GM Debuts the 2015 Chevrolet Silverado HD and GMC Sierra HD
First and foremost, the 2015 Chevrolet Silverado HD and 2015 GMC Sierra HD 2500 and 3500 all receive the same substantial facelifts as the half ton brethren of these new heavy haulers. Aside from the obvious fact that the 2500 and 3500 versions of the new Silverado and Sierra are quite a bit larger than the 1500 versions, the heavy duty Chevrolet and GMC pickups look very similar to the light duty models that were introduced earlier this year. Within each of the brands, the 1500, 2500 and 3500 share a very similar “face” with the Silverado relying on a stacked headlight design while the Sierra HD calls upon a similar projection designed accompanied by a row of LEDs for a high end, high tech look. The biggest difference is that the heavy duty versions of the revamped Chevy and GMC trucks is a larger grille on each of the two trucks to allow for better engine cooling under the rigors of heavy duty truck work.
"It is one thing to generate big power numbers in cool weather, and quite another to maintain power and torque when towing up a long grade on a blistering summer day," said Luke. "We think customers will appreciate all of the work that went into the cooling for the new Silverado HD when they get a chance to really put it to the test."
