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.

Audi A3 Clubsport Quattro concept bringing its 525 horses to W?rthersee

It's almost late May, and you know what that means: the last of the snow has melted, the Stanley Cup playoffs are in full swing, the flowers are blooming, and the performance-car faithful are descending on Wörthersee in Austria for the annual GTI-Treffen.
Not only is the Wörthersee Tour (as the automaker calls it) a chance for enthusiasts to show off their rides, it's also a prime opportunity for the Volkswagen Group to show some of its most dedicated customers what it can do. Past meets have given us such notables as the Audi A1 Clubsport Quattro, Volkswagen GTI W12-650 and Skoda Fabia RS 2000 Roadster, to name just a few. And now Audi has emerged as the first VW Group brand to reveal what it has in store.
It's called the A3 Clubsport Quattro, and seems to offer a pretty clear indication of what we should expect of the next RS3. The concept is based on the S3 sedan, but swaps out its 2.0-liter turbo four for a retuned version of Audi's sweet 2.5-liter turbocharged inline-five, retuned to produce a massive 525 horsepower and 442 pound-feet of torque.

Audi R8 LMX has frickin' lasers for headlights

It might look like just another Audi R8, but Ingolstadt tells us this one is different: it is the limited edition Audi R8 LMX (click image above to enlarge) with laser-enhanced LED high-beam headlights. Audi introduced the laserlight technology on its R18 E-tron Quattro LMP1 race car and then promised a production version of it at this year's Consumer Electronics Show. The eyes on the R8 LMX employ the same method when traveling above 37.3 miles per hour, utilizing a tiny laser module in each headlight that, after conversion to white light, can throw a beam about 1,640 feet down the road.
Because no one should ever stop at lasers, buyers of the limited-to-99 examples of the R8 LMX will also get a more powerful engine, with 570 horsepower erupting from the mid-mounted V10; that's ten more horses than came with the R8 V10 GT introduced last year, but the 0-62 mile-per-hour time hasn't budged from 3.4 seconds. It comes in coupe form only, dressed in Ara Blue paint with carbon accents all around, exclusive wheels, red brake calipers, and a black Nappa leather interior with contrasting blue bits.
The order book is open now, and deliveries will begin this summer for those willing to lay down 210,000 euros for the privilege of using one of Superman's powers for good, as standard (the BMW i8 has laser-equipped high beams, but as an option). We won't see them here, though, for as with Matrix Beam lighting and Audi's sequential turn signals, US laws forbid such shenanigans. The press release below has more info.
