GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

Basic configurator for 2021 Chevy Colorado and GMC Canyon slips online

TFLnow discovered basic configurators for the 2021 Chevrolet Colorado and GMC Canyon are already online at GM's site for employee discounts. These aren't the fully-featured whiz-bang configurators that will show on the retail websites soon, but they include a bunch of the relevant info a shopper would be looking for. After trim changes detailed earlier this year, the 2021 Colorado offers the most choice, even with the two-door base model gone. Cutting the entry-level Colorado also means the entry-level price has gone up by $3,900; the 2020 Colorado could be had for $22,495, but the 2021 model starts at $26,395 after the $1,195 destination charge. That gets you the extended cab with a standard bed in two-wheel drive. The 2WD crew cab with a short bed starts at $28,295, and the 2WD crew cab with a standard bed starts at $30,595. At the top end, the ZR2 model runs $44,395, which is $200 more than the 2020 version. The color palette isn't complete, but the options page shows a number of choices for packages. The Redline Special Edition Package goes up $10 to $2,690, the Tonneau and Step Package increase $100 to $1,195, a new Chrome Package puts shiny stuff in places like the door handles and steps for $300, while the Black Bowtie Emblem Package drops $80 to $140. The one-inch front leveling kit, which was thought to cost $150 based on early order information GM Authority had seen, is here listed for $450 and available on the Colorado but not the Canyon.  The Canyon makes matters a tad simpler by having many options locked in depending on which one starts with — 2WD Elevation Standard starting at $27,595, 2WD Elevation for $31,195, 4WD AT4 with a cloth interior for $39,395 or AT4 with leather for $41,195, the least expensive Denali starting at $42,095 for a crew cab short box with 2WD. The Elevation includes items like the Convenience Package that are options on the base model, and also offers a $1,400 High Elevation Package conferring heated and power black leather seats, plus a heated steering wheel, that can't be optioned on the Elevation Standard. The pinnacle is the crew cab with a standard bed in Denali 4WD trim for $45,895. Colors and many of the final options and accessories, such as the AT4 Off-Road Performance Edition Package we've heard about, are also missing here, but there's heaps to play around with to get an idea of what you'll be in for if you're considering a 2021 Canyon.

General Motors has just announced pricing for its new midsize pickup trucks, the 2015 Chevrolet Colorado and GMC Canyon. Chevy's truck starts at $20,100, *not including $895 for destination, and the GMC starts at $20,995, **not including $925 for destination. These prices are for the base, extended cab models with the 200-horsepower, 2.5-liter inline four-cylinder engine.
Comparatively, these prices fit nicely with the $18,125 starting MSRP of the Toyota Tacoma and the $21,510 of the Nissan Frontier. Compared to the Colorado, the Canyon's extra $895 gets you niceties like LED running lamps, 16-inch alloy wheels, and a four-way power driver's seat.
Both trucks come standard with the 2.5-liter engine, and a more powerful, 305-hp 3.6-liter V6 will also be available. Pricing has not been announced for the upcoming diesel model, which is expected to launch for the 2016 model year.
