The Chevy Volt came out in an ad for Detroit Gay Pride 2012.

An estimated 5,000 revelers turned out over the weekend to celebrate Motor City Pride in downtown Detroit.

The two-day festival ended Sunday with a parade and a festival held at Hart Plaza.

General Motors' ad has a silver Chevy Volt proclaiming, “Mom, Dad, I'm electric” along with the text: “Volt runs on an electric battery and a gas generator. So, whatever revs your engine, we support you 100%. Happy Motor City Pride from the entire Chevrolet family.”

Other car manufacturers, most notably Ford Motor Company, have faced criticism for including LGBT-positive messages in their advertising. In 2008, the Christian conservative group American Family Association ended a two-year boycott against Ford after it stopped advertising to the demographic. The automaker, however, stated that it stopped running all niche advertising when the economy soured.

Last year, General Motors employees released a video in support of the It Gets Better Project, which encourages troubled LGBT teens to not cave in to bullies, because life eventually gets better.
