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.

How does a 600-HP Audi RS6 Avant Plus sound to you?

The 2013 Audi RS6 Avant was announced back in December with a twin-turbo V8 cranking out 560 horsepower, but Car is reporting that this badass grocery getter could get even more power with a new Plus model. In a conversation with Car, Stephan Reil, Audi's top guy at its Quattro GmbH division, told the magazine that the RS6 Avant Plus would produce around 600 horsepower, and it sounds like there is a growing family of RS Plus models being planned as well.
Aside from the more powerful engine, the specifics of the RS6 Avant Plus are unknown, but we'd suspect some weight-savings measures and updated features for improved handling. Like recent RS Plus models such as the TT RS Plus and R8 Plus, the RS6 Avant Plus will not be a limited-production unit when it goes on sale (most likely for the 2014 model year).

Formula E is on track financially, with NYC race coming up

LONDON - Formula E could be breaking even already were it not investing for the future, chief executive Alejandro Agag said on Monday after the electric motor racing series reported continuing losses in its latest annual accounts. Accounts filed at Companies House showed Formula E Operations Ltd reduced its operating loss to 33.7 million euros ($38.32 million) at end-July 2016, a period covering its second season, from a previous 62.7 million. Net liabilities rose to 107.2 million euros from 72.1 million, while total revenues reached 56.6 million from a previous 19.7 million. "Everything is going according to plan," Agag, whose city-based series will be racing in New York for the first time on July 15 and 16, told Reuters in an interview at his London offices. "Actually we are doing incredibly well financially according to our plan. "We could have broken even this year but we decided to invest more in marketing and promotion. We decided to add races like the one in New York, which is in year one a race which is costing, we have significant capital expenditure." "It's really up to us when we want to go to break even or not. We could be in break-even now, we could be in break-even next season but we may decide to invest more in marketing and promotion." Agag said the shareholders, including John Malone's Liberty Global and Discovery Communications, were supportive of the strategy and the series had attracted more investors, sponsors and car manufacturers. The New York races will be held in Brooklyn's Red hook neighborhood, with lower Manhattan and the Statue of Liberty as a backdrop with technology partner Qualcomm securing the naming rights. MANUFACTURER INTEREST Agag, whose series plays down competition with Liberty Media-owned Formula One, said more carmakers were set to join a series increasingly aligned with their commercial focus. "I think Formula E has become the preferred destination for manufacturers and there are a few reasons for that," said the Spaniard. "Obviously, one is that it is electric and manufacturers are more and more focusing on electric cars...and we are the only platform really to help them promote that technology and those types of cars. "And second, because of the cost. The cost of the team in Formula E is very moderate." Whereas top Formula One teams can burn through $300 million a year, as can the likes of Toyota in the World Endurance Championship, the budgets of successful Formula E teams are between 10 and 15 million.
