what year did cadillac stop using the northstar engine
Northstar engine series GM ceased production of the 4.6 L Northstar in 2003, and the remaining series in July 2010. The final cars to receive it, the Cadillac DTS, Buick Lucerne, and Cadillac STS, rolled off the line in 2011.[1] It was replaced by the GM LS small-block OHV engine, used in newer Cadillac V8 models like the CTS-V, marking a step back to a simpler, more reliable push rod engine design.
