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.

Audi highlights headlights on upcoming new R8

Audi is preparing to roll out an all-new R8... but it's not about to reveal the whole thing at once. So in the first in what promises to be a series of teasers, the German automaker is showing off the new supercar's headlights. (Or headlight, we should say, in the singular.) Not unlike the R8 LMX revealed in Paris, the second-generation Audi supercar will incorporate LED headlights with an optional laser high-beam module. Unfortunately since laser headlights are illegal in the United States, the option isn't likely to be offered here. That is, at least, until Audi succeeds in convincing federal regulators otherwise. Although the teaser image above, like the press release below, may shine the light (so to speak) principally on the headlights, the shrouded shape also gives us a (little) bit to chew on. Yes, it will be available in blue, but beyond that we can expect the new R8 to incorporate slightly more angular lines than the model it replaces, with a more pronounced trapezoidal grille up in an overall design similar to the new TT, only more so. But then we already knew that much and more from the undisguised image that leaked out a little over a week ago. Ingolstadt, 2015-02-16 Audi reveals laser headlights for the new R8 - New mid-engine sports car features high-tech headlights - Laser high-beam offers high light intensity and excellent range Audi is revealing the headlights of its new R8* as the first of a number of technology highlights of the top sports car. The R8 uses LED headlights which can be supplemented by a laser high beam lighting module as an option. The new R8 will set new standards among high-performance sports cars – including in its lighting technology. As an option, the latest car development by Audi can be equipped with a laser spot as the high-beam headlight. The special appeal of laser lighting is that it uses high-intensity laser diodes, which generate a lot of light energy from a very small component. Compared to LED high-beam headlights, laser high-beams attain nearly twice the lighting range. Each headlight contains one laser module that operates with four high-intensity laser diodes. This module bundles the four intense blue-light laser beams. Then a phosphor converter transforms the blue light into pure white light. An identifying characteristic of the laser headlights is their blue light signature. Standard equipment in the new R8 includes an LED headlight system.

Why BMWs are cheaper than Hyundais in Korea

Bloomberg reports shifting tariff regulations have upended the traditional automotive pecking order in Korea. Thanks to cheaper import taxes, foreign brands have seen market share jump from 28 percent to 41 percent over the last two years. BMW, Mercedes-Benz and Audi have all capitalized on the shift, with domestics like Hyundai and Kia suffering at the hands of their German rivals.
Taxes on European imports have fallen from 8 percent in 2011 to just 3.2 percent today. Over the next few years, tariffs will all but be eliminated for most imports, and taxes on US-made vehicles are expected to fall to just 4 percent in 2014. By 2016, that number will be zero. Needless to say, Hyundai and Kia are concerned about the shift.
Hyundai has seen profit fall by 15 percent last quarter, and the company says it is on pace to see the slowest sales growth since 2007. The company's shares have fallen by 12 percent. In order to stem the losses, Hyundai has discounted its midsize sedans and started working on diesel engine options.
