1977 – “The fence engine”


Engine history was being made across a garden fence in Långedrag in Göteborg. Lars Malmros of the Volvo Truck Corporation and Harald Wiklund of Volvo Penta were neighbors and they agreed that what was missing from their joint product program was a small six-cylinder diesel engine. Together they decided to solve this and the concept for the 40 engine, otherwise known as the “fence engine”, was created. A plant for the production of the 40 engine was built in Vara, Sweden and, at the introduction in 1977, an enthusiastic trade press wrote that this was “the first engine that combined the acceleration ability and quiet running of the gasoline engine with the economy and reliability of the diesel”.
