    افتراضي هل ستطلب تويوتا ونيسان مساعدة GM ؟؟؟


    خلاصة الموضوع ان تويوتا ونيسان ربما يستخدموا محركات GM الديزل في سياراتهم



    In its 50-year history in the US, Toyota has never sourced an engine for its vehicles from an outside supplier. There is a possibility that this may change if Toyota decides to put a diesel in its new Tundra full-size pickup truck. While we think it's more likely for Toyota to leverage its Hino commercial truck division, it could decide to pick from many of the U.S. diesel engine manufacturers that are developing smaller displacement diesels for Ford, GM, and Dodge. Nissan is also courting a U.S. manufacturer to supply a V8 diesel for its Titan pickup (although Nissan also has it's own diesel manufacturing capability). No one seems to be mentioning Isuzu as a possible supplier, as it has extensive experience with diesels, both large and small (it is currently suppling the DuraMax diesel used by GM).

    Regardless, Toyota sees through its cloud of hybrid hype to realize that truck buyers may actually want an oil-burning engine, perhaps more so than a pack of batteries and an electric motor. The domestics have finally gotten the hint that if they're going to continue to sell full-size trucks, they need to team up their body-on-frame bread-and-butter with a high-tech low displacement diesel to get all the fuel economy they can. Now Toyota is looking to go down that path, and it will be interesting to see whether it chooses to develop an engine in-house or go outside to another supplier.

    Diesel Engine Puts GM In The Fast Lane

    Diesel Engine Puts GM In The Fast Lane

    By Clanton, The News


    Published on 9/16/2006 in Wheels » Wheels National


    Milford, Mich. — General Motors Corp. one-upped rivals recently by revealing plans to offer a fuel-efficient diesel engine for its full-size pickups within three years, a move that competitors in the cutthroat pickup market may be forced to match if gas prices continue to rise.
    GM said its new V-8 turbo-diesel will be 25 percent more fuel-efficient than a comparable gasoline engine and hinted the motor also could wind up in a range of vehicles besides pickups. But the engine won't be on the market until after 2009, GM said.

    During a media briefing Thursday at GM's Milford Proving Grounds, company officials stressed the importance of diesel engines as part of a broad strategy to address growing consumer anxiety over high fuel prices.

    But they stopped short of saying how big a role diesel will play for GM in North America, where demand for diesels remains very small in non-commercial vehicles such as cars and SUVs.

    “At this point, we're not talking about anything but trucks,” said Charles Freese, GM's executive director of diesel engineering.

    GM's announcement underscores the pressure automakers are under to develop more fuel-efficient cars and trucks as gas prices hover around $3 a gallon, and it could give a boost to diesel engines as an alternative to traditional gas engines.

    More than half of European drivers opt for diesel engines, but many Americans think diesels are still as loud and dirty as those they remember from the 1970s and 1980s.

    Today, sales of diesel engines in mainstream car and truck models represent less than 1 percent of the 17 million vehicles sold in the United States each year.

    But that could change if gas prices continue to soar and automakers keep making advances in diesel engines, said Casey Selecman, a powertrain analyst at CSM Worldwide in Northville, Mich. The firm predicts diesel sales could rise to 5 percent or more of the market by 2010 if gas prices remain at current levels.

    GM said the new V-8 is expected to be best in its class for power and towing and will exceed stricter federal regulations on diesel emissions that take effect in 2010.

    GM leapfrogged new diesel standards that kick in next year, and sought to comply with guidelines that will allow it to be sold in all 50 states. Today, California and some New England states have adopted diesel emissions laws that are more stringent than those of the federal government and bar diesels from being sold that do not comply.

    Other automakers are also working to have cleaner diesels for non-commercial or “light-duty” pickups on the market by 2009 or 2010, Selecman said. But GM is the first to release details of a specific engine under development.

    Ford Motor Co., which produces the best-selling F-Series pickup, may not be far behind. “Our aim is to maintain leadership in the truck market,” said Ford spokesman Nick Twork, who would not comment on future product plans.

    DaimlerChrysler AG's Chrysler Group has been a champion of diesel technology, even as gasoline-electric hybrids gained popularity. The automaker dropped a diesel in its Jeep Liberty SUV last year, and has plans to release a diesel-powered Jeep Grand Cherokee for the 2007 model year. But the company has not announced plans for a diesel in its mainstream Ram pickups.

    In addition to pickups, GM said the new diesel is compact enough to fit in vehicles that now carry its “small-block” V-8. That list includes the Cadillac CTS-V, Chevrolet Impala and Pontiac Grand Prix sedans.

    Also Thursday, GM shared details of an updated diesel engine for its heavy-duty pickups that complies with the stricter federal emissions laws taking effect next year. The 2007 6.6-liter Duramax diesel will be available early next year and boasts a 90 percent reduction in emissions of black, smoky particulate matter and a 50 percent cut in smog-forming NOx.

    The announcement comes just days after Ford said it will have a new clean diesel for its 2008 F-Series Super-Duty pickup line.

    تويوتا ناويه تعتمد على شركات خارجية متخصصه بمحركات الديزل ، وهي نفس الشركه اللي تستخدمها
    جنرال موتورز وفورد ودودج في محركاتها ..

    هذا على حسب فهمي للموضوع :)
