GM ends Northstar V8 production

General Motors has confirmed that it will cease production of the DOHC Northstar V8, one of the most advanced engines the company has ever built after 17 years of production, sometime near the end of July. Northstar V8 engines have been in service since 1993 when the 295 hp L37 Northstar made its debut in the Cadillac Allante.

Back in 1992, the 4.6-liter Northstar V8 was an overhead-cam, all-aluminum V8 and used in the Cadillac Allante. It was GM's first overhead-cam V8 and it introduced innovative features to the market. The Northstar V8 is currently available as either a 292-hp or 320-hp motor, or when supercharged in cars like the STS-V makes a total of 469-hp.


For a decade or so, the Northstar was a Cadillac exclusive, but years later, the engine architecture of the Northstar was used for other brands such as Oldsmobile and Buick.

There have been many different variants on the Northstar over the years, including a 3.5-liter V6 that was derived from the Northstar and used in an Oldsmobile before the brand ceased.

GM had planned the Ultra V8 or UV8 to replace the DOHC Northstar V8 engine, but this program was shut down when the company started to lose money, leading to its bankruptcy in 2009. The Northstar V8 could be replaced by a new twin-turbo V6 motor, designed to rival Ford's EcoBoost technology.
