Ford now sells an electric car and some plug-in hybrids, but you don't hear all that much about them. They're just a few drops in an ocean of gasoline EcoBoost engines.

Meanwhile, Ford recently built its two-millionth EcoBoost engine, a 2.0-liter four-cylinder destined for an Escape crossover utility vehicle.

Launched in 2009, the EcoBoost line of engines was intended to replace larger-displacement naturally aspirated gasoline engines.

And while Ford's hybrid sales have soared this year, the company has sold only 277,400 hybrids, including 8,500 plug-in hybrids--plus exactly 1,918 battery-electric vehicles--from October 2004 through last month.

The 2 million EcoBoost engines all use turbocharging, direct injection, and other refinements to produce the power of a larger engine while their smaller displacement is intended to provide better fuel economy.

Ford currently offers 1.5-liter, 1.6-liter and 2.0-liter EcoBoost four-cylinder engines, as well as a 3.5-liter V-6.

The engines are offered in most of Ford's mainstream models, including the Focus, Fusion, and Taurus sedans and the Escape, Explorer, and Flex crossovers, plus several Lincoln models.

Three performance models, the Fiesta ST, Focus ST, and Taurus SHO, also feature EcoBoost engines.

And Ford puts the EcoBoost V-6 in the F-150 pickup truck, although that truck gets the lowest rating of the three major 2014 pickup trucks fitted with their most fuel-efficient engines.

According to Ford, 90 percent of Escape models now have EcoBoost engines, along with 50 percent of Fusion sedans, and 42 percent of F-150 trucks.

Even the cops use them: Police versions of the Taurus and Explorer use the same engines as their civilian counterparts.

A 1.0-liter, three-cylinder EcoBoost engine will also be available on the 2014 Fiesta.

EcoBoost may seem like the best of both worlds, but Ford's fuel economy claims haven't necessarily always held up in the real world.

An Escape equipped with the 2.0-liter EcoBoost engine only returned 22 mpg in a Consumer Reports test, the same as a 3.5-liter V-6 2013 Toyota RAV4--and lower than its EPA combined rating of 25 mpg.

Whether small turbocharged engines really get better gas mileage is still up for debate.

And Ford continues to offer a number of non-turbo engines, unlike Volkswagen's plan to offer only turbo engines--both gasoline and diesel--in its U.S. lineup by 2015.
