The car manufacturer, Ford, has developed an innovative new process, called Plasma Transferred Wire Arc coating technology, which applies a spray to the inside of a worn-out engine block to return it to its original factory condition. According to Ford, by giving old engines that would otherwise be scrapped a new lease of life, CO2 emissions are reduced by 50%.

Juergen Wesemann, Manager of Vehicle Technologies at Ford's advanced engineering department, said "we have taken a process that was originally developed to enhance performance models such as the all-new Ford Mustang Shelby GT 350R and used it to remanufacture engines that might otherwise be scrapped." He said that this was one of a number of innovative measures that Ford was taking to lower its environmental footprint.
