TT Offroad Concept shows Audi's design icon isn't afraid to play dirty

We'll step right out and say we like the TT Offroad Concept, but there's something that's just a bit too... familiar about it. Yes, this yellow five-door looks like a not-so-distant relative of the Allroad Shooting Brake Concept that debuted at the 2014 Detroit Auto Show earlier this year. So, we've seen the production TT, a super-light, high-performance model and now we're seeing a crossover. Does any of this sound familiar? Considering the Detroit concept earned an editors' choice award for that show, you can imagine how we feel about the strikingly similar TT Offroad, which is debuting at the Beijing Motor Show.
The two concepts share a propulsion system - a high-performance version of Audi's E-Tron plug-in-hybrid drivetrain. Total system output sits at 408 horsepower, thanks to a 2.0-liter, turbocharged four-cylinder and a 40-kilowatt electric motor in front and an 85-kW motor on the rear axle, for all-wheel drive. 62 miles per hour arrives in 5.2 seconds, while the TT Offroad is limited to 155 mph. Fuel economy is impressive, with a claimed 123.8 US miles per gallon on the European cycle.
The most obvious different between these two, then, are their looks. The TT looks a bit tougher, thanks to its larger 21-inch wheels and narrower headlights, but its more conventional belt and roofline give it more of an Audi Q3's look. Out back, a slightly restyled bumper is the sole differentiator between the two vehicles.

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.

Audi Nanuk Quattro Concept is a wild surprise ahead of Frankfurt

Volkswagen Group Night ahead of the Frankfurt Motor Show always has some surprises, the first of which this year is the Audi Nanuk Quattro Concept. The all-wheel-drive, turbo-diesel-powered supercar is similar to the Giugiaro Parcour Concept that was unveiled earlier this summer. In fact, the Parcour's creator, Italdesign Giugiaro, penned the Nanuk, and we suspect much of the former found its way into the latter - with some changes, of course.
The diesel engine, a departure from the Parcour, is a twin-turbocharged 5.0-liter V10 TDI unit that develops 544 horsepower and a hole-digging 738 pound-feet of torque, which make the 4,189-pound all-road vehicle able to dispatch 0-62 miles per hour in 3.8 seconds and go on to a 190-mph top speed. Fuel consumption is a relatively low 30 miles per gallon for a car with this much performance.
The Nanuk showcases Audi's Quattro, though it uses a specially designed version of the all-wheel-drive system to get the job done. Audi's next generation of adaptive air suspension is featured as well, which fits the crossover nature of the Nanuk. Drivers are given a range of 2.76 inches of height adjustment, though Audi doesn't mention the car's minimum or maximum ground clearance.
