Volvo has seen the future and is going full speed ahead with the latest hybrid technology. As a potential second plug-in-hybrid offering, Volvo has announced it will unveil the XC60 Plug-in Hybrid Concept at the 2012 North American International Auto Show in Detroit next week.

Just like the Volvo V60 plug-in-hybrid (PIH), the production intended XC60 concept is an all-in-one electric, hybrid and performance car by utilizing the gasoline engine or electric motor separately or together for full power. The three modes of operation (Pure, Hybrid or Power) are selected by the touch of a button. However, the biggest difference between both PIHs is that the combustion engine in the V60 is diesel while the XC60 concept is gasoline.

In Pure mode the car has a range of 35 miles (56 km) using the U.S certification driving cycle while 45 km (27 mi) is achieved according to the European certification driving cycle NEDC.

Hybrid mode is the standard setting and uses the gasoline engine and electric motor together. In this mode as measured by the NEDC method, emissions are 53g/km while fuel consumption is a segment busting low of 2.3l/100km (123 mpg UK / 102 mpg US). Using the U.S certification driving cycle for a high-efficiency hybrid, the combined fuel economy in continuous driving is 50 mpg. The XC60 concept has a total range of up to 600 mi (960 km).

In Power mode the diesel engine and electric motor are optimized to produce a combined power output of 280 PS (206 kW / 276 hp) + 70 PS (51 kW / 69 hp) and maximum torque of 380 Nm (280 lb-ft) + 200 Nm (149 lb-ft) respectively, rendering a 0 to 60 mph time of 5.8 seconds while 0-100 km/h takes a very impressive 6.1 seconds.

In essence, the XC60 concept is an SUV that performs like it has a V8 engine with a combined output of 350 PS (257 kW / 345 hp) while greatly surpassing the fuel economy of a 3-cylinder sub-compact vehicle.

Power is provided to the front wheels by a newly designed four-cylinder 2.0-liter turbo engine from the forthcoming VEA (Volvo Environmental Architecture) engine family. Motivating the rear wheels, the electric motor is powered by a 12 kWh lithium-ion compact battery pack installed under the floor of the loading compartment. Recharging takes just 3.5 hours via 220V/12A outlet while a 110V/12A full charge takes 7.5 hours.

Via a newly developed eight-speed automatic transmission, both power plants can engage in electronically controlled four-wheel drive via the AWD button. However, since power to the rear wheels is dependent on battery power, the AWD system is considered more of an occassional feature to be used in slippery conditions as opposed to a conventional permanent four-wheel drive system.

While the Volvo V60 PIH is only planned for Europe, the XC60 PIH is intended for North America and China.

"This world-class gasoline plug-in hybrid technology, featuring a state-of-the-art four-cylinder engine from our upcoming Volvo Environmental Architecture engine family, will reach our American showrooms in a couple of years. However, it is too early to say which model will be the first to feature this solution," according to Stefan Jacoby, President and CEO of Volvo Car Corporation.
