The Toyota N platform is a car platform for executive cars (E-class models) from Toyota, introduced in 2003. It is often called "Mark X platform" and "Crown platform", after its core uses, and, less frequently, "Lexus GS platform". It is used on a variety of sizes of rear- and all-wheel drive automobiles, ranging from compact to full-sized executive. In 2018, the N platform was replaced by the Toyota New Global Architecture TNGA-L platform.
