We’re pretty sure by now you’ve heard of the phrase ‘range-anxiety’ – its a term to define the anxiety caused when your electric car ‘distance to empty’ figure reads something below 5 miles.

Swiss firm Rinspeed is now trying to address the range anxiety issue with an innovative Dock+Go concept that it will show at the 2012 Geneva Motor Show.

The Smart ForTwo Electric Drive based concept comes with a detachable trailer, which Rinspeed calls a ‘backpack on wheels.’ The dock houses a combustion engine or a range extender that will be packed with batteries or powered by a fuel cell. The pack increases the overall range for the ForTwo Electric Drive.

Any battery packs can be recharged using solar panels on the roof.
