Ford’s “family” of modular engines is designed to streamline production, enabling one plant to produce multiple engines. This family of single- and double-overhead cam engines includes 4.6 and 5.4 liter V8 powerplants as well the 6.8 liter V10, and it has been used in vehicles from pickup trucks to Jaguar luxury sedans.
The largest engine in the series is the 6.8 liter V10, which was used in Ford’s Super Duty heavy-duty pickups from 2003 until 2010. It also appeared in the Econoline heavy-duty vans and was used in Ford’s medium-duty truck chassis. As a result, it can be found powering many RVs and buses. A 6.2 liter gasoline V8 replaces the V10 in 2011.
