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 R8 LMX has frickin' lasers for headlights

It might look like just another Audi R8, but Ingolstadt tells us this one is different: it is the limited edition Audi R8 LMX (click image above to enlarge) with laser-enhanced LED high-beam headlights. Audi introduced the laserlight technology on its R18 E-tron Quattro LMP1 race car and then promised a production version of it at this year's Consumer Electronics Show. The eyes on the R8 LMX employ the same method when traveling above 37.3 miles per hour, utilizing a tiny laser module in each headlight that, after conversion to white light, can throw a beam about 1,640 feet down the road.
Because no one should ever stop at lasers, buyers of the limited-to-99 examples of the R8 LMX will also get a more powerful engine, with 570 horsepower erupting from the mid-mounted V10; that's ten more horses than came with the R8 V10 GT introduced last year, but the 0-62 mile-per-hour time hasn't budged from 3.4 seconds. It comes in coupe form only, dressed in Ara Blue paint with carbon accents all around, exclusive wheels, red brake calipers, and a black Nappa leather interior with contrasting blue bits.
The order book is open now, and deliveries will begin this summer for those willing to lay down 210,000 euros for the privilege of using one of Superman's powers for good, as standard (the BMW i8 has laser-equipped high beams, but as an option). We won't see them here, though, for as with Matrix Beam lighting and Audi's sequential turn signals, US laws forbid such shenanigans. The press release below has more info.

Enjoying The Romance, Not Yet Convinced About A Commitment
I imagine spending time with a sexy sports coupe is similar to a first date with a supermodel. Before she arrives, there's a buildup of excitement mixed with nervous anticipation. Even though the background work is done, there are many concerns and unanswered questions about how the two of you will get along. What about compatibility, engagement and dynamics?
The big day arrives, and you answer the door to find her waiting in the driveway wearing a form-fitting Misano Red Pearl dress and sleek Anthracite stilettos. As you shake your head in disbelief, you swear she just winked her... ah... xenon headlight at you.
