Ford's group vice president of global product development recently downplayed the possibility of a F-150 diesel but that could soon be changing.
According to The Truth About Cars, the success of the Ram 1500 EcoDiesel has pushed Ford to develop a new 3.0-liter V6 diesel engine codenamed "Lion." There's no word on specifications but it is expected to be offered in the F-150 by 2018.
Around this time, we can also expect to see the next-generation Ford Expedition and Lincoln Navigator. Little is known about the models but they are expected to feature aluminum bodies and a a ten-speed automatic transmission.
Interestingly, the report says the next-generation F-Series Heavy Duty will eschew the weight saving aluminum and use steel compoents instead.
