Audi TT offroad concept wirelessly charges E-Tron quattro powertrain

Audi has been diving deep into the concept ideas pool for a while now, with out-there auto-show-only vehicles like the off-road Nanuk Quattro Concept (last year's Frankfurt Show) and the TT-previewing Allroad Shooting Brake (Detroit earlier this year). The automaker has also been hinting at wireless charging through its work with WiTricitiry and the Urban Concept Sportback from Frankfurt 2011. The latest evolution of these ideas is the brand-new Audi TT offroad concept show car, which makes an appearance at the Beijing Motor Show this weekend after being teased earlier this month. Putting wireless charging into an off-road body makes little sense at first glance - after all, if you're heading out into the wild, you'll be lucky enough to find a standard outlet - finding an in-ground induction pad will be near-impossible. Thankfully, we don't need to worry ourselves with this sort of logical conflict, since this is once again an auto show study. The powertrain is capable of 408 hp and 479.2 lb-ft of torque as well 123 MPGe. And that means interesting powertrain details, like a plug-in hybrid E-Tron quattro powertrain that uses two electric motors (one rated at 40 kW for the front axle, the other at 85 kW for the rear) and can even dispense with the plug part thanks to Audi Wireless Charging technology. The powertrain is capable of a total system output of 408 horsepower and 479.2 pound-feet of torque as well as a provisional fuel efficiency of over 123 miles per gallon equivalent. All with the ability to hit 100 kilometers per hour (62 miles per hour) in 5.2 seconds and a top speed of 155 mph. All-electric range is pegged at 31 miles thanks to a 12-kWH lithium-ion battery. More details than you can shake a stick at are available below. Audi says the TT offroad concept, which blends both coupe and compact SUV, could be a preview of "a new model in a future TT family," so if you've been hoping for another entry in the growing crossover coupe segment, tell Audi you'd like to see this in the real world some day.

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.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.
