged Drive-E gasoline engine that powers the front wheels and an 80 hp (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.
The driver can switch to pure electric power where the range will be around 40 kilometers (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 640 N·m (472 lb-ft) of torque.
The Volvo XC90 range also includes the D5 twin turbo diesel engine with 225 hp (168 kW), 470 N·m (347 lb-ft), fuel consumption of around 6 l/100 km (39 mpg US) and the D4 turbo diesel engine with 190 hp (142 kW), 400 N·m (295 lb-ft) and fuel consumption of around 5 l/100 km (47 mpg US).
The range also offers two gasoline engine options. The first is a T6 turbo engine with supercharger and turbo with 320 hp (239 kW) and a maximum torque of 400 N·m. The second is a T5 with 254 hp (189 kW) and 350 N·m (258 lb-ft).
Volvo Cars’ new Scalable Product Architecture (SPA) chassis technology also allows for far more flexibility inside the car. (Earlier post.)

Volvo launched the original XC90 in 2002. The new XC90 is the first Volvo to use the company’s Scalable Product Architecture (SPA).
