2015 Hyundai Sonata: The Long Road to Phoenix

by Dan Edmunds, Director of Vehicle Testing on November 26, 2015

2015 Hyundai Sonata

Duty called me to a business trip in Arizona, where I would hear all about the new Nissan Titan XD. My destination in Phoenix wasn't all that far away, so the decision between driving and flying was easy. Our 2015 Hyundai Sonata sedan got the call because I hadn't road-tripped it yet.

Nominally, the drive to Phoenix is a simple six-hour interstate cruise. But my event started in the morning and I'd lose an hour changing time zones. I had to leave the day before and grab a hotel, and since it was a day off I decided to stray off course and take my time. I'd never been to the Organ Pipe Cactus National Monument before, and I had my eye on a couple of other random spots.

All told, my elongated figure-eight round-trip route would amount to well over 1,300 miles.

2015 Hyundai Sonata: Balance of Power — A Case For and Against the Four-Cylinder Turbo

by Josh Jacquot, Senior Editor on November 18, 2015

2015 Hyundai Sonata

I recently spent a day driving Kia's Optima, the counterpart to the Sonata. Though the two cars look different, they're mechanical twins, depending on equipment, of course.

Our long-term 2015 Hyundai Sonata is fitted with the volume-selling 2.4-liter normally-aspirated four-cylinder. However, the Optima I drove happened to be the SX Turbo trim, which comes with the 2.0-liter four-cylinder turbo. The 2.0-liter turbo is the top engine available in the Sonata and Optima, but it no longer competes with the optional V6s available in the Camry and Accord.

This, frankly, makes no sense.

2015 Hyundai Sonata: Fuel Economy Update for October: A Little More Led in Our Step

by Kurt Niebuhr, Photo Editor on November 5, 2015

2015 Hyundai Sonata

October proved to be another uneventful month with our 2015 Hyundai Sonata. While most of us have always found the Sonata a capable companion, Dan Frio and Carlos Lago got busy picking some nits. Far from heavy criticism, but still relevant, are things like slightly lackluster audio system, clattery engine sounds and a still not-as-refined as-we'd-like suspension.

Meanwhile, Carlos found out the hard way that our Sonata lacks the rear passenger air vents we've come to expect from many midsize sedans.

2015 Hyundai Sonata: Fuel Economy Update for September - Long-Distance Runner

by Dan Frio, Automotive Editor on October 6, 2015

2015 Hyundai Sonata

It was another busy month for our 2015 Hyundai Sonata: nearly 2,500 miles added to the odometer in September. That's a lot for a car that many of our staff (and apparently our readership) finds boring, drab, competent, uninspired, and other degrees of faint praise. For the record, I like this car more every time I drive it, but that's for another post. 

Josh's trip to the Bay Area accounted for about a third of our September miles, and although he may have only averaged 30.2 MPG on his trip, his miles helped lift the Sonata's lifetime average a couple of points, from 25.9 to 26.1 mpg.

One of his tanks was even a record-setter: 127.4 miles covered using just 3.6 gallons. That works out to 35.7 mpg, exceeding the Sonata's EPA highway rating.

2015 Hyundai Sonata: Fuel Economy Update for August - Many Miles Moves the Needle

by Dan Frio, Automotive Editor on September 28, 2015

2015 Hyundai Sonata

We stretched the legs of our long-term 2015 Hyundai Sonata in August, adding about 3,000 miles to the odometer. A couple of long road trips comprised almost half of those miles, but we ranged pretty far afield even when staying local. Of the 11 times we filled the Sonata in August, five of those tanks covered 300 or more miles.

2015 Hyundai Sonata: Excellent Road Trip Car

by Ed Hellwig, Executive Editor on August 27, 2015

2015 Hyundai Sonata

After more than 700 miles behind the wheel of our 2015 Hyundai Sonata this past weekend, I'm sold on its road trip capabilities. Here's why.

It has great seats. This is surprising since they don't boast much of a pedigree. They're not heavily bolstered or infinitely adjustable. They're not air-cooled or even covered in leather. But after several multi-hour stints behind the wheel, I rarely got uncomfortable. No squirming around to keep my rear end awake or any noticeable lack of lumbar support. I hardly noticed them at all which is good.

2015 Hyundai Sonata: Fuel Update for July - Steady Gains Toward EPA Rating

August 10, 2015

2015 Hyundai Sonata

In July, while doing our best not to blow our fingers off like our NFL role models, our 2015 Hyundai Sonata kept its air dam down and covered another 1,000-plus miles. And while there wasn't much to report, short of an alignment correction and surpassing 10,000 miles, that's not a bad thing as no news is usually good news.

But we did dump a bunch of fuel in our Sonata and you came here to see how efficiently it was used, so let's not waste any more time.

2015 Hyundai Sonata: Fuel Economy Update for June: New Records for Best Range and MPG

July 10, 2015

2015 Hyundai Sonata

June was a busy month for our 2015 Hyundai Sonata as we added close to 2,000 miles to the odometer. A good chunk of that came from Phil Reed's road trip to Mount Whitney plus some long-distance driving of my own. The result was a rise in our lifetime fuel economy average and a new fill-up mpg record.

2015 Hyundai Sonata: Real World Numbers

July 2, 2015

2015 Hyundai Sonata

Preparing to leave on a road trip, I filled up our 2015 Hyundai Sonata and was shocked to find that it only got 16 mpg for that tank. The previous tank was much better at 22 mpg, but still well below the EPA-promised 29 mpg combined. Looking at our fuel economy updates, I see other editors have flagged this discrepancy.

But, hey, what better side benefit for a road trip than to check the fuel economy? So I filled up before I left, once on the road, and again when I returned from the 609-mile excursion.

Here's what I learned about EPA estimates versus real-world MPG in our Sonata.

2015 Hyundai Sonata: Fuel Economy Update for May — Overall Mileage Improves

June 8, 2015

2015 Hyundai Sonata

After a slow April, our 2015 Hyundai Sonata racked up nearly 1,800 miles in May. Scott Jacobs gets credit for many of those miles thanks to a trip to northern California. He found that he liked the manual shift feature even if the engine wasn't always strong enough to make a pass.

2015 Hyundai Sonata: Clawing Back MPG In Eco Mode

May 19, 2015

2015 Hyundai Sonata

Somebody has to drive our 2015 Hyundai Sonata in Eco Mode. The boss ain't gonna do it. Might as well be me.

With 60 mostly-highway miles ahead of me and light, nighttime traffic, I figured this might be a good time to try out Eco mode. In this scientific, controlled experiment, I simply wanted to see if I could endure the commute tethered to the electronic ballast, namely duller throttle and lower rpm upshifts.

It wasn't so bad.

2015 Hyundai Sonata: Fuel Economy Update for April - City Miles Drop Our Combined Average

May 13, 2015

2015 Hyundai Sonata

It was a rather uneventful month for our 2015 Hyundai Sonata. We only added around 500 miles to its odometer and most of those were in town. As a result, it turned in one of its least-efficient tanks so far at just 17.5 miles per gallon. That dropped its overall average to 24.7 mpg, which is well below its rated number in combined driving.

2015 Hyundai Sonata: Earns "A" and "B" Ratings From Edmunds

April 10, 2015

2015 Hyundai Sonata

By virtue of utilizing Hyundai's 2.4-liter four cylinder engine, our long-term Sport trim 2015 Hyundai Sonata earns a "B" rating from our editors. Other models in the Sonata line score higher. Read on to discover why.

2015 Hyundai Sonata: Fuel Economy Update for March

April 6, 2015

2015 Hyundai Sonata

Our long-term 2015 Hyundai Sonata didn't go on any long road trips during the month of March. It hit the 5,000-mile mark early on in the month, but from there it was mostly city miles and short commutes for the Sonata.

2015 Hyundai Sonata: Fuel Economy Update for February

March 5, 2015

2015 Hyundai Sonata

In February we didn't use our 2015 Hyundai Sonata Sport for any road trips. Much of the driving was commuting around in Edmunds' home base of Los Angeles. In total, we added about 1,500 miles.

As a result our fuel economy for the month hovered around the lower end of the spectrum.

2015 Hyundai Sonata: Fuel Economy Update for January

February 4, 2015

2015 Hyundai Sonata

January was an active month for our long-term 2015 Hyundai Sonata. We drove it for 1,373 miles and gave the Sonata its first track-test and evaluated it on our standard ratings loop.

2015 Hyundai Sonata: Road Trip to the Rock, Part 2

January 14, 2015

2015 Hyundai Sonata

Picking up from where we left off in Road Trip to the Rock, Part 1, the trip back from Morro Bay, California to Orange County in the 2015 Hyundai Sonata Sport went smoothly.

Sunday traffic was pretty light, partially in thanks to a reasonably early start time. The lack of stop-and-go no doubt helped the Sonata's fuel economy numbers. The 31.3 mpg we achieved for this almost-entirely highway trip was a bit off the EPA's 35 mpg highway estimate for the Sonata Sport. There was a very minor bit of puttering around town.

Data from the trip:
Total roundtrip miles: 512
Actual trip mpg: 31.3
Onboard indicated trip mpg: 34.2

2015 Hyundai Sonata: Fuel Economy Update for December

January 7, 2015

2015 Hyundai Sonata

Our 2015 Hyundai Sonata Sport logged 1,824 miles in December, its first month of service in our fleet. It averaged 26.0 mpg for the month, a bit below its EPA rating of 28 mpg combined (24 city/35 highway).

Our best fill of the month was 31.7 mpg during a mostly highway road trip to Morro Bay, while our worst fill was 23.0 mpg. It achieved a best range of 370.4 miles, and that's likely to increase in upcoming months as editors experiment with how far they can run the Sonata's fuel tank down.
