Volvo’s latest concept will be unveiled in Detroit next week, but won’t hit US showrooms for a couple of years. Last month we revealed official specs of the diesel-electric V60 plug-in hybrid that Volvo plans to release for the European market, and now we gt to preview the gasoline-electric version that’s coming to the US. The XC 60 concept will be unveiled at Detroit next week, and just like the V60 it’s an all-in-one electric, hybrid, and performance car that utilizes its combustion engine and electric motor in unison or individually depending on the driver’s needs. At the touch of a button, the car can switch from Pure to Hybrid to Power mode, however where the V60 is diesel, the XC60 concept is gasoline. In Pure mode the car has a 35-mile range powered purely by its electric motor, which is rated at 69hp and 149lb-ft of torque and drives the rear axle. It’s powered by a 12kWh lithium-ion battery sitting under the floor of the loading compartment, which takes 7.5 hours to charge via regular household power outlet and 3 hours via a 220V supply, and can also be topped up using brake energy regeneration technology. In Hybrid mode, the concept’s standard setting, the new-generation 2.0-liter turbo four engine, rated at 276hp and 280lb-ft, and the electric motor combine to boost range, working in sync or alternating as required. As per standard parallel hybrids, the electric motor kicks in for stop-and-go traffic, while the gas engine takes charge during heavy acceleration and high speed driving. The combined fuel economy in continuous driving is 50mpg and the concept has a total range of up to 600 miles. Finally in power mode the two power sources are optimized to deliver a maximum output of 345hp and maximum torque of 429lb-ft. The vehicle can then accelerate from 0-60mph in 5.8 seconds while benefiting from an all-wheel drive set up. Both powerplants can engage in electronically-controlled four-wheel drive using the AWD button with power sent to the wheels via a newly developed eight-speed automatic transmission. This is really more of an occasional feature for slippery conditions as opposed to a permanent 4WD system as power to the rear wheels is dependent on battery power.
