Live up north and want to turn your car on to warm it up before you get in? Live down south and want to get in your car when it has reached a comfortable cooling temperature? Well, OnStar, together with GM, have made this possible by the expansion of their mobile app technology.

Owners of most new 2011 Chevrolet, Cadillac, Buick, and GMC vehicles will have the ability to turn on their car, honk their horns, work their lights, and lock and unlock their doors straight from their smartphone. Gone will be the days when car owners will have to be within a certain distance or even have their keys with them to utilize the capabilities of a traditional vehicle key fob.

These GM brand specific apps will not only provide these vehicle key fob services to you, but they will also provide key diagnostic information right at your fingertips. This information will include fuel tank level and range, remaining oil life, current and recommended tire pressure, and lifetime average miles per gallon. Not satisfied yet? The apps will also be able to provide car owners with current odometer readings, vehicle VINs, and OnStar account numbers right from the phone!

GMC has decided that they will acknowledge the age old saying of "bigger is better" by adding jumbo-sized versions of the already popular Denali HD 2500 series. GMC announced today that the Sierra HD Denali will become available in Denali HD crew cab versions of the 3500 Series (1-ton) for both single rear wheel and dually versions in 2WD and 4WD applications - next to the current 2500 series (3/4 ton), crew cab and 4WD version. Following the success of the 2500 series, additional versions simply had to be created in order to take advantage of the popularity the truck currently has.

The Sierra HD Denali is powered by a Vortec 6.0L gas V-8/six-speed automatic powertrain. For a little more of the green paper, GMC can also provide a new Duramax 6.6 liter turbo diesel V-8 delivering a total of 397 hp at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm. The 0-60 mph sprint will be made in less than 9 seconds and quarter-mile in less than 16 seconds in 2500HD models. The engine is mated to a new Allison 1000 six-speed automatic transmission.

We are all well aware of situation down in Haiti, and while celebrities are holding telethons and individuals are pledging their last dollar to the relief effort, the American automaker General Motors is taking action at the request of the U.N. by sending a fleet of GMC Sierra pick up trucks to the distressed island nation as a joint effort between the GM Foundation and the William J. Clinton Foundation.

According to the former U.S. president, "I?m pleased the GM Foundation has made a generous donation of trucks to our relief efforts in Haiti, which will be instrumental in mobilizing food and lifesaving supplies,...The American auto industry has made great strides to increase aid and assistance to Haiti, and GM?s leadership demonstrates what corporate citizens can do to help the people of Haiti rebuild and recover from the massive earthquake? said Clinton. With the GMC Sierra being one of the hardest working trucks in America, we are sure that they will be right at home being put to work in Haiti.

The American truck builder GMC unveiled the Granite concept, a compact crossover with a unique opening arrangement similar to a German cousin, at the 2010 Detroit Auto Show. The GMC Granite Concept combines the same monolithic stone like design that General Motors brought to market with the full size Terrain, however this time in a smaller streamlined MPV style body. The new concept combines urban industrial design with everyday practicality and is aimed at young time crunched professionals.

If the Granite becomes a production vehicle, it will become the smallest GMC ever. Powered by a boosted 1.4 Liter four cylinder engine and gas sipping six speed transmission, the turbocharged mini truck would make for a very efficient, practical and stylish mode of urban commuting. The exterior of the Granite features an over sized version of GMC?s signature grill with a pair of vertical LED headlamps that trail back into either fender and dare we say R8 inspired vents underneath. Add in an interior that is easy on the eyes, a brushed metal tip sticking out the center of the back bumper and cap it off with a 20 inch set of wheels and you get one bad little GMC truck.
