2014 Audi RS7 is a 189-mph terror

If you have a burning desire to take yourself and four friends to 189 miles per hour, the 2014 Audi RS7 Sportback can help you out. The luxury hatchback bowed at the 2013 Detroit Auto Show today, complete with a 560-horsepower twin-turbocharged 4.0-liter V8 engine thrashing under the hood. Getting to 62 mph takes a shave under 3.9 seconds thanks in part to the 553 pound-feet of torque on hand from just 1,750 rpm. While the base car comes with an electronically limited top speed of 155 mph, customers can request the governor be removed by purchasing the dynamic package plus, upping the V-max to 189 mph.
Ludicrous? Sure, but Audi says the RS7 can also yield up to 25 mpg on the US scale. With a cylinder-on-demand system, the V8 can deactivate up to four cylinders by closing their valves. Once the driver gets frisky with the throttle, the engine automatically kicks from four-cylinder to eight-cylinder mode in a few hundredths of a second. The engine is bolted to an eight-speed automatic transmission, which pushes power to all four wheels. You can read the full press release below for more information, but we think you'll have a better time viewing our live shots from the show floor..

2015 Audi A3 E-Tron [w/video]

Over the years, we've had a chance to test a lot of Audi E-Tron vehicles, from very early all-electric prototypes (back then we only got to sit in the passenger seat) to the A6 L E-Tron PHEV and the A1 E-Tron plug-in hybrid. All of them were concepts and promises, merely whispers of what was possible, even as the Nissan Leaf, Chevrolet Volt and two Tesla models were making waves in the marketplace.
As we learned last year in our Deep Dive of the E-Tron project, all of the concepts, prototypes and rumors have finally come to fruition in this A3 Sportback E-Tron. Previously, we were given a chance to drive a prototype, but it was only very briefly. Last week, we finally got to run a production-representative example through the hilly roads between Vienna, Austria and Munich, Germany. After spending a solid day with Audi's first marketable E-Tron vehicle, we can say that it's a most amazing bit of engineering, in particular for the way that Audi has done so much to hide the fact that this is an electrified vehicle. Not entirely, of course, but the idea was to make the A3 Sportback E-Tron a no-compromise PHEV. And that means it drives and feels, in many ways, like the standard A3 Sportback despite over 700 extra pounds. Oh, and there's a charge port hidden behind the four rings in the grille.

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.
