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.

New auto loans could soon extend out to 84 months

Cars and trucks are more expensive than ever before. In order to boost sales and help consumers afford new vehicles, automakers are offering longer and longer terms for auto loans. This past week, Bloomberg reported that FCA's Ram Trucks division is currently offering the longest loans. Some stretch to 73 months. Jeep, Fiat and Chevy aren't far behind. More noteworthy is that we'll likely soon see lenders moving from 73-month to 84-month loans. That's seven years worth of interest. More than two-thirds of US auto sales come from light trucks like the Ford F-150, Chevy Silverado and Ram 1500. The average transaction price of a new vehicle is well over $30,000. It's not difficult to spec out a heavily-optioned truck up to $60,000. Vehicles depreciate from the moment they roll off a dealer lot, and these six or seven-year loans could hurt consumers and lenders both in the long run. The U.S. Senate voted last week to kill rules that would prevent discriminatory auto lending. These Obama-era guidelines were meant to curtail lenders who offered higher loans based on race, religion, sex or national origin.

2016 Chevy Volt sneak peek at CES

Here it is, folks – your first real glimpse at the 2016 Chevrolet Volt. The gasoline-electric sedan will officially debut at the Detroit Auto Show next week, but Chevy gave us a sneak peek of its redesigned Volt at a media event in Las Vegas late Sunday, as part of its CES festivities. There isn't a ton to see here, and sorry about the low quality video (and for us not standing front and center during the reveal). But we can clearly see the car's redesigned front fascia – something recently previewed at a fan event in Los Angeles. For another view, check out a high-res photo of the new Volt from our friends at The Verge, here. Chevy even tweeted a photo of the Volt's new nose on its official Volt Twitter account, which you can see below. The automaker didn't divulge any details about its new Volt, but we already know quite a bit. For starters, the Volt will use a new, 1.5-liter gasoline engine and won't require premium fuel. It'll have more EV range and a bigger battery, too. We'll have a whole mess of information when the 2016 Volt is fully revealed in Detroit in about one week's time. In the meantime, here are some more looks at the Volt, courtesy of the Twitterverse. We're so excited about #NextGenVolt we brought it out early at #CES2015!
