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.

Coronavirus prompts VW to stop production throughout Europe

FRANKFURT — Volkswagen Group, the world's biggest carmaker, is suspending production at factories across Europe as the coronavirus pandemic hits sales and disrupts supply chains, the company said on Tuesday. The German carmaker, which owns the Audi, Bentley, Bugatti, Ducati, Lamborghini, Porsche, Seat and Skoda brands, also said that uncertainty about the fallout from coronavirus meant it was impossible to give forecasts for its performance this year. "Given the present significant deterioration in the sales situation and the heightened uncertainty regarding parts supplies to our plants, production is to be suspended in the near future at factories operated by group brands," Chief Executive Herbert Diess said on Tuesday. Volkswagen's powerful works council concluded it was not possible for workers to maintain a safe distance from each other to prevent contagion and recommended a suspension of production at its factories from Friday. Production will be halted at VW's Spanish plants, in Setubal in Portugal, Bratislava in Slovakia and at the Lamborghini and Ducati plants in Italy before the end of this week, Diess said. Most of its other German and European factories will prepare to suspend production, probably for two to three weeks, while Audi said separately it would halt output at its plants in Belgium, Germany, Hungary and Mexico. Volkswagen's vast factories in Chattanooga, Tennessee, in Puebla, Mexico, and plants in Brazil were not affected, but that would depend on how the coronavirus spreads, VW said. Volkswagen has 124 production sites worldwide of which 72 are in Europe, with 28 in Germany alone. "2020 will be a very difficult year. The coronavirus pandemic presents us with unknown operational and financial challenges. At the same time, there are concerns about sustained economic impacts," Diess said.   Production in China resumes Volkswagen Group sold 10.96 million vehicles last year, putting it ahead of Toyota based on the latest figures from the Japanese carmaker. Globally, VW employs 671,000 people and it delivered 4.86 million vehicles to European customers in 2019. Only last month the car and truck maker based in Wolfsburg, Germany, predicted that vehicle deliveries this year would match 2019 sales and forecast an operating return on sales in the range of 6.5% to 7.5%. "The spread of coronavirus is currently impacting the global economy. It is uncertain how severely or for how long this will also affect the Volkswagen Group.

Audi S3 with manual transmission still on table for US

The fine folks at Fourtitude recently sat down with Audi of America President Scott Keogh, and among other things, learned that the potent little S3 sedan could be offered with a manual transmission in the United States someday. That sort of sounds like the usual company line to us, but Keogh reportedly said the company is "looking very closely" at adding the manual to the S3, which currently is only available with a dual-clutch automatic.
Fourtitude also brought up the possibility of a hotter RS3 - a vehicle we've seen testing before, as a hatchback. We don't doubt that this more potent compact is already a done deal, but Keogh reportedly mentioned that the sedan will get this treatment. An RS3 for the US? Sign us up, for sure.
Head over to the Audi enthusiast site to read more from their talk with the company's US boss.
