Earlier this week, GM Authority Editor in Chief Manoli Katakis made a peculiar observation that’s worth sharing with GM fans the world over. Specifically, it’s that GM’s latest iteration of the Gamma vehicle architecture is the automaker’s first modern platform to serve as the basis of both cars and crossovers.
Traditionally, cars and crossovers rode on significantly different platforms; take, for example, the Epsilon architecture underpinning the Chevy Malibu, Buick Regal, and Opel Insignia and compare it to the Theta platform that serves as the basis for the Chevy Equinox and GMC Terrain. These vehicles, which squarely fit in the midsize category, rode on disparately different architectures. Interestingly, General Motors started with its smallest platform — the Gamma — in merging the traditionally separate platforms for CUVs and sedans, hatchbacks, or wagons. In effect, GM’s second-generation Chevy Aveo/Sonic sedan and hatch as well as the new Trax crossover (along with the Buick Encore/Opel Mokka CUV) — all of which ride on the Gamma architecture — serve as proof of this development.
To us, this means that the decision to unify subcompact CUVs and subcompact cars on a common Gamma architecture preceded the idea of doing the same with other platforms — such as with the successor to the Delta, the D2 — for instance. Whatever the case may be with GM’s timing in deciding to base both crossovers and cars on a common Gamma chassis, the determination falls well in line with GM’s goal to cut the amount of individual platforms it uses by the year by 2018 — all in an effort to decrease complexity and increase profitability.Google+
