According to our data, the full-size pickup segment declined by 29.4 percent last year. Of all full-sized pickups, the Chevy Silverado lost the most volume, dropping 32 percent and an eye-popping 148,521 units compared to 2008. GMC Sierra dropped 33.6 percent, or about 56k units. Overall, GM shed half a million pickup sales last year, as its total truck sales fell to 1.2 million. When you’re losing that kind of volume in a shrinking segment, you know it’s time for a hold-em-or-fold-em moment. According to the Detroit News, GM is doubling down on its full-sized truck ambitions, allocating “several hundred million” of your tax dollars towards a re-working of the GMT 900-based trucks.
