VW may make Bentley a subsidiary of Audi

FRANKFURT — Volkswagen plans to make British luxury carmaker Bentley a subsidiary of its Audi division as it seeks economies of scale among its top-end brands, German trade publication Automobilwoche reported. Bentley, for now overseen by the head of VW's Porsche business, Oliver Blume, will from next year be part of Audi, where VW group Chief Executive Herbert Diess believes it has more potential, Automobilwoche cited company sources as saying. Synergies could include using Audi technology for a new Bentley SUV, it added. Volkswagen, which declined to comment on the report, is reviewing the future of its high-performance brands Lamborghini, Bugatti and Ducati motorcycles as part of broader quest for more economies of scale as it shifts to mass producing electric cars. Sources familiar with the matter told Reuters this month that Volkswagen was working on plans to prepare Lamborghini for a stock market listing. Related Video: Audi Bentley Volkswagen

Audi teases Frankfurt reveal... is it the A8?

Audi has already rumored to have plans to reveal a 650-horsepower Sport Quattro Concept at the 2013 Frankfurt Motor Show in September, but it also seems that we'll be getting our first look at the 2015 Audi A8 as well. Based on a panned-out shot of a teaser video, we can clearly see that this is a new sedan model, so it makes sense that is the updated A8 since we've already seen recent spy shots of that car that seemed to be almost complete.
In the short video, all that we can definitely see is the Audi logo in the grille, a five-spoke wheel with cross-drilled, ceramic disc brakes and a small portion of the front fender that has an almost mirror-like shine. We'll find out for sure in September, but until then, check out the teaser video posted below.

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.
