In May 1980, Bo Nyhlén succeeded Ernst Knappe at the helm and in 1982 AB Volvo Penta became an independent company within the Volvo Group. For the first time turnover exceeded one billion kronor and in 1981 sales rose by 16 per cent. The success of the industrial engines continued and accounted for one-third of the turnover at the start of the 1980s. The marine sector was still trying to tackle the problems caused by the oil crises of the 1970s but the introduction of the Duoprop brought new success and the parts business started to improve at the same time.
A new production plant was opened in Göteborg, the main office area in Göteborg re-equipped and extended, new testing chambers added, new facilities built at the Test Center Krossholmen, EDP developed constantly and a new organisation established to make Volvo Penta increasingly efficient. 1988 Jan Walldorf became the President of Volvo Penta.
