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.

2016 Chevy Volt will start at $33,995*

One of the biggest mysteries regarding the 2016 Chevy Volt has been revealed. Chevy announced today that the next-gen plug-in hybrid will have an MSRP of $33,995, which includes GM's $825 destination fee. That's a few hundred dollars less than the current Volt, which has an MSRP of $34,170. The second-gen Volt is about more than a price cut, though. The car has an increased all-electric range (50 miles vs. 38 in the current model) and better fuel economy. Once the battery power runs out – which it doesn't do, in most situations, since 90 percent of all trips are electric-only – the no-longer-premium-only gas engine offers 41 miles per gallon, up from 37 mpg. We know most buyers are price-conscious, and with the still-available federal tax incentive of up to $7,500, the new Volt can be had for $26,495. That should put a spring back into sluggish Volt sales, which are down 46 percent year-over-year so far in 2015. Through the end of April, GM has sold a cumulative 76,136 first-gen Volts since introducing the car in 2010. Chevrolet Announces 2016 Volt Pricing Next Gen delivers more technology at new price as low as $26,495 DETROIT – The Chevrolet Volt is poised to continue to bring new owners to the electric plug-in family. Pricing will be as low as $26,495 after the full federal tax credit of $7,500. (Federal tax credit can range from $0 up to $7,500.) In California, the vehicle's largest market, residents of the state will be able to purchase the all-new Volt for as low as $24,995 after state and Federal incentives. The 2016 model will start at $33,995 MSRP, including an $825 destination fee (excluding tax, title, license and dealer fees). This is almost $1,200 less than the current generation Volt. "The next generation Chevrolet Volt delivers more technology, the ability to drive further between gas fill ups and now with even more value to our customers. It's what our loyal Volt owners told us they wanted," said Steve Majoros, Director, Chevrolet Marketing. "We are confident we will continue to attract new customers to Volt with the vehicle's product improvements and attractive price." The Volt continues to be a success with the brand with nearly 70 percent of Volt owners trading in a non-GM product or adding to their household fleet in 2014, the highest of any Chevy nameplate. The number one trade-in for the Volt is the Toyota Prius. To date more than 75,000 first generation Volt owners have driven hundreds of millions of EV miles.

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.
