Freescale Chips On Chevy, GMC Hybrids

By Anthony Fontanelle

General Motor Corp. in partnership with Freescale Semiconductor Corp. will be promoting improved fuel efficiency by using innovative chips. Freescale chips will be used in Chevy and GMC hybrids to pave the way for a green makeover.

According to reports, Freescale chips that control the combustion and electric engines as well as the transmission in the new Chevy Tahoe and GMC Yukon hybrids have produced a 50 percent increase in mileage over their counterparts. The hybrids are efficient for both city and highway. To note, they can tow a 6,000-pound cabin cruiser. The hybrids are now arriving at Valley Chevy and GMC dealerships.

John Hartley, Internet sales manager at Midway Pontiac GMC in Phoenix, said there is considerable interest in the vehicles. However, the production of the hybrid sport utilities is currently limited.

The increase in fuel efficiency is attributed to the automaker’s two-mode hybrid transmission that is operated by Freescale’s advanced microcontroller technology.

"The automotive industry is a very significant part of Freescale's business," said Tony Massimini, an analyst with research company Semico Research Corp. "And the hybrid market is becoming very important part of the U.S. car business."

The Austin, Texas-based supplier of microcontrollers found in American cars, is determined to improve the offers of automakers in the industry. And its cutting-edge products are expected to make it happen.

Kevin Klein, vice president of marketing for Freescale's automotive group, said that a current luxury car can contain over 100 chips that control everything from disc brakes to parking-assistance radar. He added that automotive chip sales now amount to about a third of Freescale's $5.7 billion in annual revenue.

The innovative technology offers two driving modes. Using the first driving mode, the vehicle can operate at low speed and with light loads in three ways: electric power only, engine power only or in any combination of engine and electric power, reported The Arizona Republic. The second mode, meanwhile, is used primarily at highway speeds. This mode provides full eight-cylinder engine power when road conditions require. It can be employed when passing other vehicles, climbing a steep grade or pulling a trailer. Additionally, a refined control unit settles which mode the vehicle should use.

"With the introduction of the world's first full-size hybrid SUVs, GM is pioneering a niche in the automotive market that's in step with today's growing concerns about the environment and global warming," said Paul Grimme, senior vice president and general manager of Freescale's Microcontroller Solutions Group. "We're proud that Freescale technology is helping make these innovative, fuel-efficient SUVs a reality in the market."

General Motors Reports Progress Toward New All-Electric Car

By John Birchard/Voice of America

In January of 2007, General Motors (GM) unveiled a concept car powered solely by electricity. The Chevrolet Volt is a big step beyond today's hybrid, that uses both a gasoline engine and electric motor. VOA's John Birchard reports on the progress GM is making toward turning the Volt from an attractive idea into a production vehicle.

As vice president of research and development and strategic planning for General Motors, Larry Burns is responsible for the company's efforts to reinvent the automobile, so to speak - to move beyond conventional gasoline-powered vehicles to environmentally sound "green" cars of tomorrow.

The seemingly routine news of GM's recent award of two contracts to suppliers who will conduct advanced battery development for the Chevrolet Volt is, according to Burns, really a milestone for the company. Because the battery that powers the Volt is the key to its existence.

"Specifically, what you can do is plug your car into a regular 110-volt outlet at night and, over a four to six-hour period, recharge the battery so that the next day you can drive this car 40 miles [64 kilometers] on pure electric drive with no emissions."

At the suggestion that forty miles, 64 kilometers, doesn't sound like a long distance, Larry Burns cited research that indicates the projected range of the Volt would meet most Americans' requirements.

"Because 70 percent of the people in the U.S. travel less than 40 miles a day. For a lot of people this kind of vehicle could meet most all of their travel needs on pure battery electric driving," he said.

Americans are accustomed to hearing automakers talk about the car of tomorrow... about hydrogen power and fuel cells being the wave of the future. But it always seems to be the next decade, or beyond, before these marvelous pollution-free vehicles will arrive. So, we asked the GM executive when will the all-electric Chevrolet Volt be in a dealer's showroom, ready for sale to the public? His answer?

"Since we started our production engineering in January of this year and, typically, the lead times in the auto industry are three to four years, that would suggest we ought to have it out in that time frame. But we haven't formally announced that date, just because there's still a lot of work to be done on the battery and we want to make sure we get that work done properly," he said.

Storage of electricity has long been a vexing problem for automakers. The battery that is big enough to store sufficient power to not only move the car, but operate all the electrical devices that modern cars require is currently too big to carry in the car and still have room for people and cargo. So, the contracts General Motors awarded to those suppliers recently amount to a crucial component for GM's non-polluting future fleet.

GM Europe launches Environment Initiative

By Iver Penn

General Motors Corp.'s European division announced an affirmation on Friday regarding making its model line more environmentally friendly. The division said that it would put cleaner engines in conventional cars, offer more cars that can use ethanol and move ahead with fuel cell technology.

Company officials said at a news conference in Berlin that the company dubbed the program ecoFLEX and it would offer an ecoFLEX version with lower emissions in each model line, starting with the 2008 Corsa 1.3 CDTI compact from its European Opel brand.

The car will emit only 119 grams per kilogram of carbon dioxide, a figure that is below the proposed EU average standard of 130 grams per kilogram. According to the officials, one key to the new models was that the company aimed to have them driven the same and cost the same as the more conventional vehicles they are based on.

Saab, a Swedish brand, would also expand its range of biofuel engines. Even luxury brand Cadillac will offer a model with an E85 biofuel engine by fall 2007. E85 is a term used for motor fuel blends of up to 85 percent ethanol — an alcohol that can be derived from plants — and just 15 percent gasoline.

Vice Chairman Bob Lutz of General Motors said that the program offers ways to trim down CO2 emissions quickly. He said that E85 has a very strong potential to significantly minimize CO2 from passenger cars in the near term. He added that a pan-European policy is required to make the necessary fuels widely available and reflect the lower CO2 emissions in vehicle taxation.

GM officials said that they would tackle environmental concerns with several technologies instead of just focusing on just one. They continued that they were moving ahead "flat-out" on developing vehicles that run on hydrogen fuel cells, while other technologies could simply enhance the environmental performance of existing internal combustion engines.

One example was the Eco-Turbo engines that make use of smaller cylinder displacements but yield equivalent power and efficiency through turbo charging.

The company claimed that it would develop 16 new GM Europe engine families and 10 new transmission families by 2012.
