E2 is the name of a General Motors vehicle architecture designed to underpin midsize and full-size vehicles. It succeeds the Epsilon 2 architecture and represents a “fork” in the Epsilon 2 platform, with top priorities behind E2 being decreased vehicle weight and increased vehicle size, world-class safety, technologies, and driving dynamics.
The E2 platform is believed to have served as the basis for the C1 platform that underpins larger crossovers/CUVs.
Vehicles built on the E2 platform carry internal project codes E2XX, with the trailing Xs denoting brand and vehicle type. As such, the E2 platform is sometimes referred to as E2XX.
