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.

VW, Rivian, Nissan, BMW, Genesis, Audi and Volvo lose EV tax credits starting tomorrow

The U.S. Treasury said Monday that Volkswagen, BMW, Nissan, Rivian, Hyundai and Volvo electric vehicles will lose access to a $7,500 tax credit under new battery sourcing rules. The Treasury said the new requirements effective Tuesday will also cut by half credits for the Tesla Model 3 Standard Range Rear Wheel Drive to $3,750 but other Tesla models will retain the full $7,500 credit. Vehicles losing credits Tuesday are the BMW 330e, BMW X5 xDrive45e, Genesis Electrified GV70, Nissan Leaf , Rivian R1S and R1T, Volkswagen ID.4 as well as the plug-in hybrid electric Audi Q5 TFSI e Quattro and plug-in hybrid (PHEV) electric Volvo S60. The Swedish carmaker is 82%-owned by China’s Zhejiang Geely Holding Group. The rules are aimed at weaning the United States off dependence on China for EV battery supply chains and are part of President Joe Biden's effort to make 50% of U.S. new vehicle sales by 2030 EVs or PHEVs. Hyundai said in a statement it was committed to its long-range EV plans and that it "will utilize key provisions in the Inflation Reduction Act to accelerate the transition to electrification." Rivian declined to comment and the other automakers could not immediately be reached for comment. Treasury also disclosed General Motors electric Chevrolet Bolt and Bolt EUV will qualify for the full $7,500 tax credit. GM said earlier it expected at least some of its EVS would qualify for the $7,500 tax credit under the new rules, including the 2023 Cadillac Lyriq and forthcoming Chevrolet Equinox EV SUV and Blazer EV SUV. Treasury said all GM EVs will qualify. Earlier, Ford Motor and Chrysler-parent Stellantis said most of their electric and PHEV models would see tax credits halved to $3,750 on April 18. Treasury confirmed the automakers' calculations. The rules were announced last month and mandated by Congress in August as part of the $430 billion Inflation Reduction Act (IRA). The IRA requires 50% of the value of battery components be produced or assembled in North America to qualify for $3,750, and 40% of the value of critical minerals sourced from the United States or a free trade partner for a $3,750 credit. The law required vehicles to be assembled in North America to qualify for any tax credits, which in August eliminated nearly 70% of eligible models and on Jan. 1 new price caps and limits on buyers income took effect.

GM learning from current Chevy Volt owners as it works on next-gen model

Details of the second-generation Chevrolet Volt extended-range plug-in hybrid are coming in at a trickle, and the latest is that the 2016 model-year Volt will be improved in all meaningful areas, including performance and all-electric range, says General Motors powertrain director Larry Nitz. 60 percent of Volt customers only charge using a standard 110 outlet. Nitz was speaking to Autoline After Hours about the current and future Volt. He said that GM has been tracking Volt driving habits and found that about two-thirds of the Volts' collective miles are driven in electric mode, and that 81 percent of all Volt trips were done in pure EV mode. Additionally, Volt drivers plug the car in 10 times each week, on average. Nitz also said 82 percent of the Volt's commuting miles are coming from the plug instead of the gas tank. Oh, and 60 percent of Volt customers only charge using a standard 110 outlet. Last month, GM released a teaser shot of the 2016 Volt (above) and said the car would make its worldwide debut at the 2015 North American International Auto Show next January. Earlier this year, the Volt was reported to be getting a new chassis for the upcoming version. The Volt could use a bit of new life. Through August, Volt sales were down 12 percent from a year earlier to 13,146 units, and sales plunged 25 percent alone. That compares unfavorably to the Nissan Leaf battery-electric vehicle, whose 2014 sales have jumped 34 percent to almost 19,000 units. You can see Nitz dish the goods in the video below (Volt comments start at around minute 15).
