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.

Autoblog Podcast #380

Episode #380 of the Autoblog podcast is here, and this week, Dan Roth, Chris Paukert and Seyth Miersma talk about the Fiat-Chrysler five-year plan, the seeming demise of the Nissan Cube, and proposed legislation to require speed limiters with a 68-mph maximum on America's tractor trailers. We start with what's in the garage and finish up with some of your questions, and for those of you who hung with us live on our UStream channel, thanks for taking the time.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging
