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.

2014 Chevy Corvette Stingray order guide hits the web

The official debut of the 2014 Chevrolet Corvette Stingray is only part of the excitement for fans of Chevy's virtuoso sportscar. Although we got to see the car and some of its preliminary specs in Detroit and Geneva, there is still no word on pricing and some of the juicier data points we've been waiting for - such as confirmed power output, EPA estimated mileage figures and performance numbers. Until then, CorvetteBlogger has gotten its hands on the order guide for the coupe version of the car - in both base and Z51 iterations - revealing tidbits like standard and optional features and available color combinations.
Some other new details made it onto the order guide, such as our first interior specs for the coupe including slightly less hip room and headroom, more shoulder room and the same amount of legroom. To see the full order guide, head on over to CorvetteBlogger. From what we can gather, it sounds like more information will be revealed on April 25 during a party at the Corvette Museum, and for those sun worshipers patiently waiting for a convertible, it would appear you've got another model year to wait through.

The real costs of keeping a Chevy Volt on the road

The release of the new, 2016 Chevy Volt is sure to bring a surge of used electric vehicles to the market as early adopters trade their older models in. Many of these cars are selling for a fraction of their original price, thanks in part to federal and state incentives that lowered the initial cost to the first owner, which opens these cars up to a whole new class of consumers. While the prices are getting attractive, potential buyers are still hesitant to buy a used EV due to uncertainty about service and repair costs, but there may be some good news on the horizon. The Chevy Volt comes with a battery warranty that is good for at least 8 years and 100,000 miles, but many of the Volts popping up on the market have passed that 100,000-mile mark. The threat of needing a new battery can be a deterrent, especially with some dealers quoting prices as high as $34,000 for a full "drive motor battery replacement." That sum is more than the MSRP of a 2016 model. Some of the fear of EV maintenance and repair comes from the mystery of the individual pieces that make up the drivetrain and charging system. If we take a look at the Volt in terms of analogs to a traditional internal-combustion vehicle, the outlook becomes a little more friendly. The Volt battery pack consists of three lithium-ion modules in a T-shaped arrangement, each of which can be serviced individually. Module 1 is made up of 90 cells and corresponds to GM part number 22954462, which retails for $3,258.33; module 2 is made up of 72 cells and corresponds to GM part number 22954463, which retails for $2,930.00; lastly, module 3 is made up of 125 cells and corresponds to GM part number 22954464, and retails for $4,933.33. These part numbers have been added to the dealer order systems but have not shown up in the distribution centers at this time. Although all three of the modules add up to a fairly large $11,121.66 total and are still on hold for dealer ordering, the good news is that in most cases these battery cell modules do not need to be replaced. There are many other individual pieces mounted on the battery pack that are serviceable, such as the Battery Energy Control Modules (BECM) and the Battery Interface Control Modules (BICM). These modules control and monitor the battery packs and charging system and have been known to fail while the lithium-ion battery cells are not at fault. Some have been replaced under warranty, but if you are stuck buying one they run about $255 a piece for the part.
