Chrysler plans hybrid Dodge Ram
At the 2008 SAE International World Congress, Chrysler announced plans to release a gasoline-electric hybrid Dodge Ram pickup truck in 2010. Frank Klegon, Chrysler executive vice president of product development, said the new hybrid is part of Chrysler's effort to revitalize its product portfolio.
Last year, Chrysler partnered with German supplier GETRAG to develop new dual-clutch transmissions, which will debut this spring. Dual-clutch technology features two independent gear sets with separate clutches. During shifts, the next gear is anticipated and selected. Then one clutch is opened while the other is closed, allowing shifting without torque interuption. This is expected to result in better performance, as well as a 5 to 10% fuel economy increase in future Chrysler Group vehicles.
The new technology will be available in international markets on the all-new 2009 Dodge Journey, the 2009 Dodge Avenger and the 2009 Chrysler Sebring.
"Chrysler's new dual-clutch transmission is the next step in transmission technology, offering consumers improved fuel economy along with smoother and quicker shifting," Klegon said in a prepared statement. "This important new Chrysler technology is one of several initiatives we have in place to directly focus on improving fuel efficiency across our vehicle lineup."
Greener Auto Technology: Part by Part
The SAE International 2008 World Congress began on Monday, April 14 in downtown Detroit. Stricter CAFÉ provisions and other regulations are making fuel efficiency this year's focus. From magnetized steering wheels to soam foam seats, the companies and people attending the trade show are working to increase fuel efficiency one part at a time. Weight is a critical issue. Thus, carbon fiber is huge because it is both stronger and lighter, providing improved performance and efficiency.

Update on the Chevy Volt
More than just a concept
On April 4, General Motors announced that it will begin road testing the batteries for its Chevrolet Volt plug-in hybrid electric vehicle this month. In response to the hype surrounding the Volt since its introduction as a concept vehicle at the 2007 Detroit Auto Show, GM has said that it expects to have the Volt on the road by November 2010.Last November, GM's vice president for product development told a group of automotive journalists that the feasibility of the Chevy Volt plug-in hybrid concept will be proven by next Easter (See: Bob Lutz, the Chevy Volt, and the Easter Bunny). By Easter, Lutz expected the Volt's electric drive system and lithium batteries to be tested for tested their ability achieve 40 miles of gas-free range.However, the company is now putting the battery under 10 years worth of testing in two years to make their 2010 goal. The testing, which involves extreme temperature simulations to expedite processes that would take years longer in the real world, will take place at GM facilities in Warren, Milford, and Mainz-Kastel, Germany.
The Volt is technically a hybrid and contains both an electric and gasoline engine, but is never actually propelled by gasoline. Its electric engine is propelled by lithium ion batteries. The company's next challenge will occur as it works to integrate the battery with a gasoline motor.

Ford Presents: EcoBoost
New Technology Promises Significantly Better Fuel Economy
At the January North American International Auto Show, Ford Motor Company introduced EcoBoost--a new engine technology that it expects to deliver up to 20 percent better fuel economy on half a million Ford, Lincoln and Mercury vehicles annually in North America during the next five years. By using direct injection fuel technology, in which fuel is injected into each cylinder of an engine in small, precise amounts, EcoBoost increases fuel economy and decreases emissions. Coupling direct injection with turbocharging, which compresses the air that goes into an engine to generate more power, allows for smaller engine size and better performance.
The technology was showcased in the Ford Explorer America concept at the 2008 North American International Auto Show in Detroit. It will first appear on the road in the 2009 Lincoln MKS.
More 6-speeds
On April 13, 2008, Ford announced that it would also continue to expand its use of 6-speed transmissions to improve fuel economy. The new Ford F-150 will have a six-speed automatic transmission, as will the soon-to-be-released 2009 Ford Escape and Mercury Mariner. The new transmissions deliver 4 to 6 percent improvement in fuel efficiency on average compared with typical four- and five-speed gearboxes.

GM & Flex Fuel
Automaker invests in cellulosic ethanol and makes more flex-fuel vehicles
Early this year, at the North American International Auto Show, General Motors Corp. announced a partnership with Coskata Inc, a biofuels research company based in Warrenville, Illinois. Neither company has disclosed the details of GM's investment."We are very excited about what this breakthrough will mean to the viability of biofuels and, more importantly, to our ability to reduce dependence on petroleum," GM Chairman and CEO Rick Wagoner said.
GM hopes to make half of its US production flex-fuel capable by 2012. In an effort to provide the infrastructure for these new vehicles, Coskata plans to use proprietary microorganisms and patented bioreactor designs to produce ethanol for under US$1.00 per gallon by 2011. Initial plans involve using wood chips in the process, but the technology could turn practically any renewable resource into ethanol--including grass and garbage.
GM announces new flex-fuel vehicles, incl. 4-cylinder options
GM has also announced that the Buick Lucerne will join its lineup of 15 FlexFuel models to be released in 2009. The Lucerne will be the first flex-fuel capable Buick passenger car on the market. Other models in the lineup include the four-cylinder Chevrolet HHR, the Hummer H2, and H2 SUT.
Alternative Vehicle Sales Up 15%
According to the latest figures from automotive research firm R.L. Polk, sales of alternative fuel (including flex-fuel and hybrid electric) vehicles in the United States increased by 250,000 from 2006, reaching 1.8 million for 2007. Dave McCurdy, president and CEO Alliance of Automobile Manufacturers, attributes this increase to gas prices, consumer incentives, and the increasing number of models. However, McCurdy--like GM executives--is concerned about the need for more stations alternative fuels.
