"Compared with the current cost of diesel and hybrid technologies, customers in North America can expect to recoup their initial investment in a 4-cylinder EcoBoost engine through fuel savings in approximately 30 months. A diesel in North America will take an average of seven and a half years, while the cost of a hybrid will take nearly 12 years to recoup - given equivalent miles driven per year and fuel costs."
Derrick Kuzak, Ford’s group vice president of Global Product Development
