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 builds its six-millionth Quattro-equipped car

All-wheel drive has become the norm particularly among German automakers. Mercedes offers its 4Matic system on a broad range of models, BMW counters with its xDrive system, Volkswagen has 4Motion, and the only Porsche you actually can't get with all-wheel traction is the Boxster/Cayman. But before all its competitors got on board with channeling power to all four wheels, Audi was making a name for itself with its Quattro all-wheel-drive system.
Now 34 years since the advent of the original Audi Quattro, the House of the Four Rings has built its six millionth vehicle equipped with all-wheel drive - only a year and a half since it hit the five-million mark. In fact these days nearly half of all new Audis are ordered in Quattro spec - more than any other automaker - resulting in a total of 710,095 Quattro-equipped Audis produced last year alone.
The landmark 6,000,000th vehicle was an SQ5 in monsoon gray metallic that rolled off the assembly line on Friday and is bound for a customer right here in the United States.

Audi Q3 production begins in Spain

It wasn't that long ago that Audi had no SUVs in its lineup - aside from the A6 Allroad Quattro - despite being known for its all-wheel-drive vehicles. But that's all changed, just as it has for BMW and Porsche. The Q7 was followed by the Q5, and now the Q3 has started production as well.
The first Q3 rolled off the assembly line today at the plant in Martorell, Spain. The facility belongs principally to Audi's sister-company Seat, but has gone through a considerable expansion - funded by both Audi and Seat - to prepare for the Q3's production.
