Safety scores for all kinds of new vehicles have been shifting since last year. That's when the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) both changed the way they crash-test vehicles and how they calculate the end results.
With the Silverado, the crash tests don't give a complete picture of safety, but they do produce some data for all three body styles. The IIHS says the Silverado is a "good" performer in frontal impacts, without specifying a body styles. However, they also find the side-impact protection to be only "acceptable," and roof strength "marginal."
The NHTSA, on the other hand, rates all body styles at four stars overall, including a five-star rating for side-impact protection.Side and side curtain airbags are standard on all Silverado 1500 models, while anti-lock brakes, stability and traction control, OnStar, and tire pressure monitors are all included. A rearview camera is available, as are power-adjustable pedals.
