GM Plans new light duty 4.5L V-8 diesel for North America


:

General Motors announced that they will be building an all new 4.5L V-8 turbo-diesel starting in 2009. This is the new engine that Dr. Gary Smyth alluded to in our recent interview. The new engine meets all Tier 2 Bin 5 requirements for 2010 and beyond meaning it will be fifty state legal. The new twin cam 32 valve engine is specifically designed to fit within the same packaging envelope as the current small block V-8 that is widely used in the the GM lineup.

The new engine will appear first in the Chevy Silverado/GMC Sierra and Hummer H2 starting at the end of 2009. Because the new engine can fit anywhere a small-block does it can fit in a wide array of vehicles including the upcoming rear drive Zeta platform that will be used for the next generation Impala and many other cars. The new Duramax will be rated at over 310 hp and 520 lb-ft of torque.
