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.

Junkyard Gem: 1980 Chevrolet LUV Mikado

During the 1970s and into the 1980s, each member of the Detroit Big Three imported Japanese small pickups and sold them with Ford (Mazda Proceed), Dodge/Plymouth (Mitsubishi Forte), or Chevrolet (Isuzu Faster) badges here. Ford developed the Ranger and killed the Courier for 1983 (though Americans could still buy the Mazda-badged version all the way through 1993), while The General axed the LUV after the S-10 debuted in the 1982 model year. Isuzu sold the same truck as the P'up through 1987, though, and we might as well follow up our recent P'up Junkyard Gem with its LUV predecessor. LUV stood for Light Utility Vehicle, and I've managed to spot a handful in the boneyards over the years. This one now resides in a yard in northeastern Colorado. The Mikado trim package included striped seat upholstery and a sporty steering wheel, plus these cool dash badges. As far as I can tell, no LUV Mikado advertising featured any Gilbert and Sullivan tunes. This one is fairly rusty for Front Range Colorado, and it has endured a bed swap from some other small truck. The engine is the 75-horse Isuzu 1.8-liter. Members of this engine family went into everything from Chevy Chevettes to Isuzu Troopers in the United States. Very unusually for a small pickup during the Malaise Era, this one has a luxurious automatic transmission. Acceleration must have been a leisurely affair in this truck. Air conditioning? Unheard of! Someone stuck every one of their lunchtime apple stickers on the driver's door. After 41 years of work, this truck is done. Come on strong in a LUV of your own!

Chevy Spark EV will go on sale in Maryland

The single-charge range of a Chevrolet Spark electric vehicle may not blow away anyone who's used to driving on a topped off tank of gas. But a full charge will actually get a Spark EV about halfway across the state of Maryland. Which is good because that state will be the first on the East Coast to sell the battery-electric model. General Motors said this week that Chevy Spark EV sales will start in Maryland this spring, and that federal and Maryland tax credits will get the out-of-pocket price of the Spark EV below the $18,000 threshold. GM took the opportunity to tout the Spark EV's 119 miles per gallon equivalent rating and says Maryland has sufficient charging infrastructure for drivers to welcome the EV without too much trouble. Last June, Spark EV distribution was reported to be ready to extend beyond the Pacific Coast. Specifically, Ohio was thought to be next in line to get Spark electric vehicles after four state car dealerships listed the model on their websites. GM's Randy Fox, however, quashed that real quick, saying only California and Oregon had sufficient infrastructure to support the Spark EV. GM first announced the Spark EV for public (or at least American) consumption back in 2011. Last year, the General sold 1,145 Spark EVs, up 87 percent from 2013. For more on the Maryland expansion, take a look at GM's press release below. Chevrolet Spark EV Plugs into Maryland Customer demand drives addition of East Coast; features locally sourced drive unit 2015-01-22 WASHINGTON, D.C. – Chevrolet will start selling the Spark EV in Maryland this spring, expanding the pure electric mini-car's "range" to the East Coast. The Spark EV is the most efficient U.S. retail electric vehicle on the market, delivering an EPA-estimated combined city/highway 119 MPGe fuel economy equivalent and 82 miles of EPA-estimated combined city/highway range. It is priced as low as $17,845, after federal and Maryland tax credits – and it features a locally sourced electric motor and drive unit, manufactured at General Motors' Baltimore Operations facility in White Marsh, Md. "The Spark EV has been one of the most well-received electric vehicles in the industry and customer demand helped make the decision to expand its availability to Maryland," said Steve Majoros, Chevrolet director of car marketing.
