Ford 1.0L EcoBoost 3-Cylinder: Autoblog Technology of the Year award finalist

Wed, 19 Nov 2014

As the old saying goes, "There's no replacement for displacement." But these days, many automakers are launching powerful, downsized engines that offer similar or better power output than their predecessors, all while offering improvements in fuel economy and emissions. These days, we're seeing automakers replacing eight-cylinder engines with turbocharged sixes, and the naturally aspirated six-cylinder motors are being phased out in favor of potent turbo fours. But Ford has gone even smaller, offering a three-cylinder, turbocharged engine with one single liter of displacement.

Sure, three-cylinder engines aren't anything new – they've been offered around the globe for ages. But Ford's EcoBoost 1.0L powerplant is perhaps the best application the Autoblog team has tested. Gone are the triple-cylinder complaints of yore – this engine doesn't sound anemic or buzzy, and there's healthy power output on tap. In fact, compared to the 1.6-liter inline-four that Ford also offers in the Fiesta, the 1.0-liter is more powerful, while boasting an impressive 45 miles per gallon on the highway.

This engine has already received numerous accolades, including winning the International Engine of the Year award in 2012, 2013 and 2014. The 1.0L EcoBoost will be available in the refreshed 2015 Ford Focus here in the US.

Engine downsizing is a technique that's spreading like wildfire within the auto industry. Ford's turbo-triple proves that it can be an effective and enjoyable strategy, even on the smallest of scales.
