Hyundai goes high tech to reach mainstream fuel economy numbers

Hyundai may have been burned back in 2011 for fudging the numbers when it comes to fuel economy, but the company is doing its best to show that it can still make fuel efficient vehicles with the next generation Sonata.
 
While the 2015 Sonata was first unveiled back in April at the New York Auto Show, the newly announced Eco model will carry the crown as the most efficient trim level for the Sonata (at least until the new hybrid variant arrives). The Sonata Eco uses a 1.6-liter turbocharged four-cylinder engine that generates 177hp and 195 lb-ft of torque.
 
Instead of going with a traditional “slush box” transmission, the engine is paired with a 7-speed dual-clutch transmission (DCT), which Hyundai says is a first in the mainstream midsize sedan market.

 
When the numbers are added up, the Sonata Eco will deliver 28 mpg in the city, 38 mpg on the highway, and 32 mpg combined. This represents a 10 percent improvement over the 2015 Sonata SE with its 2.4-liter, 185hp engine.
 
It should be noted that Nissan and Mazda are able to achieve similar fuel economy to the Sonata Eco with more powerful, less complex engines in the Altima and 6 respectively. Both competitors also used tried and true transmissions (a CVT for the Altima, and a 6-speed automatic for 6) instead of a more complex (and often times “jerky” at low speeds) DCT.

 
The 2015 Sonata Eco will have a base price of $23,275 with the only option being a $4,100 Technology Package which includes such niceties as Blind Spot Detection, Rear-cross Traffic Alert, Lane Change Assist, push-button start, dual-zone automatic climate control, 8” navigation screen, and a hands-free auto open trunk.

You would think they learned their lesson after they got smacked the first time. The biggest issue is that they are throwing in a lot tech to achieve numbers that simply aren't mind blowing.

177 hp out of 1.6 liters is quite respectable, I'd say. I've always had trouble translating mpg into European units, but those numbers seem average indeed.

That is pretty impressive, especially on 87 pump gas. I wonder what the torque curve looks like since it's a single turbo, though. It might feel very sluggish unless the chassis went on a diet.

Without substantial weight loss, they need tech to compete with the Mazda 6. Too bad nobody is doing both, although personally, I like Mazda's approach the best.

I've driven the Veloster with the 1.6 turbo. It pushes 201 hp on 87 octane gas in a lighter car.

The torque shows up early on but runs gets pretty limp when it hits the higher revs closer to redline. You have to keep the revs max a little over mid-level to get the most power out of it.

Putting a cooler version of this motor in the heavier sonata will not be as responsive. The 2.0L turbo in the earlier sonatas feels a lot more satisfying.

2014 Ford Fiesta st 1.6l turbo 197hp stock 215 with dealer installed kit. The 1liter turbo has 135hp now that's respectful

Hyundai's own Veloster turbo 1.6L engine puts out 201 hp. Not sure why they didn't use that engine, but instead put something weaker in the new Sonata. I don't expect that Sonata to be a very exciting car to drive.

This. I am getting a 32mpg ave in my 2013 Altima over the last 9k miles.

Hey DUMBASS, no one, thus far, has compared their numbers against EPA numbers. I merely mentioned MY ACTUAL MILEAGE. I did not make a comparison. So, DUMBASS, hold your tongue until someone actually does what you suggested they did.

Then what's the relevance of your post if you weren't comparing to this Hyundai?

Except his average is right around the average the EPA states.

If you lived in a congested city you would get fuel economy hugely worse than the rated fuel economy. Traffic makes a huge difference. This is why you don't compare EPA ratings with actual consumption.

I'm getting 25.8MPG average on a 2.0L Mazda 3, but that doesn't mean your vehicle is more fuel efficient than mine because I spend half the time sitting in traffic.

For reference, these are very good numbers the Ford Fusion 1.5L Turbo gets 25 city/37 hwy/29 combined, that's a pretty comparable car (it's very slightly more powerful and the same size class and price range).

You should have considered a Hybrid. M
y Camry Hybrid is rated at 40/38 MPG, and even with 100% rush hour city driving, and a short commute I'm still getting over 36 MPG.
I've also seen as high as 50 MPG on 60+ miles highway trips, and usually average over 45 MPG on the highway if I keep the speed under 70 MPH.

It would also cost an additional $12,000 and drive like a slug riding a flying carpet. I'm not complaining about fuel economy, I'm giving an example of how traffic affects fuel economy.

I'm getting 26-28 out of my 2005 Monte Carlo with a 182hp V6. Having to dump 50% of my low end torque for 10 extra mpg is not good in my opinion.

The Triton V10 in my motorhome gets 8 MPG with a very nice *10* MPG on flat stretches with a tail-wind.

But it has an "Eco" badge!! It must be good!

Seriously there's no way I could buy something named Eco-anything, or suffer a badge on my vehicle stating as such.

You can just be a regular person and appreciate saving money at the pump. But making the vehicle a sociopolitical statement, those people are disenfranchised and look elsewhere.

I know what you mean. The Eco badge means nothing to me, since I generally need a vehicle that can pull, even a small trailer. I can't complain though, managed to average, 19-20mpg on my old 97 Blazer 4wd with the 4.3 V6 in it, right till the transmission went out this last time. And that was just with upgraded plugs and wires.

One interesting thing though. The 2012 Impala my mother bought, with the newer 300hp direct injected V6. She averages around 27-29mpg daily driving, 31mpg on the highway. Pretty standard mix of country stop and go, city, and highway driving in that. And that's pretty similar to the 03 Impala she had previously, which only had a 194hp v6.

May not be great, but its fun to hear that thing growl when you need to put the accelerator down.

I might have considered this but God I just hate these new marketing names.

I couldn't care less about what car companies decide to call their trims levels etc., Eco means as much to me as SE or ES or GT whatever - ie, not a damn thing.

Only thing that matters are the numbers that actually matters, Ford can call the engine in my Focus ST Poo-Poo-Boost for all I care as long as it's still pumping out the same number.

Comparatively speaking, their badge isn't bad. A while back, I saw a Cadillac Escalade Hybrid in the gym parking lot. Let me tell you, the boys at Caddy were awfully proud of that behemoth sporting a hybrid drive train!

I think the only sides of that SUV that didn't sport some sort of "HYBRID" logo were the top, bottom and front. Back hatch, both sides (multiple times!), the dashboard and the engine all sport one.

Now that's what I'd call obnoxious badging!

That's fitting since the Cadillac Escalade IS the very definition of obnoxious.

A lot of tech ? How is a 'puter operated manual transmission more "tech" than a CVT (even w/dual clutches) ? Or how is a turbo "tech" at all ? All are pretty common fare these days. A better question might be why isn't Hyundai reaping the same benefits for the cost of their chosen tech as does ... say Ford ? For that matter what is the added cost to Hyundai of this "tech" vs what Nissan etal are doing ? Perhaps less than the cost of Mazda's conventional transmission and a GDI engine ? How much tech went into making the 6's chassis lighter and more fuel efficient ?
