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 Q7 spotted with a blurry first look

Here's the good news: we finally have visual evidence of the upcoming and all-new 2015 Audi Q7 luxury SUV. A set of photographs show that Audi has been putting the SUV through its paces, with an eye towards an on-sale date sometime late next year.
The bad news is that it was not one of our usual clear-lensed spy photographers that captured these first images, but rather a sycophantic follower of our friends at CarPix. The resulting images are a lot lower resolution than we've come to expect, and there are far fewer angles from which to judge the car.
Still, we can make out the nose of the new Q7 is a bit flatter and wider than the rounded affair of the current car, and wears similar swoopy LED headlights as are found in the rest of the Audi range. We expect the overall dimensions of the 2015 Q7 to stay about the same as the existing model, but rumor has it that the SUV could be 800 to 900 pounds lighter in the next generation.

Dysfunctional dashboards: Auto suppliers competing to clean up the cockpit

SAN FRANCISCO - Peer at the instrument panel on your new car and you see sleek digital gauges and multicolored screens. But behind the dashboard, here's what US auto supplier Visteon Corp found: a mess. As automotive cockpits become crammed with ever more digital features such as navigation and entertainment systems, the electronics holding it all together have become a rat's nest of components made by different parts makers. Now the race is on to clean up the clutter. Visteon is among a slew of suppliers aiming to make dashboard innards simpler, cheaper and lighter as the industry accelerates toward a so-called virtual cockpit - an all-digital dashboard that will help usher in the era of self-driving cars. What's at stake is a piece of the $37 billion cockpit electronics market, estimated by research firm IHS Market to nearly double to $62 billion by 2022. Accounting firm PwC estimates that electronics could account for up to 20 percent of a car's value in the next two years, up from 13 percent in 2015. Meanwhile, the number of suppliers for those components is likely to dwindle as automakers look to work with fewer companies capable of doing more, according to Mark Boyadjis, principal automotive analyst at IHS Markit. "The complexity of engineering 10 different systems from 10 different suppliers is no longer something an automaker wants to do," Boyadjis said. He estimates manufacturers eventually will work with two to three cockpit suppliers for each model, down from six to 10 today. DIGITAL MAKEOVER One of Visteon's solutions is a computer module dubbed "SmartCore." This cockpit domain controller operates a vehicle's instrument cluster, infotainment system and other features, all on the same tiny piece of silicon. So far this year, the Detroit-based company has landed two big contracts for undisclosed sums. One, announced in April, is with China's second-largest automaker, Dongfeng Motor Corp. The other is with Mercedes-Benz, Reuters has learned. Mercedes did not respond to requests for comment. Another unnamed European automaker plans to use the system in 2018, according to Visteon. Visteon is going all-in on cockpit electronics, having shed its remaining automotive climate and interiors businesses in 2016. The bet so far is paying off. The company secured $1.5 billion in new business in the first quarter, helped by growth in China. Visteon's stock price is up more than 50 percent over the past year.
