Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

2015 Audi A6 spiffs up for Paris Motor Show duty

While the big names at the Audi booth might be dominated by the TT line, it's not the only product getting some attention from the German company. The A6, on sale in its present form since 2012, is getting its official mid-cycle refresh.
Featuring light exterior freshening, the new fascia wears a tweaked grille and slimmer, more expressive headlights. The rear end sees more substantial changes, with a freshened rear bumper that features rectangular exhaust outlets and more dramatically redone taillights.
Under hood, the 3.0-liter, supercharged V6 engine now produces 329 horsepower, while the 3.0-liter, turbodiesel V6s are available in 215- or 268-hp varieties, or in twin-turbocharged form, with 315 hp or 322 hp. The other big powertrain news surrounds the transmission. Audi has finally dropped the continuously variable transmission from the base, front-drive A6, slotting in a dual-clutch transmission in its place.

Recharge Wrap-up: Atieva making EV with former Tesla talent, Holland lowers PHEV incentives

A reduction of tax incentives on company cars in Holland is expected to put the brakes on plug-in hybrid sales. Cars are taxed at an average of 25 percent, with plug-in hybrids taxed at just seven or 14 percent, depending on emissions. Taxes on PHEV company cars will increase to 14 and 21 percent. With company car leases making up a third of vehicle sales in 2014, the uptake on PHEVs "will likely go back to regular volumes," according to Volvo's Christiaan Krouwel. It could be a boon for battery electric cars, as their tax rate will remain at four percent for company cars. Read more at Automotive News Europe. Ford is testing cylinder deactivation in its 1.0-liter EcoBoost engine. On-road prototype testing has shown improvements in fuel economy of as much as six percent. Ford engineers developed a system using a new dual mass flywheel, pendulum absorber, and tuned clutch disc to allow cylinder deactivation under a wider range of speed and engine loads with less NVH. "The highest priority in the development of new combustion engines for automotive applications is the ongoing reduction of fuel consumption," says Ford's Andreas Schamel, presenting Ford's findings to the Vienna Motor Symposium.

The Silicon Valley-based startup was founded in 2007 by a former Tesla vice president, and its roster includes 12 other former Tesla employees. Already well funded, Atieva is now looking to fill its ranks with more talent, with 32 engineering positions, two recruiter positions and other job openings posted at its website. As for the EV it is working on, Atieva says it is "redefining what a car can be, by building an iconic new vehicle from the ground up." Read more at Charged EVs. Testing shows that Joule ethanol, made from recycled CO2, meets standards for use in the US and Europe. In partnership with Audi, Joule has been working toward making its recycled CO2 fuels ready for commercialization. "We are pleased to achieve another critical step towards our planned near-term delivery of fuel-grade ethanol from recycled CO2," says Joule President and CEO Serge Tchuruk. "Using waste CO2 as a feedstock, our technology has the two-fold advantage of reducing greenhouse gas emissions and producing cost-competitive, drop-in fuels." Joule will use these test results to get government approval for the use of its ethanol in highway fuel.
