with a diesel engine. 2015–2020 For the 2015 model year, Ford discontinued sales of the E-Series passenger and cargo vans, replacing them with the fourth-generation Ford Transit. Because of its popularity with upfitters who convert the chassis into recreational vehicles, buses, or other specialized vehicles, Ford announced it would continue to offer the E-Series as a cutaway chassis (open cab, to be fitted with second-party rear body), a chassis cab (enclosed cab, to be fitted with second-party rear body) and a stripped chassis (no cab, to be fitted with a complete second-party body). Ford said it made the change, because while the E-Series had remained the best-selling vehicle in the full-size van segment since 1980, the model line had seen little change since 1992 on a chassis introduced for the 1975 model year. At the time of its 2008 update, 95% of sales were to commercial or fleet users, with nearly half of production represented by cargo vans.

Under the hood, all models use the larger 7.3L V8 Godzilla naturally-aspirated gasoline engine also used on Super Duty trucks. However, The exterior design remains unchanged from the 2008 redesign. The instrument cluster now has a monochromatic screen with an available upgrade to a color screen. The new instrument panel also allowed for the addition of new optional safety equipment that was previously not available on the E-Series, including adaptive cruise control, a forward collision avoidance system, a lane departure warning system and automatic high-beam front headlamps. Meanwhile, the touchscreen Ford Sync infotainment system was eliminated. The only available factory audio system is a
