GM confirms direct injection for next-gen small-block V8
While output and economy numbers will have to wait, General Motors has confirmed that the upcoming fifth generation of its iconic small-block V8 engine family will be fitted with an advanced direct fuel injection system. That upgrade, combined with a significantly higher compression ratio and several other innovative technologies, will play a critical role in helping GM meet ever more demanding CAFE requirements while still delivering the kind of overall performance buyers have come to expect from this iconic powerplant. Beyond releasing a photo of the multi-orifice fuel injector that will be used to feed this new-iteration small-block, the only hard fact that we know at the moment is that the engine will retain the same historic 4.4-inch bore-center dimension that has remained a constant throughout its 56-year history.
"The Gen-V small block is an all-new, state-of-the-art engine family that will offer more efficiency and refinement than any other small block in its more than half-century of production," said Jordan Lee, chief engineer. "For customers, that will mean cars and trucks that deliver more while using less gas to do it." Last month, the existing GM small block reached a mind-boggling milestone of its own when the 100,000,000th example -- a 638-horsepower supercharged LS9 variant -- rolled off of the production line at GM's Performance Build Center at Wixom, Michigan.
