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.

Hurst Edition Trans Am proves the Screaming Chicken will rise from the ashes

It seems the Pontiac Trans Am steadfastly refuses to die. Ever since Chevrolet was granted a retrofied Camaro to compete with the Ford Mustang, Pontiac lovers have lamented the loss of this 1970s icon. And, looking at the Hurst Edition from Trans Am Depot, shown here at the 2012 SEMA Show, may explain what all the fuss is about.
It's not going to appeal to everyone's muscle-car tastes, but there's certainly room for a brash-and-bold black-and-gold Special Edition in many a Trans Am lover's garage. After all, if you want the keys to a custom pony car, you'll certainly get noticed in this one. If this scheme isn't your bag,, you can alternatively order your Hurst Edition in white and gold or silver and black. Oh, and don't forget a color-coordinated Screaming Chicken on the hood.
No matter which way you choose to go, your inner Burt Reynolds will appreciate the Eibach suspension kit, forged wheels with Pirelli PZero tires, functional shaker hood, fender air extractors, rear spoiler and, of course, a Hurst shifter inside. The interior is emblazoned with all manner of special touches, including a Hurst dash plate and T/A stitching on the Katzkin two-tone leather seats.

Vert-A-Pac train cars kept your Chevy Vega's price in check

Our apologies to those who've seen this before, but for the rest of the class, how awesome are these pictures of the Vert-A-Pac shipping system General Motors came up with to ship the Chevrolet Vega back in the 1970s? Developed along with Southern Pacific Railroad, GM was able to double the amount of Vega models it could ship by packing them into the unique storage cars vertically.
At the time, rail cars could fit 15 vehicles each, but Chevrolet was able to lower shipping costs by making it possible to ship 30 Vegas per rail car, in turn allowing the price of the Vega to remain as low as possible. Each rail car had 30 doors that would fold down so that a Vega could be strapped on, and then a forklift would come along and lift the door into place. All the cars were positioned nose down, and since they were shipped with all of their required fluids, certain aspects had to be designed specifically for this type of shipping, including an oil baffle in the engine, a special battery and even a repositioned windshield washer reservoir.
