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 S1 officially shows itself as 228-hp hot hatch [w/video]

We got the first leaked pics of the new Audi S1 Sportback five-door hot hatch yesterday, and as expected, Audi has unloaded the full details today, including confirmation of its S1 three-door sibling ahead of its debut at next month's Geneva Motor Show. The two cars are essentially identical aside from their door counts, and together, they represent a new entry-level rung into Audi's S car range.
The subcompact S1 is propelled by Audi's ubiquitous 2.0 TFSI four-cylinder, tuned here to produce 228 horsepower and 279 pound-feet with a six-speed manual transmission and all-wheel drive. The potent combo accelerates the S1 to 62 miles per hour in 5.8 seconds (5.9 seconds for the Sportback) and on to a top speed of 155 mph. Fuel economy is rated at an average 33.6 miles per gallon (40.3 mpg UK) in the UK cycle. The S also gets a completely different four-link independent suspension to replace the less sophisticated torsion beam setup found in the standard A1.
Styling also gets a bump in aggressiveness that befit the S1's performance upgrades. In addition to a new body kit with a lower front air dam and 17-inch wheels, the S1 comes standard with Xenon headlights, LED taillights and two new available exterior colors ­- Vegas Yellow and Sepang Blue. The interior gets combination leather and cloth sport seats, piano black trim and a retractable 6.5-inch color infotainment display.

2014 Audi A4 next car to go on big diet while adding features

The Audi A4 is expected to receive a major redesign over the next couple of years, and with the smaller A3 now gaining a sedan model, it is being reported that the A4 might be getting a little breathing room for a more advanced design and improved technology and features. According to AutoBild, this would include a drop of more than 200 pounds in curb weight, updated cabin tech and a wider variety of drivetrain options.
AutoBild states that Audi is looking to upgrade just about every detail - inside and out - when it comes to the 2014 Audi A4, and this includes a next-generation MMI system that uses two digital displays. Extensive use of magnesium, aluminum and plastics will help shave an estimated 220 pounds from the A4's curb weight, and in terms of engines, it sounds like the usual array of forced-induction, small-displacement gas and diesel engines will be on tap, but a bigger V6 TDI and a plug-in hybrid powertrain are also mentioned.
