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.

Volkswagen Group names Paefgen head of classics program

You may remember the name Franz-Josef Paefgen. Until recently, the German engineer and executive was head of both Bentley and Bugatti. Before that he was chief executive of Audi, after working for several years at Ford. He technically "retired" earlier this year, but like the cars he helped create, an executive like Paefgen could never really retire. So it should come as little surprise that the Volkswagen Group has named Dr. Paefgen head of its Classic program.
In his new capacity, Paefgen will oversee the historic automobile activities of the entire VW Group, including those of Volkswagen, Seat, Skoda, Audi, Lamborghini, and of course Bentley and Bugatti. It strikes us as a suitable semi-retirement for the man responsible in no small part for the Bugatti Veyron and Bentley Mulsanne, to name just two, and who was decorated in 2006 by the ACO as the "Spirit of Le Mans" for his contribution to endurance racing.

Audi A3 E-Tron launching at $51,500 in Germany

Audi has put a price tag on the A3 Sportback E-Tron plug-in hybrid, for which presales begin this month in Germany. To get your hands on one of these little guys, Audi is asking for ˆ37,900, or about $51,537 according to current exchange rates. Of course, the base MSRP doesn't include any incentives, but in Germany, those savings would come from certain annual tax exemptions that apply to PHEVs. Buyers in other countries might have more luck in getting into an A3 E-Tron for less. Audi lists its most important markets for the A3 E-Tron as Germany, Sweden, Norway, Holland, the UK and, despite no firm date for the car's arrival here, the United States. These countries, according to Audi, are where buyers are willing to spend their green (or the more colorful banknotes of Europe) on green cars. These places also enjoy nice things, or in Audi's words, "They appreciate the classic strengths of the Audi brand: high-end technology, uncompromising workmanship, sportiness and elegant design." In Germany, Audi will sell the A3 Sportback E-Tron at select dealerships. The service departments of those 100 or so dealers will get special training to work with the high-voltage technology used by the plug-in hybrid. These locations will also feature free-to-use charging stations for customers. The Audi A3 Sportback E-Tron's lithium-ion battery stores 8.8 kWh of juice, and is supplemented by a four-cylinder, 1.4-liter TFSI engine which works parallel to the electric motor. Total output is 204 horsepower and 258 pound-feet of torque, directed to the front wheels via a six-speed S Tronic transmission. The car can reach 60 miles per hour in 7.6 seconds and has a top speed of 138 mph. It can travel of to 31 miles on battery power alone. Deliveries for the 2015 Audi A3 Sportback E-Tron will begin in Germany and Central Europe this winter.
