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.

2013 Chevy COPO Camaro announced with two new engines and manual option

Chevrolet is following up the 2012 COPO Camaro with another limited run of the drag-strip-ready production car for 2013. Ditching the superchargers, the 2013 COPO Camaro can only be equipped with one of three naturally aspirated V8 engines, and other new features include the option of a manual transmission, new front springs, some minor styling changes and a lower starting price of $86,000. All cars are designed to abide by the rules of the NHRA's Stock Eliminator or Super Stock classifications, depending on in which series buyers wish to enter their Chevrolet Camaro.
Returning for 2013 is the 427-cubic-inch V8 producing 425 horsepower, but the new engines include a 325-hp 350-CID V8 and a 375-hp 396-CID V8. Buyers can select to purchase all three engines, and each will be matched with the sequence number of that car; the track-only COPO cars will not have vehicle identification numbers and can't be registered for street use.
Chevrolet is also offering unique enthusiast-specific options such as a COPO Build Book and the opportunity for owners to help assemble their car's engine at the Chevrolet Performance Build Center in Wixom, MI.

December sales for Chevy Volt, Nissan Leaf are what you expected

It was another month of as-expected sales for the two pioneering plug-in vehicles in the US. The Nissan Leaf is basically treading water and the new-generation Chevy Volt is getting back to old habits with a big increase in sales compared to where the car was last year. It wasn't a surprising month, but there wasn't any reason to expect a surprise. In fact, we don't suspect this trend to veer too far from where it's at right now until gas prices shoot up or Nissan introduces a new Leaf. Neither of those things is likely to happen any time soon. Let's start with the mediocre news. Nissan reported today that Leaf sales for December 2015 totaled 1,347 units. That's a 56.6-percent drop from where the Leaf was a year ago, and contributed to the all-electric vehicle's 42.8-percent drop in 2015 sales compared to 2014. This past year, 17,269 people bought Leafs, down from 30,200 who did so in 2014. The Volt sold 2,114 copies last month, bringing the plug-in hybrids 2015 total up to 15,393. That's an 18.1 percent drop from the 18,805 Volts sold in 2014. We shouldn't see the past year as a total flop for the Volt, though, since the much-improved second-generation model was introduced late in the year. In fact, if we just look at December 2015 and compare it to the last month of 2014, we see the Volt was able to post a 41.9-percent increase. It'll be quite fun to see where the Volt's numbers go in 2016. As you probably know, we'll have our complete wrap up of green car sales for you soon. Stay tuned.
