Join Autoblog editors for a full video tour of the 2019 Detroit Auto Show

The 2019 North American International Auto Show might have been a little more quiet than past years, but there were still some pretty major reveals, including the Toyota Supra, new Ford Explorer, Shelby GT500, Subaru WRX STI S209 and Kia Telluride. We also saw some lovely concepts like the Nissan IMs and Lexus LC Convertible. Senior Editor Alex Kierstein, Consumer Editor Jeremy Korzeniewski and Senior Green Editor John Beltz Snyder join me, Associate Editor Reese Counts — with Social Media Manager Michael Dylan Ferrara behind the camera — on a long walk through the show. We discuss cars, poke around the stands, dress a bloody wound and answer your questions in the Facebook comments. For more Detroit coverage, you can check out Autoblog's picks for the best in show, listen to our podcast or look at the best images from all the reveals. Finally, don't forget to watch Editor-in-Chief Greg Migliore hand over our 2019 Technology of the Year award.

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 previews 2016 Malibu ahead of New York debut

With everything going on in Geneva this week, it would be all-too easy to forget that there's still stuff going on back home in America. And the upcoming new Chevy Malibu is a prime example. Chevrolet has announced that it is bringing an all-new Malibu to the New York Auto Show next month, teasing us with this preview image and a few enticing details. For starters, when we say it's all new, this time we mean it's all new. The next-generation Malibu has been built on a new platform that uses more high-strength steel to cut 300 pounds off the curb weight compared to the outgoing model. It's also got a wheelbase that's almost four inches longer, with shorter overhangs front and rear and a roofline that tapers stylishly and more gradually towards the tail. We'll have to wait a little longer – but not too much longer – to find out more, but in the meantime you can read what Chevy's telling us so far in the press release below. Born Again: Next-Gen Chevrolet Malibu Announced Larger, lighter and more efficient Malibu to be unveiled at New York Auto Show 2015-03-04 DETROIT – Designed to deliver more efficiency, connectivity and advanced safety features than ever, the next-generation 2016 Chevrolet Malibu will make its public debut at the New York International Auto Show this April. Using a blank slate approach, Chevrolet designers benefited from an entirely new architecture, which for Malibu includes a wheelbase nearly four inches longer than the outgoing model. That, in turn, provides increased rear legroom and interior space. Due to a higher-strength steel structure, the new Malibu is also expected to be 300 pounds lighter than the current model, which benefits the sedan's fuel economy and handling. "Malibu's gorgeous styling is the result of a masterful understanding of proportions," said Ed Welburn, General Motors' vice president of Global Design. "The roofline has been stretched rearward giving a more sleek profile, while the front wheels have moved forward and front and rear overhangs have been reduced. Along with the sculpted body side, these cues help Malibu appear more dynamic and sophisticated." More details about the 2016 Chevrolet Malibu will be shared each week leading up to the vehicle's global debut. The 2016 Malibu is expected to go on sale by the end of 2015. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 115 countries and selling around 4.8 million cars and trucks a year.
