Specifications
The LS9 engine is a high-performance, track-focused V8 engine developed by General Motors for elite racing applications. Designed as a more extreme counterpart to the celebrated LS series, the LS9 exemplifies the pinnacle of GM’s engineering delivering massive power, exceptional durability, and world-class forced-induction performance straight from the factory. Built on the legendary LS architecture, the LS9 elevates the formula with a supercharged 6.2-liter (376ci) V8, precision-forged components, and a calibration tailored for incredible throttle response and top-end power. It became best known for powering the C6 Corvette ZR1, transforming it into one of the most formidable American supercars ever produced.
LS9 engine variants generally refer to the LS9 itself GM’s high-output, supercharged V8 and its closely related counterpart, the LSA. Both are supercharged engines, with the LS9 offering the highest performance and originally engineered for the Corvette ZR1. The LSA delivers slightly lower output and was fitted in other performance-focused GM models. While the LS3 is the base architecture for the LS9, the LS7 is a separate naturally aspirated engine and not considered a direct variant of the LS9.
