Chrysler laid out most of its future plans earlier today, revealing information about a score of upcoming models and technologies including new dual-clutch transmissions, a hybrid Dodge Ram, a fuel-efficient AWD system and a Nissan-sourced small hatch just to name a few, but it isn’t the only U.S. automaker with major updates planned for the 2009 model year. GM has also come out with a number of major announcements today covering most of its brands.

GM will finally make Bluetooth hands-free phone integration available on nearly all of its cars and trucks - currently only the Cadillac STS offers the technology. The General will also replace many of its older four-speed automatic transmissions with new smooth-shifting six-speed units, becoming either standard or optional on vehicles like the Chevrolet Avalanche, Silverado and Suburban and GMC Sierra 1500, Yukon and Yukon XL – the Tahoe, however, will stick with the older four-speed unit. Other cars getting the new six-speed auto include the Pontiac G6 (pictured) as well as a new four-cylinder Chevrolet Malibu LTZ.

Other major changes include the introduction of a 290hp version of GM’s 3.6L V6 engine in the GMC Acadia and Saturn Outlook. The engine debuted in the new Chevrolet Traverse crossover but there are no plans to bump the output of that model from its current 286hp level and there’s no confirmation whether the Buick Enclave will also receive the engine upgrade.
