In the late 1970s and early 1980s, Renault increased its involvement in motorsport, with novel inventions such as turbochargers in its Formula One cars. Renault's Head of Engines, Georges Douin, orchestrated the installation of turbocharged engines across much of the Renault range beginning in 1980. 10% of all turbocharged European cars in 1984 were Renaults. The company's road car designs were revolutionary in other ways also – the Renault Espace was one of the first minivans and was to remain the most well-known minivan in Europe for the next two decades. The second-generation Renault 5, the European Car of the Year-winning Renault 9, and the most luxurious Renault yet, the aerodynamic 25, were all released in the early 1980s. At the same time, poor product quality damaged the brand. The ill-fated Renault 14 may have been the culmination of these problems in the early 1980s.
