History of the diesel car featured an aluminium block, DOHC chain driven valvetrain, common rail direct injection and variable geometry turbocharger. In Spring 2005, Mercedes-Benz unveiled their first application of a mass-produced aluminum block diesel engine for passenger vehicles and commercial use. While aluminum is traditionally considered of inferior strength and temperature resistance to withstand diesel applications, Mercedes engineers made extensive use of CAD/CAM design to arrive at an aluminum block that would meet with Mercedes' testing and reliability standards. First use was in 2006 model-year vehicles in the E-Class sedan and ML-class and GL-class SUVs. Similar in weight () to the five-cylinder it replaced,

As they have aged in car applications, they have developed a reputation for blowing head gaskets, due to the separate cylinder head design. In 1997, the first common rail diesel passenger car was introduced, the Alfa Romeo 156. In 1998, for the very first time in the history of racing, in the legendary 24 Hours Nürburgring race, a diesel-powered car was the
