Opel has revealed the one-off Rocks e-XTREME electric buggy as a next-level all-electric urban mobility solution. The German carmaker kept its promise to design student Lukas Wenzhofer by building a real-life example of his original renderings from the "Rocks-e Design Hack" competition. The unique-looking EV is based on the Rocks-e model, which itself draws inspiration from the quirky city roundabout, the Citroen AMI.
