With a new six-speed transmission in gear, the 2011 Hyundai Azera's fuel economy has improved by anywhere from 5 to 10 percent, bringing it close to the top of the full-size sedan segment.
The EPA rates the 2011 Azera with the smaller 3.3-liter V-6 at 20/28 mpg. That's just one mile per gallon less on the highway cycle than the 2011 Toyota Avalon, which leads the class. (The slightly smaller Buick LaCrosse is rated at 19/30 mpg in four-cylinder trim.)
With its larger 3.8-liter V-6, the Azera earns a 19/27 mpg rating, which brings it ahead of entries like the Ford Taurus, Chrysler 300, and Buick Lucerne--and so long as we're counting, the Porsche Panamera.Hyundai hasn't said whether it will introduce a hybrid Azera, but the model will be replaced in the 2012 model year.
