Wards has named the General Motors 6.2-liter V8 engine with Dynamic Fuel Management (DFM) to its 2019 Wards 10 Best Engines Award list.
“General Motors’ thundering 420-horsepower V-8 in the Silverado exemplifies how engineers continue to find ways to improve efficiency without giving up something in return. DFM determines 80 times per second exactly how many cylinders require fuel to meet power demands. And, incredibly, it uses as few as two cylinders to propel the full-size pickup down the highway,” says Wards' Senior Content Director Drew Winter. “The truly amazing part is the cylinder deactivation is imperceptible, so seamless that the only thing the driver notices is fewer stops at the pump."
Coincidental to the award, GM-Trucks.com has just taken delivery of a long-term tester with this very engine.
“Chevrolet first introduced its Active Fuel Management cylinder deactivation system in 2005, and Dynamic Fuel Management is a natural progression of the technology,” said Jordan Lee, Small Block chief engineer. “Dynamic Fuel Management enables only the cylinders needed to deliver the power you want, seamlessly delivering the best balance of power and fuel economy.”

3.0L (B58) DOHC Turbocharged I-6 (BMW X5)

I have a 2018 GMC Sierra 1500 Denali. I just installed the 2” Rough Country front leveling kit. I couldn’t do the 2.5” because my truck has the stamped control arms. The rear of my truck still has about a 1.5” lift/rake compared to the front that I am sure is caused by the rear lift blocks since it is 4WD. Can I remove the rear blocks safely? Or will it cause any damage to my Magneride suspension? What are my options to lower the rear to match the front of my truck now?
I have a GMC Sierra 1500 it’s a 2013 and I need to do some body work. Basically I’m looking for information on replacing Both front quarter panel and if. Also any information about getting panels for the truck all the way around if you can get a set of new panels for the Truck bedside and for a quarter. Any information would really help thank you
just replaced the windshield on my 15 Yukon and the guy told me that I might need to recalibrate my adas systems ad rain sensors.
Did anybody here had to go through this process? I’ve actually called the dealer which told me that 99% of the times there is no need to recalibrate the system...
