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.

All of the Bond cars of 'No Time To Die' (caution for spoilers)

Note: The following overview of the cars in No Time To Die contains spoilers. Read at your own risk, or come back after seeing the film to make sure you caught everything.   No Time To Die picks up right around where Spectre leaves us. James Bond (Daniel Craig) and Madeleine Swann (Lea Seydoux) are driving along in Bond’s restored and iconic DB5 in Matera, Italy. Things donÂ’t stay all that cheery for long in picturesque Matera, though. As is tradition in Bond films, the first car chase hits us with an explosion of action in what's a super-long opening scene. Fourth-gen Maserati Quattroporte: The baddies in the beginning are driving a Maserati and chasing after Bond in the DB5. Specifically, theyÂ’re in a fourth-gen Quattroporte, which feels right for a chase scene in Italy. Its squared-off looks are mean enough, and its Italian growl is a good background soundtrack to the DB5Â’s inline-six. In addition to the Quattroporte, the chase scene in Matera is home to a couple of the best stunts of the entire movie, including the arch jump done with a Triumph motorcycle seen in trailers — Matera is extremely hilly. Eventually, Bond and Swann find themselves in the DB5 again together, which is where the famous gatling gun scene from the trailer commences, but not before the bulletproof windows and body of the DB5 are thoroughly tested. RIP to the first-gen Range Rover Classics and Jaguar XFs that joined the Maserati in pursuit of Bond (here's a list of other Bond cars over the years). As the DB5 escape scene concludes, we catch a glimpse of what appears to be a Ferrari from the 1970s. However, the view was far enough away that weÂ’ll need a second look to be sure of the exact model. Land Rover Series III: Next time we see Bond, heÂ’s fishing in Jamaica and driving around a blue Land Rover Series III. ItÂ’s yet another of the many Land Rover products featured throughout the film, and unlike most of BondÂ’s Aston Martins, this one doesnÂ’t seem to have any unique features. The other intriguing vehicle out of Jamaica? An old Chevrolet Bel-Air expertly and effectively piloted by Bond newcomer, Ana de Armas. Next up, we get a few shots of the new and still-not-for-sale Aston Martin Valhalla mid-engine supercar (also seen in trailers). BondÂ’s old boss M is in the scene which appears to have been shot in some secret wind tunnel of sorts. Much to our dismay, nobody ends up driving the Valhalla in the film. Could it be a teaser for what the next 007Â’s car is?

Recharge Wrap-up: BYD electric buses at Special Olympics, hybrids perform better than rated

A new study finds that real-world fuel economy of hybrids could be significantly higher than EPA ratings. Researchers at the University of Vermont, with the help of their own "total on-board tailpipe emissions measurement system," found the fuel savings of Toyota Camry Hybrid over a standard Camry to exceed its sticker values by 18 percent on the highway and 33 percent in the city. The results of this study suggest that the projections of the fuel and emissions benefits of hybrids could be adjusted to reflect more these more positive real world values. The study's authors, Britt A. Holmen and Karen M. Sentoff, say more research is warranted based on these findings, and that "similar studies can be used to develop robust models of all types of HEV platforms under actual driving conditions and improve quantitative estimates of the future fleet contributions to the US CO2 emissions inventory and petroleum consumption."

Chevy displayed the silver Volt alongside a Camaro and Malibu of the same color and model year. The Volt also recently made an appearance at the premier of Tomorrowland with George Clooney behind the wheel. Read more at The News Wheel. BYD electric buses provided transportation at the Special Olympics 2015 World Games in Long Beach, CA. Shuttling 6,500 athletes required the help of multiple charter companies, including local buses from the Chinese automaker. "BYD stepped up majorly as one of our key supporters and their tremendous efforts made our athletes feel welcomed," says Long Beach Community Foundation President and CEO, and 2015 Host Town Transportation Coordinator Marcelle Epley. "We depended on them, and they came through 100 percent." Both Los Angeles and Long Beach have recently decided to purchase electric buses from BYD. Read more in the press release below. BYD Zero-Emission Buses Used to Transport Athletes at 2015 World Games LONG BEACH, Calif., Aug. 2, 2015 /PRNewswire/ -- This week the largest Special Olympics ever was hosted in the City of Long Beach – thousands of athletes, coaches, dignitaries and families descended upon Los Angeles for what was a spectacular week of uplifting camaraderie, sportsmanship and competition.
