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 and Hyundai team up to boost hydrogen fuel cell cars

Hyundai agreed a deal with Audi on Wednesday to collaborate on hydrogen car technology, hoping to boost an energy segment that has lagged behind battery electric vehicles. The South Korean firm wants to increase the sales and acceptance of hydrogen cars, which are propelled by electricity generated by fuel cells but have been held back by a lack of infrastructure and the push for battery electric vehicles by the likes of Tesla. The pair will be able to access each other's intellectual property and share components, including any new parts developed by Audi, which is responsible for hydrogen fuel cell technology in the Volkswagen Group, the world's biggest car seller. Hyundai hopes that the move will create greater demand for vehicles such as its ix35 model and bring down costs to make the technology profitable. "We want to provide to our component suppliers more chance and we want to have competition between component suppliers," Sae Hoon Kim, the head of Hyundai's R&D fuel cell group, told Reuters in an interview in London. "We also want to make them to have competition with other suppliers, and that competition will bring down the cost." Carmakers such as Toyota have touted the benefits of hydrogen vehicles, which take less time to refuel than the recharge times of battery electric cars, but are expensive and suffer from a lack of refuelling stations. Many carmakers are focusing on battery electric vehicles, which can take between half an hour and half a day to recharge, but are increasingly able to use a growing network of charging points. Auto firms are teaming up to share the cost of developing greener technologies to replace combustion engines as regulators around the world crack down on emissions. GM and Honda have a partnership to jointly develop electric vehicles with hydrogen fuel cells that are expected to go on sale in 2020, while BMW is working with Toyota. Kim said that a toughening of European Union carbon emission limits in 2025 would create a need for more hydrogen cars. Hyundai sold 200 such models last year and expects to sell thousands this year, but Kim said profitability was still far off. "100,000 or 300,000 vehicles per year per company, when that comes, I think we can make money," he said.

Audi Q8 E-Tron could have 370-mile range

Audi technical boss Ulrich Hackenberg has a huge job ahead of him if he's going to add more electrified models his employer's portfolio. Currently, the German company's electrified offerings amount to just the Q5 Hybrid in the US and the A3 E-Tron in Europe, but British auto mag Autocar is claiming that Hackenberg wants to add a Tesla Model X-rivaling electric version of the company's long-rumored Q8 utility vehicle to the plans. That E-Tron model, said to be a high-riding crossover with coupe-like lines, is expected to be Ingolstadt's CUV flagship, positioned just above the Q7 (pictured above).
Autocar further maintains that Q8 E-Tron will borrow its front- and rear-mounted electric motors (good for around 375 horsepower) from the recently revived R8 E-Tron, and the model could be ready as soon as 2017. This sporty CUV is expected to have a much greater range than the two-door electric sports car, however. Figure on about 370 miles thanks to room for extra batteries.
The still-not-confirmed Q8 range is expected to be offered with gasoline, diesel and plug-in hybrid powertrains, and will ride on the same platform as the Q7, albeit fitted with sleeker styling. Like all of Audi's upper-end offerings, it will make extensive use of aluminum for the body and chassis to keep weight down.
