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.

Toyota, Lexus dominate KBB's Best Resale Value Awards

Toyota and Lexus stormed the 2014 Kelley Blue Book Best Resale Value Awards, winning a combined 18 categories including best brand and best luxury brand. This marks the third year in a row that both automakers have won the Brand and Luxury Brand resale value awards. In all, Toyota won 11 categories and Lexus won seven.
Honda made a good showing, as well, winning two segments (Accord Plug-In Hybrid and Civic Si) and putting one car on the top-10 Best Resale Value list (CR-V). Chevrolet did even better, winning two segments (with the V6 Camaro and the Corvette) and placing three cars on the top-10-overall list (again, the Camaro and Corvette, plus the Silverado 1500).
The other winners came from Jeep, Dodge, Infiniti, Subaru and Audi. To give you a clearer picture of the Toyota and Lexus domination, their 18 mentions represents more than half of the 34 awards (including the top-10-overall list).

Audi Airomorph is a sleek shape-shifting senior thesis

Eric Kim just graduated from the from the Art Center College of Design in Pasadena, CA, at the end of the spring 2014 semester, and for his senior thesis project he came up with this futuristic Audi endurance racer called the Airomorph. He even got some input Audi designer Kris Vancoppenolle.
The Airomorph imagines a future Audi racer for Le Mans that features adjusting fabric panels to fine-tune the car's aerodynamics as it laps the course - a technology inspired by catamaran racing. "I started from scratch and had the freedom to deliver and execute a white space design for the future," said Kim to Autoblog via email. It's also somewhat similar to the idea behind BMW Gina concept, although Kim says that wasn't an inspiration for his design. The body here is made from a single piece of a silver, expansion-resistant material stretched over a frame underneath. The fabric anchors at the wheels, front and rear section with movable cables, and hydraulic actuators pull the wires to shift the aero as needed.
The actual shape echoes Audi endurance racers from the past and present. In profile, you can easily see the current R18 with its arcing cockpit and fin down the rear. Of course, that's interpreted through a little bit of Blade Runner with the covered wheels sticking out from the body. The front shows the rectangular shapes from the earlier R15. There doesn't appear to be any way to actually see out of the vehicle, though.
