Opel has indeed fulfilled its promise and created a real-life version of the independently designed Rocks e-Xtreme. The concept was originally created by design student Lukas Wenzhöfer, who shared it online shortly after the production-spec heavy quadricycle was unveiled in September 2021. The 3D model of the Rocks e-Xtreme won the #OpelDesignHack competition in December 2022, and Opel decided to bring it to life as a result. Using Wenzhöfer’s 3D model as a starting point, Opel built the Rocks e-Xtreme with several unique modifications. The vehicle retains the body of the regular-production model, but it has been heavily customized. Wenzhöfer added massive wheel arch flares, protruding alloy wheels, and an external roll cage with auxiliary lights. The rear of the Rocks e-Xtreme features a large carbon fiber wing from an Opel Vectra GTS V8 race car of the 2000s.
While the exterior modifications are extreme, the Rocks e-Xtreme’s specifications remain largely unchanged from the standard vehicle. It is powered by an electric motor drawing electricity from a 5.5-kilowatt-hour lithium-ion battery pack. It can deliver 8 horsepower to the front wheels. The vehicle has a top speed of around 28 mph and offers a maximum driving range of approximately 43 miles. It is important to note that the Rocks e-Xtreme is classified as a quadricycle and not allowed on highways in most European countries. Opel paid great attention to detail in bringing the Rocks e-Xtreme to life, utilizing 3D printing to realize the design. The modifications include all-terrain tires on protruding wheels, an overhauled suspension with increased ground clearance, a bright yellow roll-over hoop for safety, roof-mounted LEDs, sleeker LED lighting, and the carbon fiber rear wing from the Vectra GTS V8 DTM race car.
Despite the dramatic visual and chassis modifications, Opel did not mention any power upgrades over the stock Opel Rocks Electric, which is essentially a rebadged Citroën Ami. Both vehicles share the same electric motor, producing 8 horsepower and a 5.5 kWh lithium-ion battery. The Opel Rocks e-Xtreme is a one-off concept, and there are no plans for production at this time. Opel plans to showcase the Rocks e-Xtreme on a tour, allowing fans to see it in person. While the concept won’t be seen driving through historic city centers, some less extreme variants of the Ami have been released, such as the limited-edition My Ami Buggy and Fiat’s doorless, heritage-inspired Topolino, both of which share the same quadricycle platform.
