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: U of M wins Solar Challenge, family attempts record-breaking e-bike ride

The University of Michigan Solar Car Team has won the 2014 American Solar Challenge. It is the team's eighth national championship, its fifth in a row, and its first using Siemens' product lifecycle management (PLM) software. The race took place over 1,722 miles and seven days traveling across eight states. The team's car, called "Quantum," outpaced the nearest competitor by four hours. Looking forward, Michigan Solar Car Project Manager Pavan Naik says, "The switch to Siemens tools will give us the ability to model and simulate everything and truly allow us to optimize the performance of our new vehicle. As we start on our quest to win the World Solar Challenge in 2015, we'll be leveraging a full complement of PLM solutions." Read more in the press release below. The EcoCar3 competition, in which teams will convert Chevrolet Camaros into hybrid electric cars, begins in September. The various college teams will have four years to lessen the car's environmental impact as much as possible while maintaining performance and, of course, that cool Camaro design. EcoCar3, which is put on by the US Department of Energy and General Motors, kicks off with a workshop in Novi, Michigan from September 16 - 18. Read more at the DOE website at the dedicated EcoCar3 site or watch the announcement video at our previous post. Zap and Jonway Auto are shifting to a high rate of EV production. Zap already has two lines creating the Urbee EV to met demand, and is switching over a third to make electric minivans and SUVs. The company aims to produce 30,000 EVs by 2015 for the Chinese market. Zap says it has a backlog of 25,000 Urbee orders. Read more in the press release below. A family of four hopes to make a world record-breaking, 6,000-mile electric bike journey this fall. The family, which recently drove from Argentina to Montana in a pickup with a camper, will ride from Montana to Maine, then down the East Coast to Florida in an attempt to break the record for longest electric bicycle ride. They'll use two bikes. The Father, Thomas, will ride one of the bikes carrying one of the children, while the rest of the family rides in a support vehicle, with the mother, Dylan, riding the second bike when they can find others to drive. They have started a crowdfunding campaign for some of the equipment needed to document the trip. See the video below or read more at Treehugger.
