There is no official LS V10. GM’s LS family consists of V8 engines, and no production V10 variant has been released within that lineup. This article explains what the LS family is and why a V10 version does not exist, along with the options enthusiasts consider for higher-cylinder power within GM's offerings.
Understanding the GM LS engine family
The LS family is GM’s modern small-block V8 line, introduced in the late 1990s and used across a wide range of cars and trucks, including Corvette, Camaro, and various GM SUVs and trucks. Typical features include a 90-degree V8 configuration, pushrod valvetrain, and a mix of aluminum and iron blocks depending on the model. Displacements have ranged roughly from about 4.8 to 7.0 liters in production applications, with several high-performance variants used in performance-oriented models and crate engines.
Why there isn’t a V10 variant in the LS family
The LS architecture is optimized for a V8 layout, prioritizing packaging, weight distribution, and consumer demand for eight-cylinder power in a relatively compact package. Adding two more cylinders to form a V10 would require a substantially different crankshaft arrangement, bearings, exhaust routing, and overall chassis integration, diminishing the efficiencies that define the LS platform. There have been no GM- or GM Performance-catalogued production LS V10 engines, and no official LS V10 variants have been released to the market.
What options exist for higher-cylinder power within GM offerings
For buyers seeking greater power or a higher-cylinder configuration, GM’s current mainstream approach remains focused on the various V8 LS engines, frequently enhanced through performance variants, forced induction, and crate engines rather than moving to a V10 within the LS line. Enthusiasts seeking even more displacement or cylinder count typically look to non-LS GM engines or aftermarket/custom solutions, all of which are outside the standard LS lineup.
Summary
In short, no official GM LS engine is a V10. The LS family comprises V8 powerplants, and GM has not released a production V10 variant within that lineage. For more power within GM’s modern offerings, the path remains high-performance LS V8s and related crate or aftermarket options rather than a V10 in the LS family.
