One of the most conspicuous absences from GM’s full-size truck reveal was the lack of any hybrid variants. The highly-touted but slow selling hybrid full-size trucks and SUVs were never intended to be the darlings of America’s truck space, but they played an important behind the scenes role for the company.
A hybrid truck may have been as appealing to the average truck buyer as a camouflage tutu, but under the arcane CAFE rules, there were plenty of credits to be had by producing a hybrid truck or large SUV. For the nitty gritty details, a longer summary is available here. For those with an aversion to long, complex explanations of government regulations, let’s just say that the “credits” applied to every hybrid truck or large SUV produced would help a given auto maker reach its CAFE target, because the credits can not only be applied to the trucks themselves, but to other “underperforming vehicles” – or retained for use in later years.
But with GM cutting its R&D budgets, the “two-mode hybrid” system is set to die. In its place is a new Gen V small-block V8 with direct injection, variable valve timing and cylinder-deactivation. Final fuel economy numbers aren’t available yet, but we do know that GM is going at it alone with their “two truck” strategy, offering the large trucks alongside a smaller pickup with superior fuel economy. Unlike Ford and Chrysler, the V6 Silverado/Sierra won’t play such an important role for the General.
