General Motors 60° V6 engine

The General Motors 60 degree V6 is a family of small V6 engines made for both longitudinal and transverse installation, first used in the X-body cars and for that reason sometimes called the X engines. The engines displace between 2.8 and 3.4 litres, have cast-iron blocks with iron or aluminium heads, and use twelve-valve cam-in-block layouts, apart from the LQ1, which has dual overhead camshafts and twenty-four valves. Chevrolet developed the family, although every General Motors division except Saturn and Geo used it. Production began in 1980 and ended in 2005 in the United States, with output continuing in China until 2010. The family was the basis of the GM High Value engine family, and the article separates it from the unrelated GMC V6 designed for commercial vehicles. Early versions such as the LE2, LH7 and L44 powered A-body and X-body cars, the Pontiac Fiero and other models.
