The next step for Opel was the resumption of passenger car production. It might have seemed easiest to bring back the Kapitän first since its engine was already in production for the truck, but occupation regulations restricted German civilians to cars of 1.5 L or less, which made the Olympia the obvious candidate. Under Dr Ing e.h. Karl Stief, who had been chief engineer at Opel since 1934, useful changes were made to this tough little car. The Dubonnet front suspension was replaced by a conventional coil-and-wishbone layout and the steering was correspondingly rearranged.
Opel operates 10 vehicle, powertrain, and component plants and four development and test centres in six countries, and employs around 30,000 people in Europe. The brand sells vehicles in more than 60 markets worldwide. Other plants are in Eisenach and Kaiserslautern, Germany; Szentgotthárd, Hungary; Zaragoza, Spain; Gliwice, and Tychy, Poland; Aspern, Austria; Ellesmere Port, and Luton, Great Britain. The Dudenhofen Test Center is located near the company's headquarters and is responsible for all technical testing and vehicle validations.
Clever design tweaks set the KARL ROCKS apart from most of its A-segment rivals. The functional silver roof rails, rugged front and rear bumpers with integrated skid pads, front and rear wheelhouse moldings and unique 15-inch bi-color-look alloy wheels blend in perfectly with typical Opel design cues such as the Opel blade that sweeps dynamically up towards the rear. Combined with the sloping roofline this creates a dynamic, sporty appearance that links the KARL ROCKS to the KARL while simultaneously giving it a distinct rugged look.
Instead, it had the same front fascia as the Latin American Chevrolet Corsa, possibly because GM South Africa wanted the same front fascia as the sedan and pickup, as swapping with the European front fascia would have been expensive sawing and welding due to the Latin American Corsa's sharper headlights. This car was 2001 Semperit Irish Car of the Year in Ireland.
