It's time for Corvette to attack Porsche

For most of its existence, Porsche was a smug little sports car company with a fairly limited lineup and small but steady sales. Any time the company strayed from its air-cooled, rear engine formula, the purists would turn their noses. The 944? The 948? "Not a proper Porsche," they'd sniff. And then came the greatest sin of them all: the Cayenne. To the purists, this was treason. Porsche making an SUV? Horrors! Of course, you all know how it turned out. Porsche grew to be a profit-generating juggernaut within the Volkswagen Group. And since one SUV wasn't enough they added another, the Macan. By the end of the decade Porsche will have quadrupled its global sales. You have to wonder what else it has up its sleeve. Couldn't this be a lesson for General Motors? It has a terrific sports car brand in Corvette. In fact, it's arguably the most iconic brand within GM's full-line portfolio. But for its entire existence that brand has been locked up within Chevrolet. Maybe it's time for GM to treat Corvette as a stand-alone company. Maybe it's time for GM to unlock that brand and treat Corvette as a stand-alone company. A Corvette SUV could be a killer first step. Since Porsche only makes two SUVs, maybe Corvette could make three. Small, medium, and large. And just as Porsche has the Panamera, an executive sedan from team Corvette could become an instant "gotta-have" for the yacht-buying jet set. Of course, the Corvette purists will cringe. And the biggest hue and cry will come from Chevrolet's US dealers. That's why the best place to launch the new Corvette brand would be far away from those franchisees: in China. Chinese consumers have no pre-conceived ideas that 'Vettes can only be sold in Chevy stores. And Chinese enthusiasts very much admire Corvette's historic pedigree. You've no doubt read about how Chinese authorities are cracking down on conspicuous consumption. That makes the timing even better. Corvette's selling point has always been that it is an amazing bargain for the performance you get. What a perfect way to undercut Porsche. In fact, pairing the Corvette brand with Cadillac in China could be just the shot in the arm that Cadillac's Chinese dealers need. Despite having very competitive cars, Cadillac lags far behind Audi, Mercedes, and BMW. What Cadillac dealers need is a lot more showroom traffic. And a jaw dropping lineup of Corvette-branded vehicles could bring in throngs of buyers.

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.

LG Chem's troubled Chevy Volt battery plant hiring once again

The Michigan battery plant known for paying its workers to do nothing has turned things around and is now hiring more workers, specifically to do something. South Korea-based LG Chem, which runs the factory to supply the Chevrolet Volt extended-range plug-in vehicle with its lithium-ion batteries, held a job fair recently to bring on 40 new employees in order to meet higher battery demand, according to WZZM, the ABC affiliate for Grand Rapids, MI. The LG Chem factory is in Holland, MI, about 30 miles west of Grand Rapids, and it made its first batteries last year. Prior to that, though, the factory gained notoriety after a US Department of Energy (DOE) probe found that workers there were getting paid to do, well, nothing. That's because demand for the battery packs was so low that it cost less for the plant to sit idle. The DOE was conducting the probe because of its financial grant to LG Chem. But that was then and today is today. LG Chem is looking to ramp up production in advance of the second-generation Volt. That 2016 model-year version is said to have a longer all-electric range and better performance and will ride on a new chassis, but few official details have surfaced. We will know more when we get our first look at the car at the Detroit Auto Show in January.
