Lots of electric juice lately, right? Well it's Tokyo show and back in January with the Volt presentation at Detroit show we already predicted that Tokyo would be the most interesting show of the year for electric vehicles and/or plug-in hybrids. And of course it turned out true with lots of concepts although no vehicles for sale, yet. The picture below shows the Toyota 1/X concept, a plug-in hybrid with a very small 500cc IC engine that moves the car because it is very light: 420kg only! However, the amount of carbon fibre used in the vehicle does not point to a future series production due to cost issues, even if (finally!) reducing weight is a new trend in the industry.
