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.

eBay Find of the Day: 1990 Chevy 1500 454 SS with just 7 miles

When trawling the classifieds either on a buying mission or merely a time-wasting mission, we spend a lot of time poring over photographs comparing the seller's idea of "Like New!" with our idea of it. It's hard to argue with seven original miles on the odometer, though, which is what this 1990 Chevrolet 1500 454 SS has. It's being sold by Country Chevrolet on eBay, the same dealer who sold the truck to its one and only owner 25 years ago. The purchaser bought two of them and left this one in a garage under a car cover, said garage being less than seven miles away from the showroom floor. Better yet, you can buy with confidence because the seller "has collected all records," which we expect would be the slimmest manilla folder in the history of receipt-keeping. For those unfamiliar, the 454 SS was a half-ton, regular cab, 2WD pickup powered by a 454 cubic inch (7.4-liter) V8 with 230 horsepower and 385 pound-feet of torque shifting through a three-speed transmission. This was at the same time the Chevrolet Corvette used a 5.7-liter V8 producing 250 hp and 350 lb-ft. The pickup rode on exclusive wheels and only came in black with red cloth inside. The only extra-cost option on this example is an $18 locking fuel filler cap, which, according to the 454ss forum, means it should have cost about $18,460 out the door, the equivalent of about $34,000 today. At the time of writing there are zero bids, but proceedings open at $45,000 and Country Chevrolet wants $49,000 if you have to have your time capsule right now.

Woodward Dream Cruise Photo Gallery | Classics and American muscle

The 2022 running of the Woodward Dream Cruise just went down, and we were there from morning to evening drinking in the sweet sights and pre-emissions exhaust fumes. Yes, it’s a little smelly on Woodward Ave. this time of year. Just like always, the Dream Cruise invites all comers to cruise their machines on Woodward from Ferndale, MI to Pontiac, MI. Everybody is invited, but the original intent of the Dream Cruise was to highlight classic American muscle cars. YouÂ’ll see plenty of those in our mega gallery above, but weÂ’ve sprinkled it with a bunch of other vehicle types, such as modern muscle and other intriguing American vehicles. Similar to years past, though, sometimes the classics arenÂ’t the most entertaining thing to look at on Woodward. ThatÂ’s why weÂ’ll have other mega galleries coming soon, highlighting the weird cars and (great) dogs of the Cruise, all the imports and exotics you can imagine and a special one for all the trucks of Woodward — perhaps even more so than in years past, the truck population on Dream Cruise day was quite high. Click through above to see all the classics you wouldÂ’ve seen had you been roadside on the day of the cruise. And if you missed this yearÂ’s event, make sure you check out what happens next year. You wonÂ’t be alone, as itÂ’s estimated that over 1 million people attend the Dream Cruise to either watch from the side of the road or to sit in the most glorious traffic jam in the world.
