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.

2014 Audi A6, A7 and Q5 TDI diesel models get pricing and fuel economy figures [w/videos]

Last year, Audi announced that it was expanding its lineup of TDI models for 2014 with the Q5, A6 and A7 joining the diesel-burning Q7 and A8 L models already in existence. The Q7 TDI has been out for a few years now and we recently drove the A8 L TDI, but now Audi has released the pricing, performance and fuel economy details for the 2014 Q5 TDI, A6 TDI and the ever-stylish A7 TDI. Down the road, Audi has also promised a TDI version of the next-generation A3 that will debut for 2014.
Until the new A3 TDI shows up, the Q5 will be the most affordable diesel model in Audi's lineup, with a starting price of $46,500 to go with fuel economy estimates of 24 mpg city and 31 mpg highway. The closely related A6 and A7 will get identical fuel economy numbers of 24 city and 38 highway in diesel form, with the A6 TDI starting at $57,500 and the A7 TDI starting at $66,900. In the three new TDI applications, Audi's 3.0-liter V6 produces 240 horsepower and 428 pound-feet of torque, and all models are paired with an eight-speed automatic transmission. Scroll down for videos (stock running footage) and more information on the Q5 TDI, A6 TDI and A7 TDI, all of which go on sale in late summer.

Editors' Picks January 2022 | Ford Maverick, Jeep Grand Cherokee and more

This month, we awarded Editors' Pick awards to a number of totally redesigned, new models. Most notable of the bunch is the 2022 Ford Maverick. Ford took a chance on a new segment, and its execution is as close to perfect as we could hope for. The Hyundai Santa Cruz is a worthy competitor, though, and was also named an Editors' Pick. Also in this list, we have the redesigned Jeep Grand Cherokee. It's an excellent SUV, and it's only going to get better when the plug-in hybrid 4xe model hits the roads. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in January that earned an EditorsÂ’ Pick. 2022 Jeep Grand Cherokee Quick take: Jeep's midsize SUV hits it out of the park with the latest generation. We could stand to see some powertrain innovation, but the Grand Cherokee's premium proposition is sound. Score: 8.0 What it competes with: Honda Passport, Hyundai Santa Fe, Ford Edge, Chevrolet Blazer, Nissan Murano Pros: Highly capable, luxurious interior, choices aplenty Cons: Pricey, fuel economy From the editors Associate Editor, Byron Hurd — "Jeep did almost everything right with the redesigned Grand Cherokee. Its powertrain offerings are fairly unremarkable, but the new two-row 4xe will go a long way toward addressing that. It's an otherwise fantastic, modern, luxurious Jeep SUV." In-depth analysis: 2022 Jeep Grand Cherokee First Drive Review | 1 fewer row, 1 more touchscreen   2022 Ford Maverick Quick take: The Ford Maverick offers tremendous value, efficiency, incredibly well-thought-out packaging, plenty of storage, a fairly engaging drive and ease of use, all with the utility of a pickup bed. We like the hybrid, but the EcoBoost engine and FX4 package offer more capability. Score: 8 What it competes with: Hyundai Santa Cruz Pros: Very affordable, Hybrid fuel economy, compact size Cons: Tight backseat, FWD only Hybrid, no cruise control in base trim From the editors: Green, Senior Editor John Beltz Snyder — "The Maverick is simply a dynamite package. It's smart, useful, drivable, efficient, providing affordable utility in the underserved compact pickup segment.
