Northstar Engine Series
The Northstar engine series of automobile engines is 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 are no longer in production, 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. Newer Cadillac V8 models like the CTS-V use the Chevrolet LS OHV engine, marking a return to simpler, more robust engine design.
