The challenges that the current green and hybrid cars face are high costs and restricted range or capacity.
To overcome these, we have here the e rx, a battery-powered electric vehicle concept. It mainly features an optional range extender that can be rented at gas stations or car dealerships. Essentially this kit contains all components inside one compact box: combustion engine, exhaust system, cooling unit, and fuel tank.
It is available in different sizes with respect to its power output and the size of the fuel tank.
The car concept focuses on a very lightweight and cost-efficient design.
This is realized by the reduction of fabricated parts.
The e rx is a 2012 red dot award: design concept winner.
