The new V60 is billed by its creators as being a "naughty Volvo," and while the reviews we've read of its sedan counterpart haven't exactly found it to be particularly uncouth, we're thinking the upcoming plug-in wagon version should be even more friendly. Volvo has announced it will unveil the PHEV V60 in Geneva in March before releasing it for sale in 2012. When fully charged it will offer 50km (31 miles) on pure electricity -- about the same as the Volt -- thanks to a 70hp electric motor mounted in the rear and driving the wheels out back courtes
