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.

Recharge Wrap-up: Chevy Volt CarPlay video, Tesla Supercharger importance

A video demonstrates Apple CarPlay on the touch display in the next-generation Chevrolet Volt. The Volt's eight-inch (bigger than an iPad Mini) capacitive display is capable of putting Siri and your iPhone apps and right at your fingertips. It's "the best CarPlay display I've seen," says the user in the video. In case you're not in the market for a new Volt, 9to5Mac offers some of its favorite aftermarket CarPlay screens.

Teslarati's Electric Jen talks about purchasing a Model S, being assured by both Tesla employees and the map of planned Supercharger sites that one would be built along an important route for her. With the construction being pushed back, it made visiting family tricky. "As if owning such a grand car isn't embarrassing enough, asking for a ride to drop off and pick up said car because you can't make it home without charging really made me feel awkward," she says. "You see, one single charging location can mean the world to some people," Jen adds. Read the whole article at Teslarati. Tesla once had considered creating mobile range extender trailers for the Model S. Elon Musk touched upon the abandoned idea during his visit to Paris. While Tesla ultimately dismissed the concept, Nomadic Power has taken the opportunity to hitch their product onto the Tesla brand. "We are delighted, that Tesla Motors' CEO Elon Musk is thinking about a concept like ours for even more extending the range of the Tesla models," says Nomadic Power's CEO Manfred Baumgaertner. He adds, "This confirms our approach to build a long distance mobility provider for all electric vehicles on the market." If you say so, Baumgaertner.

When the batteries have degraded to the point that they're no longer suitable for use on the road, they still have a significant capacity that can be used for other purposes. Still useful for stationary storage, they can be used to support charging sites in order to allow for faster charging. The stationary batteries can charge slowly at the site, but then offer up the juice in a hurry when it's needed for a vehicle. Read more from Renault.

Petrolicious profiles one man and his duo of '64 Impalas

Restoring any vintage car is a labor of love. In the end, the investment of time and money is often more than the vehicle is realistically worth on the open market. Deciding to take all of that work on yourself doesn't make things any easier, but it can only increase your connection to the project. Don Rogers, the subject of the latest video from Petrolicious, shows this passion perfectly with his duo of 1964 Chevrolet Impalas – a hardtop and convertible. Both of these Chevys had been sitting for years before Rogers got his talented hands on them, and he did all of the work himself. Now, driving the pair is therapy for him, and he's not worried about anything breaking because he knows he can put it back together. Rogers says he enjoys wrenching on his vehicles even more than going to shows. Doing your own work comes with advantages, like tailoring a project's look to your preferences. It's not original, but Rogers used the crimson interior color from a '59 Impala on his convertible to make the interior pop with the top down. Rogers is undoubtedly a talented builder, and his work is worth checking out in the latest from Petrolicious. Related Video:
