All of these engines are 12-valve cam-in block or overhead valve (OHV) engines, except for the LQ1; which uses 24-valves driven by dual overhead cams or (DOHC) instead. These engines vary in displacement between 2.5 and 3.4 liters and have a cast iron block and either cast iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S; but continued being produced in China until 2010. This engine family was the basis for the GM High Value engine family. Some refer to these engines as X engines due to first usage in the X-body cars. ==Generation I== The first generation of modern small GM 60° V6 engines featured an iron block and heads with inline valves. This "clean sheet" design was introduced in 1980 and versions were produced through 1995. Two different blocks with minor differences were developed: * A transverse engine family for front-wheel drive * A longitudinal engine family for rear-wheel drive 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「General Motors 60° V6 engine」の詳細全文を読む スポンサード リンク
