The word

The EcoBoost I-4 engine is a 2.0L, four cylinder engine putting out power equivalent to a V6. It is EPA rated at 14mpg city/20mpg highway (16mpg combined) in the new Explorer.
That is a 30% efficiency improvement over the 2010 model. Other changes include a new body design, lighter weight, and better materials in the new Explorer.
Many engine components have been swapped for electric versions, such as the power steering assist and a faster engine warmup system.
And so ...
While still not the best, at least the SUV is getting better. This model also debuts a variable-displacement air conditioning compressor to the U.S.
