Big changes are coming in the full-size sedan category. And with EPA fuel economy numbers now in for the 2013 Ford Taurus with the base 2.0-liter EcoBoost four-cylinder engine, certified at 32 mpg highway, 26 mpg combined, the race is on.Without a hybrid system, Ford is delivering some pretty impressive mileage with a combination of direct injection, turbocharging, and twin independent variable camshaft timing (Ti-VCT) in its 2.0-liter EcoBoost four-cylinder engine. In short, the engine gets 25 more horsepower, a 1 mpg increase in city fuel economy and a 2 mpg boost on the highway, when compared to the previous Taurus base V-6.
There’s still the Taurus SHO, with a 3.5-liter EcoBoost V-6 for those who just have to have 365 horsepower, and it still manages to deliver 25 mpg on the highway.
How does the Taurus EcoBoost stack up with some of its full-size competition, as well as some mid-size sedans?

In its first full redesign in nearly a decade, the 2014 Chevrolet Impala will arrive in dealer showrooms sometime next year boasting, among other impressive attributes, three new powertrains. Instead of the V-6 and V-8 engines of years past, GM is putting four-cylinder engines under the hood to boost fuel efficiency. The base models will have a 195-horsepower 2.5-liter four-cylinder engine paired with a six-speed automatic transmission. In addition, there’s also an Impala with a version of the GM eAssist technology also found in the Buick LaCrosse and Regal and Chevy Malibu. In the 2014 Impala, this setup is anticipated to return a 35-mpg highway rating.
