First privately owned Corvette Stingray blitzes 1/4 mile in 12.23 at 114.88 mph

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.
Equipped with the Z51 package and a six-speed automatic transmission, not only does the C7 run a solid time, but it does so with little to no drama. That won't last though, as Hennessey will likely return it to its owner with far more power - we just hope they show a drag run of the completed product. Take a look below to watch the C7's 12.23-second run on video.

Best new convertibles for 2024 and 2025

If you’re here, then youÂ’re already in the right mindset. Convertibles rule, and we have all the best convertibles listed for you further below. Driving around with the top off is an experience you need to live to fall in love with. When the weatherÂ’s right, youÂ’re on a proper bit of road, and the car youÂ’re in is a good one, few automotive experiences can top it. The experience is extra special when you have a musical exhaust note filtering directly into your ears and echoing off the landscape around you. And while rolling the windows down and opening a moonroof can get you part of the way there, it's nothing like feeling the wind wash over you with absolutely no roof overhead. The downsides can be just as harsh as the upsides when youÂ’re in the wrong conditions, though. Convertibles are typically worse to live with in cold climates, and driving around with the top up frequently means you might be subject to more road noise and worse visibility than an equivalent coupe. And when it comes to pure performance, convertibles are inherently compromised from a weight and structural rigidity perspective. All that said, we still think the upsides outweigh the compromises if your number one objective is to simply have fun. ItÂ’s a good thing then that there are a ton of great convertibles for sale these days. And no, the list of possibilities isnÂ’t as long as it used to be. Long-running standbys like the Mercedes-Benz E-Class and C-Class Convertibles are gone (replaced by the one CLE-Class). And so are others like the Audi TT Roadster, Fiat 124 Spider and Nissan Z Roadster. Nevertheless, opportunities abound from the ultra-cheap and fun, to physics-defying supercars and everything else in between. WeÂ’ll give you options for which new convertibles we think are the best below, so read on to find out.   Mazda MX-5 Miata Pros: Lightweight and compact; great engine and transmission combo; one of the most raw and pure driving experiences out thereCons: Not great for tall people; infotainment is dated; tiny trunk Read our Mazda MX-5 Miata Review Miata is always the answer, right? In this case, that rings even more true than usual. In fact, you could stop reading this list right here and go buy a Miata and youÂ’d likely be just as happy driving it around as you would be in any of the more expensive offerings that follow. ThatÂ’s just the magic of the MX-5.

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.
