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.

Audi Allroad Shooting Brake showcar is a 124-MPGe hybrid E-Tron

The leaked images of the new Audi Allroad Shooting Brake that came out Friday showed us what the show car will look like, but it wasn't until the official press release came out today that we learned just how much E-Tron is hiding in its powertrain. Turns out, it's a lot. An 8.8-kWh lithium-ion battery can power the car for over 31 miles. The Allroad Shooting Brake is powered by a hybrid (gas-electric) powertrain that can put out a total of 300 kW of power (479.42 pound feet of torque) and, under the right circumstances, get the fuel efficiency equivalent of 123.8 mpg US, Audi claims. The gas side is made up of a 2.0-liter four-cylinder turbocharged engine, and then there's an electric motor on each axle. An 8.8-kWh lithium-ion battery can power the car for over 31 miles on battery power alone. There are three drive modes (EV, Hybrid and Sport). This is also the first time Audi has put its Allroad and E-Tron "form languages" together, which means this E-Tron Quattro "is not limited to paved roads" and can handle "light off-road conditions." The two electric motors help bring the car from 0-62 miles per hour in 4.6 seconds on up to a top speed of 155 mph. Audi has paid attention to shaving weight from the 3527-pound, four-seater, including making the wheels out of carbon-fiber reinforced polymer (CFRP) and using an aluminum underbody panel. We described some of the concept's visual hints in the original post (Q1?), and now Audi says that the car contains "a host of visual elements of future sports car models" (TT?). We will get our first real glimpse of the Allroad Shooting Brake show car at the Detroit Auto Show early this week, so look for live pics then, especially of the interior that is supposed to be reminiscent of an airplane and a user interface panel that is said to work like a smart phone. In the new press release, Audi's Ulrich Hackenberg said the Allroad Shooting Brake represents, "a concrete look into the near future," and we're totally fine with that. Crossover in a compact package: The Audi allroad shooting brake show car Crossover concept car is highly functional for recreational sports Powerful and efficient hybrid drive features two electric motors Prof. Dr. Ulrich Hackenberg: "A concrete look into the near future." Sporty, compact and versatile: It is with these attributes that the Audi allroad shooting brake makes its debut at the North American International Auto Show (NAIAS) in Detroit.

Volkswagen profit jumps as it warns of a cooling auto market

FRANKFURT, Germany — Volkswagen says its profits jumped 44% in the third quarter thanks to a more profitable mix of vehicles in its lineup but warned that global car markets are slowing more than expected and lowered its forecast for annual sales. After-tax profit rose to $4.42 billion (3.98 billion euros) as revenues rose 11% to $68.27 billion (61.42 billion euros). The sales margin of 7.8% exceeded the goal of 6.5-7.5% as vehicles bringing higher profits took a larger share of sales. The Wolfsburg-based automaker pointed to the headwinds facing the industry by saying that it expects "vehicle markets will contract faster than previously anticipated in many regions of the world." It said sales would be "on a level" with last year's record of 10.8 million vehicles. Previously it had expected a slight increase. The company said its profits would be in the lower end of its forecast range. Global automakers are facing a slowdown in sales amid disputes over trade and from pressure in the European Union and China to develop and sell low-emission vehicles that require heavy investment in new technology. Ford and Renault have issued profit warnings in recent days, while Daimler, maker of Mercedes-Benz luxury cars, lost money in the second quarter and is expected to outline a cost-cutting strategy for investors on Nov. 14. Volkswagen is leading the push into electric vehicles in Europe by launching its ID.3 battery-powered compact car at prices it says will make zero local emission vehicles a mass phenomenon. The company was able to increase earnings in the quarter despite an 18% rise in spending on research and development.
