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.

Refreshed Audi A6 gets ready for Paris debut

The Audi A6 remains a solidly luxurious choice in the deeply competitive executive sedan segment, duking it out with the Mercedes-Benz E-Class, BMW 5 Series and Lexus GS, among others. Having been on sale since 2011, though, it's starting to become just a tiny bit stale. Cue the refresh.
Expected to make its debut in October at the 2014 Paris Motor Show, the long-roof Avant/Allroad variant shown here gives us our first glimpse at some of the tweaks Audi has in store for its A6 range as a whole.
In general, this is pretty standard refresh stuff - new headlights that retain the same general shape as the current car but add a new DRL pattern, while there are also some subtle tweaks to the front fascia. The rear taillights have also been freshened (although as only the A6 sedan is sold in the US, it's likely the taillights we see will be different), and some minor changes have been made to the rear bumper. According to our spies, the cabin and MMI infotainment system could see some tweaks, while the oily bits under the hood could be in for for some minor changes as well.

2016 Audi TTS

We recently drove the Audi TT, and although we wish it were radically entertaining instead of merely very fun, it's nevertheless a sharp coupe that vaults ahead of its predecessor with an inspired interior and eager handling. That car will be precursor to this TTS when it gets here a year from now, with the TTS adding adjectives like "more" and "better" to just about everything found on the base coupe. With the standard car having already put on such a fine edge, we wheeled the TTS on Spanish roads and at the Ascari race track to find out how much better and higher-performing the S will be.
Driving Notes
As of this writing, today's TTS commands an $8,350 premium over the TT. Assuming a commensurate gap is carried over into this next generation model, that supplemental dosh will get you 310 horsepower and 280 pound-feet of torque instead of 230 hp and 273 lb-ft in the standard TT. That would mean more for your money, too, since the gap between the current TT and TTS is 54 hp and zero lb-ft of torque. To achieve the new numbers, the 2.0 TSFI engine from the TTS benefits from upgrades like sturdier valves, revised aluminum pistons and stronger connecting rods with new bearings, a reinforced crankshaft and a high-performance intercooler. The amplified brawn rips 0.7 seconds off the 0-60 mile-per-hour time, getting you there in 4.6 seconds.
