GTP trim level. The GTP's new 3.8 L supercharged V6 now made , up 20 from the previous generation. TAPshift was also introduced as well as a Competition Group package (Comp G). 2005–2010 With the discontinuation of Oldsmobile in 2004, Pontiac went through a complete product revamping through this period. The Grand Am was replaced with the mid-size G6 in 2005. The Grand Am was produced for the 2005 model year to fill the gap until the new G6 coupe and convertible became available for that model year. The Bonneville ended production in 2005 after nearly 50 years of production. Although it was not directly replaced, the RWD G8 introduced for the 2008 model year did fill some of the market voids. The Solstice concept shown in 2002 was approved for production as a roadster (2006-2009) and, for a few months, a total of 1,266 coupes (2009) were built in Wilmington, DE before the end of Pontiac. In contrast, over 64,000 Solstice Convertibles were manufactured on that same line. The controversial and slow-selling Aztek was finally phased out and replaced by the Torrent, which was identical to the Chevrolet Equinox. In 2005 the Sunfire was discontinued and replaced by the new Pontiac Pursuit (later named G5 for the American market). Initially, Pontiac did not plan on offering the G5 in the United States, however, dealer pressure to fill the gap left by the discontinuation of the Sunfire caused Pontiac to introduce only the coupe variation into the U.S. The 4-door sedan version was available in Canada as the Pursuit throughout the model run. The high-performance GXP trim was introduced in the Grand Prix line in 2005, adding GM's LS4 V8 engine that produced 303 horsepower and 323 lb. ft. of torque. This engine was built to give buyers a V8 sedan option until the all-new G8 arrived in 2008. In 2008, the Grand Prix ended production, and the launch of the Australian-built RWD G8 commenced. The G8 gained positive reception for its high performance and low costs. Many noted the G8 as the poor man's BMW M5, due to its similar performance at a much cheaper price. The G8 GXP was the most powerful production car Pontiac had ever built and is regarded as the best driver's car ever to wear the Pontiac badge. The Holden Ute was scheduled to be launched as the G8 ST before it was canceled
