Post Hyundai Reveals Hybrid Blue Drive Architecture

Press release...

Hyundai's First U.S. Hybrid System Uses Breakthrough Lithium Polymer Batteries and Leapfrogs Existing Nickel-Metal Hydride and Lithium-Ion Technology

Hyundai Motor America announced today the launch of Blue Drive, an environmental initiative which will bring to market a family of eco-friendly Blue Drive products and establish Hyundai as an environmental leader. With Blue Drive products and technologies, Hyundai will be able to achieve a fleet average of 35 miles per gallon by 2015, five years ahead of government requirements. During a news conference at the Los Angeles Auto Show, the company revealed plans for its first U.S.-market gas-electric full hybrid (to be offered in the next-generation Sonata), introduced a sleek crossover concept powered by a turbocharged gasoline direct injection (GDI) engine, and announced future high-mileage editions of the Accent and Elantra, underscoring its global commitment to sustainable transportation.

"Hyundai aims to be the most fuel-efficient automaker on the planet," said John Krafcik, vice president, Product Development and Strategic Planning, Hyundai Motor America. "We're aligning our global R&D resources in Michigan, California, Nam Yang, and Frankfurt to develop the Blue Drive technologies we need to achieve our goal - a 35 mpg U.S. fleet average by 2015."

Hyundai's Hybrid Blue Drive Architecture

An all-new, homegrown hybrid architecture is at the heart of the Hyundai Blue Drive strategy. Hyundai's proprietary parallel hybrid drive system mates the already fuel efficient 2.4-liter Theta II engine to a 6-speed automatic transmission and a 30kW (205 N-m) electric motor for maximum fuel economy. 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, starting with the next-generation Sonata in the United States.

Hybrid Blue Drive is made up of nine major components:
1. An efficient 30kW electric motor delivering 205 N-m of torque
2. A regenerative braking system
3. An integrated starter generator that enables the engine to turn off at stops and restart automatically under acceleration
4. A breakthrough lithium polymer battery package, with 5.3 Ah of capacity at 270 volts
5. Optimized Theta II 2.4-liter engine
6. 6-speed automatic transmission with an improved efficiency electric oil pump
7. Weight-efficient architecture coupled with a low drag coefficient
8. Electric air conditioning compressor
9. Hybrid power control unit

Lithium Polymer Battery Technology

Hyundai'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.

Lithium Polymer Batteries vs. Nickel-Metal Hydride Batteries

Compared with nickel-metal hydride batteries, lithium polymer batteries deliver the same power with 30 percent less weight, 50 percent less volume and 10 percent greater efficiency over the nickel-metal hydride batteries found in all of today's hybrids. Lithium polymer batteries offer more than twice the energy density of nickel-metal hydride batteries, and 175 percent greater volumetric energy density, meaning Hyundai engineers can devote less space and weight to the battery pack. Lithium polymer batteries also hold their charge 20 times longer. Lithium polymer batteries also are more resistant to changes in temperature, which improves cycle life. And 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 batteries, 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 compared with typical lithium-ion batteries.

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 which facilitates the movement of lithium ions across anode and cathode, creating the battery current.

Traditional lithium-ion batteries are easy to handle, can withstand mild internal pressures, and have been around in various forms since 1991. That means a manufacturing infrastructure is in place, and scale economies 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 has spent hundreds of hours testing Hybrid Blue Drive's lithium polymer battery system with its battery supplier, LG Chem. This testing has proven that Hyundai's lithium polymer technology has greater thermal and mechanical stability than existing systems, meaning better safety.

Another key engineering challenge for 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.

Other Aspects of Hyundai Blue Drive - Weight Efficiency, Turbo GDI, Optimized Blue Models, and Fuel Cell Electric Vehicles

HED-5 i-Mode Concept Vehicle

At the Geneva International Motor Show, Hyundai introduced the revolutionary HED-5 "i-Mode" concept car. Today, Hyundai Motor America is announcing that a production version of this compact, spacious, weight-efficient four-cylinder crossover has been green lighted for the U.S., with timing to be announced at a later date.

Turbocharged Gasoline Direct Injection Technology

The HED-5 concept was shown with an advanced 2.0-liter Theta turbocharged gasoline direct injection (GDI) four-cylinder engine capable of developing as much as 286 horsepower, and delivering more than 30 highway miles per gallon. This engine will appear in various Hyundai models in the future.

By injecting the fuel directly inside the cylinder in a small, precise amount, combustion is improved resulting in higher fuel efficiency and lower exhaust emissions. The performance and response of the engine also improves thanks to intake charge cooling. When direct injection is combined with turbo charging, customers enjoy even better performance and fewer trips to the gas station. Four-cylinder turbocharged gasoline direction injection engines can be 15 - 20 percent more fuel efficient than V6 engines without compromising performance.

Blue Editions

Next year, Hyundai will introduce high mileage "Blue" editions of its Accent and Elantra models. These models will deliver outstanding fuel economy without adding thousands of dollars to the price. In fact, "Blue" models will be priced lower than other models, assuring they will be both efficient and economical.

Hyundai is focused on achieving an excellent MPG-per-dollar ratio with these models. Fuel-efficient modifications include low-rolling-resistance tires, enhanced aerodynamics, revised engine calibrations and reduced final drive ratios to deliver even higher mileage and lower emissions than today's models. These new high mileage editions will be identified with unique "Blue" badging.

Cool Hyundai: New 6-Speed Automatic Engine Revealed



PRESS RELEASE

HYUNDAI REVEALS NEW FUEL-EFFICIENT SIX-SPEED AUTO
  • Hyundai becomes only the third company in the world to develop its own six-speed automatic transaxle
  • Boosts fuel economy by 12%, is 12kg lighter and has 62 fewer parts than a 5-speed
  • Set to be rolled out on selected models in 2009 onwards
To help meet its goals of improving fuel efficiency and reducing CO2 emissions, Hyundai has completed the development of an all-new six-speed automatic transaxle that will boost fuel economy by more than 12.2 percent.

Designed for transverse engine applications in passenger cars and SUVs, the new compact transaxle puts Hyundai into an elite class of auto manufacturers who have designed their own six-speed automatic (after Toyota and a GM/Ford joint venture), demonstrating Hyundai's advanced powertrain engineering capabilities.

"The strength of our design is its completely unique layout, which makes it smaller, more compact and lighter than any other six-speed on the market today," said Hong-Min Kim, the project manager of the transaxle at Hyundai R&D Centre. In fact, the design is so unique and so advanced, Hyundai has applied for nearly 300 patents related to the technology.

The transaxle will first arrive in the new Hyundai Grandeur equipped with a 3.3-litre V6 petrol engine. In this application, it delivers a 12.2 percent gain in fuel economy and is 2.5 percent quicker in zero to 62mph (100km/h) acceleration times (7.8sec versus 8.0 sec). It also delivers an 11 percent improvement in 60km/h to 100km/h overtaking performance (4.0 sec versus 4.5 sec).

The unit is also maintenance-free: the gearbox is 'filled for life' with automatic transmission fluid and needs no topping up, reducing servicing costs.
Developed over a four-year period, this new six-speed automatic gearbox offers numerous technical merits. Despite the extra gear, it is 12kg lighter than the five-speed it replaces. It is also 41mm shorter and considerably simpler having 62 fewer parts, which is a key to increased durability and lower cost.

When it comes to gearsets, more is definitely better. The addition of a sixth gear enables closer spacing between ratios providing a better balance of performance and fuel economy, while the wide overall gear ratio helps deliver strong acceleration.

The gearbox has three planetary gearsets whose hallmark is simplicity of design and a unique flat torque converter, which shortens the unit's overall length by 12mm. Four pinion differentials improve durability and further minimise size.

Another example of engineering ingenuity is to be found in the design of the hydraulic pressure control unit. There are always slight manufacturing deviations from one solenoid valve to the next, which cause fluctuation in the hydraulic pressure and affect shift precision and quality. To rectify this, the transaxle features cleverly integrated adjustment screws in the valves which enable each of the eight valves to be calibrated at the factory.

This novel feature ensures stable hydraulic pressure at any shift point, which facilitates a high degree of precision and control needed to deliver ultra-fast, smooth and precise shifts throughout the engine speed range.

The new six-speed went into production this month (December). A total of five variants of the transaxle will be produced to accommodate a wide range of petrol and diesel engines. A total of 16 different Hyundai models will get this transmission including a redesigned Santa Fe, which is due to arrive in late 2009 and early 2010 in some markets.
After four years of development, Hyundai has joined the ranks of GM and Ford as the only automaker to develop its own six-speed automatic transmission in-house. The new 'box sheds over 26 pounds and 62 parts from Hyundai's five-speed unit, while increasing fuel economy by 12% and decreasing shift times. Five different variants of the six-speed will be produced, with the 2009 Hyundai Azera equipped with the 3.3-liter Lambda V6 being the first recipient, followed by 16 other models, including the redesigned Santa Fe, due to hit dealers in late 2009 or early 2010. Hyundai claims that the new gearbox is "maintenance free," and lacks a dipstick since the fluid is good for the life of the vehicle (we'll see). Hyundai is also continuing development of its eight-speed automatic which is expected to make it to market sometime next year in the Genesis sedan.

Imagine you had to develop something entirely new on your own... that you had to pave a new road but had to avoid all other roads that lay in front of you; no intersections are allowed.

It was a painstaking processs for Hyundai. But we did it. We no longer have to pay loyalty to transmission companies to use theirs, which translates to savings passed onto consumers.

Are royalty payments a significant amount in vehicle cost?

Since there were only two previous 6AT tranny's it seems that programming shift logic makes a big difference in performance since many consumers complain about the continuous hunting between gears on some cars vs others.

Kudos to Hyundai, guess I'll have to hop on the Honda bashing bandwagon for 5AT's. Any room left?

well they thought it was since they made their own unit. That torque converter is a neat thing and so are the valve adjustment screws

Congrats! very impressive, Hyundai is making leaps and bounds. I'd have to say at the moment I like Hyundai's lineup a lot more than Acura's. Hopefully in a few years they can convince more people, like my sister and my mom who consider Lexus, BMW, MB > *

No surprise, no surprise.

Hyundai-Kia is now the 5th biggest auto maker in the world. It sold a total of 3,961,629 vehicles in 2007, outselling Honda, Chrysler and Nissan.

Hyundai is the next rising superstar, closely following the footstep of Toyota.

The only problem for Hyundai is that it still has no identity. Hyundai vehicles tend to copy or closely-resemble the external styling of successful competitors, even with the latest V8 RWD Genesis.

But be prepare to see Hyundai to soon replace Honda as the most innovative leader in automotive technology.

^ And Nissan owns Jatco which makes trannies for a lot of cars. Honda is the only that still uses in-house gearbox. This is exactly like direct injection, everyone pretty much gets their injectors from Bosch. That's one of the reasons Honda backed out from the DI idea and still have no DI engines. Honda seems to dislike the idea outsourcing, even if they are behind the game.

So no more innovative technology leader for Honda/Acura.

"Advance" and "behind the game" doesn't go together.

Only "Follower" and "behind the game" goes together.

It was a painstaking processs for Hyundai. But we did it. We no longer have to pay loyalty to transmission companies to use theirs, which translates to savings passed onto consumers.
Who's we? Did you help build it?

I don't think Honda/Acura has ever been a technology leader in every category. They have always been about fuel efficient since day 1...they were behind the game with the V6 engine, and now they are behind with V8. I don't think anything has changed much. They came up with the NSX which was very innovative though, but that's pretty much it. They have been consistent with bringing out new things once in a while though. Major ones that I can think of are CVCC, then VTEC, followed by hybrid, and the SH-AWD that came up recently. Seems to be pretty consistent to me.

On a side note...I'm not sure why the word "Advance" comes up all the time...lol..may be it's because that's Acura's slogan? Acura Advance? I don't know but clearly it's not AdvanceD...meaning it's on its way of being advanced..?? man.that's confusing eh...lol...just like Lexus.."the pursuit of perfection".....none of their cars are perfect yet...

Indeed the word "Advance" comes up all the time. You can't miss it, you can't escape it. It's on every damn Acura advertising media. Just click into the official Acura.com website, and the very first thing comes up to your face is the Acura brand logo, below it the name "Acura", and the word "Advance." further below.

Audi has since dropped the "Never Follows" slogan, ever since it is scrambling to follow Acura to release a version of the L/R torque splitting AWD system. Maybe Acura should consider changing it's slogan too.

Hyundai: Development and Technology news

Itís official: Hyundai is currently hard at work developing an automatic transmission with no less than 10 gears.

Hyundai representatives revealed the news to Car and Driver but were tight-lipped when it came to discussing when the gearbox might arrive and which cars it will be used in.

Previous rumors suggested that the amply-ratioed transmission could hit the market in 2014, possibly in the brandís Genesis and Equus luxury sedans. C & D, however, speculated that the autobox could make its way to the Elantra and Accent in order to boost the small carsí already respectable EPA numbers even higher.

Transmissions have been gaining gears at a rapid clip in recent years, and it remains to be seen when automakers will call it quits on what must surely be a game of diminishing returns. If the news from Hyundai is any indication, however, donít expect the proliferation of almost semi-like gearboxes throughout the industry to stop any time soon.
