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.
