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.

Impala SS vs. Marauder: Recalling Detroit’s muscle sedans 

Impala SS vs. Marauder — it was comparo that only really happened in theory. ChevyÂ’s muscle sedan ran from 1994-96, while MercuryÂ’s answer arrived in 2003 and only lasted until 2004. TheyÂ’re linked inextricably, as there were few options for powerful American sedans during that milquetoast period for enthusiasts. The debate was reignited recently among Autoblog editors when a pristine 1996 Chevy Impala SS with just 2,173 miles on the odometer hit the market on Bring a Trailer. Most of the staff favored the Impala for its sinister looks and said that it lived up to its billing as a legit muscle car. Nearly two-thirds of you agree. We ran an unscientific Twitter poll that generated 851 votes, 63.9 percent of which backed the Impala. Muscle sedans, take your pick: — Greg Migliore (@GregMigliore) April 14, 2020 Then and now enthusiasts felt the Impala was a more complete execution with guts. The Marauder, despite coming along later, felt more hacked together, according to prevailing sentiments. Why? On purpose and on paper theyÂ’re similar. The ImpalaÂ’s 5.7-liter LT1 V8 making 260 horsepower and 330 pound-feet of torque was impressive for a two-ton sedan in the mid-Â’90s. The Marauder was actually more powerful — its 4.6-liter V8 was rated at 302 hp and 318 lb-ft. The ImpalaÂ’s engine was also used in the C4 Corvette. The MarauderÂ’s mill was shared with the Mustang Mach 1. You can see why they resonated so deeply with Boomers longing for a bygone era and also captured the attention of coming-of-age Gen Xers. Car and DriverÂ’s staff gave the Marauder a lukewarm review back in ‘03, citing its solid handling and features, yet knocking the sedan for being slow off the line. In a Hemmings article appropriately called “Autopsy” from 2004, the ImpalaÂ’s stronger low-end torque and smooth shifting transmission earned praise, separating it from the more sluggish Mercury. All of this was captured in the carsÂ’ acceleration times, highlighting metrically the differences in their character. The Impala hit 60 miles per hour in 6.5 seconds, while the Marauder was a half-second slower, according to C/D testing. Other sites have them closer together, which reinforces the premise it really was the little things that separated these muscle cars. Both made the most of their genetics, riding on ancient platforms (FordÂ’s Panther and General MotorsÂ’ B-body) that preceded these cars by decades. Both had iconic names.

Chevy donates first 2016 COPO Camaro to United Way

Want to get your hands on the first new COPO Camaro? Scottsdale will be the place to be this weekend. That's where Barrett-Jackson will auction off the drag-racing muscle car with the serial number 2016COPO001. The example on the docket is the very same show car that Chevy revealed at the SEMA show just a couple of months ago. Like every new COPO Camaro, it's based on the new sixth-generation coupe and packs an array of drag-racing upgrades. Those include a three-speed automatic transmission, solid rear axle, and adjustable suspension. While Chevy will offer the new COPO Camaro with a choice of three engines, this particular example packs the 5.7-liter supercharged V8, as well as a unique red and black livery designed by Chevy drag racing driver Courtney Force. 100 percent of the proceeds from the sale are destined to go to United Way, following previous examples that benefited wounded veterans. You can bet it will raise a pretty penny at auction, but if you miss this one, of course there will be more. Just don't wait around too long as the Bowtie brand will only make 69 of them this year. 2016 COPO Camaro No. 1 Sale to Benefit United Way Courtney Force designed show car to be auctioned for United Way 2016-01-26 DETROIT – Chevrolet will auction off the first, sixth generation 2016 COPO Camaro race car to raise money for United Way. The purpose-built COPO Camaro, serial number 2016COPO001, will be sold on Friday, Jan. 29, at the Barrett-Jackson Scottsdale auction. All proceeds of the winning bid will benefit United Way. "This is a special opportunity to purchase the first of the sixth generation, 2016 COPO Camaro while also helping such a great cause," said Jim Campbell, U.S. vice president of Performance Vehicles and Motorsports. The COPO is a powerful, purpose-built Camaro designed to race in NHRA Stock Eliminator class. The COPO Camaro legacy continues with an all-new sixth-generation version. This modern-looking machine infuses legendary COPO performance with the modern, lighter and stronger design of the 2016 Camaro. Chevrolet introduced the sixth generation COPO Camaro No. 001 last November at the SEMA Show and includes a personalized look created by Chevrolet and NHRA Funny Car driver Courtney Force. It features a Red Hot exterior color with Courtney Force-signature graphics and red-accented grille trim. "I was extremely honored to work with Chevrolet and help design the 2016 COPO Camaro," said Courtney Force.
