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: Tesla factory tour video, Obama rejects Keystone XL

Tesla takes us on a 90-second factory tour in a new video. In the footage, we see humans and robots hard at work putting together the electric cars we all know and love. Pieces of the manufacturing process are interspersed with larger shots of the factory floor. In the end, we see the finished product leave the factory and speed off onto a cone course. Check it out in the video above. President Obama has rejected the proposed Keystone XL oil pipeline. After a seven-year review, he says it would not be in America's interest to build the 1,179-mile pipeline to bring oil from Canada's tar sands to the Gulf of Mexico. He cites passing a bipartisan infrastructure bill as a better way to create jobs, says US gas prices are already falling, and that reducing reliance on fossil fuels is a better way toward energy security. "The industry can find a different way to move that oil," says Christine Tezak, energy market analyst at ClearView Energy Partners. "If prices go up, companies will get the oil out."

Donations raised from the auction will help the organization bring student robotics projects to communities in need of greater science, technology, engineering and math (STEM) education representation. "The Volt exemplifies technology, and behind the next-generation Chevrolet Volt is a diverse team of engineers who understand the power of science and math," says Chevrolet Marketing Director Steve Majoros. "FIRST brings science and math alive outside the classroom, just like we are bringing it alive on the road." Read more from Chevrolet. Nissan has been ranked among the top five percent of global corporations in the Carbon Disclosure Project's (CDP) 2015 Climate Change Report. Nissan scored a perfect 100 points in CDP's Climate Disclosure Leadership Index. Nissan's successful Leaf EV, as well as its efforts to reduce well-to-wheel CO2 emissions by 90 percent by 2050, earned the automaker its high marks. "Nissan is providing customers with innovative products and promoting effective use of energy and resource by increasing sourcing diversity, such as with renewable energy and recycled materials," says Nissan Corporate Vice President Joji Tagawa. "We will continue our activities to achieve our environmental philosophy of 'a Symbiosis of People, Vehicles and Nature.'" Read more in the press release below.

Chevrolet considering midsize crossover to slot between Traverse and Equinox

Crossovers are the new hotness, and automakers are looking to cash in by offering a size and shape for every customer. With Chevrolet's debut of the new 2018 Traverse in Detroit, which grew ever so slightly compared to the first-generation model, there is now a midsize-crossover-sized hole between the three-row Traverse and the compact Equinox. When asked about that obvious space, a Chevrolet spokesperson told us the company is looking into the possibility of expanding its crossover lineup. It should be a relatively simple thing to do, since all it would take is reskinning and rechristening the GMC Acadia with a bow tie, and we all know how much GM loves platform sharing. Although they're now different sizes, the new Acadia and Traverse still use the same platform; the Acadia is now on a short-wheelbase version of the C1XX while the Traverse uses long-wheelbase C1XX parts. A short-wheelbase Chevy built on the C1XX likely would be differentiated visually from both the Acadia and the larger Traverse. It may seem like flooding the lineup with more and more models would cannibalize sales of existing ones, but Chevrolet said it would rather have customers stay within the brand rather than going to another automaker. There have been whispers that some form of the Blazer name (possibly TrailBlazer) may make a return on a midsizer, but if it does don't expect an old-school body-on-frame SUV like the old one. In the end, if Chevy builds it, customers will come. Related Video:
