While General Motors has drastically improved its lineup over the past several years, there still have been some pretty glaring holes. But come the 2009 model, GM will patch some of those holes and bring its lineup up to snuff.

As shocking as it sounds, the Cadillac STS has been the only GM model to offer Bluetooth hands-free phone integration -- a feature that is at least optional on the majority of cars in the marketplace. But for 2009, GM will begin offering Bluetooth on several of its models.

Most of GM's vehicles will also step into the modern era by ditching their four-speed transmissions in favor of six-speed gearboxes. GM's GMT900-based vehicles will be making the biggest moves -- with the Chevrolet Avalanche, Silverado and Suburban and GMC Sierra 1500, Yukon and Yukon XL having a six-speed as standard or optional equipment -- although for some reason the Chevrolet Tahoe will continue on with its four-speed transmission.

The Pontiac G6 will also see a six-speed, as will the the four-cylinder LTZ Chevrolet Malibu.

And, as predicted, the GMC Acadia and Saturn Outlook will get a direct-injection version of GM's 3.6L V6 rated at 290 horsepower. That powerplant made its Lambda debut in the Chevrolet Traverse at the Chicago Auto Show, but in Traverse guise is produces between 281 and 286 horsepower. No word if the Buick Enclave will also receive the engine upgrade, but it would seem like a logical assumption.
