Introduced in the 2005 model year, the Pontiac G6 Sedan took over for the Grand Am and Grand Prix in the maker's lineup. The Pontiac G6 was originally unveiled at the 2003 Detroit Auto Show. The G6 was put in place to reinforce GM's idea that their daughter division was the sportier of the bunch. The Pontiac G6 was and still is available as a sedan, convertible, or coupe. In 2005 the G6 was ranked at number eleven in the top selling cars in America.

The G6 Sedan comes standard with a 2.4L Ecotec LE5 4-cylinder engine, producing up to 169 horsepower. In the 2005 model year, Pontiac released a G6 convertible. The retractable hardtop put the G6 convertible in the running with much more expensive car brands, such as the Infiniti G35. The GT trim of the G6 came with TAPshift, much similar to the AutoStick. The TAPshift gave the G6 the ease of driving an automatic, but allowed the driver to upshift or downshift manually when necessary. The 2006 model year also introduced 201 horsepower, a much needed boost for a car marketed as "sporty." It was not until 2007 when Pontiac gave the G6 GT an engine upgrade to a 3.9L V6 that produced 252 horsepower. The latest G6 trim is the GXP. The GXP had a revamped front end and featured two air scoops on the hood.

When the G6 Sedan was first released, America got to get their first glimpse through Oprah Winfrey. She famously gave an entire studio audience, 276 people, each a Pontiac G6 of their own. By releasing the car nationwide by donating 276 cars to people on an incredibly popular talk show, Pontiac succeeded in making the G6 a household name overnight. However, soon after the show debuted controversy began. Though the sedans were given to people in need in Oprah's audience, the taxes were not paid. Many of the winners were unable to even keep the vehicle because they simply did not have enough money to cover the cost of taxes.

The Pontiac G6 Sedan is also used in racing. The G6 took the place of the GTO.R in the Rolex Sports Car Series. Also, the G6 GXP is involved in Powerade Drag Racing. Though the G6's marketing campaign was incredibly different than that of its competition, the maker succeeded in creating a brand that all became familiar with very quickly. Since then, other makers have been pushing vehicles more and more on talk shows by giving them away to deserving audience members. However, none have done it on quite the grand scale that Pontiac did.
