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 GMC Granite Concept combines the same monolithic stone like design that General Motors brought to market with the full sizeTerrain , 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.

Top Speed had the pleasure of trying out a greener option for that other necessary item in any weekend racers garage, a work truck. Sure its nice to have a classic Ferrari or a an all out race car in your garage, but what good are they if you cannot get them to an appropriate environment. That is where our GMC Sierra 2WD Hybrid Crew Cab comes into play, this pick up can haul up to 6,100 pounds of trailer and seat six individuals inside the cab. Aside from the nice touches like the 18 inch chrome rims and larger than life front grill, the Sierra Hybrid has the benefit of being an alternatively fueled vehicle.

The full sized trucks 2-Mode Hybrid/Electric power train is tuned to get as much as 21 MPH when driving around town, impressive for any vehicle that weighs over 5,000 pounds. Don’t let the size discourage you, the Sierra Hybrid is easy to drive and the power adjustable front seat allows the driver to find the perfect vantage point.

The truck uses a combination of an electric module and a 6.0 Liter Chevrolet small block to make 332 HP, but you most likely won’t have to use much of those ponies, we found ourselves driving the Sierra around on electric only power most of the time, negating the need for any of the eight pistons. It was nice to know that they were there when we needed them like when passing on the highway or pulling a heavy load. One thing was for certain, the GMC Sierra Hybrid is working hard to give trucks a good name again.
