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 rolls out new A6 L E-Tron hybrid for China

Audi is expanding its range of hybrid models with the introduction of the A6 L E-Tron at the Shanghai Motor Show. It's earmarked specifically for the Chinese market and is based on the long-wheelbase A6 L already produced there. The new E-Tron model marries a 2.0-liter turbo four good for 211 horsepower and 258 pound-feet of torque to an electric motor with 122 hp and 162 lb-ft integrated into the eight-speed automatic transmission. A lithium-ion battery pack provides 14.1 kWh power. Mounted in the trunk, it limits cargo capacity to 11.9 cubic feet. The system produces net output of 245 hp and 369 lb-ft – enough to send the long-wheelbase hybrid to 62 miles per hour in 8.4 seconds en route to a top speed of 130 mph. All the while, it'll return 106.9 miles per gallon by the Chinese standard, traveling over 30 miles on electric power alone (at speeds of up to 83.9 mph) and up to 546.8 miles without needing to stop. The A6 L E-Tron is one of three new hybrids Audi is showcasing in Shanghai this year, alongside the Q7 E-Tron and Prologue Allroad concept. Ingolstadt, 2015-04-16 The new Audi A6 L e-tron for China - First Audi plug-in hybrid model from Chinese production - Output of 180 kW (245 hp) with extremely low consumption - 50 km (31.1 mi) electric range and total range of 880 km (546.8 mi) With the A6 L e-tron, Audi is taking an important step toward even greater fuel efficiency in China. The sedan has been developed specifically for the Chinese market. Its plug-in hybrid drive with 180 kW (245 hp) provides for powerful performance. The model consumes on average just 2.2 liters of fuel per 100 kilometers (106.9 US mpg). After launching the e-tron era in China with the imported A3 Sportback e-tron* in 2015, Audi is taking the next step with the local production of the A6 L e-tron beginning in 2016. The model is based on the long version of the Audi A6, which is already built in China, and is configured as a highly efficient parallel hybrid, meaning that its two drives are arranged one directly behind the other. The 2.0 TFSI is a state-of-the-art, four-cylinder, gasoline engine producing 155 kW (211 hp) and 350 Nm (258.1 lb-ft) of torque. The disk-shaped electric motor provides 91 kW and 220 Nm (162.3 lb-ft) of torque. Together with a decoupler, this is integrated into the eight-speed tiptronic transmission, which transfers the power to the front wheels. System output is 180 kW (245 hp); maximum system torque is 500 Nm (368.8 lb-ft).

Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.
