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.

Automakers need to stop stalking celebrities

Since the invention of the automobile, cars and stars have gone together like paparazzi and the Kardashians. During this season of starlet-adorned award ceremonies, from the Golden Globes through to the Oscars, you will find a lot of car companies all vying to loan out their vehicles to any celebrity with a recognizable face who happens to be heading to a red-carpet award ceremony. There is, however, none so coordinated, consistent and aggressively playing the Fame Game as our friends at Audi. Since the invention of the automobile, cars and stars have gone together like paparazzi and the Kardashians, so by association getting a celeb behind the wheel of your car brand gives it an instant image boost that must make the car more attractive to buyers. Celebrity tales equals dealership sales. That's the logic, anyway. But surely the millions of dollars spent giving free cars to rich stars is a waste of precious and increasingly smaller marketing budgets. It's time to make the car the star, not the other way around. Lets be clear, we are not talking about the very obvious dropping of famous faces into big budget ads. That has its place in the marketing toolbox, but in a very media savvy world it's clear most of us get that play-for-pay concept. Today, the use of just a famous name in an ad yields very little influence on whether you or I will buy that car. No, this awards-ceremony loaner deal is a subtler, but higher risk, idea that if you see a "star" with "their" car in "real life" then surely that adds to the car's appeal. We, the audience, are expected to start salivating like Pavlovian puppies in our desire to have same car in our own, less red-carpeted driveway. Geoff Day has been called the "Pied Piper" of the auto industry, leading auto journalists on wild rides around the globe in his position as former director of communications for Mercedes-Benz USA. Before that, he worked at DaimlerChrysler UK on its PR efforts, and rubbed elbows with the Queen of England in his role at the Buckingham Palace Press Office. His phone is filled with the numbers of the great, the good and the bad. His head is filled with dirty little secrets hiding in many corners of the auto industry. There is no doubt that the publicity that comes with a well placed story, picture or feature can help raise awareness of a product – Oprah proved that with her "Favorite things" – especially if you are launching a line of wrinkle cream or juice bars.
