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,
Diesel Electric railmotor (VR) Diesel Electric railmotor (VR) The Diesel Electric Rail Motor (DERM) was a railmotor operated by the Victorian Railways of Australia. Originally built as a Petrol Electric Rail Motor (PERM), they were the longest-lived railmotor on the Victorian Railways, with the first entering service in 1928 and the last being withdrawn in 1991. The first was built by the Newport Workshops to a design of the St. Louis Car Company. They were powered by Winton Motor Carriage Company petrol engines, until those were replaced in the 1950s by twin Diesel Electric engines providing a power output of . A DERM, with
