GM Omega Vehicle Platform

Omega is the name of a General Motors vehicle architecture engineered to underpin full-size, rear-wheel-drive luxury vehicles.

Omega was first utilized on the Cadillac CT6 — the flagship of the Cadillac model range that competes with full-size luxury flagship sedans such as the BMW 7 Series, Mercedes-Benz S-Class, Audi AS/S8, and Lexus LS. To note, the 2016 Cadillac CT6 was originally going to be called LTS.

Omega platform features include:

  • Rear-wheel drive standard with support for all-wheel drive
  • Longitudinal engine placement
  • Lightweight due to use of advanced materials such as aluminum and magnesium
  • World-class, agile yet comfortable driving dynamics
  • Perfect 50-50 weight distribution
