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, BMW Z4 top Total Value Awards by Strategic Vision

It was just nine months ago that Strategic Vision announced its 2011 Total Value Awards, but you don't have to wait until next year for the 2012 awards. The Volkswagen Group keeps its lead as the number one brand, with seven products taking top category spots: Golf, Jetta Wagon, CC, Eos and Audi A3 Wagon, Q5 and Q7. Strategic Vision says "true innovation" - "rich and impactful, intuitive, motivational, in-depth and is able to trigger description by the user in great specificity" - is the open secret of the brands with the strongest showings. Results are culled from 77,153 owners covering more than 350 new cars bought between September of 2011 and 2012 ranked in the Total Value Index (TVI).
Other notable winners are Hyundai-Kia following VW in the brand category and having the Hyundai Elantra and Kia Sorento among category winners, the BMW Z4 taking the premium roadster category and the highest overall score of any vehicle, the Chevrolet Volt continuing to gather silverware in the Special Category, nabbing the second-highest score of all and representative of "nearly perfect innovation," and Chrysler and Dodge being most improved.
Check out the press release below for your day's dose of jargon and all the winners.

Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.
