2022 GMC Hummer EV No. 001 at Barrett-Jackson brings $2.5 million

This year's Barrett-Jackson auction in Scottsdale, Ariz., played host to a bunch of the first examples of hot new cars: VIN No. 001 of the 2022 GMC Hummer EV, 2022 Cadillac CT5-V Blackwing and CT4-V Blackwing, 2021 Ford Bronco, 2021 Ford Mustang Mach 1 and 2021 Ram 1500 TRX. Every single one of them sold for more than six figures, with all the proceeds of nearly $5 million going to charities, but the big winner was absolutely the Hummer with a hammer price of $2.5 million. The Bronco did nicely, too, with a selling price of $1,075,000. You can see the list of the sale prices from highest to lowest of these first examples below. GMC Hummer EV: $2,500,000 Ford Bronco: $1,075,000 Ford Mustang Mach 1: $500,000 Ram 1500 TRX Launch Edition: $410,000 Cadillac CT5-V Blackwing: $265,000 Cadillac CT4-V Blackwing: $165,000 Despite the Hummer going for $2.5 million, it wasn't the most expensive car to cross the block. That honor goes to a 1966 Shelby Cobra 427 Super Snake that was once owned by Carroll Shelby himself. It sold for $5.5 million, the same price it sold for back in 2007. Nearly as pricey as the Hummer was a restored, numbers-matching 1967 Ferrari 275 GTB/4 that went for $2,475,000. Related video:

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Chevy Tahoe-to-K5 Blazer conversion shop renders Jimmy option

Back in 2019 we told you about a truck that looked like a K5 Chevy Blazer, but was actually a modern late-model Tahoe underneath. It was the product of Arkansas shop Flat Out Autos, which reskinned modern GM full-size SUVs to look like their predecessors. Now, the same shop is planning to release a GMC version, converting Yukons to Jimmys. We were impressed by Flat Out's workmanship, beautifully blending the lines of the Blazer into those of the Tahoe. The result was a cohesive design, not just a panel swap. It clearly required a lot of work, which helped justify the $69,000 price tag, not including the cost of the donor Tahoe. FlatOut Autos GMC Blazer Tahoe reskin 01 View 11 Photos At least one new owner was so impressed that they recently purchased four identical Blazer conversions at once. The quadruplets were all finished in blue with a white roof and all based on brand-new 2020 Tahoes. Obviously, with such demand it was only natural for Flat Out to explore other options. On Facebook the company said it was working on a 1972 version with an eggcrate grille. Now, they've also released a rendering paying homage to the K5 GMC Jimmy. The Jimmy conversion uses the original's quad-headlight face, crosshair grille and GMC badging. Like the Blazer conversion, it adds chrome bumpers and milled door handles while adapting the original's 2-door design to the new truck's 4-door body. The rendering only shows the front three-quarter view, but presumably a new carbon fiber rear door would have to be created as the Blazer's says "Chevrolet" across the back. Flat Out says that all the modern conveniences found on the donor Tahoe will work on the conversion, including parking, blind spot and lane keeping sensors. If you have the coin, it's a great way to have retro style without giving up modern safety and performance. The new Blazer has been disappointing to many fans that had hoped for a Bronco-like SUV. Instead, GM gave us a crossover. The Flat Out conversions might be a good compromise, and expanding it to the GMC brand only makes sense. Obviously there's no requirement to use a GMC Yukon as the donor vehicle for the Jimmy, as it's functionally identical to a Tahoe, but wouldn't you want to keep it in the family? Related Video:
