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.

Best Large SUVs of 2024

When it comes down to large SUVs, there's more to consider than price and just how large it is. First, it comes down to what's underneath the skin. Some are built on a truck-like body-on-frame chassis — this would be the traditional, literal definition of an "SUV." Others use car-like, unibody construction, which would make them a crossover. What really matters, though, is how you use them. For most American families, a large three-row crossover is going to be your best bet. They have loads of passenger and cargo space, and deliver superior fuel economy, handling and ride quality than those big traditional SUVs. They're cheaper, too. On the other hand, those traditional large SUVs like the Chevy Tahoe and Ford Expedition are better-suited for more heavy-duty tasks like towing. Most now have bigger third rows than big crossovers, while extended-length versions like the Chevy Suburban have way more cargo capacity behind their third rows than everything but an airport shuttle. As for luxury large SUVs, they fall into those same two categories as well, with American choices mostly being truck-based. The pros and cons of choosing one over another are similar. Below, you will find our list of the best large SUVs broken down into three categories: large family crossover, large traditional SUV and large luxury SUVs, which comprise both construction types.  Best Large Family Crossovers  |  Best Large Traditional SUVs  |  Best Large Luxury SUVs Best Large Family Crossovers 2024 Honda Pilot Why it stands out: Exceptional storage and cargo space; unique second-row functionality; refined ride; versatile and capable TrailSport; advanced AWDCould be better: Subpar acceleration with lackadaisical transmission and engine response; so-so driver assistance tech Read our full 2024 Honda Pilot Review The Honda Pilot was completely redesigned for 2023. It maintains its predecessor's family-friendly packaging and overall focus, but it has injected a welcome sense of style (especially in the TrailSport pictured above) that makes it stand out much better from the big crossover crowd. The Pilot's restrained adornment and classic proportions are refreshing compared to the increasingly busy Kia Telluride, Hyundai Palisade and Subaru Ascent. Let's talk about practicality, though, which is ultimately the Pilot's best attribute.

Recharge Wrap-up: Indianapolis to switch 425 fleet vehicles to EVs, Chevy Corvette provides bat habitats

Indianapolis will deploy 425 battery electric and plug-in hybrid vehicles as part of its municipal fleet by 2016. The fleet will include such cars as the Nissan Leaf, Chevrolet Volt and Ford Fusion Energi. The city will also reduce its overall fleet by 100 vehicles. In all, the revised group - called the "Freedom Fleet" - will save $8.7 million and 2.2 million gallons of gasoline over 10 years. Read more at Hybrid Cars. EVs with longer range would make vehicle-to-home and vehicle-to-grid energy management systems more practical for the US. The idea of using EVs as energy storage for emergencies or times of high grid demand is currently being tested in Japan with Nissan's Leaf-to-Home system. The US is also interested in such capabilities, but the higher average energy use of American households would make larger batteries in EVs ideal for grid storage applications.

The factory, when constructed, will have a capacity of producing batteries for 100,000 cars per year according to the Korean company. The plant will supply batteries for Chinese automakers such as SAIC and Qoros. Construction is expected to be finished by the end of 2015 and LG Chem expects revenue of more than $933 million by 2020. Read more in the press release below. General Motors is using adhesive used in the Chevrolet Corvette Stingray to create habitat for threatened bat species. Artificial bat caves could help alleviate white-nose fungus that leads to diminished bat populations. Leftover adhesive is used to create stalactites in the artificial caves, allowing them more structure to hang from. GM has also provided Volt battery covers to create nesting habitats for bats, which eat harmful insects and help pollinate plants. See the videos and read more in the press release below.
