    [​IMG] Just after the 2019 mid-model year updates, Hyundai adds a new AT that handily improves efficiency across most of the Elantra lineup.

    Wayne Gerdes – CleanMPG – May 15, 2019

    2020 Hyundai Elantra

    The almost perfect first time buyer, Rideshare, and low TCO compact is even better.​

    2020 Elantra Pricing vs 2019 (MSRP)

    SE w/ the 2.0L and IVT - $18,950, +$650 over the 2019 MY.
    SEL w/ the 2.0L and IVT - $19,700, +$200 over the 2019 MY.
    Value Edition w/ the 2.0L and IVT - $20,600, +$100 over the 2019 MY.
    Eco w/ the 1.4L GDI-T and 7-speed DCT - $21,250, +$200 over the 2019 MY.
    Sport w/ the 1.6L GDI-T and 7-speed DCT - $23,800, +$100 over the 2019 MY.
    Limited w/ the 2.0L and IVT - $22,800, +$100 over the 2019 MY.

    D&H for the 2020 MY Elantra's are $920, no change from the 2019 MY.

    For those following the Rideshare Total Cost of Ownership Study here at CleanMPG, the 2018 Elantra ECO has proven to be an excellent solution after 115,000 miles to date thanks in part to its ultra-low purchase price, low refueling costs vs competitors, low maintenance and repair, and possibly the lowest total cost of ownership of any vehicle you can purchase new today!

    The 2020 Hyundai Elantra, with its all-new and quite unexpected Intelligent Variable Transmission (IVT) transmission, is ready to move the efficiency bar yet again. Alone with better fuel economy, the hard charging brand adds Forward Collision-Avoidance Assist (FCA) as standard equipment to the Elantra lineups war chest.

    [​IMG]2020 Hyundai Elantra Intelligent Variable Transmission (IVT)

    Hyundai’s new IVT provides improved efficiency and simulates gear shifts like a standard AT. This transmission performs continuous shifts by modulating pressure of the transmission’s pulley, depending on driving conditions and driver inputs. It utilizes a wide ratio pulley system, which provides a broader ratio of operation when compared with its competitors. This allows for improved fuel economy at higher gear ratios and improved performance at lower ratios.

    As opposed to a steel belt, the IVT uses a chain belt, a world’s first in the compact car segment. A chain improves fuel efficiency by an ~ 1.2 percent when compared with a conventional steel belt system.

    2020 Elantra Trims Fuel Economy Improvement due to the IVT

    2020 Combined MPG vs 2019 Combined MPG

    SE w/ 2.0L and IVT: 35 (+2) vs 33
    SEL w/ 2.0L and IVT: 34 (+2) vs 32
    Value Edition w/ 2.0L and IVT: 34 (+2) vs 32
    Limited w/ the 2.0L and IVT: 34 (+2) vs 32

    SE manual transmission and Sport MTs were discontinued.

    2020 Hyundai Elantra Engine Specs

    The Elantra SE, SEL, Value Edition and Limited offer the 2.0L MPI Atkinson Cycle engine with 147 horsepower, the Eco continues to offer the 1.4L GDI-T w/ 128 hp is now rated at an EPA estimated 36 mpg combined fuel economy rating, 1 mpg over the 2016 – 2019s 35 mpg thanks to a new Start/Stop system.

    2020 Hyundai Elantra SmartSense Safety

    The 2020 Elantra offers a new list of standard advanced safety features.
    • Forward Collision Assist (FCA) uses the car’s front-facing camera to help detect an imminent collision and avoid impact or minimize damage by braking
    • Lane Keep Assist (LKA) helps prevent accidental lane departure by sensing road markings, automatically steering the car if necessary
    • Driver Attention Warning (DAW) system monitors a spectrum of driver-related characteristics to help detect driver fatigue
    SmartSense features included on the Elantra Limited with Ultimate Package include:
    • Smart Cruise Control (SCC) using a radar sensor mounted on the lower front grille maintains a set distance from the vehicle ahead in varied traffic conditions by automatically adjusting vehicle speed as necessary
    • Safe Exit Assist may sound an alert when a vehicle approaches from behind, letting passengers know it may not be safe to open the door to exit the vehicle
    • Forward Collision-Avoidance Assist with Pedestrian Detection utilizes both the front forward-facing radar and camera through sensor fusion to help detect a vehicle or pedestrian, and warn the driver of a potential collision. If the driver does not react to avoid the impact, the system may apply emergency braking in certain circumstances
    Blind-Spot Collision Warning with Rear Cross-Traffic Alert and Lane Change Assist is available all trims except SE.

    Early Conclusions

    The addition of Start/Stop to the 1.4L GDI-T mated to the 7-speed DCT equipped Eco trim is gimmicky as it provides little in fuel savings for the average driver when a possibly larger AGM battery cost replacement overwhelms the perceived or actual lower fuel costs.

    If the IVT mated to the same 2.0L I4 produces as indicated, the SE, SEL, and Value addition could be the new go to choice for a std. compact for high efficiency and low total cost of ownership.

    The 2020 Elantra arrives in dealer showrooms this month.

    Interesting! CVT questions:
    1. Can you set it to NOT fake shifting through silly fixed ratios?
    2. Is that chain CVT system similar to the (German?) one in a circa 2007 Ford 500?
    3. What specifically is the mechanical efficiency? (If you're not allowed to reveal that, just give me the efficiency of "a conventional steel belt" CVT, and I can handle adding 1.2%.)
    4. Is there a torque converter for start-up? Or mechanical clutch? If not, what?

    HI Edwin:

    The Elantra MT is gone for 2020 in both the SE trim and Sport. :(

    Hi RedylC94:

    1. The fake shift ratios are embedded in the shift programming.

    2. I believe the chain is similar to those developed over a decade ago but I am not sure. The steel belts in conventional CVTs look like chains with no sprockets between the sheaves just as the IVT does so I am speaking outside my knowledge base.

    3. For the 7-speed DCT in the Eco trim, it was something like 98 percent IIRC whereas the Sonata Hybrids std. AT without the torque converter was in the 95 or 96 percent range. Std. ATs are down in the low 90s IIRC.

    4. If you look at the IVT transmission pic, it sure does look like their is a torque converter along the left side? I am just not sure?

    I am skeptical about the 2.0L's efficiency improvements - SE trim matching that of the 16 - 18 Eco trim. The Eco's 1.4L is one of those drivetrains that is simply punching way beyond its weight. I have never experienced even close to the same level of efficiency from the 2.0L variants and I have driven all of them as the 1.4L.

    I was asking about the efficiency of this chain CVT versus a "conventional" belt CVT, not about DCTs or standard automatics. You said they claim it's better than conventional belt CVT. I'd bet it's not as efficient as a DCT (or an old-fashioned manual). Possibly close to a conventional automatic with the converter in locked mode?

    I whole hardheartedly agree. The 7-speed DCT is essentially an automated manual which is the reason for its sky high efficiency ratings. And all the problems associated with its automation. I do not know the efficiency of this CVT and probably never will. I will send a note to the PR team and see if they have that available. They provided me with the Eco trims DCT and the Sonata Hybrids 2+ years ago but that is where it stopped.

    The CVT belt, steel belt, or chain is fraught full of inefficiencies from the two high pressure pumps at the sheave pressure plates to plain friction across on average 50 percent of the sheave to belt contact surface at any given moment. The reason they are used is because they are much less expensive and far lower weight than a std. AT with its numerous clutches, meshed gear sets, and control functions.

    Hi All:

    I had to go to the EPA data files to retrieve them but here are the 2020 Elantra Lineup official EPA ratings.
    • 2020 Hyundai Elantra Eco - 33/41/36 mgUS city/highway/combined
    • 2020 Hyundai Elantra SE - 31/41/35 mgUS city/highway/combined
    • 2020 Hyundai Elantra SEL/VE/Limited - 30/40/34 mgUS city/highway/combined
    Not bad!

    I had a Ford 500 CVT rental in 2004. I remember thinking "I could drive this car for ten years and never go over 2000 RPM."
    The only time the Prius goes over 2000 is in the mountains , so...……. not so often in IL.

    The advantages of CVT designs vs multi-speed planetary automatics is the wider ratio spread possible within the small space available.
    To get the same ratio spread in a 8/9/10 speed automatic, there are more clutches and each one adds drag when not applied. In the Hyundai 6 speed that the CVT replaces, there are five friction clutches and only two are applied at any given time. Those that aren't applied are adding drag/resistance that lowers efficiency. The CVT has a simple planetary gearset and two clutches - forward and reverse. So there is only one clutch not applied and creating drag. The chain is more efficient than the belt, says Hyundai, although they don't give much more detail than the referencing the angle of the inner pully surfaces. I suspect it has something to do with the chain being more flexible than the belt but there isn't much information out there.

    The ZF 9-speed gets around the drag problem buy using two dog clutches since they have no slip when engaged and no drag when not, but that opens a whole other can of worms getting them applied when the car is in motion. A dog clutch is what you are engaging when driving a manual and moving the shift lever. The difference is the manual transmission has a clutch pedal and synchronizers to equalize speed between the gears to avoid grinding. The ZF box has neither and relies on the computer disregarding the accelerator position and tapping the throttle until engine speed is close enough to engage the dog clutch without ripping it apart. Think of it as shifting gears in without pressing the clutch pedal and using only the accelerator to get the speed just right to pop the lever into the next gear. The problems in making this happen are baked into the design and the ZF 9 speed will never be a smooth-n-snappy gearbox.

    DCT will always win the efficiency race because it doesn't need to use energy pressurizing fluid and there are no wet clutches to cause drag. But dry DCT designs will always feel like a robotically-shifted manual and not everyone likes that feeling.

    Hyundai is jumping into the CVT pool with both feet - with the Elantra getting it for now and next up the Venue. I expect it to end up in the Accent before long. Kia is already using it in the Forte and 2020 Soul, too.

    Seems the 2020 Elantra is 3-4 MPG better than our 2013 six speed automatic & 2016 six speed manual Elantras. Feather footing real MPG for the 2013 Elantra, averaged 39MPG, pencil & paper, for its first year using ethanol free gasoline. Our 2016 manual Elantra averaged 35 MPG, but under heavy stop & go conditions, a different driver AND most often using E10. Recently, the 2013 auto Elantra got 43 MPG(trip computer), while passing over a 3000+ mountain pass. The 2016 manual Elantra, got 46MPG (trip computer), while passing over a 4000MPG mountain pass, in both directions. Tho I like CVT(IVT) transmissions while driving them (don't like my mechanic to repair them tho), I'm happy with our auto & manual transmissions, neither car(at a total 130,000 miles) needing any repair, ever. The 2020 Elantra is "seemingly nice", but our 2013 & 2016 Elantras are "proven great".

    Proving the greatness of our manual Elantra again(successfully sued by lead foot drivers for poor economy):
    The other day, my wife & I drove to Mt. Rainier, over 4600 foot Cayuse pass, 5500 foot Chinook pass, to Yakima, up to Snoqualmie pass & back home, obtaining 44MPG. The 2016 manual significantly out-performs our 2013 automatic Elantra in the mountains & suspect, will out-perform the 2020 CVT, at least in the mountains.... & probably other places.

    Sure glad I got our manual in the best looking Elantra ever. Probably still got 200,000 miles to use it (longer?).

    Our 2016 Venetian Red Elantra(built in the U.S.), compared to our 2013 Venetian Red Elantra(built in S.Korea), has slightly more metal-flake, with a deeper red AND more depth. STILL, much more metal-flake is called for..... bbbiiiiggg chunks of metal-flake, deep in the paint. Ford has excellent paints. If ya pay extra, Toyota, Chevy & Chrysler have nice paints. Went to a Mazda dealer once, thinking their paints had to be good....& was disappointed.
