Corvette + fireworks = so much glory

You might think that those of us making our living by reviewing cars, think critically about the cars we're driving most of the time. It could be that I'm an underachiever, but that's not the case with me. In fact, unless I'm set to the review task, I typically think about the cars in front of and around me more frequently. That's because a) you never know what you're going to see out there, and b) all of them could be out to bump/scratch/tailgate/crash me out. You can never be too careful. Such was the case when I was driving a 2015 Chevy Corvette earlier this week. I'd already had my fun finding the edges of grip on a river road in the car, the night before; on the morning in question I was just trying to get to work. But while scanning the suburban streets for potential dangers to the 'Vette's neat-o Daytona Sunrise orange paint, I spied a XXL-sized fireworks tent in an empty parking lot. Oh right, I remembered, 4th of July weekend. That obvious bit of observation lead to a chain of thought along these lines: "We should do something with this car for the 4th" ... "Too bad I have to give it back tomorrow." ... "Wonder if I could do a quick video?" ... "Wonder if I can set off a bunch of fireworks in slow-mo for a video?" The result, well, I won't call it genius, but I will say that I remember why every kid loves fireworks. And I will call it glorious. Happy 4th, y'all.

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.

Chevy Bolt name just might get through US trademark office

UPDATE: GM told AutoblogGreen on June 1 that, "Our Chevrolet Legal team has been working closely with the USPT on the Chevrolet Bolt trademark. As of last week, our legal staff received consent from Yamaha to use the Bolt name. According to our legal team, our USPT application is back to active status." Also, it appears that GM has further trademarked Bolt EV and Chevrolet Bolt EV. Chevy wants to sell a 200-mile electric vehicle for around $35,000 in a few years. The Detroit automaker wants to call that car the Bolt, not to be confused with the company's other plug-in, the Chevy Volt. Unless something changes, the United States Patent and Trademark Office (USPTO) is going to crush GM's Bolt-flavored dreams. The USPTO has suspended GM's trademark application. The USPTO said in its suspension that there was a "likelihood of confusion" with another Bolt trademark, No. 4429759, which applies to a Bolt trademark filed by Yamaha on August 09, 2012. That's well before GM's effort to trademark the Bolt name in 2014. GM's application will remain suspended, the USPTO said, "until the earlier-filed referenced application(s) is either registered or abandoned." Maybe GM will use this setback to respond to the many criticisms of the Bolt name we've heard since it was first announced. There is another page on the USPTO's website that says GM's Bolt application is still live, but we assume that just hasn't been updated yet. Related Video:
