The Northstar engine series of automobile engines was General Motors' most technically complex 90 V engine architecture. The family is most associated with Cadillac's Northstar V8, but the family has also seen use at Oldsmobile (as the Aurora L47 V8 and "Shortstar" LX5). The Oldsmobile variants went out of production in 2003, but the Northstar family did expand with longitudinal and 4.4 L supercharged versions. The Northstar name was used outside Cadillac as well, with Pontiac and Buick versions carrying that moniker.
GM ceased production of the Northstar engine in July 2010. Production of the final cars to include the engine, the Cadillac DTS, Buick Lucerne, and Cadillac STS, ended in 2011.[1] Newer Cadillac V8 models like the CTS-V use the GM small-block OHV engine, marking a return to a simpler push rod engine design.[WIKI]
