Ford plans not only to double production volume of four-cylinder engines but also to offer a four-cylinder in every one of its cars and crossovers by 2013. Helping make that plan a reality is Ford's EcoBoost system, which combines direct injection and turbocharging to yield an engine with small displacement yet big power.

Impressive economy figures should roll in with EcoBoost four-cylinders; larger units will replace current V-6s, and fuel-stingy small fours will replace current large fours. Ford is mum on when we'll see the first four-cylinder EcoBoost for sale, but does say that they will make up about two-thirds of total EcoBoost volume. Industry analysts predict we'll first see this new family of efficient fours in the Focus line, with the Fusion to follow shortly thereafter.
EcoBoost debuts this summer in the 3.5-liter V-6 that will power uplevel versions of the 2010 Ford Taurus, the Ford Flex, and the Lincoln MKS. Hardly ultra-frugal, Ford promises V-8 power with V-6 economy in this application (currently, the Flex manages 17/24 with its 3.5-liter non EcoBoost V-6), a respectable if not amazing start for the EcoBoost program.
