GM Lambda platform
Lambda vehicles feature easily accessible three-row seating.  They were supplied with the LY7 3.6-liter V6.  Starting with the 2009 model year all Lambda vehicles have GM LLT 3.6-liter gasoline direct injection engine for improved fuel efficiency, horsepower and torque. It is unlikely GM will offer a V8 engine for Lambda. The platform has been designed for front and all-wheel drive applications. Lambda is expected to be replaced by the new GM C1XX platform.
