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.

Let's Drive NYC is GM's car sharing program for the Big Apple

Under a new car sharing program offered by General Motors and others, a New York Minute will cost about 15 cents. GM is working with a luxury-apartment building owner and a parking lot operator to run a car sharing program in Midtown Manhattan. The program is called Let's Drive NYC and it was announced Thursday. Let's Drive NYC is being offered to residents of the Ritz Plaza, a 479-unit luxury apartment building near New York's Times Square. The program is being run with the help of Icon Parking Systems, which runs about 200 parking garages in Manhattan where the cars can be parked. GM is contributing eight Chevrolet Trax crossovers and two Chevrolet Equinox SUVs, and the automaker is slated to add more vehicles "later." Residents of the Ritz Plaza, which is owned by Stonehenge Partners, can make "periodic apartment lease payments" and in exchange receive electronic credits for three hours of driving a month. After those three hours are up, the drivers will be charged less than $10 an hour, or as much as $75 a day. The program was piloted earlier this year to some of the apartment's tenants. The program marks the second bit of car sharing news in New York within the past two months. In August, Mercedes-Benz and Smart parent Daimler announced that its Car2go car sharing service would expand into Queens and add about 100 Smart ForTwo two-seaters to the city's program. Car2go made its New York debut in Brooklyn last October and has attracted more than 27,000 members since then. You can take a look at Let's Drive NYC's press release below. GM Unveils 'Let's Drive NYC' Car-Sharing Program NEW YORK, Oct. 1, 2015 /PRNewswire/ -- Running an errand to a big box store or planning a weekend excursion are about to get easier for some Manhattan residents because of a car-sharing program revealed today by General Motors.

The fleet currently includes eight Chevrolet Trax small SUVs and two Chevrolet Equinox compact SUVs, with more vehicles to be added later.

2015 Chevy Colorado takes Motor Trend Truck of the Year calipers [w/videos]

The final winner of Motor Trend's prestigious Golden Calipers has been named, with the 2015 Chevrolet Colorado taking the title of 2015 Truck of the Year, likely shocking those who thought Ford's all-aluminum, next-generation F-150 would take the crown. But win the Colorado did, beating not only the new Ford, but two other brutish Blue Ovals in the F-450 and Transit. The midsize pickup also bested its brethren from General Motors, beating the heavy-duty Chevy Silverado 3500, GMC Sierra Denali 2500 and the GMC Canyon, the Colorado's fraternal twin. After an unprecedented two-year stint with the Golden Calipers, Ram sat this year's awards out. Most impressive about the Colorado's victory isn't that it simply beat the US market's other trucks, it did so with a unanimous vote. Praise from MT's editors focused on the trucklet's price, spacious interior, fit and finish and performance. Former Autoblog staffer Jonny Lieberman called the Colorado's steering the best he'd "ever experienced on any truck, full stop," in MT's awards article. "After days of testing, hundreds of miles on the road, and our most rigorous truck testing program to date, our editors unanimously selected the Chevy Colorado as our 2015 Truck of the Year," said MT boss Edward Loh. "Colorado is a smart, capable, and refreshingly honest truck that makes a strong value and efficiency statement. It's perfectly sized and suited for the needs of many of today's truck users." The Colorado joins the 2015 Volkswagen Golf and 2015 Honda CR-V among Motor Trend 2015 award winners.
