Audi Prologue concept drives itself to CES with updated powertrain

What's the point in crafting a one-off concept car if it only gets to stand in the spotlight at one show? That's what automakers have been asking themselves recently, and the answer has, generally speaking, been to repaint their show cars, give them a bit of new tech and put them back on center stage. And the latest to do so is Audi, which has given its Prologue concept a new lease on life. The Prologue was originally unveiled at the Los Angeles Auto Show less than two months ago, showing the way forward for the future of Audi design, in an elegant coupe form that looked ready to take on the Mercedes S-Class Coupe. We even got a chance to drive it around the streets of LA, and when we did, we marveled at the concept's advanced infotainment system that caters a range of personal preferences according to who's on board. "It's easy to see how this could even reach for chauffeured, or autonomously driven vehicles" in the future, we said at the time. And it turns out Audi was on the same page. At CES this year, Audi has brought back the Prologue concept, given it a darker coat of grey paint, a grey-tone interior (instead of the previous shades of brown and tan), a fresh set of wheels and equipped it with the autonomous tech the German automaker has been at the forefront of developing. Though other automakers have been fitting their self-driving prototypes with all-electric powertrains, Audi kept the 4.0-liter twin-turbo V8 in place – but fitted it with a hybrid assist to drive output up from an already prodigious 605 horsepower and 516 pound-feet of torque to an even more impressive 677 hp and 701 lb-ft, dropping the 0-62 time down to 3.5 seconds. Now that's the kind of "piloted driving" tech (as Audi calls it) that we can get behind.

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.

South Korea to file criminal charges against VW exec

South Korea has tossed out Volkswagen's recall plans and is preparing to level criminal charges over its handling of the diesel emissions catastrophe, The Wall Street Journal reports. "Recall plans the company submitted to us earlier this month were insufficient and lacked key information, and thus are unacceptable," the South Korean Ministry of Environment said in a statement obtained by the WSJ. A ministry official hinted at the possibility of criminal charges earlier this month if VW's recall plan wasn't satisfactory, the Yonhap News Agency reports, and now it looks like it will actually follow through. According to the WSJ, South Korea has already ordered VW to recall 125,000 vehicles and slapped the automaker with a $12.3 million fine – one of the many countries to do so – but if it follows through with criminal charges against the company or its employees, it'd be among the earliest to so. Other countries, including the United States, are still exploring the possibility of criminal charges. Charges would likely come against both Audi Volkswagen Korea and its managing director, Johannes Thammer. It's not clear what the actual charge would be, but the WSJ claims Thammer could be facing up to five years in prison and a fine of 30 million won (around $24,700 at today's rates). For its part, VW officials in South Korea maintains that it is "doing its utmost to resolve the emissions issue" and that it plans to "offer further explanation" to authorities regarding its proposal for an emissions and fuel mileage fix in that country.
