The wholly renewed 2015 Hyundai Sonata is on the verge of launching here in the United States, but it appears there's a bit more to the story first told at the New York Auto Show earlier this year. Hyundai has just revealed the first images and details of the Sonata Eco, a new entry in its midsize sedan lineup that combines a small, turbocharged engine and dual-clutch transmission to achieve an estimated 28 miles per gallon in the city and 38 mpg highway.

That new powertrain is Hyundai's 1.6-liter turbocharged inline-four, rated at 177 horsepower and 195 pound-feet of torque. That power is sent through a new, seven-speed dual-clutch 'box – the first gearbox of its type in the segment. Hyundai points out that the Sonata Eco's 32 mpg combined rating offers a 10 percent improvement over the 2015 Sonata SE with its 2.4-liter naturally aspirated inline-four.

38 mpg highway is pretty impressive, especially considering rivals like Toyota's electrified Camry Hybrid musters up only one better, with 39 mpg on the highway (though its 43 mpg city fuel economy is, obviously, much better). And while Hyundai still has not detailed news about a next-generation Sonata Hybrid, we've heard the company is still committed to offering one.

The 2015 Sonata Eco starts at $23,275, not including $810 for destination. This represents a $2,125 price increase over the base Sonata, and the only option available on the Eco is the $4,100 Technology Package which includes a whole host of amenities, including heated leather seats, blind spot monitoring, proximity key and a navigation system with eight-inch screen among many other niceties.

2015 SONATA ECO DELIVERS ESTIMATED 32 MPG COMBINED FUEL ECONOMY AND PREMIUM DRIVING EXPERIENCE

New 7-Speed Dual-Clutch Transmission Paired With 1.6-liter Turbo Four Maximizes Efficiency, Fun


FOUNTAIN VALLEY, Calif., June 19, 2014 – Hyundai today announced the third powertrain available in the 2015 Sonata.

Sonata Eco is the first Hyundai product to utilize a new seven-speed dual-clutch transmission, which no other mid-size sedan offers. This innovative powertrain helps Sonata Eco deliver an estimated 28 mpg city and 38 mpg highway. The estimated 32 mpg combined rating is more than a 10 percent improvement over a 2015 Sonata SE powered by the 2.4-liter Theta II engine.

2015 Sonata Eco comes standard with all the features of Sonata SE plus a chrome grille, side mirror-mounted turn signal indicators, automatic headlights, a 10-way power driver seat with lumbar support, stitching on the instrument cluster hood, chrome interior door handles, 5-inch color touchscreen audio, a rearview backup camera and Blue Link® telematics system.

      I don't understand why people are comparing it to Mazda6 Yes, Mazda6 GT gives 2 mpg more, but it also costs $6600 more. Even if you purchase top of the line Tech package, Mazda6 will still be $2500 more expensive. The extra 2mpg won't even break even the extra cost.

        The base Mazda 6 with Auto gets 26/38 MPG. It starts at $22895. Which is a few hundred less than the Eco Hyundai.

          They don't call the Sonata Eco to use premium fuel. .GM 1.4T uses regular unleaded and sees 40+ mpg. And in some cases owners are pushing into the 50 mpg range. No Skyactiv can do that and has just been trumped with more power, torque, and ffuel economy.

          nor do they pay for premium gas! 39mpg regular is like getting 43+mpg on premium price wise. Mazda clearly wins there. Pretty much any 35mpg car on regular costs less per mile than 39mpg on premium. But also you must not know your car specs. This hyundai ia 177hp and 195lb-ft The Mazda is 184hp and 185 lb-ft The hp and torque are a wash

          the skyactive is hardly high strung. Its max torque is at 3250rpm which is quite low. Turbos can have more torque down lower but not until the turbo spools up to full boost. Off boost at low rom they will have less torque than the same NA engine. So if you are in a turbo cruising at a low rpm and punch it, it will not be as responsive as a non-high strung NA engine. It will have more torque once the turbo spools and that lag is generally larger with higher compression turbos. And the hyundai may not require premium but i guarantee that if you dont use premium you will not get those hp numbers. The higher the compression then more critical high octane fuels will be.

          @normc32
          bonehead: the difference between the 1.6 and larger NA engines is WHERE in the RPM bands you get your torque peak. Turbos have more tq lower than NA engines. For a family sedan I would rather have a turbo than a high strung NA engine. And did I miss where the 1.6 requires premium fuel?

        Prez- Same with my 2013 Accord. I routinely see 38hwy with a N/A 2.4L. 31-34 tank averages are not uncommon. And 0-60 in 6.6sec is just icing on the cake. :) Not bad for a car that has an EPA 34 Hwy rating.

      I call baloney, i have a 2012 Sonata and i once took a drive to Atlantic City, wide open road, no traffic, i just put it on cruise and i was getting .....................45MPG. Stunning. Now when you drive in regular conditions and you can not use cruise....99% of the time the very same car gets 22 MPG on the highway. So these numbers are baloney, they get these ratings because they test in perfect conditions using cruise, people can't recreate these conditions on daily basis. I would ask for a test drive on the highway and see the REAL mpgs the car gets.

      When the 2015 Legacy publishes 36 hwy with AWD, a FWD car that only does about 6% better is not that impressive.
        Dump
        • 6 Months Ago
        @wilkegm
        That may also mean that newer AWD systems don't add as much typical power losses as they used to. I would bet that a FWD Legacy gets maybe 1-2mpg more hwy than the AWD version - which would make it just as unimpressive as the other competition.

      So more cost and complexity gets you the same mileage as a base Altima, but with a lower powered engine in a heavier car.... I think this is headed the way of the Malibu e-Assist.

        i wish people would compare cost per mile. When you have a v6 getting 33mpg on regular its equivalent price wise to a car getting 37mpg on premium. Id rather have the extra 100hp and 1mpg less (cost wise) in that case.

          lets see what Hyundai says about their own turbo cars.... " Horsepower and torque increase substantially, generating 274 horsepower at 6,000 rpm and 275 lb.-ft. at 2,000 rpm, operating on premium fuel. The engine's anti-knock sensors are designed to automatically adjust ignition timing and engine mapping to allow the engine to run perfectly on regular fuel in exchange for downgrades in power to 260 horsepower and 260 lb.-ft. of torque." " Horsepower increases by 42 ponies this year, to 348 horsepower at 6,400 rpm, and torque is up 29 lb.-ft. to 295 at 5,100 rpm when burning premium unleaded fuel. On regular unleaded, horsepower drops to 344 while torque measures 292 lb.-ft." So both decrease in power however the turbo decrease is far more substantial. And the turbo relies on a knock sensor detecting damaging knock that can harm the engine. Thus it retards the timing and reduces power. Unknown from this is its effect on mileage though another solution for knock elimination is to run rich (more gas) and thus obtain even worse mileage. http://autos.jdpower.com/content/article-auto/3QlA6pT/5-fast-facts-about-the-2013-hyundai-genesis-coupe.htm

          @bonehead
          Complete BS, Car makers design the engine to run on the type of fuel they recommend. High performance engines like those in the Focus ST say right in the manual what the HP will be with Premium (also NA engines like the Coyote in the Mustang) but most family car turbos are designed to run on 87. Get your FACTS, straight not your ASSUMPTIONS. High compression used to require 91= octane but not in todays engines.......ever heard of technology? Seen what Mazda's compression ratios are even with 87? Your screen name fits you perfectly. Either you are a troll or a paid blogger. You dont have a clue what you are talking about.

          • 6 Months Ago
          @bonehead
          very few turbos function properly without premium fuel and if they do they willl not achieve advertised hp. High compression requires higher octane

        You are correct, v6 Accord gets 34mpg on the highway according to fueleconomy.gov. Shame on that Picasso guy for "correcting" you. It gets 32 mpg using s6, AKA paddle shifters.
