During the General Motors third quarter earnings (or lack thereof) conference call on Friday, company executives discussed the vehicle introduction schedule for 2009 and 2010. Several cars that had been expected to debut during 2009 have been pushed back to the following year, including the Saab 9-4X and Cadillac CTS Coupe. GM declined to discuss any vehicles beyond the 2010 calendar year. One vehicle that notable by its absence in the list of vehicle launches is the Saturn Vue plug-in hybrid. The two-mode hybrid version of the Vue is launching production right about now and the first drives are due in about a month. The plug-in variant that was expected to launch late in 2009, although GM has never given an official date, only approximate targets. A late 2009 production launch would have made the Vue among the first, if not the first production PHEVs on market. During the call, GM president Fritz Henderson explained that the list was not exhaustive. At this point we’re still waiting to hear more from GM on the fate of the PHEV Vue.

Click the Aspen Hybrid for a high-res gallery

This week Chrysler launched full scale production of the new Aspen and Dodge Durango hybrids at the Newark, DE assembly plant. The SUVs are Chrysler’s first production hybrid vehicles and they use the same Two-Mode hybrid system that’s installed in GM’s full-size SUVs. The plant began building pilot production vehicles earlier this year to iron out any production issues and hybrid Durangos and Aspens should start appearing at dealerships in the next few weeks. Chrysler isn′t indicating how many hybrids they plan to build but they have priced the SUVs very aggressively compared to the GM equivalents. The Chryslers are only available as four wheel drives and those are priced $8,000 below the four wheel drive GM models. The Durango has a sticker price of $45,340, including $800 for destination, while the Aspen runs $45,570. Check out our first drive of the 2009 Chrysler Aspen/Dodge Durango 2-Mode hybrids.

The man in charge of hybrid powertrain development at GM Larry Nitz has confirmed that the E-Flex team has made the decision to switch engines for the range extender in the upcoming Chevy Volt. The original concept was to use a turbocharged 1.0L three cylinder engine to drive the generator. Instead they have decided to use a 1.4L normally aspirated version of the engine that will power the upcoming Chevy Cruze in turbo form. Nitz also discussed the issue of why performance of the Volt won’t be degraded when running in charge sustaining mode, the status of the Plug-in Vue and expansion of Two-Mode hybrid availability. Full explanations are available in the Green Fuels Forecast interview.

Click the Escalade hybrid for a high-res gallery

This fall, GM is adding its 2-Mode hybrid drivetrain to the Cadillac Escalade in an attempt to actually make some money off the system. Those of you who thought the existing Tahoe and Yukon hybrids were too rich for the average Joe, with prices starting at $50,000, you might want skip right past the Escalade, which is expected to be priced in the mid-70s. The Escalade uses the same 6.0L V8 as the other Two-Mode hybrid vehicles and will be available with both rear- and four-wheel-drive. The extra mass of the better-equipped Escalade means that it loses 1 mpg compared to its lesser siblings, getting 20 mpg city and 21 mpg on the highway. Unfortunately it looks like Escalade hybrid buyers will still be saddled with those ridiculous “HYBRID″ graphics along the rocker panels. If you’re interested in a tour of what will likely be the second most expensive hybrid after the Lexus LS600h, check out the video after the jump.

Dubai may sit on some of the biggest oil deposits in the world, but that doesn′t mean that they don′t want to make them last a little longer by using less locally. To that end, the Dubai Roads and Transport Authority (RTA) will be working with GM to start testing a fleet of Chevy Tahoe and Malibu hybrids for use as limos and taxis in the Persian Gulf emirate. For one year starting in January, the hybrids will be evaluated in service around Dubai to validate the durability for the application. If the program works out, the Dubai RTA may switch over their entire fleet beginning in early 2009.

General Motors and Government of Dubai to Bring Hybrids to the Middle East
Agreement could lead to one of the largest hybrid fleets in the world

Dubai, UAE - General Motors and Dubai Roads and Transport Authority (RTA) announced today an agreement for an evaluation program that will bring hybrid vehicles to the Middle East. The agreement, which includes a comprehensive local market evaluation of GM’s all-new Chevrolet Tahoe Two-Mode Hybrid and the all-new Chevrolet Malibu Hybrid, could eventually lead to one of the largest fleets of hybrid vehicles in the world.

The accord is groundbreaking because it demonstrates the common goal of General Motors, Dubai RTA and the Government of Dubai to reduce their impact on the environment - even in a region that is rich in oil-resources.

The agreement was signed by His Excellency Matar Al Tayer, Chairman of the Board & Executive Director of the RTA and Terry Johnsson, President of General Motors Middle East Operations, in the presence of Engineer Essa Al-Dosary, CEO Public Transportation Agency, Engineer Abdul Aziz Malik, CEO Dubai Taxi, and a number of department directors and officials from RTA and General Motors.

Maureen Kempston Darkes, GM Group Vice President and President of GM Latin America, Africa and the Middle East said, “We are honored that Dubai RTA selected the all-new Chevrolet Tahoe Hybrid and Malibu Hybrid for this program. This is further evidence that our environmental strategy goes to markets all around the world - and is truly a global effort to reduce emissions and develop sustainable transportation. These advanced technology vehicles are leaders in their automotive segments and selecting them is testimony to the visionary leadership of the Government of Dubai.”

His Excellency Matar Al Tayer said that this initiative comes in implementation of the directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, UAE Vice President and Prime Minister and Ruler of Dubai to seek a safe, clean and attractive and sustainable environment that lives up to the reputation and prestige of the Emirate. It also comes in the framework of RTA’s commitment to protect life and property, preserve the environment and natural resources, improve standards of occupational health and public safety, and implement all the necessary technologies to reduce noise levels caused by means of transportation.

The GM-RTA agreement calls for the provision of a small fleet of Chevrolet Tahoe and Malibu hybrids that will be used as limousines and taxis by RTA on the roads in Dubai. The program will last one year, beginning in January 2008. General Motors will provide technical training on safety and other aspects for 15 RTA technicians, along with training for 40 drivers of Dubai Taxi. During the program, GM and the RTA will work together to validate the vehicles for use and serviceability. The intent is for the Dubai RTA to consider the Chevrolet hybrids for its fleet plans scheduled for early 2009.

General Motors Corp. (NYSE: GM), the world’s largest automaker, has been the annual global industry sales leader for 76 years. Founded in 1908, GM today employs about 280,000 people around the world. With global headquarters in Detroit, GM manufactures its cars and trucks in 35 countries.

BOLD MOVES: THE FUTURE OF FORD Step behind the curtain at Ford Motor. Experience the documentary first-hand.

Original post by Sam Abuelsamid

Filed under: Hybrid, Chrysler, Dodge, LA Auto Show

At the LA Auto Show today, Chrysler showed their upcoming Dodge Durango and Chrysler Aspen Hybrids for the first time at an auto show although it’s not the first time we’ve seen them. We actually got to drive a prototype last June at the Chrysler Proving Ground. Chrysler is still nearly a year away from production of their first hybrids and obviously the mileage numbers are not finalized yet. But when Executive VP for product development Frank Klegon made the announcement, he said the Chrysler SUVs would get a forty percent improvement in city mileage and twenty five percent overall. Unfortunately for Chrysler, this falls short of what GM has achieved with the same two-mode hybrid system in the Tahoe/Yukon. Those vehicles managed a fifty percent bump in town and thirty plus percent overall. Hopefully between now and launch, Chrysler will manage to eek a little more.

Previous rumors that GM might price their new Two-Mode hybrid SUVs in the low $40K region to grab market share have proven untrue as the company has finally revealed the pricing. The rear-wheel-drive Tahoe will weigh in at a base price of $50,490 with the four wheel drive GMC Yukon topping out at $53,775 with all prices including a $900 destination charge. Without knowing exactly what equipment is included on the hybrid models, it’s hard to say exactly what the hybrid premium on these SUVs will be, although a rough guess would put it at roughly $3,000-4,000 over a similarly equipped 5.3L version. Once available tax credits are factored in though, that price gap will narrow considerably.

GENERAL MOTORS ANNOUNCES PRICING FOR CHEVROLET TAHOE AND GMC YUKON HYBRID SUVS

Manufacturer’s Suggested Retail Price for Tahoe 2WD is $50,490; Yukon 2WD is $50,945

LOS ANGELES - GM today announced pricing for the 2008 Chevrolet Tahoe and GMC Yukon Hybrids, the only full-size, fully capable SUVs whose two-wheel-drive (2WD) models offer the same EPA city fuel economy as a conventional four-cylinder midsize car.

Manufacturer’s suggested retail prices for the generously equipped Tahoe Hybrid are $50,490 (2WD) and $53,295 (4WD); and $50,945 (2WD); and $53,755 (4WD) for the Yukon Hybrid. Prices include a $900 destination charge and, based on current adjusted EPA fuel economy calculations and pending IRS approval, buyers could be eligible for a federal tax credit.

“We promised to apply our most advanced technologies to vehicles that can save the most fuel, and we are delivering on that promise with the Tahoe and Yukon Hybrid SUVs,” said GM vice chairman Bob Lutz. ” The gasoline-only Tahoe and Yukon SUVs already offer best-in-segment fuel economy. Now, consumers can choose GM’s patented 2-Mode Hybrid technology that delivers the same city fuel economy as the 2008 Toyota Camry with the base four-cylinder engine. The difference is that the Tahoe and Yukon can seat eight people and can tow up to 6,200 pounds.”

The Tahoe Hybrid is part of a commitment by Chevrolet, GM’s largest brand, to provide customers around the globe with a variety of value-driven fuel solutions that range from gas-friendly to gas-free. The Yukon Hybrid is further evidence of GMC’s engineering excellence and innovative technology. Both are among 16 gas-electric hybrid models GM is introducing during the next four years. D espite the added technology, the Tahoe and Yukon Hybrid SUVs are not the highest-priced models within their respective lineups.

Two-wheel-drive Tahoe and Yukon Hybrid models deliver EPA fuel economy of 21 mpg in the city, a 50-percent improvement over their 5.3L gasoline-only siblings and comparable to the city fuel economy of the much-smaller 2008 2.4L-equipped Toyota Camry sedan, according to figures obtained from www.fueleconomy.gov. EPA highway fuel economy is 22 mpg. The fuel savings is impressive on 4WD models, too, with the Tahoe and Yukon Hybrids rated at 20 mpg in both city and highway driving. This gives the Tahoe and Yukon Hybrids a driving range of about 525 miles per tank of fuel, or enough for a trip from San Diego to San Francisco.

Making this possible is GM’s all-new, advanced electrically variable transmission and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late-intake valve closing (LIVC) technology. GM’s new 2-Mode Hybrid system enables the Tahoe and Yukon to launch and drive up to 30 mph on electricity alone and allows the 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods. The Tahoe and Yukon Hybrids also save fuel with aerodynamic aids and reduced-mass components.

Along with exceptional fuel economy, the Tahoe and Yukon Hybrids deliver full-size SUV capability - up to 6,200 pounds (2,812 kg) of towing capacity (2WD) and 6,000 pounds (2,722 kg) on 4WD models; 12,000 pounds (5,443 kg) GCWR and eight-passenger seating capacity.

From subtle interior touches to functional exterior aerodynamic details, the Tahoe and Yukon Hybrid stand apart from the crowd. Once in the driver’s seat it is instantly clear that these vehicles are special - from the unique gauge clusters with distinctive badging to the special tachometer. Even the stylish thin-profile seats, designed to reduce mass for improved fuel savings, also provide a side benefit of increased second-row leg room.

These generously equipped, full-size SUVs include heated leather-appointed front bucket seats and leather-appointed second-row bench; driver and passenger power-adjustable seats; navigation radio with rearview camera system; a Bose premium sound system; XM Satellite Radio and the OnStar safety and security system. Other standard features include StabiliTrak electronic stability control tire pressure monitoring system; a tire inflator kit (in lieu of a spare tire); cruise control trailering receiver/equipment; two-speed transfer case (4WD); locking differential 18-inch lightweight polished aluminum wheels and assist steps.

On the outside, form follows function with numerous aerodynamic features such as a lowered air dam, shaped running boards and special rear-end treatments. They enhance the vehicles’ overall appearance and contribute to their 0.34 drag coefficient. Noise-reduction measures include a new exhaust system and resonator low-rolling resistance tires; additional engine intake induction tuning; an electrically driven, 300-volt air conditioning compressor and 42-volt variable-assist power steering; and tuning to the Energy Storage System cooling system internal fan.

Click the Silverado hybrid for a high-res gallery

Now that General Motors has launched production of their full-sized SUVs with the Two-Mode hybrid system, it’s time to spread the wealth. Along with the Cadillac Escalade hybrid that we saw a few days ago, the full-sized Silverado pickup truck is also getting the hybrid treatment. Like it’s enclosed, eight-seat cousin, the pickup will get a forty percent boost in city mileage with a twenty-five percent bump overall.

The beauty of the two-mode system in these applications is that gives a substantial boost in fuel efficiency without sacrificing the fundamental functionality of the vehicle. The two-wheel-drive Silverado hybrid can still tow 6,100 lbs thanks to the 6.0L V-8. The hybrid system allows increased use of the cylinder deactivation so that the engine runs on four cylinders under light load, with the electric drive providing power for acceleration when needed. Also like the SUV versions, the pickup has been tuned to operate with less noise under all conditions so that the difference between all-electric and engine drive modes is not as jarring. Depending on the battery state of charge, the truck can run over a mile on electricity alone at speeds up to 30 mph. The Silverado hybrid goes into production in second half of 2008. Details after the jump.

2009 CHEVROLET SILVERADO HYBRID AT A GLANCE:

• The only hybrid full-size pickup
• Silverado Crew Cab body style; 2WD and 4WD
• GM’s patented 2-Mode Hybrid system delivers 40-percent improved city fuel economy and 25-percent combined fuel economy gain
• All-electric drive up to 30 mpg (48 km/h)
• 6.0L V-8 engine with Active Fuel Management and late-intake valve closing technology
• 6,100-lb. (2,767 kg) towing capacity (2WD)
• Cruising range of more than 500 miles
• On sale in late 2008

2009 CHEVROLET SILVERADO HYBRID IS THE INDUSTRY′S
MOST FUEL-EFFICIENT FULL-SIZE TRUCK

LOS ANGELES - Affirming its commitment to fuel solutions and truck leadership, Chevrolet announced the 2009 Chevrolet Silverado Hybrid, a full-size pickup that achieves 40-percent greater city fuel economy and a 25-percent improvement in overall fuel economy. It is expected to be the most fuel-efficient full-size pickup on the market, besting the current V-8 leader - the non-hybrid Silverado.

Partnering General Motors′ patented 2-Mode Hybrid system and a powerful 6.0L gas V-8, the Silverado Hybrid delivers highly efficient performance while maintaining full-size pickup capability. The hybrid system provides all-electric driving at low speeds, allowing fuel savings to be realized even when the truck is fully loaded or towing a trailer. Silverado Hybrid can tow up to 6,100 pounds (2,767 kg).

“The Silverado Hybrid is the newest example of Chevy’s heritage of truck innovation, which stretches back 90 years, and exemplifies Chevrolet’s commitment to fuel solutions,” said Ed Peper, Chevrolet general manager. “Silverado Hybrid will deliver fuel economy comparable to many small and midsize trucks that are equipped with four- or six-cylinder engines - all while delivering the capability customers expect of Chevy full-size trucks.”

The Silverado Hybrid goes on sale in late 2008 and is based on the award-winning Silverado platform that was introduced for the 2007 model year. It will be offered in the Crew Cab body style; 2WD and 4WD models. Each model features Silverado’s “Pure Pickup” trim and comes standard with several popular features, including StabiliTrak electronic stability control system, a locking rear axle and a trailering package.

“Silverado has one of the broadest and deepest lineups of models, configurations and capabilities,” said Peper. “The Silverado Hybrid adds to the breadth and depth of offerings, while carrying the core elements that make Silverado one of the most well-equipped and safest trucks in the market.”

Silverado offers dual-stage frontal air bags and head curtain side air bags; and is the only full-size truck with five-star side impact ratings in federal crash tests.

Hybrid details

The Silverado Hybrid’s fuel-saving performance is derived from GM’s advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 Gen IV gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM’s hybrid technology system not only enables the Silverado to launch and drive up to 30 mph on electricity alone, it also allows the 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.

With GM’s 2-Mode Hybrid system, the electric power used to propel the vehicle is generated by the hybrid system itself. When the brakes are applied or the vehicle is coasting, the electric motors within the hybrid system create electricity that is stored in the 300-volt battery. This stored energy is used to move the vehicle and the regenerative braking cycle is renewed.

The 2-Mode Hybrid system provides seamless, dependable power on demand in an efficient package. In fact, its electric motor is less than half the size of those in single-mode hybrid systems. This technology was developed and is still used in fleets of hybrid transit buses in more than 70 North American and European cities. Scaled-down for use in passenger vehicles, the 2-Mode system delivers fuel savings where it is needed most - in large vehicles with high levels of capability. It is a core part of GM’s energy diversity efforts, which are centered on reducing dependence on petroleum, improving fuel economy, reducing emissions and minimizing the automobile’s impact on the environment.

With the fuel mileage savings of the hybrid system and Silverado’s 26-gallon (98-liter) fuel tank, the Silverado Hybrid has a cruising range of more than 500 miles - enough to drive from San Francisco to San Diego.

Quiet and smooth

Integration of the hybrid system on the Silverado is seamless - the battery pack is located in the chassis, beneath the rear seat - and perceptible only in what it lacks: noise.

“The Silverado Hybrid is exceptionally quiet,” said Mark Cieslak, vehicle chief engineer. “From a passenger’s perspective, the refinement of the hybrid system is quite evident throughout the driving experience, and showcases itself when the vehicle is moving under electric power.”

Contributors to the quiet driving experience include:

• New exhaust system and resonator tuned for the 6.0L engine’s Active Fuel Management operation
• Additional engine intake induction tuning for reduced interior noise and pleasing sound quality
• Low-rolling resistance, “quiet-tuned” 𓦉/65R18 tires for reduced road noise
• Electrically driven 300-volt air conditioning compressor reduces vibration and allows the HVAC system to cool the passenger compartment even when the gasoline engine is shut off. Includes the standard tri-zone HVAC system
• Electrically driven 42-volt variable-assist power steering reduces vibration and provides up to a 0.5-mpg fuel economy improvement by reducing parasitic losses common in belt-driven hydraulic systems
• Energy Storage System (ESS) cooling system internal fan is tuned to be quiet at low vehicle speeds when the fan could more easily be heard by the occupants

Along with quietness, the Silverado Hybrid also delivers exceptional driving smoothness, thanks to specifically tuned shocks for its Z85 suspension and a new, hydraulic body mount. Located on the passenger-side of the chassis, the hydraulic mount provides a dramatic improvement in highway driving smoothness, particularly on rough or choppy road surfaces.

“The hydraulic mount makes a dramatic improvement in ride quality,” said Cieslak.

Additional details specific to the Silverado Hybrid include aerodynamic aids. A slightly deeper front air dam and a hard tonneau cover for the bed reduce air drag, fostering maximum efficiency. The tonneau cover has a three-segment design that enables easy folding or removal.

Trailering performance

In addition to increased fuel economy, the Silverado Hybrid’s electrically variable transmission also provides tremendous trailering capability, enhancing the smoothness and driving quality when towing. Electric drive is enabled up to approximately 30 mph (48 km/h), even when towing, allowing fuel savings when the truck is towing a trailer.

“Along with being very smooth, the EVT always provides abundant torque at all RPM levels for easy towing,” said Cieslak. “It is particularly helpful on grades, as the EVT’s greater ratio spread allows the engine to hold optimal rpm for smooth, steady performance, with no hunting between higher and lower gears.”

The EVT incorporates grade braking and tap up/tap down shift control. It also benefits towing on curves or lower-speed back roads, as exceptionally smooth gear transitions eliminate the “shift shock” torque disruption that can occur during abrupt shifts, such as when slowing or braking.

“All-around driving performance, whether towing or not, is excellent,” said Cieslak. “The smoothness and quietness of the EVT is the icing on the cake that comes with fuel savings.”

Hybrid heritage

The 2009 Silverado Hybrid is the second full-size hybrid pickup from Chevrolet. The previous-generation Silverado was offered as a mild hybrid that professionals found useful as a power generator at worksites.

The new Silverado Hybrid, which features GM’s sophisticated hybrid system answers the needs of a broader range of customers and takes advantage of significant technological advances that have been realized since the previous hybrid was offered. The Silverado Hybrid joins the recently introduced Tahoe Hybrid, which also uses the 2-Mode system.

Chevrolet is one of America’s best-known and best-selling automotive brands. With the largest dealer network in the United States, Chevy is the leader in full-size trucks and the leader in sales of vehicles priced $35,000 and above. Chevrolet delivers more-than-expected value in every vehicle category, offering cars and trucks priced from $9,995 to $83,175. Chevy delivers expressive design, spirited performance and great value with standard features usually found only on more expensive vehicles.

The awards keep rolling in for General Motors′ new Two-Mode hybrid system. After winning the Green Car of the Year at the Los Angeles Auto Show, the system has just been awarded the Technology of the Year by Automobile Magazine. According to technical editor Don Sherman the Two-Mode system allows big SUVs to get city mileage equivalent to four cylinder mid-sized sedans. The magazine’s editors called the two-mode system the most significant advancement in power-trains since the original Prius.

AUTOMOBILE MAGAZINE NAMES THE AUDI ̼

AUTOMOBILE OF THE YEAR

–Audi R8 also captures Design of the Year GM’s Two-Mode Hybrid System named Technology of the Year–

(ANN ARBOR, Mich.-December 26, 2007) - AUTOMOBILE MAGAZINE, America’s leading automotive lifestyle publication (www.automobilemag.com) and part of SOURCE INTERLINK MEDIA, today announced that the Audi R8 is its 2008 Automobile of the Year. The magazine also named the R8 Design of the Year and GM’s Two-Mode Hybrid System Technology of the Year.

The winners are featured in the pages of the February 2008 issue of AUTOMOBILE MAGAZINE, available on newsstands beginning January 2, 2008.

2008 Automobile of the Year: Audi R8
Audi’s first foray into the sports car arena impressed the editors with its depth of abilities, which include straight-line speed, deep reserves of power, generous suspension travel, laser-like directional stability, and the surefootedness of all-wheel drive. The R8’s glass-encased, 420-hp, 4.2-liter V-8 engine has the sound of a traditional Italian supercar. Editors called it a great real-world sports car in the vein of the Porsche 911, but with the exotic presence of a Ferrari.

“The R8 absolutely captivated the automotive world this past year,” said Jean Jennings, President and Editor-in-Chief of AUTOMOBILE MAGAZINE. “It propels Audi into a whole new league of driving dynamics, and it emphatically caps Audi’s steep ascent from the somnambulant lull in which it languished in the early 1990s. The R8 is a thrilling new sports car from a company that’s stronger than it’s ever been.”

Design of the Year: Audi R8
The arresting R8 features a bright metal blade on its side, an unmistakable and dramatic design feature shared with no other car. For Design of the Year, AUTOMOBILE MAGAZINE looks for innovation, style, beauty, engineering, dynamics, heritage and public approbation, and editors noted that the R8’s design is outstanding in almost every way.

“We honor the designers and the engineers who have so perfectly realized a truly civilized grand touring coupe,” said Design Editor Robert Cumberford. “It is far more comfortable than cars of equal performance, and it features a highly focused environment for the driver but a relaxed and more open space for the passenger.”

Technology of the Year: GM’s Two-Mode Hybrid System
AUTOMOBILE MAGAZINE editors also called General Motors′ Two-Mode Hybrid System the most significant gasoline-electric propulsion advancement since the original Toyota Prius. With oil approaching $100 per barrel, big trucks that don’t guzzle gas on an ordinary commute could be a God-send.

“Two-Mode blends the best attributes of internal combustion and battery-powered electric motors,” said Technical Editor Don Sherman. “Chevrolet Tahoes and GMC Yukons equipped with the technology can achieve 20 miles per gallon or more, which is equivalent to the capability of a four-cylinder mid-size sedan in city driving.”

Sherman noted that because Two-Mode is a second-generation approach conceived by transmission experts instead of engine specialists, gasoline and electric power sources are more ingeniously combined with fixed and variable gear ratios to achieve higher efficiency over a broader range.

Since GM partnered with BMW and the former DaimlerChrysler to develop Two-Mode for front-, rear-, and four-wheel-drive applications with gasoline and diesel engines, consumers should begin to see it in more cars, pickups, SUVs, and crossover vehicles.

If you like the idea of the new GMC Yukon hybrid but can’t quite swing a little more than $50,000 to buy one, now you have the the opportunity to get one free of charge (sort of, you will have to pay the taxes on it). The cable channel HGTV is having a contest and giving away a new Yukon hybrid. As if that wasn’t good enough they are tossing in a place to park it in the Florida keys. The garage comes with a $2 million house that includes a doggy dream home for your pooch. You will of course have to pay all the taxes on that stuff too which will cost you a lot more than just buying a Yukon. If you feel like taking your chances you can enter at the HGTV web site.

Click the Two-Mode Vue for a high-res gallery

var digg_url = ‘http://digg.com/autos/GM_introduces_Saturn_Vue_Two_Mode_hybrid′; Saturn introduced the first General Motors production hybrid vehicle when the Saturn Vue Green Line appeared in 2006. The Vue was equipped with GM belt-alternator-starter (BAS) mild-hybrid system. The BAS system has subsequently been added to the Aura and Malibu sedans in addition to the redesigned 2008 Vue. The functionality of the BAS system is limited, providing start-stop functionality, some regenerative braking and some power boost from the motor. It cannot, however, run the vehicle solely on electricity.

For the 2008 Detroit Auto Show, Saturn is introducing what will be the second of three hybrid variants of the Vue. This one uses the Two-Mode hybrid technology that was introduced in 2007 on the Chevy Tahoe and GMC Yukon. Unlike the big GMT900 SUVs, the Vue has a transverse mounted engine and front wheel drive. That required designing a new transaxle that incorporates the same technology as the big trucks. Read on after the jump to learn more.

[Source: General Motors]

Because of the limited space in smaller vehicles, this transmission had to be repackaged to get all the hardware to fit. Like the rear wheel drive Two-Mode transmission, the new transverse mount version also features two electric motors. This version uses smaller 55kW motors compared to the 60kW units on the big trucks. The motors are still liquid cooled and they trade electrons back and forth with a 1.8kWh nickel metal hydride battery pack. The battery pack in the Vue is mounted under the cargo floor behind the rear seat. Unlike the air-cooled pack used in the Tahoe/Yukon, the Vue pack is liquid cooled.

Like the big truck hybrids, GM combined this Two-Mode system with the largest engine available in the non-hybrid version. That means the Two-Mode Vue uses the 3.6L “high-feature” V-6. The hybrid version is equipped with variable valve timing and direct fuel injection. The direct fuel injection allows the engine to use a higher compression ratio of 11.3:1 with less risk of pre-ignition. The engine also a knock control system specific to each cylinder that allows spark timing to be varied.

The functionality of the Two-Mode system itself is the same the rear wheel drive system. There are two hybrid modes for lower and higher speeds that use two variable ratio ranges. At higher speeds, the Two-Mode transmission also has a clutch that can lock in any of four fixed gear ratios. This mode mechanically bypasses the electric motors for greater efficiency at highway speeds.

To maximize the fuel efficiency and allow for more electric drive time, the Two-Mode Vue has an electro-hydraulic brake system that blends regenerative and friction braking. (Disclaimer: I formerly worked for the company that produces the brake system for the Two-Mode Vue and I helped develop the brake control software). Since, unlike the mild hybrid, the Two-Mode is capable of running in electric drive mode, a brake boost system that doesn’t rely on engine vacuum is needed. The electronic brake system used in the Vue (and the Tahoe) provides integrated hydraulic brake boost so that a vacuum pump isn’t needed as it is on some other hybrids. This helps simplifies packaging and reduce noise.

Regenerative braking can come in at any speed, and any combination from 100 percent regen to 100 percent friction braking is possible. The percentage of regen depends on the amount of deceleration requested by the driver’s brake application and the state of charge of the battery. Under most normal braking situations, the majority of which are less than 0.3g of decel almost all the braking will come from regen. Deceleration beyond about .35g, or when the battery is fully charged will add in friction braking. The regen limit is in part due to the rate at which the battery can absorb energy. In addition to regen blending, the brake system also provides full anti-lock braking, traction control and electronic stability control.

Other mechanical changes to the Two-Mode Vue include re-calibrated spring rates, anti-roll bars and damping rates to compensate for the changes in weight distribution the hybrid transmission and battery. The new hybrid also gets an electric power steering system. On the inside, the Two-Mode Vue varies from other models with an efficiency gauge replacing the tachometer. If the optional navigation system is included, a power flow display is available on the center stack display.

The bottom line is that the two-mode hybrid system allows the Vue to retain all the performance of the standard V-6 Vue including the 3,500lb towing capacity and 7.3 second 0-60 time. At the same time the fuel economy gets a 50 percent bump in urban driving and 30 percent overall. The Two-Mode Vue goes into production late in 2008.

GM’s Advanced Hybrid Technology Delivers Up To 50-Percent Fuel Economy Increase
With No Compromises in Performance, Capability

• First brand to offer two hybrid options on the same model
• Third hybrid in Saturn’s portfolio
• Advanced Technology Partial Zero Emissions Vehicle (ATPZEV)

DETROIT - The all-new 2009 Saturn Vue Green Line 2 Mode, the first front-wheel-drive compact SUV in the world powered by General Motors’ two-mode hybrid technology, is designed for customers who want the outstanding fuel savings of an advanced hybrid and the full power and towing capability of an SUV. The Vue Green Line 2 Mode was unveiled today at the North American International Auto Show.

The Vue Green Line 2 Mode will deliver an estimated 50-percent fuel economy increase over the non-hybrid V-6 Vue. It also is expected to have a driving range of more than 500 miles (800 km).

In addition, the Vue Green Line 2 Mode’s 3.6L VVT V-6 engine with direct injection technology ensures there are no trade-offs between performance and fuel economy. Acceleration time from 0-60 is expected to be around 7.3 seconds, and the maximum towing load will be 3,500 pounds (1588 kg).

Production is slated to begin in late 2008.

“The Saturn Vue Green Line 2 Mode challenges the notion that a compact SUV can′t be both powerful and efficient,” said Jill Lajdziak, Saturn general manager. “Customers tell us they want a compact SUV that will respect the environment and save money at the gas pump, but they don′t want to give up performance and utility. We’ve responded with the Vue Green Line 2 Mode.”

The 2009 Saturn Vue Green Line 2 Mode sports the same European-inspired design language of the non-hybrid Vue, completely redesigned for the 2008 model year. Subtle exterior changes include “2 Mode” badging on the front doors and rear liftgate; and lightweight aluminum alloy wheels and low-rolling resistance tires that enhance fuel economy. The Vue Green Line 2 Mode’s appearance is further accented by chrome door handles, chrome dual exhaust tips and chrome skid plates on the front and rear lower fascia.

The Vue Green Line 2 Mode features technologies and refinements in the fuel and exhaust systems that classify it as a Partial Zero Emissions Vehicle (PZEV) in the state of California and other states that have adopted California’s motor vehicle emissions rules. When it arrives in dealer showrooms in the fourth quarter of 2008, the Vue Green Line 2 Mode will be Saturn’s third hybrid, joining the Vue Green Line 4-cylinder hybrid SUV and the Aura Green Line sedan.

The Vue Green Line 2 Mode is GM’s first application of two-mode technology on a front-wheel-drive vehicle. The system is currently on the V-8-equipped Chevrolet Tahoe 2 Mode and GMC Yukon 2 Mode full-size SUVs, and becomes available in 2008 on the Cadillac Escalade 2 Mode luxury SUV and Chevrolet Silverado 2 Mode full-size pickup.

How the Vue Green Line 2 Mode Hybrid works

GM’s two-mode hybrid system in the Vue Green Line 2 Mode improves fuel economy by the following operations:

• Engine off at idle
• Low-speed, electric-only propulsion
• Cutting off fuel to the engine during vehicle deceleration
• Regenerative braking
• Energy-efficient accessory systems

Unlike single-mode hybrid technology found in competitors’ SUVs, the two-mode system maximizes city and highway fuel economy by integrating two electric continuously variable modes with four fixed mechanical gear ratios. The system consists of twin, active-cooled 55-kW electric motors integrated into the 2M№ automatic transmission. Energy to power the motors comes from a 1.8 kWh, 300V nickel-metal hydride battery pack, which consists of 22 nickel metal hydride modules and is packaged behind the second-row seat below the cargo floor.

The transmission is mated to GM’s 3.6L V-6 VVT with direct injection technology. In the first mode, at low speed and light load, the Vue Green Line 2 Mode operates in one of three ways depending on conditions and battery charge level: all-electric power, internal combustion engine power or a combination of the two. All reverse operation is driven by the electric motors.

The second mode is used primarily at highway speeds to optimize fuel economy. It provides electric assist in addition to six-cylinder power when conditions demand it, such as trailer towing and climbing steep grades, and to allow the engine to run at its most efficient point under less-demanding conditions.

No engine speed changes are necessary for the mode shift to occur. The result is exceptionally smooth, seamless acceleration and responsiveness. At all times, the system’s Hybrid Optimizing System (HOS) collects torque-based data, deciphers it, then determines the most fuel-efficient means of propelling the Vue Green Line 2 Mode.

Direct injection V-6 boosts efficiency

The Vue Green Line 2 Mode’s standard engine is an advanced 3.6L V-6 VVT with direct injection, a member of GM’s family of high-feature V-6s. The direct injection engine uses regular unleaded fuel and represents one of the most sophisticated applications of its kind on a hybrid SUV.

Direct injection delivers fuel directly to the combustion chambers and permits a higher compression ratio, improving fuel efficiency. Additionally, the technology reduces cold-start hydrocarbon emissions by up to 25 percent.

The 3.6L VVT with direct injection also features a U.S. auto industry-first isolated fuel injector that greatly reduces the ticking noise associated with other direct injection engines. Other noise-reduction features include the use of acoustic foam in the engine valley and cover.

Specially tuned chassis for a smooth ride

Because the hybrid system changes the weight distribution on the Vue Green Line 2 Mode, special chassis refinements such as revised front and rear spring rates; revised front and rear stabilizer bar rates and recalibrated front struts and rear shock absorbers help ensure a smooth driving experience.

The Vue Green Line 2 Mode is equipped with a “fully blended” electro-hydraulic brake system that enables 100-percent regenerative braking (batteries are charged during braking), 100-percent friction braking (traditional four-wheel disc braking) or a combination of the two. During regenerative braking, the system converts kinetic energy to electrical power, then stores the power in the Energy Storage System.

A 12V rack-mounted Electric Power Steering system replaces a conventional column-mounted hydraulic system and saves fuel - gaining up to a half-mile per gallon of gas. It also gives the Vue Green Line 2 Mode more precise steering inputs and better overall on-center feel.

Intuitive displays keep drivers in the know

The Saturn Vue Green Line 2 Mode’s instrument panel lets drivers know that they’re behind the wheel of a sophisticated hybrid, yet with gauges that are easy to understand. An efficiency gauge replaces the tachometer, informing drivers of when they are achieving maximum fuel economy; whether the vehicle is in electric-&#
