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.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.
