As an automobile manufacturer, General Motors is well aware of the building blocks to production success - lesser vehicle platforms than before. In addition to that, GM higher-ups also know that to be competitive in this day and age, they need to offer the neatest platform technologies currently available without increasing production costs.
GM Delta platform (aka Global Compact Vehicle architecture)
- Description: this compact front-wheel drive car and crossover SUV platform debuted on the 2003 Saturn Ion. It replaces the old-school platforms like the GM T, GM J and the GM Z platform of the Saturn S-Series.
GM Theta platform
- Description: introduced in 2002 for compact/mid-size crossover SUVs. What is known as the GM Theta Premium is a variant of the platform that was used by the 2010 - 2015 model year Cadillac SRX and the 2001 Saab 9-4x compact luxury crossover SUV.
GM D2XX/D2UX platform
- Description: this is where it gets interesting. The GM D2XX/D2UX architecture replaces the GM Delta II. It was introduced in August 2012, and it allegedly cost $220 million to be developed. This metal skeleton is also replacing the crossover-only GM Theta platform.
GM Alpha platform
- Description: put simply, the GM Alpha platform was developed to replace the old as socks GM Sigma. It was reportedly engineered to be as light as possible in order to deliver “world-class driving dynamics.”
GM Epsilon platform
- Description: from 2002 to this day, the GM Epsilon played the role of compact, mid-size and large car platform for the Detroit-based manufacturer. Certain reports suggest that Opel developed it in Germany.
GM E2XX platform
- Description: currently under development, the E2XX will replace the GM Epsilon II architecture. The GM Lambda platform will be phased out in favor of the GM C1XX (Chi) platform, believed to be derived from the E2XX. The 2016 Chevrolet Malibu (and next-gen Opel/Vauxhall Insignia) are underpinned by the E2XX.
GM P2XX platform
The longer variant of the GM E2XX is believed to be the backbone of the 2016 Buick LaCrosse, as well as the next-gen Chevrolet Impala full-size sedan.
GM C1XX platform
In a nutshell, the C1XX is believed to be the mid-size and full-size crossover architecture derived from the GM E2XX.
GM Omega platform
- Description: Introduced at the 2015 New York Auto Show on the 2016 Cadillac CT6 full-size luxobarge, some voices claim that the GM Omega platform is an extension of the GM Alpha platform. The platform is modular enough to be adapted for full-size SUVs.
