It seems as if many of the engine-related advancements found in standard General Motors’ vehicles, first came to prominence when implemented in Corvette production, a decade or more prior. One such engine, which could easily be considered revolutionary, is the 2014 6.2-liter LT1. This fearsome powerplant was as sophisticated as it was powerful.
Many consider the Corvette’s seventh generation to be when GM’s iconic car finally came of age. It was during this time that the Corvette made some of its most extensive performance gains on the road and in racing. These performance gains can be attributed to the development in engine technology during the C7’s production run. The Corvette was offered with several available powerplants, all of which were potent.
The LT4 engine has always been synonymous with high-performance. Introduced by General Motors in 1996, the LT4 was specifically designed as a more powerful variant to the next-generation LT1 engine previously introduced by GM in 1992. The LT4 small-block is a modern marvel, packing 600+ horsepower into a compact and affordable package.
At the heart of the ZR1 Corvette resides the supercharged 6.2L LT5. GM’s engineering department was also tasked with producing the ZR1’s engine, which would have to perform at a higher level than that of the Z06’s supercharged LT4 small-block. The 755 HP supercharged LT5 would elevate the Corvette’s performance to a level never before achieved.
