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.

Forza Horizon announces January Recaro Car Pack with LFA N"urburgring Edition

Another month, another car pack for Forza Horizon. This time it's the Recaro Car Pack featuring a motley gang of cars and trucks: the 1983 GMC Vandura G-1500, 1995 Ford Mustang Cobra R, 2012 Cadillac Escalade ESV, 2005 Mercedes-Benz SLR, 2012 Lexus LFA Nürburgring Edition and 2012 Lotus Exige S.
It'll be up for download on Xbox Live on Tuesday, Jan. 1, 2013 for 400 MS Points. As usual, if you have the Forza Horizon Season Pass you can get them all free, and Season Pass holders will also get a bonus car that's not pictured: the 2009 Pagani Zonda Cinque Roadster.
The Pagani is everything opposite to that Vandura, but while you might not ever win anything with the van, you can always use the back of it as a place to give out free hugs. Check out the video and press release below for more details.

GMC goes to the dark side with Terrain and Acadia Black Edition

GMC recognizes how many of its SUVs are customized immediately after purchase. It's not uncommon for a big SUV to be ordered in black, and then to receive a murdered-out look on top of that: black wheels, black tint, black trim. According to GMC, roughly 1 in 5 new SUV buyers gets their new vehicle customized, and to better serve those customers, GMC is now saving them the trouble of doing it aftermarket. As per GMC's statement: "Black Editions answer the specific desire for a blacked-out effect and come direct from the factory ingrained with distinct personality." Both the 2019 GMC Terrain and Acadia will be available in the special "Black Edition" from this summer on. They both feature blacked-out grilles, roof rails, mirror caps and trim. The Terrain's Black Edition, available on SLE and SLT spec, gets 19-inch gloss black aluminum wheels, and the SLT-only Acadia Black Edition gets 20-inch machined aluminum wheels with black accents. Despite the name, the Black Editions are both available in four colors other than just black — even if those are mainly shades of grey with an option for white as well. Related Video:
