As the F-150 EcoBoost sales pass 400,000 units since its launch in America in 2011, Ford decided to share some facts and figures about on the vehicle with us. They claim that Ford F-150 EcoBoost owners collectively are saving an estimated 45 million gallons of gas annually.

That is more than Toyota and Tesla plug-in hybrids and electric vehicles manage to save. Estimated fuel savings are based on the EPA-estimated combined ratings for 2011-13 F-150 EcoBoost models and for the same mix of 5.4-liter V8-equipped 2010 F-150 models, across 400,000 units and 15,000 miles of driving a year.

Mind you, that doesn’t mean these trucks are very economical. They are just more efficient than non-EcoBoost equivalents. In terms of fuel economy, the 4×4 version of the F-150 have EPA-estimated ratings of 15 mpg city and 17 mpg combined, and the 4×2 models manage 16 mpg city and 18 mpg combined.

These are still impressive numbers considering the versatility of the F-150 trucks, their towing and hauling capabilities. No wonder then the sales numbers have been constantly growing in recent years. F-150EcoBoost helped F-Series surpass 60,000 sales in October, the sixth-straight month it achieved this milestone – and the first time since the period of April through September 2006. There are more interesting pickup truck sin the market, but none of them delivers the same complete package as the F-150 EcoBoost.
