Huge, pricey trucks haul jobs and profits for the Detroit Three

DECATUR, Texas — Mickey McMaster is on his 12th pickup truck. The 61-year old farm equipment dealer in Decatur, Texas, two weeks ago treated himself to a 2019 GMC Denali for around $69,000 — a reward for long hours at work. "For me this is the Cadillac of trucks, it's a real luxury vehicle," McMaster said. "I've worked my way up to afford a truck like this and it shows that I've earned it." McMaster is the kind of customer General Motors Co is banking on as it plans to add 1,000 jobs at a plant in Flint, Michigan that will build a new generation of its largest pickups. Demand from Texas and other heartland states for big pick-ups is providing a lifeline to many workers the No. 1 U.S. automaker is laying off at plants elsewhere. The Detroit Three automakers and thousands of their U.S. workers are counting on customers like McMaster to keep buying bigger and more luxurious pickup trucks even if overall U.S. vehicle demand weakens this year, as most analysts predict. At Flint, GM will build a new generation of its heavy-duty Chevrolet Silverado and GMC Sierras, including luxury models that are some of the most profitable vehicles on the planet. GM, Ford Motor Co and Fiat Chrysler Automobiles NV's Ram division own the segment and are each doubling down with new or redesigned models launching this year. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday celebrated the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. At the same time that GM is laying off thousands of U.S. workers and planning to shutter five North American factories, Flint is hiring. The plant runs on three daily shifts, six days a week. As the new model's assembly system ramps up, the plant's capacity will increase by more than 25 percent, plant manager Mike Perez told Reuters. The Flint plant plans to add 1,000 workers, more than half of the 1,500 factory workers who have asked to transfer from plants GM has targeted for shutdown as part of CEO Mary Barra's restructuring plan. "We're bringing in 50 to 100 people every week," said Perez. Workers last week were still finishing the job of retooling the Flint factory to build the new heavy-duty trucks as part of a $1.5 billion investment project.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.

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.
