GM has filed to trademark LTX for the fourth time in the last ten years for potential use on a future V8 crate engine product family, GM Authority has uncovered.
Filed on April 11th, 2022 with the United States Patent and Trademark Office (USPTO), the application is assigned serial number 97355682. The application was filed under a Goods and Services category reserved for “Engines for automobiles, sport utility vehicles, trucks and vans.” GM filed a similar LTX trademark application in 2013 in the United States and Australia, and filed it a second time with the USPTO in 2016. It also filed an LTX trademark application in Canada in 2019.
The LTX name could be used for a new V8 crate engine family from Chevrolet Performance – perhaps one that will replace the current LSX family. The LSX is a high-performance crate engine family that features a cast-iron block with additional material in certain areas, making them well-suited to high-horsepower builds. The current LSX crate engine lineup sold by Chevrolet Performance is based on the Gen IV Small Block engine family, which includes the 6.2L LS3 V8, so it seems likely the LTX engine lineup will fill a similar role, but will be more closely related to Gen V Small Block motors like the 6.2L LT1 V8.

There are many differences between the LS and LT engine families in production form. The LT engines feature improved variable valve timing, high-pressure direct injection, a different oiling system with eight injectors that spray the bottom of the pistons, repositioned intake and exhaust valves as well as larger diameter cylinder head bolts, among more. The design of the engine offers multiple improvements in production vehicles, so it will be interesting to see how these changes carry over into an LT-based performance crate engine.
GM sells the Gen 4-based LSX crate engine in two displacements, 376 cubic inches (6.16 liters) and 454 cubic inches (7.4 liters). The LS376 is rated at 476 horsepower and 444 pound-feet of torque, while the LSX454 is rated at 627 horsepower and 586 pound-feet of torque.
