The motor generates 30 kilowatts (40.2 horsepower) and 151 pound-feet of torque and handles drive and regenerative braking duties. That's well short of the 106 hp of the Ford Fusion motor and the 141 hp of the Toyota Camry motor. Nevertheless, Hyundai claims the Sonata can operate in EV mode at up to 62 mph. We'd guess that actually means the Sonata can shut down the engine and cruise on electricity at high speeds but can't actually accelerate to that speed on battery power, but we're looking into it. Hyundai takes advantage of the motor's instant-on torque to make the top three gear ratios of the transmission longer for lower engine speeds when cruising.



The duty of restarting the engine after it is switched off is handled by an integrated starter generator similar to the one previously used by General Motors on its mild hybrid system. It's not entirely clear why Hyundai has gone this route instead of just using the traction motor like other systems, but we'd wager it probably has something to do with some pesky patent held by another manufacturer.

As we suspected, Hyundai has re-calibrated the 2.4-liter direct injected inline-four so that it operates on an Atkinson cycle. The Atkinson cycle uses late closing of the intake valve to give a shorter effective compression stroke than the power stroke. The overall efficiency of the engine is improved at the expense of low end torque production. As with the gear ratios the extra torque available from the motor is used to mask the engine's reduced output. The total combined output of the engine and motor is now slightly better than the standard Sonata at 209 horsepower, beating all competing models.



The Sonata hybrid marks the first North American (the Elantra and Kia Forte hybrids have been on sale in Korea since mid-2009) hybrid application of lithium polymer batteries. These cells supplied by LG Chem are very similar to the cells that General Motors will be using in the Chevrolet Volt battery later this year. The 1.4 kilowatt-hour pack weighs just 95.9 pounds compared the 123.9 pound nickel metal hydride equivalent in the Camry hybrid.

Weight savings extend to the whole car as well. Because Hyundai engineered the new Sonata without the possibility of installing a V6 engine it was able to reduce the mass of the structure. The curb weight of the hybrid Sonata is just 3,457 pounds, some 263 pounds less than the Fusion, which is likely to give it a performance advantage over the Ford.



Hyundai has also incorporated the other typical features of modern hybrids including a system for blending friction and regenerative braking, electric power steering assist and electric air conditioning.

Hyundai is projecting that the Sonata will hit 37 mpg on the EPA city cycle and 39 mpg on the highway cycle. While that falls a bit short of the Fusion's 41 mpg city number, it beats the 36 mpg highway rating and handily tops the Camry's 33/34 mpg ratings. What we don't know at this point is how much the Sonata will cost. As much as we like the Fusion, its nearly $28,000 starting price is a bit steep compared to its conventional IC counterparts. If Hyundai follows its usual route of undercutting the competition on price, things could get very interesting especially among those consumers that like their hybrids to look like something different.

HYUNDAI SONATA HYBRID DEBUTS AT NEW YORK AUTO SHOW

Breakthrough Lithium Polymer Batteries Leapfrog Existing Nickel-Metal Hydride and Lithium-Ion Technology

NEW YORK, March 31, 2010 – As global automakers work out implementation timing for new fuel-efficient powertrain technologies such as gasoline direct-injection (GDI), twin-scroll turbochargers, and full-hybrid powertrains, Hyundai announced today that the all-new 2011 Hyundai Sonata is the first vehicle in the industry to offer all three technologies with the new Sonata 2.0T (turbo) and Sonata Hybrid joining the hot-selling GDI-equipped Sonata in Hyundai showrooms later this year.

At the New York auto show today, Hyundai unveiled its 2011 Sonata Hybrid, changing the game in hybrids with unique approaches in hybrid powertrain design, battery technology and vehicle appearance. The Sonata Hybrid is Hyundai's first hybrid in the U.S. market.

"The Hyundai Sonata Hybrid is the new kid on the block, but it's not a follower," says John Krafcik, president and CEO, Hyundai Motor America. "Its full parallel hybrid configuration and breakthough lithium polymer batteries offer a new take on traditional hybrid design, while its unique design sets it apart from the mid-size hybrid pack."

The Hyundai-developed Hybrid Blue Drive architecture is a full parallel hybrid drive system, which can operate on an electric motor, gasoline internal combustion engine, and a combination of the two depending on driving conditions and driver demands. Hyundai's proprietary full parallel architecture differs from the power split technology used by most competitors, allowing significant efficiency advantages at higher speeds. Hyundai Hybrid Blue Drive is the first and only system using lithium polymer battery technology – leapfrogging competitive in-market nickel-metal hydride and lithium-ion applications. Lithium polymer offers the benefits of lithium-ion, a technology used in laptops and cell phones, but adds robustness, power-density and package flexibility, making it ideal for automotive applications. Hyundai Hybrid Blue Drive also is unique in its use of the company's own highly efficient, compact new 6-speed transmission, modified with hybrid starter-generator, electric motor, and low-friction oil pump, which together allow the elimination of the traditional torque converter.

Hyundai Hybrid Blue Drive is a new addition to a full suite of eco-focused products and technologies that Hyundai offers in its goal to be the auto industry's global eco-leader. According to the EPA, Hyundai has led the U.S. industry in fuel economy for 2008 and 2009, and is currently the only automaker with average fleet fuel economy of more than 30 miles per gallon.

"Hyundai applies advanced technologies to vehicles to provide the best solutions for the everyday driver," said Krafcik. "Unlike traditional hybrids that trade off highway fuel economy for higher city ratings, the Sonata Hybrid delivers best-in-class highway fuel economy, while still delivering about a 40 percent improvement in city fuel economy compared to a Sonata equipped with the Theta II GDI engine. We think this is a better balanced approach for the majority of car buyers."

PERFORMANCE

Sonata Hybrid's projected best-in-class highway fuel economy of 39 mpg offers significant benefit to hybrid owners with highway commutes, while also offering outstanding city fuel economy of 37 mpg. Government studies have shown that the typical U.S. driver operates in a highway mode 57 percent of the time. Hyundai's approach to deliver class-leading fuel economy in highway mode provides a unique solution in the mid-size sedan hybrid market, and differentiates Sonata Hybrid from the likes of Toyota Camry Hybrid and Ford Fusion Hybrid. Sonata Hybrid delivers typical hybrid fuel economy gains in the city like its competitors, but also gives owners outstanding fuel economy on the highway, where these competitors fall short.

Sonata Hybrid delivers class-leading electric-vehicle operation at steady-state speeds of up to 62 miles per hour. Gasoline engine engagement depends on state of charge, acceleration and vehicle speed. Its two propulsion units develop a total output of 209 horsepower at 6,000 rpm, exceeding all mid-size competitors, and 195 lb-ft of torque. The weight-efficient architecture of the new Sonata platform, combined with the lightweight lithium polymer battery pack, make the Sonata Hybrid the lightest vehicle in the segment, at just 3,457 pounds, 263 pounds lighter than the Fusion Hybrid. Combined with Sonata's best-in-class horsepower rating, Sonata Hybrid has a significant advantage in power-to-weight ratio, a key enabler of both performance and efficiency.

Hyundai's proprietary parallel hybrid drive system is the heart of the Sonata Hybrid. The competition uses a power split system with a planetary-geared Continuously Variable Transmission (CVT). This is where the Sonata Hybrid gains a key advantage. Competing hybrid models use electric motors that have to power a planetary gear set. By utilizing a full parallel drive system, Sonata Hybrid uses the power from the electric motor more efficiently to directly control the vehicle, allowing it to be operated at much higher speeds than the competition in EV-only mode. This technology is also a key enabler of Sonata Hybrid's best-in-class highway fuel economy.

HYUNDAI'S HYBRID BLUE DRIVE ARCHITECTURE

Hyundai's Hybrid Blue Drive is a proprietary parallel hybrid drive system that runs on the already fuel-efficient 2.4-liter Theta II engine (169 horsepower at 6,000 rpm and 156 lb-ft of torque at 4,500 rpm) mated to a 6-speed automatic transmission and a 30kW (151 lb-ft) electric motor for maximum fuel economy. Hyundai's Hybrid Blue Drive has an all-electric mode and a parallel drive mode. This means the wheels are turned by power coming directly from the gasoline engine, or the electric motor, or both together, as conditions demand. This parallel hybrid drive architecture will serve as the foundation for future hybrid drive vehicles to be developed by Hyundai.

In the Hyundai Hybrid Blue Drive system, the Theta II with multi-port fuel injection (MPI) operates on an Atkinson Cycle. Atkinson Cycle is a type of internal combustion engine strategy designed to dramatically increase fuel efficiency through changes in compression and power strokes in the four stroke engine. It is typically only used in hybrid systems where the high-torque electric motor boosts low-end power, which is traded off for internal combustion engine efficiency. By combining the electric motor and the Atkinson Cycle engine, the Hybrid Blue Drive system delivers best-in-class highway hybrid efficiency.

To further improve fuel economy, all of the Theta II major driveline and cooling system components have been optimized to reduce friction, while the crankcase has been filled with low friction oil. Hybrid Power Control (HPC) management software automatically shuts off the engine when the vehicle comes to a halt, cutting emissions to zero. When pressure is reapplied to the accelerator pedal, the Hybrid Starter Generator (HSG) automatically restarts the engine. This control strategy assures that maximum efficiency is achieved during gentle acceleration and greater power is immediately available during full acceleration. During deceleration, braking regeneration comes into play. Sonata Hybrid also features "smart brake" technology in which braking input over-rides accelerator pedal input.

The high-tech, all-aluminum, 16-valve engine also features Continuously Variable Valve Timing (CVVT) on both camshafts and newly developed engine components to reduce friction. This optimized Theta II engine achieves 10 percent better fuel consumption over a conventional Theta II engine.

Hyundai Hybrid Blue Drive uses the company's proprietary 6-speed automatic transmission rather than a conventional hybrid's CVT. Hyundai's strategy involves an adaptation of the modular 6-speed transmission, replacing the torque converter with an electric motor and high-efficiency oil pump. This technique uses a traditional step-shift 6-speed transmission rather than a CVT to provide a more traditional shift feel that is preferred by customers and sometimes artificially replicated in CVT applications. This saves on cost, making the Hyundai Hybrid Blue Drive system a better value. It is a more robust and elegantly simple solution to a complicated engineering challenge.

Fuel efficiency improvements are evident throughout Sonata Hybrid. For example, the top three gear ratios in the transmission have been extended to ensure the engine runs at lower RPMs, the electric motor-assisted steering system reduces demands on the engine, and low resistance tires further optimize fuel economy.
  • Hybrid Blue Drive is made up of the following major components:
  • An efficient 30kW electric motor delivering 151 lb-ft of torque
  • A regenerative braking system
  • An integrated starter generator that enables the engine to turn off at stops and restart automatically under acceleration
  • A breakthrough lithium polymer battery package, with 5.3 Ah of capacity at 270 volts
  • A fuel-efficient Theta II 2.4-liter engine
  • 6-speed automatic transmission with an improved efficiency electric oil pump
  • Weight-efficient architecture coupled with a low drag coefficient (.25 Cd target)
  • Electric air conditioning compressor
  • Hybrid power control unit

LITHIUM POLYMER BATTERY TECHNOLOGY

Sonata's hybrid system stores its electrical charge in a 270V lithium polymer rechargeable battery (5.3Ah/270V) that surpasses existing nickel-metal hydride and pending lithium-ion applications. Lithium polymer batteries are more durable and space-efficient than other hybrid batteries. They are also more weight-efficient. The Sonata Hybrid's battery pack weighs just 95.9 pounds versus the Camry Hybrid's 123.9 pounds. The compact battery pack resides in the forward portion of the trunk to maximize cargo space.

Lithium Polymer Batteries vs. Nickel-Metal Hydride Batteries

Compared with nickel-metal hydride batteries, lithium polymer batteries deliver the same power with 20-30 percent less weight, 40 percent less volume and 10 percent greater efficiency over the nickel-metal hydride batteries found in today's hybrids. Lithium polymer batteries offer 1.7 times more energy density than nickel-metal hydride batteries, allowing Hyundai engineers to devote less space and weight to the battery pack. Lithium polymer batteries hold their charge 1.25 times longer. Lithium polymer batteries also are more resistant to changes in temperature, which improves cycle life. Additionally, lithium polymer's self-discharge rate is less than a third of a nickel-metal hydride battery.

Lithium Polymer Batteries vs. Lithium-ion Batteries

Lithium-polymer has significant advantages over lithium-ion, including higher energy density and lower manufacturing costs. Lithium polymer is more resistant to physical damage and can handle more charge-discharge cycles before storage capacity begins to degrade. Lithium polymer technology also offers significant advantages in thermal robustness and safety.

A key difference between traditional lithium ion batteries and Hyundai's lithium polymer battery solution is the overall packaging of the cell – the anode, the cathode, the electrolyte, and the encasement material. Traditional lithium-ion batteries, like those found in laptops, use what's known as the 18650 cell format. In this format, each mass-produced cell is 18 mm. in diameter and 65 mm. tall, which is a bit larger than a "AA" battery. Each of these small metal cylinders is filled with a liquid electrolyte that facilitates the movement of lithium ions across anode and cathode, creating the battery current.

Traditional lithium-ion batteries are easy to handle, withstand mild internal pressures, and have been around in various forms since 1991. That means a manufacturing infrastructure is in place, and economies of scale are reasonably high. However, they do have several disadvantages. For example, their cylindrical shape reduces packaging efficiency and they are surprisingly complicated to manufacture since they have so many small parts. These small parts make them robust to thermal fluctuations and add significant cost and weight to the overall battery system. Cell-to-cell consistency also is extremely critical in a vehicle battery package, since the pack is only as robust as its weakest cell. Traditional lithium-ion batteries have considerable cell-to-cell variation, while Hyundai's lithium polymer batteries deliver outstanding cell-to-cell consistency.

Lithium polymer technology uses a completely different approach. Rather than using a liquid electrolyte, which requires a robust metal casing, lithium polymer batteries use a polymer gel as the electrolyte, which allows the use of a thinner and lighter aluminum-walled encasement, or pouch. Inside each lithium polymer cell, the cathode, separator, and anode are laminated together, enabling much simpler and more reliable manufacturing. This allows the battery pack to be about 20 percent smaller than a lithium-ion battery pack, making it much easier to change the cell footprint to fit the nooks and crannies of available vehicle space.

Hyundai and its battery supplier, LG Chem, have spent hundreds of hours testing the Hyundai Hybrid Blue Drive lithium polymer battery system. This testing has proven that Hyundai's lithium polymer technology has greater thermal and mechanical stability than existing systems, meaning better safety and performance.

Another key engineering challenge for Hyundai Hybrid Blue Drive has been assuring maintenance-free battery operation over the vehicle's life – at least 10 years, and 150,000 miles – in all weather conditions. Heat is the enemy of battery cycle life. Hyundai's thermal imaging testing shows how much cooler a lithium polymer battery is compared to today's nickel-metal hydride battery or a conventional lithium-ion battery. Consumers will notice these advantages in improved useful life and lower maintenance costs.

FLUIDIC SCULPTURE DESIGN ADDS A UNIQUE ECO FLAIR

Hyundai designers have taken Sonata's fluidic sculpture design language a bit further with Sonata Hybrid, making it even more aerodynamic. The goal was a modern, eco-friendly design, with "at-a-glance" differentiation from the non-hybrid Sonata models.

Unique exterior design elements
  • Headlights and taillights
  • Aerodynamic bumper fascias
  • Aerodynamic rocker panels
  • Bold hexagonal grille
  • Eco-spoke wheels
  • Air dam and aero side sills
  • Hybrid Blue Drive badging
  • Exclusive hybrid paint color

Interior refinements
  • Supervision cluster with eco-display options
  • Unique interior color choice
  • Unique seat patterns


The Sonata Hybrid also offers drivers a way to be more engaged in fuel-efficient driving thanks to Hyundai's Hybrid Technology Display. The Hybrid Technology Display is featured on a 4.2-inch LCD screen located between the odometer and tachometer, or is visible on the optional seven-inch navigation screen. It features the following information:
  • Driving mode
  • Energy flow within the vehicle
  • Engine and motor movement
  • Fuel level
  • Battery power levels and charge status
  • Electric vehicle mode indicator
  • Average and instant mpg

The Hybrid Technology Display's most unique feature is an Eco Level scoring system. The high definition display acknowledges eco-focused driving with eight levels of sky color, ranging from gray to bright blue. It also accumulates points in Total Eco mode over time. An Eco Guide also provides instant fuel economy feedback.

      Amazing what investing in some R&D can do for a company.
      • 4 Years Ago
      this is truly impressive because


      1. class leading hp
      2. best Highway 39mpg
      3. 2nd best city 37mpg(but real world numbers are supposed to be better than fusion)
      4. most likely priced aggressively like all other hyundais
      5. different design than non hybrid sonata
      6. taillights - a true masterpiece. never seen anything like it
      7. class leading interior volume
      8. class leading torque
      9. 10/100k warranty
      10. class leading 62mph


      Hyundai used to be nothing but a follower. now they want to lead the pack. Hyundai is taking over.



        • 4 Years Ago
        Where do you get these real world numbers from and why are their highway numbers real but the Fusions are wrong? Hyundai's have always been priced lower then the competition not because they want to but because they have had to! If you look at retention of value they have not held their value for leases anywhere near Toyota or even the new Fusion and if you check they have taken up the slack by selling to Hertz and Avis since Ford and GM stopped to get better resale values. Those 10 year 100,000 mile warranties that you show cost auto makes more then any other form of incentives and will drive up the cost of latter models. I would also like to point out that when you drag race a Sonata verses a Toyota 4 cylinder (with lower HP) the Toyota beats the Sonata up to 40 miles per hour where most people need it to get on the highway or to pass, the Sonata and Toyota are then equal to 60 it is then the Sonata takes off where no one needs the extra speed.
        They are now offering cars that are very good but in the past they were second rate. I bought my father in law a Sonata and all the fake Chrome is pealing off and cuts your hands when you grab the interior handles, he also has had three clutches replaced by 60k! It is still a better then average car but no better then any GM or Ford of the same year. I have been in the after market car business for 27 years and can tell you that with the exception of two or three Hyundai models most car lots wholesale them as fast as they get them. They are offering some very good cars now but they are still just an other boring middle class sedan that 90 percent of us would never buy. Just think of the two year old Acura,CTS,G35 or BMW that you could get for the same price and actually drive with a smile on your face! When was the last time you heard someone say "One Day I Want A Sonata!"
        • 4 Years Ago
        Lol, at Steve's post. Another Ford fanboy trying to put Hyundai at a bad light. When you see so many Ford fanboys trying to do whatever they can to badmouth Hyundai, you know Hyundai's doing something right!
        • 4 Years Ago
        correction

        Altima has more torque. i got confused with turbo. still very impressive.. only reason that i won't buy this is probably because it will be out of my price range. i'll just be happy with 25k sonata turbo.. :)

      • 4 Years Ago
      Once again Hyundai has taken a huge leap forward in the design and engineering of thier product. I am very pleased with this new Sonata in so many ways(styling,pwrtrain,interior design,etc) If Honda and Toyota continue to offer boring,bland,underwhelming products, they are going to get thier clocks cleaned by Ford and Hyundai.This hybrid is at first glance blessed with knockout, distinguishing good looks which clearly earns it deserved notice.If they can continue the high quality, value pricing, and best warranty in this model too, it's a clear winner.

      I happen to really like the look of the hybrid from headlamp/LED running lights,to wheels, to aero kit and lowering,to interior,to the best looking and innovative tailamps ever.I've driven the Fusion hybrid and give Ford huge kudos for producing a great car that also happens to be a hybrid.My few objections are it's high price,'look-a-likeness' and the CVT tranny.Thank you Hyundai for using a modern six speed conventional automatic.

      I predict that unless there is a dramatic series of faults to this car when tested,we are looking at the next COTY. I'll be looking forward to the upcoming turbo version that hopefully they'll put a decent suspension under. Drive baby drive...
      • 4 Years Ago
      Shouldn't they just design cars with aerodynamic efficiency in mind from the start? Part of the cost of a hybrid is paying for all these modifications made in the name of efficiency. If they applied the same effort to regular combustion cars I bet they could lower mpgs and save on production costs. Am I simplifying things too much?
      • 4 Years Ago
      Sweet! I think I would like to get one of these eventually! :)
      • 4 Years Ago
      Looks pretty goofy in the front. Less fuel efficient than a Fusion hybrid. Could still sell decently if the price is right, but doesn't seem like it would be worth it.
        • 4 Years Ago
        As the article states, Hyundai is using a very mild hybrid system. Its electric motor is only 40hp while the Fusion's is 106hp, Toyota's is 141hp. Regardless, the Sonata Hybrid still makes 209hp (Fusion makes 191hp), weighs less so performance should be better, has more interior space and cargo room, and its highway mpg is 3mpg better than the Fusion. I also suspect the price will be cheaper than the Fusion. And I personally like the looks over the Fusion. Is that reason enough?

        BTW: MotorTrend did some real world tests with the Fusion and Camry hybrids and found the Ford's numbers not quite up to par...

        looks like fusion is the only one with 100+ hp on electic motor. but why only has 191 total output? does anybody know?



        • 4 Years Ago
        It depends on what kind of driving you do. The Sonata Hybrid gets 4mpg less in the city than the Fusion Hybrid but 3mpg more on the highway. The combined ratings are nearly the same. The Sonata Hybrid is lighter and more powerful as well. I think it'll all depend on pricing.
      • 4 Years Ago

        As usual, Hyundai has simply stolen another manufacturer's design language.

        In this case the front clip is lifted straight from any number of Ford products, e.g. the Fiesta.

        The mpg on this pig is nothing to write home about either, being bested by Ford and Toyota's offerings in this segment.

        Rear really is the best part. i love how they made it look similar but different. looks even better than the non-hybrid's rear.

        I think this car is pretty ugly, especially its mangled face.
        • 4 Years Ago
        Personally, I think it looks far better than the "melted-mass-of-chrome" look of the non-hybrid car.

        WOW! Hyundai is relentless! sweet! i think this looks even better than regular sonata!
        • 4 Years Ago
        I on the other hand prefer the look of the non hybrid model. Not really feeling that huge black plastic looking thingy in the center of the "nose".

        Looks-wise, I think all the new sonatas are hideous and look like they are melting. I find the fusion much more attractive. I will admit the new sonata has an attractive interior though.

        Krafcik just said the 'real world' city is better than the rest of competition including fusion's so called 41mpg city.

        google HCD8 concept which is from 2004

        and google Hyundai Arnejs concept which was developed in late 05 shown in 06.


        Hyundai has been using the big 'fish' like grill since 2004. much earlier than Ford.

        The front headlights and taillights are sick! and the front grill is interesting.. Being different means it takes some time to get used to, but i'm sure once you do, you'll appreciate the look.

        This actually looks a lot like the Elantra and that is not a bad thing

        Just like 40 is the new 30 (and, gasp! - 20 is the new 10!) - Hyundai is the new Lexus. While Toyota is digging it's own grave by trying to save money instead of building the highest quality vehicles it can, Hyundai is stepping up and doing exactly what they did to everyone else.

        I've been saying this for years. Hyundai is no joke.. Nobody believed me (or a couple of other people who said the same thing) - but now it's kind of obvious...

        also, is this mean no one should ever buy Lexus HS 250h? this will be like 30k tops, but HS can go up to 45k!

      Man, I'm even more proud to have bought a Hyundai (Genesis Coupe) - they are on FIRE! Hopefully this thing performs as it is supposed to and is up to the high quality of the rest of the Hyundai lineup.

      Camry much ?



      HORRIBLE FRONT END. Like the taillights tho...cute. I just feel like Hyundai doesn't have their own path....their just following everyone else by doing exactly what their doing and making.

        It's the same way where a C- student would start studying what the A+ student is doing. After years of hard work, the C- student is now getting an A+. I'm sure this is just the beginning for Hyundai.

      Hyundai is stepping it up yet again!

      To the writer, though, I have to ask, what is a "neutron molecule?"
