The LS3 engine is one of the most well-known and highly regarded powertrains in the automotive world, especially among enthusiasts of American muscle cars. Whether you're considering purchasing a car with an LS3 engine or just curious about its capabilities, understanding which vehicles were equipped with this powerhouse is essential. In this article, we’ll explore what makes the LS3 engine so special, which cars came with it, and why it's a popular choice for performance vehicles.
The LS3 Engine is a 6.2-liter V8 engine that was introduced by General Motors as part of its Gen IV small-block engine family. First appearing in 2008, the LS3 engine was designed to provide a significant performance upgrade over its predecessor, the LS2. With its increased displacement and refined design, it delivers higher horsepower and torque, making it a popular choice for performance-oriented cars.
In stock form, the LS3 produces around 430 horsepower and 424 lb-ft of torque. This engine features an aluminum block and aluminum heads, helping to reduce weight while maintaining strength. Its high-revving nature, paired with its powerful performance, made it a top contender in the American muscle car scene, and it quickly became a standard for GM’s sports models.
The LS3 is known for its versatility, reliability, and tuning potential. It has become a favorite not only in factory-built cars but also for those looking to swap out engines in project cars, making it an iconic engine for both factory and aftermarket applications.
Several high-performance cars have been equipped with the LS3 engine over the years. Here are some of the most notable vehicles that featured the LS3 under their hoods:
The Chevrolet Corvette is perhaps the most iconic car to feature the LS3 engine. From 2008 to 2013, the Corvette C6 was powered by this V8 engine. The Corvette was always known for its performance, and the addition of the LS3 engine provided even more power, helping it maintain its reputation as a world-class sports car. With its 430 horsepower and 424 lb-ft of torque, the C6 Corvette could accelerate from 0 to 60 mph in just under four seconds.
The Chevrolet Camaro SS, particularly from 2010 onward, also comes with the LS3 engine. The fifth-generation Camaro SS, reviving the classic muscle car nameplate, uses the LS3 to produce 426 horsepower and 420 lb-ft of torque in the manual transmission version. This performance boost allowed the Camaro to compete with other American muscle cars and even surpass its competitors in terms of raw power.
The Chevrolet SS Sedan, which was available from 2014 to 2017, was another performance vehicle that used the LS3 engine. This full-sized, rear-wheel-drive sedan offered the power of a sports car with the practicality of a family sedan. With 415 horsepower, the SS Sedan was a sleeper hit, delivering excellent acceleration and handling performance.
The Pontiac G8 GXP was a high-performance variant of the G8 sedan. Released in 2008, the GXP version of the G8 featured the LS3 engine, producing 415 horsepower and 400 lb-ft of torque. Though production was limited, the G8 GXP remains a highly regarded performance car for collectors and enthusiasts, offering exceptional performance for its class.
In markets like Australia, the Holden Commodore SS used the LS3 engine, delivering similar performance to its American counterparts. The Holden Commodore SS was a performance sedan with the power of the LS3, making it one of the most popular sports sedans in Australia before it was discontinued in 2017.
In addition to the models listed above, the LS3 engine was also used in several other GM vehicles, including some versions of the Chevrolet TrailBlazer SS and Chevrolet Silverado trucks. Additionally, various aftermarket companies and performance tuners have swapped LS3 engines into other vehicles, creating custom builds that cater to performance enthusiasts.
