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.

Chevy teases next-gen Volt at fan event in LA

Barely two months before its planned debut at the 2015 North American International Auto Show, Chevrolet has released yet another batch of teaser images of its second-generation Volt. Unlike the first image, though, which just showed the car's rear badge, there's a lot more to this quartet of shots. The first three images show off the nose of the next-gen model and come from a fan event in Los Angeles. What we can see is a sleeker front end, with an evolution of the silver grille inserts previously seen on the original Volt and Spark EV. Gone is the current car's split upper grille, in favor of a more conventional arrangement. The sharper, more angular headlights are also an evolution of the lamps seen on the current Volt. Chevrolet also took the opportunity to announce a new location-based charging system that uses GPS to adjust the vehicle's charge settings, including the charge level, while also announcing that the next-gen car will feature more intuitive charge indicators that will be better able to inform owners of their car's charging level. The tech will mean that the Volt 'knows' when it is parked at home, and can thus automatically optimize charging for off-peak times, and so on. Take a look at the teaser images at the top of the page, and then head below for Chevy's press release announcing the new features. Next-Gen Chevy Volt Offers More User-Friendly Charging 2014-11-20 GPS makes charging more convenient Portable charger is easier to access Intuitive visual cues show charge status DETROIT – If there's one thing Chevrolet Volt owners love about their cars, it's being able to recharge the battery easily. Evidence of that is a U.S. Department of Energy study that shows more than 80 percent of all trips by Volt owners did not use the range extender. Chevrolet has made the charging system in the next-generation Volt even easier for customers to recharge the battery – and to check the charge status. The next-generation Volt debuts in January at the North American International Auto Show. "Chevrolet used the real-world experiences of today's Volt owners to make the charging process simpler and more convenient in the next-generation Volt," said Andrew Farah, chief engineer for the Volt.

Kurt Busch to shake and bake (again) in Ricky Bobby car at Talladega

Kurt Busch will channel Ricky Bobby for another NASCAR race, this time driving a Wonder-sponsored Chevrolet SS, in this weekend's Camping World RV Sales 500 at the Talladega Motor Speedway. Unlike past tie-ins, though, there's actually an element of sponsorship here (the "Me" car was done when Busch was running on a team without sponsorship).
It was arranged by Flower Foods, the new owner of the Wonder brand. Wonder was part of the bankrupt Hostess company, which temporarily exited the US market 2012, and set off the Great Twinkie Shortage.
Busch has made something of a habit of channeling characters from famous racing movies, most recently running Tom Cruise's City Chevrolet livery from Days of Thunder in a Nationwide Series race earlier this year. Busch kicked off his movie-inspired antics, though, at Talladega in 2012, when he raced El Diablo's ("It's like... Spanish for like a fighting chicken") "Me" car complete with a cougar on the hood. He even went so far as to channel the lovable idiot that is Ricky Bobby during the race, dropping a few catchphrases about macchiatos and slingshots.
