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.

VW has received several tentative bids for Ducati

Italy's Benetton family is vying with motorbike firms and buyout funds for control of Italian motorcycle brand Ducati, which is being sold by Germany's Volkswagen, sources involved in the process told Reuters. Volkswagen, whose Audi division controls Ducati, has received several tentative bids with the Benetton family's investment vehicle Edizione Holding valuing the Monster motorbike maker at $1.2 billion, one of the sources said. As well as Edizione Holding, U.S. buyout fund Bain Capital, which owns a stake in Ski-Doo snowmobiles maker BRB, and two Indian motorbike firms, Eicher Motors and Bajaj Auto, have also bid for Ducati, the sources said. Indian carmaker Eicher controls Royal Enfield, a motorcycle brand established in 1893 which ranks as one of the oldest. Strategic bidders also include U.S. automotive firm Polaris Industries, which earlier this year said it would wind down its struggling Victory Motorcycle brand. A shortlist of bidders for a second stage of the auction could be selected as soon as Saturday, two of the sources said. Volkswagen adviser Evercore has a long list of bidders including private equity funds such as Ducati's previous owner Investindustrial, CVC Capital Partners, Advent and PAI, all hoping to outbid industry players, the sources said. If it gets to the second round, Edizione Holding could seek to form a consortium with a financial investor, two of the sources said, in a bid to secure control of Ducati, whose racers have won the Superbike world championship 14 times, with Carl Fogarty and Troy Bayliss its most successful riders. Audi, Edizione Holding, Investindustrial, Advent and PAI declined to comment, while the other interested groups were not immediately available for comment. PRICING CHALLENGES For some buyout funds, Ducati's valuation of up to $1.4 billion – which sources said is based on a multiple of more than 10 times its core earnings of roughly 100 million euros – is a tall order as they lack the synergies that some motorbike makers could achieve. But Investindustrial founder Andrea Bonomi, who sold Ducati to Audi for about 860 million euros in 2012, is serious about a comeback, one of the sources said. China's Loncin Motor was among a group of industry players that initially showed interest in Ducati, alongside Harley-Davidson. The latter has, however, decided against making a bid due to Ducati's price tag, while it could not be established if Loncin Motor had carried on bidding.

Audi unveils its Doberhuahua Super Bowl commercial

With Super Bowl Sunday less than a week away, this week is going to be dominated by anything and everything football related. That includes advertising and the auto industry, as some of the biggest players prepare to launch multi-million-dollar spots hawking their latest and greatest products.
A veteran of Super Bowl ads, Audi's history has been rather checkered, ranging from controversial to funny to Jason Statham. We aren't entirely sure where to place this year's ad. The German brand has released a pair of teaser videos on the so-called Doberhuahua, a crossbreed of a Doberman Pinscher and a Chihuahua. Now, we have the full spot.
We get the message Audi is going for - compromise is bad - but delivering it via a slobbery, mutant dog strikes us as trying a bit too hard to be funny. Take a look below and let us know what you think of the Audi's Doberhuahua spot. And of course, you'll be able to see the new ad come Sunday, when it airs during the Super Bowl.
