What Does LS Mean on a Car?

December 4, 2023

If you’re in the market for a new vehicle, there are lots of things to consider. From the interior design to the engine type, the vehicle you choose can have a huge impact on your driving experience. That’s why it’s so important to do your research before buying a new car.

One of the most important features is the power. If you’re looking for a fast and powerful vehicle, an LS engine is a great choice. The LS engine series is a V8 engine that was implemented by GM’s line of rear-wheel drive cars and trucks. It made its debut in 1997 and is sometimes referred to as the Gen III Small-Block. This new engine is designed to improve performance and meet CAFE (corporate average fuel economy) standards.

The LS1 (5.7 liter, 346ci) was the first of these new engines and it debuted in the 1997 Corvette and 1998 Camaro. It was a big departure from the previous LT1 (Gen II) engine and featured a deeper-skirt aluminum block with a coil-near-plug ignition. These new engines were also more lightweight, making them a better choice for the truck and SUV applications that would use them.

The LS4 (5.3 liter, 327ci) is a popular version of the LS engine for truck and SUV applications. It used a larger iron block and was rated at 303 horsepower. It can be found in some front-wheel drive Pontiac Grand Prix GXPs and Chevrolet Impalas.
