In the US, the 1968 Kadett took on the Olympia’s grille and there were other changes too. The Olympia and the US Kadett now were available with the bigger “high-cam” four, in 1.5, 1.7 and 1.9 liter versions (no 1.7 for the US). This changed the performance equation considerably, especially in the new Rally 1900, which had a new fastback to go along with its big jump in power. The 1.9 was rated at 102 (gross) and 90 (DIN-net) hp, and there was nothing that could touch it in its class. This was the equivalent of dropping the big block V8s in the GM midsize cars, the German Chevelle SS 396.
With these guidelines in mind, the Opel question was put again on 3 May to the GM financial policy committee, which then withdrew its objections to a return to Rüsselsheim. Many details still had to be worked out, both within GM and in the US-occupied zone of Germany, before this could actually occur. At last, the official word was released on 1 November 1948; GM resumed management control of Adam Opel AG. Edward W. Zdunek, formerly regional manager for Europe of General Motors Overseas Operations Division, was named managing director.
After seven years, 238,647 Calibras had been produced at the main plant in Rüsselsheim, and also at Valmet in Uusikaupunki, Finland. The Calibra’s biggest markets were Germany, the UK, Italy, Spain and France. The 115 hp entry-level model led the sales charts with production totaling more than 130,000 units, followed by the 150 hp, 2.0-liter version, of which more than 61,000 were built.
In 1924, the Rüsselsheim-based company went even further to cater to the “average consumer” – also thanks to an automotive innovation. After all, from the very first minute Opel was committed to producing cars as efficiently as possible and thus making them affordable for a broad customer base. Consequently, the 4/12 hp heralded the start of assembly line production in Germany. And because the 60 km/h fast car was only available “in a quiet green that pleases the eye” to keep the time and effort required for production at a minimum, everyone called it the “Tree Frog”. Soon, 25 two-seater “cars for everyone” left the assembly line every day. In the following years an entire vehicle family was built on the Tree Frog technology. The smoother production ran, the greater the cost advantage that Opel passed on to its customers. Unbelievable but true: the purchase price of the 4 hp model series, of which 119,484 units were produced, was almost 40 per cent lower in 1931 than at the launch of the Tree Frog model.

Rüsselsheim. In 2019 Opel celebrates 120 years of automobile production – and thereby 120 years full of innovations for everyone. The German brand has a tradition of pioneering high-tech advancements and quickly bringing them to series production. This makes mobility affordable for many and the cars safer, cleaner, more comfortable and more practical. The 120 years advertising campaign, “Opel. Born in Germany. Made for everyone.” is based on this philosophy. It was as true of the first Opel – the Patentmotorwagen “System Lutzmann” of 1899 – as of all the other models that followed, from the “Doktorwagen” to “Laubfrosch” (Tree Frog), P4 and Kadett. Today the philosophy matches the Opel Corsa more than any other model.
