'''Lambda''' is [[General Motors]] [[full-size]] or [[mid-size]] 3-row [[crossover SUV]] [[automobile platform]].  It is largely derived from the [[GM Epsilon platform]], which underlies the [[Chevrolet Malibu]] sedan and similar models.

The [[Buick Enclave]] [[concept car]] was previewed at the 2006 [[North American International Auto Show]], and the [[Saturn Outlook]] was shown at the 2006 [[New York Auto Show]]. The 2007 Outlook and [[GMC Acadia]] went into production in late 2006, followed by the 2008 [[Buick Enclave|Enclave]] in mid-2007, and the 2009 [[Chevrolet Traverse]] in mid-2008.

Lambda vehicles feature easily accessible three-row seating.  They were supplied with the [[GM High Feature engine#LY7|LY7]] 3.6-liter [[V6]].  Starting with the 2009 model year all Lambda vehicles have [[GM High Feature engine#LLT|GM LLT]] 3.6-liter [[gasoline direct injection]] engine for improved [[fuel efficiency]], horsepower and torque.  With the cancellation of GM's [[GM Ultra Engine|next-generation]] [[DOHC]] [[V8 engine|V8]], there would be no V8 powertrain for the Lambda platform. The platform has been designed for [[front-wheel drive|front]] and [[all-wheel drive]] applications.

Lambda vehicles are produced in the new [[Lansing Delta Township Assembly]] plant near [[Lansing, Michigan]]. The Traverse began production in September 2008 at a retooled Spring Hill Assembly Plant in Tennessee, but production was later moved to Lansing.  GM discontinued the [[Saturn Outlook|Outlook]] after the 2010 model year along with the entire [[Saturn Corporation|Saturn]] brand.

Meanwhile, GM announced a facelift of its [[GMC Acadia]] for the 2013 model year, taking the bodyshell of the discontinued [[Saturn Outlook]], while at the same time, GM would refresh its [[Buick Enclave]] and [[Chevrolet Traverse]] vehicles.

==Minivans==
GM was considering replacing the [[GM U platform|U-body]] minivans with new minivans using the Lambda platform for the 2009 model year, but due to the decline of minivan sales the plan was cancelled.<ref>{{cite web |first=David |last=Kiley |url=http://www.businessweek.com/autos/content/nov2006/bw20061127_318316_page_2.htm |title=What Do Moms Want?
