Recharge Wrap-up: Panasonic, Tesla on Gigafactory deal?

Bentley has been awarded the Carbon Trust Standard for reductions of carbon, water use and waste production in manufacturing. The Carbon Trust is an organization that helps groups such as businesses and governments reduce carbon emissions, use of energy and resources, and waste output. From 2011 to 2013, Bentley reduced CO2 emissions by 16 percent per car manufactured, curtailed water use by 35.7 percent, and saw significant waste reductions. Darran Messem of Carbon trust says, "Bentley is clearly passionate about continuing to improve its environmental performance, which is reflected by the fact the company has consistently invested in new technology."

The organization will use the range-extended electric cars in its efforts to help MBA students learn from and work with small business owners. As part of the MBAs Across America program's first year, four students drove 8,000 miles to provide entrepreneurs with free business counseling. The program has expanded, and this year, teams of MBAs will use the Volts to travel to 25 cities to offer their services. Learn more about the partnership between Chevrolet and MBAs Across America in the press release below. A professor from the University of Michigan has found fuel cycle analysis to be too flawed to be relied upon for measuring CO2 impacts of transportation fuels. Professor John DeCicco of the university's Energy Institute feels that the flaws in calculating the carbon footprint of liquid fuel production and combustion make such lifecycle analysis impractical. He suggests, instead, to focus to carbon capture. Since capturing CO2 directly from a vehicle is probably never going to happen, DiCicco believes the solution is to capture carbon from the atmosphere in sectors outside of transportation. Says DiCicco, "Research should be ramped up on options for increasing the rate at which CO2 is removed from the atmosphere and on programs to manage and utilize carbon fixed in the biosphere, which offers the best CO2 removal mechanism now at hand. Such strategies can complement measures that control the demand for liquid fuels by reducing travel activity, improving vehicle efficiency and shifting to non-carbon fuels."

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: Chevy Volt promos, Audi e-gas partnership

GM is offering promotions on the 2017 Chevrolet Volt. As dealers receive the first shipments of the new model year of the Volt, the automaker is giving customers in certain areas (California, Connecticut, Massachusetts, Maryland, Maine, New Hampshire, New Jersey, New York, Oregon, Rhode Island, and Vermont) $1,000 cash back on their purchase. GM Financial is also offering lease discounts for a limited time, and trade-ins may be eligible for even more money back. State and federal incentives could add up to make the new Volt quite the bargain for the right customer. Read more at Clean Technica. The UK's potential exit from the European Union could mean tighter emissions regulations, potentially even in the UK. While Britain has fought against the EU on stricter rules, the "Brexit" could leave officials in Brussels free to strengthen air quality laws. The UK, despite giving up its seat at the table, would still be beholden to some rules as a member of the European Economic Area free trade agreement. British voters vote on a referendum to leave the EU on June 23. Read more from Bloomberg Business. Daimler will refrain from investing in battery pack production with other automakers for the time being. Daimler CEO Dieter Zetsche cites an overabundance of battery production, saying, "Contrary to the expectation four or six years ago when everyone thought that the cells would be a rarity that could even be used as a tool of industrial policy, there is de facto a massive overcapacity in the market today and cells have become a commodity." Daimler recently shuttered its own lithium-ion battery production due to high costs and low demand. Read more from Automotive News. Audi is partnering with the Viessmann Group to increase e-gas production using a new biological process. Audi has been making the renewable fuel through a two-part process of electrolysis (splitting water into oxygen and hydrogen) and methanation (reacting hydrogen with CO2 to make synthetic methane). The new biological process uses microoganisms to absorb hydrogen and CO2 to make methane. The process requires lower temperature and pressure, and doesn't require high concentrations or purity of CO2. Read more in the press release below.
