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.

Burt Reynolds' movie re-creations fetch $379,500 in Vegas

The recent death of Hollywood legend and automotive enthusiast Burt Reynolds helped drive up the value of four of his former cars from the 1970s and '80s, which sold last weekend at Barrett-Jackson's Las Vegas auction for a combined $379,500. Reynolds, who died Sept. 6 at age 82, had offered three Pontiac Trans Ams — two of them re-creations of the cars he drove in "Smokey and the Bandit" and "Hooper" and the third from 1984 used to promote his United States Football League team, the Tampa Bay Bandits. The fourth was a 1978 Chevrolet R30 pickup truck, styled like the one featured in "Cannonball Run." The "Bandit" re-creation, a 1978 Pontiac Firebird Trans Am that Reynolds ordered to be as "movie-correct" as possible but featuring a custom-built 200-4R automatic transmission, sold for $192,500. The car features a freshly built Pontiac 400 cubic-inch V8 mated to a four-speed automatic and featuring all-new Butler Performance parts and air-conditioning components. Reynolds reportedly said this was his favorite car from his films, and it even came with an authentic movie-correct CB radio and CB antenna. The red retro-rocket "Hooper" '78 Firebird, with a 403 cubic-inch V8 and a three-speed automatic, hammered for $88,000. By comparison, a gold 1978 Trans Am also offered at the Las Vegas auction but not connected to Reynolds fetched $27,500. The 1987 Chevy R30 pickup was a re-creation of the Indy Hauler pace truck seen jumping over a moving freight train in "Cannonball Run." It hammered for $49,500. The fourth car never appeared in any of Reynolds' films but is instead the only surviving example of two Trans Ams used to promote the Tampa Bay Bandits of the now-defunct USFL, having been driven out onto the field by Reynolds and his late friend and co-star, Jerry Reed, during opening day one season. It also sold for $49,500. At the Barrett-Jackson Scottsdale Auction in 2016, Reynolds accompanied a 1977 Trans Am used to promote "Bandit" onto the auction block. That car sold for $550,000.

The Tesla Model S was the best-selling EV of 2015

According to numbers crunched over at Hybrid Cars, the Tesla Model S was the best selling pure electric vehicle last year with 50,366 deliveries. These numbers might not tell the whole story, since Tesla reports deliveries made in 2015 that might have been sold in a different calendar year, while other makers are tallying sales. However, it's inarguable that the Model S ended up in more worldwide driveways than the second-place Nissan Leaf, which did about 43,000 sales. In the US alone, Leaf sales were down 42.8 percent year-on-year, from 30,200 in 2014 to 17,269 last year, and that decline also increased throughout the year. That marks a great finish to a great start to 2015, when Tesla took the lead in EV sales in the US for the first quarter. On top of that, as of last year the Model S becomes the second-best selling EV ever, with 107,148 deliveries since the middle of 2012. It trails the Nissan Leaf, with well over 200,000 worldwide sales. The Chevrolet Volt/Opel Ampera combo takes a close third, with about 106,000 sales. The Nissan and Chevy rivals both launched at the end of 2010, a 16-month head start on the Tesla. Down the charts, the Mitsubishi Outlander PHEV which continues to be forbidden fruit for our market notched 39,000 sales. The BYD Qin PHEV sold 31,898 examples in China, and BYD would take the overall victory from Tesla with 58,728 deliveries if you counted all of its EV and PHEV production, such as its electric buses. The BMW i3 nabbed fourth place with 24,057 global sales. In 2011 the Munich automaker said it wanted to sell 30,000 i3s annually by 2014, but by the time the car launched the company considered 15,000 annual sales 'great for now,' so the 2015 number seems a fine place to wind up.
