The high performance Buick Regal GS will power up the Chinese car market in August. The GS has a 255hp and 400nm turbocharged 2.0 four-cylinder Ecotec engine. The Regal GS comes as an import first but will later be made in China by the Shanghai-GM joint venture. More and more automakers are bringing high powered cars to China, the markets want them now. A healthy development that once again shows that horse power still matters.
