"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."¯
GM has yet to release full details on its Gen-V engine family, but it is believed the unit destined for the Chevrolet Corvette will displace 5.5L. Although smaller than the Vette's current 6.2L Gen-IV V8, the new mill is expected to match or exceed the car's 430 horsepower rating.
GM has already committed $1 billion to build the next-generation engine family, with that investment expected to create or retain 1,711 jobs. However, the Detroit automaker isn't committing to a solid launch date, saying only that the "Gen-V small block will go into production in the near future."¯
