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.

UAW to vote on strike at Kentucky Corvette plant

The current wait time for a new Chevrolet Corvette Stingray is well, not short. With word of a strike at the Bowling Green, KY factory responsible for seventh-generation sports car, though, that wait time could end up growing substantially.
Now, a strike is still a ways off. UAW Local 2164, which represents the 800 workers responsible for screwing the Corvette together, is set to vote on authorizing a strike today, but even if the employees give the action a go, it's far from a sure thing. According to The Tennessean, both regional and national union officials would need to put their stamp of approval on strike action.
"The membership has to vote to strike, but it's just a step in the process," said Gary Casteel, the UAW's Region 8 director and one of the people that would need to authorize a strike action. Casteel told The Tennessean, "It's purely a local situation, though. They are having some issues with the local management."

Michael Jordan's cars showcased in 'The Last Dance' documentary

After the masses begged and pleaded for an early release, ESPN finally unlocked the doors to the biggest production in company history last month. Episodes 1 and 2 of The Last Dance, a 10-part documentary special about Michael Jordan, the Chicago Bulls, and the 1997-1998 season, was released at last on April 19, 2020. Each week since, two new episodes have aired on Sunday nights, and the next two, episodes 7 and 8 are scheduled to drop this weekend on May 10. With unprecedented video access to MJ, who became averse to the media during his playing days, a byproduct from The Last Dance is a look at some of Jordan's cars. The Goat's taste ranges across a number of brands, but they all had one thing in common: performance as a top priority. Below, we have listed the rides that have already appeared in the series, and each week, we will update with new car cameos. Chevrolet Corvette C4 The photo above somewhat epitomizes one of the themes of The Last Dance. Everybody, whether that was men, women, children, franchise owners, reporters, coaches, teammates, or opponents, wanted a piece of Jordan. If that meant stopping in the middle of the road to get an autograph, then so be it. Around town, MJ was fairly easy to spot due to his flashy cars that occasionally wore Bulls red. Jordan has driven numerous Corvettes throughout the years, but the C4 is unique in that it was Chevy's top ride when Jordan signed an endorsement deal with the American company during his rookie year in 1984. Two famous photos, one in front of the Chicago skyline, show him standing next to a C4 with the license plate "Jump 23." This exact car, however, came later, as indicated by the squared-off taillights. He went on to star in a number of Chevrolet commercials with vehicles such as the Blazer and S-10 pickup truck. Chevrolet Corvette C5 The most notable Corvette His Airness ever owned was likely the C4 40th Anniversary ZR-1, but he also drove a C5 coupe at one point. Roughly nine minutes into the first episode, Jordan is seen driving the chrome-wheeled targa top into the parking lot at the Berto Center, the Bulls old practice facility.   Ferrari 550 Maranello Roughly three minutes into episode four, viewers get a glimpse of Jordan's exotic taste in the form of a red Ferrari 550 Maranello.
