The fuel-economy champ in the 2014 Ford Taurus line is the 2.0-liter EcoBoost four-cylinder turbocharged engine, at a combined 26 mpg rating (22 mpg city, 32 mpg highway). That's not bad, but it's a far cry from the real-world 40 mpg we saw in the Avalon Hybrid that's Toyota's new and stylish large sedan competitor--and lower than the 29-mpg combined rating of the Buick LaCrosse with eAssist.
Otherwise, the 3.5-liter V-6 models come in at 23 mpg combined (19 mpg city, 29 mpg highway) in front-wheel-drive form. Adding all-wheel drive (available on SEL and Limited models) bumps that down to 21 mpg combined (18 mpg city, only 26 mpg highway). We saw almost 20 mpg in a Taurus Limited AWD test car over more than 250 miles of driving.
The hot-rod Taurus SHO model with the turbocharged 3.5-liter engine does even worse, at just 20 mpg combined (17 mpg city, 25 mpg highway), but the SHO we drove enthusiastically for more than 100 miles returned just 16.5 mpg.
