Gasoline direct injection (GDI) has existed for over 100 years. Since its introduction into the automotive industry in the early 1950's, GDI has had an off-and-on relationship with cars and trucks. Today, it looks like GDI is here to stay. With more and more manufacturers including GDI across their entire fleet of vehicles, we've seen massive strides in vehicle performance and efficiency. Combine those improvements in GDI with the increasing popularity of turbocharging and we're living in a time where small four- and six-cylinder engines are making more power than their eight-cylinder ancestors, all while using less fuel than some of the smallest engines of the past 50 years.
No technology is without its downfalls, however. GDI has come a long way in 50 years, with most of that innovation coming in the last 20 years. Like all technology, the exponential
