More Practical Power: GM Duramax


The Duramax is a line of Diesel engines available in light duty and medium duty trucks. Though this motor is sold exclusively by the American automotive giant General Motors, it was actually designed by Isuzu. The 6.6-liter Duramax is sold by a GM-Isuzu venture known simply as DMAX. Moraine, Ohio is the sight for the DMAX plant and GM has sold nearly 2,000,000 DMAX engines to date.

The Latest DMAX Beast: LML

When it comes to towing and hauling, the GMC and Chevy brands depend on the latest DMAX from Ohio. The 6.6 liter LML is the latest rendition of the GMC Duramax, V8 diesel engine. This improvement over the LMM DMAX engine emits less pollutants while still delivering 397 horses and 765 lb-ft of torque. Fuel efficiency and power are finally combined into one package though total MPGs will vary from vehicle to vehicle. DMAX has also agreed to invest $60 million into an Ohio plant which manufactures these engines. Apparently, both Isuzu and GM want to see the DMAX engines become even more fuel efficient. The 500 individuals employed at the plant are certainly thrilled as are people who drive the GMC Sierra and Chevy Silverado which feature the LML diesel engine.
