Gasoline Direct Injection (GDI) is an engine technology that improves fuel economy and engine performance by injecting fuel directly into the combustion chamber, allowing for a more complete and efficient use of fuel compared to standard fuel injection. Both cars and light trucks have seen increased use of GDI in recent years as manufacturers strive to increase fuel economy while meeting consumer expectations for performance. Cars have seen the greatest increase in the use of GDI from just 0.3% market share in 2007 to 30.4% of all new cars sold in 2012.
