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.

Autoblog's ultimate holiday rides

Over the hills and through the woods, it's the time of year when many of us visit family and friends for the holidays. But getting there can be a chore. It's cold and snowy across much of the United States, and even if the climate is favorable, the drive to grandmother's house often is not. Think back to holiday road trips of yore: They probably included crying babies, antsy children, hungover adults and frequent bathrooms stops all around. Now, we're all at different life stages here at Autoblog, and the perfect car for one staffer might be as useful as a team of Budweiser Clydesdales to another. Some of us bounce from family event to family event with children and a labrador in tow, while others prefer a quieter, simpler holiday. But whatever the endeavor, we all need wheels. With that in mind, here is the unofficial Autoblog list of the ultimate cars in which to tackle the holiday season. 2015 Ferrari FF To borrow a chestnut from Top Gear presenter James May, "As you'd expect, I've done this properly." That oddly voluptuous ruby bolide in the photo above? It's a 2015 Ferrari FF – all 652 all-wheel-driven horsepower of it. What makes a Ferrari the ideal for holiday time in PaukertLand? My Midwestern winter breaks are wonderful, but they're typically frenetic and slushy, involving a lot of schlepping from house to house and even city to city, not to mention inevitable last-minute runs for forgotten presents and dinner ingredients. Needless to say, a powerful V12 is a welcome ally for such duties. And this one isn't just a friend when the road is clear. The FF has been gifted Ferrari's novel 4RM AWD system, and despite sitting lower to the ground than, say, an SUV, it's a pretty effective tool for real winter driving, especially when outfitted with a set of snow tires. Unlike other Ferraris, it's also a rather practical thing, with legitimate seating for four adults and 15.9 cubic feet of cargo space – that's precisely as much room as a Mercedes E-Class – and you can fold the rear chairs and cram 28.2 cubes-worth of holiday cheer in the back. Okay, so it's far from cheap and fuel economy isn't that great, but who cares? Just drop a paddle-shifted gear or two, bury the throttle and Repeat The Sounding Joy. Ain't the holidays grand? – Chris Paukert Executive Editor 2015 Chevrolet Tahoe My Mom gives out more presents than any other human being I've ever encountered.

Audi A5 DTM diesel sport coupe thumbs nose at scandal

While the diesel emissions scandal is damaging the reputation of the four-cylinder TDI engines, the torquey, fuel-efficient 3.0-liter TDI V6 at the heart of this latest special edition from Audi is so far unsullied. However that doesn't mean the 3.0 couldn't face investigation at some point in the future before the issue is settled. In the meantime, those outside of North America can look forward to the Audi A5 DTM edition's enticing features. The A5 DTM edition is powered by the same 3.0-liter V6 TDI that we can already get in the A6, A7, and A8 sedans as well as the Q5 and Q7 crossovers. Here, it produces 245 horsepower and 427 pound-feet of torque (in the US-spec A6, the engine is quoted as making 240 hp and 428 lb-ft). The A5 DTM channels its power to all four wheels through a seven-speed dual-clutch transmission. That's enough to propel it to 62 in a claimed 5.9 seconds and an electronically-governed top speed of 155 miles per hour. The sporty look is inspired by Ingolstadt's DTM touring car program. That includes a sportier front fascia, Misano red paint, gloss-black trim, 20-inch split-five-spoke alloys, and special badges inside and out. The interior packs the bucket seats from the RS5, Alcantara trim, stainless steel pedals, and more. Audi will only offer 50 examples, priced in Germany at ˆ74,540 – equivalent to about $85k at current exchange rates. Racing spirit – The Audi A5 DTM selection limited-edition model - Limited run going into production from October - 20-inch wheels, bucket seats and Misano red finish - Third DTM special edition from Audi Audi is taking the spirit of the DTM from the racetrack to the road – with the Audi A5 DTM selection* special edition. A powerful 3.0 TDI developing 180 kW (245 hp), 20-inch wheels, dynamic design and bucket seats reveal the two-door coupe's connections with the race version that has featured in the German Touring Car Masters (DTM). The Audi A5 DTM selection turns heads with its special racing design. The front lid, doors and rear window are emblazoned with dynamically designed DTM, quattro and Audi Sport logos. The Misano red paint finish contrasts with high-gloss black add-on parts on the front, sills and rear, giving added emphasis to the sports appeal of this limited-edition model. The front apron and the large air inlets with their rhombus-pattern grilles also contribute to its special looks. The cast aluminum wheels by Audi Sport embrace a five twin-spoke design in matt titanium look.
