Official: 2014 Mazda6 with i-ELOOP most fuel efficient midsize sedan, $32,570
The 2014 Mazda6 is the Japanese automaker's new, redesigned, midsize sedan featuring Skyactiv technology, and Mazda has just released pricing for models that will be equipped with i-ELOOP. An entry-level 2014 Mazda6 starts at $21,785 after delivery, when paired with the standard six-speed manual transmission. All models feature the same 2.5-liter four-cylinder engine, capable of producing 184 hp. And the entry level Mazda6 model gets an EPA estimated 25 mpg city and 37 mpg on the highway. Add the six-speed automatic transmission and fuel economy goes up one mpg on both figures, to 26/38. That is very similar to the Nissan Altima, rated at 27 mpg city and 38 mpg highway. So how do you get a Mazda6 that gets 28 mpg city and 40 mpg on the highway? That model uses the i-ELOOP system to help dial up efficiency to best-in-class. I-ELOOP is short for "Intelligent Energy Loop," a system that essentially recycles excess kinetic energy that would normally be wasted. Using a capacitor, the system harnesses and funnels energy during deceleration, that otherwise would be lost. The i-ELOOP can use the excess energy to power some of the electrical components such as the headlights, radio, and climate control. But to get i-ELOOP, you need to spring for the 2014 Mazda6 Grand Touring model with an automatic transmission and additional GT Technology package. As such you'll pay $32,570, but you'll also get one very loaded sedan: HID headlights; 19-inch wheels; a 5.8-inch touchscreen with navigation; moonroof; and leather seats. And that price includes the $2,080 GT Tech Package that adds adaptive cruise control, high beam control, active grille shutters—and most importantly—the fuel-efficiency boosting i-ELOOP system. So technically, the 2014 Mazda6 can be the most efficient midsize sedan. But most buyers will spring for more basic trims, which will still deliver excellent fuel economy. Midsize sedan buyers looking for greater fuel economy could also consider hybrid models, or an upcoming Mazda6 diesel model. We got to test that model last year in the European market in which it is currently on sale, and came away impressed. Source: Mazda
