We don't normally cover every little change an automaker makes to its lineup as the model year clicks over, but General Motors has some significant features it's adding for 2009 that shouldn't fall through the cracks. For one, Bluetooth will finally become available on nearly all of GM's cars and trucks. For the longest time, only the Cadillac STS was available with Bluetooth phone integration, which ends with MY2009. Second, the six-speed automatic transmission that before was not widely available in the General's half-ton trucks and SUVs has spread like wildfire across the GMT900 lineup and will now be standard or optional in such vehicles as the Avalanche, Silverado and Sierra 1500, Suburban, Yukon and Yukon XL. Curiously, though, it's still not available on the Tahoe.

Other items of note include a new 6-speed automatic for the Pontiac G6 to replace its underwhelming 4-speed, the replacement of GM's 3.6L V6 in the GMC Acadia and Saturn Outlook with the direct-inject version that will bump power up to 290 hp, and finally a new four-cylinder base model for the uplevel Malibu LTZ that features the the 2.4L four-cylinder ECOTEC engine paired with a six-speed automatic. Thanks for the tip, Cameron!
