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.

VW will expand goodwill package to larger diesels

Volkswagen Group of America will expand its goodwill package to affected owners of the VW Touareg and other models with the 3.0 TDI. The company may also replace the catalytic converter on some cars equipped with the 2.0-liter four-cylinder TDI engine to bring it into compliance with US emissions. VW Group of America boss Michael Horn told Reuters he plans announce the goodwill program's expansion to the 2009-2016 Touareg during the Detroit Auto Show, and company spokesperson Jeannine Ginivan also confirmed this to Autoblog. Audi intends to extend the offer to its affected owners, too. As with the previous goodwill package, participating customers would receive a $500 prepaid Visa card and $500 to use at dealers. The EPA issued a violation notice against the 3.0 TDI in November and later extended it to additional model years. Audi later admitted that the engine, which was also in the Touareg and Porsche Cayenne, had undisclosed emissions management software. However, the automaker limited the goodwill package only to the 2.0-liter powerplant while it investigated the allegations against the larger mill. VW has not announced a recall plan in the US for the 2.0 TDI so far, but VW Group CEO Matthias Muller recently outlined a possible solution that could fix about 430,000 of the 482,000 affected vehicles. "We have one [catalytic converter] in the works and we believe that will be a part of the technical solutions," he told Reuters. Muller plans to discuss the repair while in Washington D.C. on Wednesday to meet with the EPA. "I think we can now offer a package that will come very close to what the EPA is expecting from us," Muller said to Reuters. He also suggested the company might buy back some affected models but didn't confirm the recent rumor claiming that the buy-back may cover as many as 115,000 cars.

2015 Audi Q3 headed for Detroit before hitting US showrooms this fall

The market for small premium crossover vehicles continues to grow in popularity here in the US, and Audi is finally ready to get in on the action. Going up against competitors like the BMW X1, Land Rover Range Rover Evoque and soon-to-arrive Mercedes GLA-Class, Audi will unveil a US-spec version of the 2015 Q3 at the Detroit Auto Show next week. And in what we can only assume is an amusing coincidence, the Q3 will go on sale during Q3 of this year.
As we reported back in October, it appears that our Q3 will boast a slightly taller ride height than its European counterpart, but Audi isn't releasing too much information about the crossover just yet. What we know for sure is that it will be powered by Audi's well-liked 2.0-liter turbocharged TFSI inline-four producing 200 horsepower and 207 pound-feet of torque. A six-speed automatic transmission and front-wheel drive will come standard, while Audi's Quattro all-wheel-drive system will be optional.
Visually, the 2015 Q3 shown here has a different front fascia design than its European counterpart, but it's not immediately clear if this is exclusive to the US model or if it will be a new element for Q3 in all markets. We don't expect pricing to be announced until closer to its on-sale date, but the Q3 will definitely be stuffed with content, even in base form. Audi has already confirmed such niceties as a panoramic moonroof, Xenon headlights and heated leather seats. Delivering a good amount of practicality for its size, the Q3 will provide a maximum cargo capacity of up to 48.2 cubic feet and 16.2 cu-ft with the rear seats in place.
