LTZ - an abbreviation of Luxury Touring Z - is one of Chevy's higher trim levels, only applied to their pricier, and upmarket models. Since it's one of the higher-end trims, a Chevy vehicle fitted with the LTZ trim adds more features as standard. For the most part, you're getting more luxury appointments and in-car technology, as well as more safety systems and updated driver aids. Therefore, you can expect more equipment, accessories, and upscale touches with the LTZ trim compared to the LT or LS trim levels. In specific Chevy models, the LTZ also unlocks other features that the other trim levels don't get, such as beefier engines and more potent performance.
