Corvette Stingray Shooting Brake under consideration by Callaway [w/poll]

Callaway has released a few renderings of a design study for a shooting brake version of the C7 Chevrolet Corvette Stingray. The company says it wants to create a long-roof version of America's sports car to offer buyers more interior room and a vehicle with "unique style." The company says it will use structural carbon fiber for the new body bits, which suggests the conversion shouldn't add too much more weight to the Corvette. Along with a few mechanical tweaks, the Callaway Corvette Stingray AeroWagon could breeze past the 200 miles per hour barrier.
Provided that they get enough interest, Callaway estimates they will be able to effect the changes on the Chevrolet for around $15,000, and says the conversion work should be available through its network of dealers. You can check out the brief press release below for more information, or head over to the Callaway site to plunk down a deposit - but before you do, we want to know... do you find this C7 wagon interesting?

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

UAW strike's three-pronged attack focuses on popular midsize trucks, SUVs

The United Auto Workers announced at midnight last night that they would begin targeted strikes at Ford's Michigan Assembly, Stellantis' Toledo Assembly and GM's Wentzville Assembly — all three home to midsize pickups and, in the case of Toledo and Michigan, popular midsize SUVs.  The Ford Ranger, Jeep Gladiator (just updated for 2024), Chevy Colorado and GMC Canyon are all built on lines that have been shut down by the strike. The Ford Bronco and Jeep Wrangler, which share fundamental underpinnings with the Ranger and Gladiator, respectively, are also in on the party. GM's Wentzville Assembly also builds the GMC Savana and Chevy Express vans, neither of which is a big player in the retail market. While midsize pickups may not move in the quantities we see from the half-ton segment, all of these are fairly high-volume models. Ford sold nearly 120,000 Broncos along with more than 55,000 Rangers in 2022; Wrangler and Gladiator combined for nearly 260,000 units last year (181,000 of those were Wranglers) and the Colorado/Canyon represented more than 117,000 sales for General Motors. Throw in the nearly 80,000 units for Chevrolet Express and GMC Savana, and production from these facilities equated to more than 500,000 units sold in 2022.  Ford has been struggling since launch to deliver its wildly popular Bronco to waiting enthusiasts. With supply woes largely easing last year, the company caught up to a great deal of its pre-existing demand, but lingering supply chain and quality control issues have continued to plague the manufacturer even as general constraints have eased. Even earlier this year, Ford said it was selling every unit it could produce. The Ranger, freshly redesigned for the U.S. market, is still getting its feet wet.  Jeep likewise has been on a tear. Sales of the 4x4 have remained so steady that the Wrangler 4xe became the country's best-selling plug-in hybrid vehicle pretty much by accident. Jeep just formally confirmed this week that a 4xe variant of the Gladiator pickup is on the way by 2025 — and they said you couldn't sell hybrids to truck and SUV buyers.  At GM, meanwhile, the Colorado and Canyon are sporting fresh redesigns for the 2023 model year, with production of both still ramping up. And while the Chevy Express and GMC Savana vans may not be popular consumer models, GM still sold more than 77,000 of them last year combined.  Related video: Plants/Manufacturing UAW/Unions Chevrolet Ford GMC Jeep Truck SUV
