Chrysler announces Aspen Two-Mode hybrid

In a move that would have come as a surprise only if it hadn't happened, Chrysler has announced that the Aspen SUV will join the Dodge Durango early next year in getting a hybrid drivetrain. The Durango hybrid had already been announced and Chrysler has now confirmed that both variants will pair the Two-Mode hybrid system with a 5.7L Hemi V-8.
The Hemi is also equipped with cylinder deactivation that can turn off four of the eight cylinders under light load conditions. Chrysler is claiming a twenty-five percent improvement in overall fuel efficiency and forty percent improvement in city driving. The Two-Mode system is being jointly developed by General Motors, DaimlerChrysler and BMW. The Chrysler press release and a video of Mark Chernoby, VP of Advanced Vehicle Engineering are after the jump.

Aspen Joins Chrysler Group Hybrid Lineup And Yeah, It's Gotta HEMI®!
• Chrysler Aspen Hybrid joins Dodge Durango Hybrid in 2008
• Vehicles feature 5.7-liter HEMI® Hybrid with Multi-displacement System (MDS)
• HEMI Hybrid delivers more than 25-percent fuel economy improvement
• Full-size SUVs to boast nearly 40-percent mpg improvement in the city
• Chrysler Group's advanced hybrid system leapfrogs traditional hybrid design
Auburn Hills, Mich. - That new Chrysler Aspen Hybrid gotta HEMI®?
Yes, it does – as does the new Dodge Durango Hybrid. Both vehicles, powered by Chrysler Group's all-new 5.7-liter HEMI Hybrid powertrain, debut next year as the first volume-production hybrid offerings from the Chrysler Group and the first vehicles to feature DaimlerChrysler's advanced two-mode hybrid technology.
"The all-new Chrysler Group HEMI Hybrid will offer our customers the best of both worlds: renowned performance and significantly improved fuel economy," said Frank Klegon, Executive Vice President – Product Development, Chrysler Group. "With the new HEMI-powered Chrysler Aspen Hybrid, we are delivering the ultimate combination of fuel efficiency, overall performance and capability in a premium full-size SUV."
The new 5.7-liter HEMI Hybrid is expected to deliver an overall fuel economy improvement of more than
25 percent, including an improvement of nearly 40 percent in the city.
The HEMI powerplant, in hybrid form, will continue to feature Chrysler Group's Multi-displacement System (MDS), which allows the engine to seamlessly alternate between four-cylinder mode when less power is needed and V-8 mode when more power is in demand. For the fifth year in a row - and every year since its 2003 re-introduction - Chrysler Group's famous 5.7-liter HEMI engine has earned a place on Ward's 10 Best Engines list.
The new Chrysler Aspen Hybrid and Dodge Durango Hybrid vehicles represent a bold change in what is generally a "me too" category. Chrysler Group's full-size hybrid vehicles will deliver seamless dependable power on demand in an efficient package. With an electrically variable transmission (featuring two electric motors), two full hybrid modes of operation, and four fixed mechanical gear ratios, the drive system improves fuel economy around town and at highway speeds.
Chrysler Aspen
Boasting elegant Chrysler styling, unsurpassed capability and performance and abundant premium amenities, the Chrysler Aspen is a premium SUV that is a value alternative to luxury-priced competitors. Offering more for less, Aspen features numerous premium features, elegant Chrysler design, 30 safety features and best-in-class horsepower, torque and interior room.
Two-mode Hybrid
Chrysler Group's two-mode hybrid powertrain - jointly developed by DaimlerChrysler, General Motors and the BMW Group - represents a major automotive industry milestone due to the unprecedented fully integrated combination of electric motors with a fixed-gear transmission.
As a result of the low- and high-speed electric continuously variable transmission (ECVT) modes, the system is commonly referred to as the two-mode hybrid. However, the sophisticated fuel-saving system also incorporates four fixed gear ratios for high efficiency and power-handling capabilities in a broad variety of vehicle applications. The new Chrysler Aspen Hybrid and Dodge Durango Hybrid vehicles can be powered either by the electric motors or by the 5.7-liter HEMI V-8 engine – or a combination of the two. During the two ECVT modes and four fixed-gear operations, the hybrid system can use the electric motors for boosting and/or regenerative braking. When full power is needed, the system automatically adjusts for passing, driving steep grades or hauling a trailer. The result is trend-setting hybrid technology that provides superior fuel economy, performance and load-carrying capability.
Joint Development Center
Located in Troy, Mich., the DaimlerChrysler, GM and BMW Hybrid Development Center jointly developed the overall modular two-mode hybrid system and the individual components: electric motors, transmission, high-voltage battery, high-performance electronics, wiring, safety systems, energy management and hybrid system control units. In addition, the Hybrid Development Center is responsible for system integration and project management.
Chrysler Group Advanced Propulsion Technology
Hybrid technology is one part of Chrysler Group's advanced propulsion technology umbrella, which also includes efficient gasoline engines, advanced clean-diesel technology, and ethanol flex-fuel and zero-emission fuel cell vehicles. DaimlerChrysler is the only automaker building plug-in hybrids and testing them with customers in the United States.

If the Aspen is a "gussied up" Durango. Then what is an Escalade or GMC? answer a "gussied up" Chevrolet Tahoe

Did anyone else laugh out loud when they said that it "saves fuel by only using the gasoline engine when absolutely necessary?"
The stock Aspen gets 14/19mpg, so with their claimed 40% and 25% boosts, this hybrid Aspen will get 20/24. Impressive gains, but apparently gas is "absolutely necessary" an awful lot of the time.

To 1,
Escalade has a different motor and transm. than the tahoe and yukon (therefore not just dressed up). Yukon and tahoe are the same but they are at different retail outlets and make no bones about being just that, the same.
#2 lol, yea that is an awsful lot of the time. (they need those good o to 60 times)

This kind of story should never be in AutoblogGreen -- you're fuelling the misconception that 'hybrid'=green.
Post #2 alludes to this. The standard Hemi Aspen gets 14/19mpg according to the EPA. You’d be lucky to achieve this in the real world. Adding the claimed improvement (also based on the EPA ideal testing conditions) and you’ll be lucky to crack 20mph for an average tank.

I swear there must be some conspiracy at the domestic manufacturers. Notice all the "real" hybrids they introduce are SUVs? Seriously, are the oil companies paying them off or something? If Chrysler wanted to be original they should've introduced a Caliber hybrid, or maybe a Sebring hybrid.

Since Daimler-Benz is dumped Chrysler, it seems unlikely that the 7g-tronic would be coupled to the 5.7V8.
So isn't Chrysler's 6 speed auto ready? 68RFE or RLE
5.2:1 vs. 4.5:1 ratio spread is a decent upgrade.

Please forgive my ignorance but I am very new to this "green car" thing. With regard to posts #4 and 5 (identical), can you explain the difference between "hybrid" and "green". I thought that hybrid technology is supposed to be more envronmentally friendly (although a V8 doesn't automatically bring environmentally friendly to mind).
Thanks for any clarification.

Big SUVs, Silverados and F-150s burn an average of a 1,000 gallons of fuel per year. If the national fleet of big vehicles were replaced with more economical two-mode hybrid transmissions, it would save a lof of fuel. With fuel cost nearing $3.50 a gallon, the desire to upgrade to these vehicles should be a winner. And I sure can't pull my RV with a prios...

An accent that gets 40 mpg should be in the hall of fame. At least it should be tested to see why it is getting 40% more than the average accent. My civic hybrid averages 48 with 80% freeway driving. The old 50 60 mpg does not exist in anything except the insight. 40 does not exist in anything except hybrid and small diesel ie VW.

You granola hippies should go hate on big oil and leave my mopar alone. My wife and I plan on purchasing a hybrid aspen to replace our 2000 dodge durango next year. We have a large family and often need our SUV for towing loads, this two stage hybrid system coupled with the multidisplacement system (MDS) will allow us to reduce emmissions while still having the available power when we need it. Ford and Toyota's hybrid SUV's are not available with tow packages and were not designed to be taken off road. At least Dodge/Chrysler offers a solution.
We do the majority of our driving in a 2002 Hyundai Accent which achieves 42mpg (real world driving, not just an inflated EPA estimate) on the highway, nearly as good as a hybrid compact. Not to mention the Accent cost just 9K new, compared to 20K for a entry level prius/civic hybrid.

Chrysler claims they "leapfrogged traditional hybrid design"? Afraid not. Their "dual mode" is similar to the hybrid designs used by GM for transit busses for years now.
"Hemi" is the favorite advertizing buzzword for Chrysler, and doesn't mean much other than it has a hemispherical combustion chamber. Whooptydoo.

The big picture is Alternative Fuels. Hybrids wont be worth a damn when we run out of oil.
I drive a 2007 Jeep Commander with the 4.7L V8 Flexfuel engine. I only buy E85, usually 30-90 cents cheaper than regular and i get about 18 mpg city and 22 mpg hwy. which is way above the estimates given for it.
So for a 20 gallon tank i only use about 3 gals of gas which for you hybrid people who drive foreign, that is almost 100 mpg Gas.
In addition to all of you that have problems with auto industry fuel economy. The biggest consumers of Oil are: Heating, Power Plants, Plastic Industry, Commercial Jets, Cosmetic Industry. The Cars and Light trucks of today do not even rank in the top ten consumers of Oil. So maybe we should look at alternatives for the other industries.
Like a company called CEREPLAST which produces plastics and resins from plants, which are 100% bio-degradeable.

I think that the two mode hybrids SUV's are a good idea for those of us that have a big family.We can't very well get four children and two adults in a Pruiz or a Malibu,this is a tight fit in my Intrepid..Kudos to GM,Diamler,and BMW for their work on this.This is great for those that would like to "go green",but can't for lack of room for the whole family..
