Audi Sport Quattro Concept speaks softly, carries a 700-hp stick

As promised, Audi has unveiled its Sport Quattro Concept here at the Frankfurt Motor Show, which takes inspiration from the 2010 Paris Motor Show debut known simply as the Quattro Concept. Both cars clearly seek to draw upon the company's legendary 1980 Ur-Quattro and its closely related Sport Quattro short-wheelbase rally special, yet this concept car looks more production-minded than the 2010 starlet.
Despite its more conservative duds, this handsome and muscular coupe actually packs significantly more power than the 2010 Paris showcar. In fact, it musters 700 horsepower and 590 pound-feet of torque from its plug-in hybrid powertrain, versus the Quattro Concept's more historically appropriate 2.5-liter five-cylinder turbo with 408 hp and 354 lb-ft. We're not going to complain about a twin-turbo 4.0-liter V8 plus an electric motor, nor will we grouse about its 3.7-second 0-62 mph dash, 190-mph top speed or 2.5 liters of fuel per 100 kilometers on the Euro cycle (roughly 94 miles per gallon US).
Stubborn rumors abound that Audi will offer a limited-edition version of this four-place coupe for sale, but for now, the company isn't talking. If such a model is offered, it's expected to cost significantly more than the R8 supercar, which might be a tough sell considering that vehicle's similar performance and more voluptuous - if less practical - shape.

2016 Audi TT [w/video]

What came first, the metrosexual or the Audi TT? While it was close, the descriptor-turned-epithet preceded the 1995 concept car by one year. However, they were both notable cultural evolutions and they happened to work together perfectly. Hugh Grant, playing the cad Will Freeman in the 2002 film About a Boy, could not have chosen a better example of character than his silver TT.
A decade later, the original TT was still important enough that when rumors of the third-generation coupe began to surface in late 2012, the most exciting fantasy was that the 2014 coupe might "recapture some of the distinctiveness and impact" of a 16-year-old car (the TT came to market in 1998). Even speculation by dedicated Audi observers thought the brand would do something novel, even if not mimicry. The obvious takeaway: no one was going to be lighting any candles for the departed second generation. All of that is why when the first leaked image slipped onto the Internet, people began to get suspicious. When the third generation took the stage at the Geneva Motor Show, we could almost hear the digital deflation over the Ethernet, our poll results notwithstanding.
Yet it's still the TT, and in spite of having seen its interior and virtual cockpit and clocked its specs, we couldn't judge it before heading to Marbella, Spain to drive it. What we found out was while it's better than the second generation, it's still very much a TT.

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.
