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.

Upcoming Audi Q1 rumored to get high-performance SQ1 variant

The Audi Q1 isn't due for another two or three years, yet Auto Bild reports already that it will come in RS and SQ1 trims. According to the report, the RS Q1 will be powered by a 2.0-liter four-cylinder putting out 300 horsepower and 280 pound-feet of torque, putting it about 70 hp and 8 lb-ft beyond the next-most-powerful gasoline engine in the standard range.
Depending on how you like your gumption served, however, the first SQ1 - like its European SQ5 sibling - go the diesel route with a 2.0-liter TDI fitted with twin turbos for 231 hp and 368 pound-feet of torque. That's an improvement of 47 hp and 88 lb-ft over the most powerful diesel engine said to be offered on the regular Q1.
The report goes on to say that there should be g-tron (natural gas) and e-tron versions of the Q1, and buyers will get a deep toy chest of assistance packages to equip it with. Starting price in Europe is expected to be around 25,000 euros, which, if correct, would make it 4,000 euros less dear than the Q3 in Germany.

First impressions of Audi's next TT interior and Virtual Cockpit [w/video]

Not content to pummel CES show goers with laser lights and self-piloting vehicles, Audi has also pulled the wraps (well, some of the wraps) off the interior of its upcoming next-gen TT. While the car itself wasn't on hand for us to check out, Audi did mock up the cockpit, complete with its all-new Virtual Cockpit central display and the latest iteration of the company's Multi Media Interface (MMI).
Virtual Display is Audi's new brand name for a completely digital reinterpretation of the instrument binnacle, by way of a 12.3-inch TFT screen. Audi tells us that there are two operable modes for Virtual Display: in the standard mode, an average-sized tachometer and speedometer flank a smaller infotainment portion in the center. Infotainment mode, meanwhile, shrinks the gauges to discreet circles and allows the navigation map, audio controls, or whichever system is being operated by the driver, to fill the remaining screen real estate.
This design, says Audi, allowed engineers to slim down the size of the center console as a whole, without reducing function for the driver. We can say that it looks very impressive as a demonstrator, but we will need some time with it in a moving vehicle before we're convinced it isn't slightly more distracting that a traditional setup.
