A New Report Corroborates What We Were Told Last Year

Currently, the highest max tow rating for a General Motors half-ton Duramax truck is 9,300 lbs. That appears to be changing. According to GM-Trucks, the 2021 Chevrolet Silverado 1500 and 2021 GMC Sierra 1500 pickup trucks are set to see tow rating improvements for both the previously mentioned 3.0L Duramax LM2 engine as well as the 2.7L turbocharged four cylinder, codenamed L3B. While neither Chevrolet nor GMC have announced anything publicly, the report essentially proves what we were told by engineers roughly a year ago.

Another update expected is the integration of the GMC MultiPro tailgate onto the Chevrolet Silverado 1500, said to be called Multi-Flex.

As it stands, 95 percent of Chevrolet and GMC light duty truck customers don’t tow over 9,000 pounds, which spurred a conscious decision to prioritize fuel economy in the LM2 Duramax Chevrolet Silverado and GMC Sierra trucks. But in a market where the name of the game is to constantly one-up the other, whether it’s towing, payload, horsepower, torque, or 0-60 times… settling for 95 percent just won’t do.

Currently, the Ford F-150 Power Stroke is rated to tow 11,400 pounds, while the 2020 Ram 1500 EcoDiesel is rated at 12,560 pounds.

Despite being down on towing, the Chevrolet Silverado 1500 Duramax 4X2 achieving an incredible 33 mpg highway and 23 mpg city. The Sierra 1500 Duramax comes in at 30 mpg highway and 23 city. The difference in highway fuel economy reflects a corporate fleet average of how customers option and spec their vehicles – where the GMC tends to have more content, and thus more weight in the test. EPA fuel economy for the 2021 Chevrolet Silverado 1500 and 2021 GMC Sierra 1500 in any engine or trim level awaits publishing.

Compared to the V6 diesel engines that Ford and Ram offer, the Silverado 1500 and Sierra 1500 Duramax trucks integrate an inline six diesel. By nature, this configuration is a smoother, more balanced engine that returns superior NVH without adding balance shafts. They don’t have as much rotating mass that we have to support that a V6 does, and therefore negates the need for balance shafts, while there are also advantages to its packaging.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
