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.

How Chevy used popular Instagram user to promote 2016 Volt

A picture is worth a thousand words. When it comes to Chevrolet and its Volt extended-range plug-in, the automaker is hoping pictures can be turned into a few more buyers. The company extended a little love to one popular social-media practitioner to see if the trick works. Former biochemical engineer Kevin Lu started his Instagram account a couple of years ago during a road trip, and the quality of his shots has attracted about 181,000 followers. With that popularity in mind, Chevy brought Lu up to Detroit to check out the unveiling of the next-generation Volt at the Detroit Auto Show last month. Lu also got to see the Detroit-Hamtramck Assembly factory where the Volt is built, Automotive News reports. As for the next-gen Volt, Chevy says a more efficient powertrain and lighter battery help give the car an all-electric range of up to 50 miles and a total driving distance of more than 400 miles. Chevy also touts the model's streamlined grille and (tight) seating for three in the rear. General Motors hopes a combination of those improvements and exposure from sources such as Lu and his Instagram account (and some sleepy ads, apparently) revitalize sales of the model. Last year, Volt sales fell 19 percent to 18,805 units.

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.
