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.

GM recalls Cadillac ATS and Chevy Impala for separate issues

The National Highway Traffic Safety Administration added two recalls from General Motors in the government organization's daily update of safety campaigns. Both were for failing to meet Federal Motor Vehicle Safety Standards but for completely separate reasons. The larger recall covers 58,698 units of the 2013-2015 Cadillac ATS, but it doesn't really carry huge safety concerns. In vehicles produced between April 25, 2012, and February 9, 2015, the controls for the tilt and slide of the moonroof are not recessed enough, as required by federal law. According to NHTSA, it's possible that someone could inadvertently activate the auto-close for the roof panel, which the agency claims increases "the risk of personal injury." Dealers will install a new trim plate that will add the necessary clearance. The other campaign covers 1,177 examples of the 2014 Chevrolet Impala from between November 15, 2012, and May 27, 2014. However, this is actually a repeat of a previous recall on the Chevy and the Cadillac XTS from 2014. The affected Impalas here "were remedied incorrectly" under the earlier campaign, according to NHTSA. On these sedans, it's possible the electronic parking brake might not fully disengage and still remain in some contact with the rotor, which is in violation of federal rules. The fault can cause excessive heat from the brakes that could potentially lead to a fire, according to NHTSA. To fix the problem, dealers will reprogram the electronic parking brake control module.

In the affected vehicles, the power-operated roof panels auto-close when the non-recessed "Slide" or "Tilt" switches are pressed. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standards (FMVSS) No.

12 new cars that will never go out of style

Some cars never go out of style. It’s rare, but it happens. They get old. They get depreciated. But they never stop looking cool.  Some might call them modern or instant classics. Within a few years theyÂ’re no longer the latest and greatest, no longer the flavor of the month, but they remain special. Eternally special. Timeless.  These cars arenÂ’t necessarily going to be worth a fortune someday. However, some may not depreciate as rapidly or as far as other models. But thatÂ’s not what weÂ’re talking about here. These are the cars that enthusiasts will always find desirable from the curbside. TheyÂ’re the cars you end up shopping on eBay late at night 10 years later because you canÂ’t get them out of your head. TheyÂ’re the cars that will forever excite you when you spot a clean one in traffic or in a parking lot.  There are plenty of recent examples over the past couple of decades that could count as instant design classics. But then we got to thinking, what 2021 models will be forever cool to stare at? Which new cars and trucks on sale today will we be shopping on eBay late at night in the 2030s? We kept supercars and other ultra-expensive cars off the list to keep things within the realm of attainability, and ended up with 12 total cars. Lexus LC WeÂ’re not applying a numerical ranking to any of the cars on this list, but if we were, the Lexus LC would be No. 1. There isnÂ’t another car design out there that can stir our emotions the way an LC can when itÂ’s just standing still. This car is a concept design come true in the most beautiful of ways, and itÂ’s a shoo-in winner for Concours events decades into the future. All of this heaping praise, and we havenÂ’t even gotten to the LC 500Â’s intoxicating 5.0-liter V8. It doesnÂ’t win drag races. It wonÂ’t be the fastest around the track against any similarly-priced competition. But none of that matters. ItÂ’s quite possibly the best car you can buy new, and that says it all when it comes to the LC. Chevrolet Corvette It might not be the stunner that the Lexus LC is, but the new C8 Corvette is and will always be a special vehicle. ItÂ’s the first mid-engine Corvette, which instantly cements it into an automotive hall of fame section of sorts. All of the performance stats and specs are there to back up its supercar-like looks, and it remains the best performance bargain on sale today.
