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.

Spyker C8 Aileron to come back with supercharged power?

The new B6 Venator wasn't the only vehicle on display at the Spyker booth at the 2013 Geneva Motor Show. The company still has its C8 Aileron on offer, and Road & Track has word of a potential powerplant upgrade for the long-running machine.
Since its introduction in the year 2000, the C8 has used a 4.2-liter V8 engine sourced from Audi, which, in base form, offers up 400 horsepower. Though it's a great powerpant, that's simply not enough power in this day and age - after all, if a car is going to be called super, it needs to offer more ponies than something as mundane as the Ford Mustang GT.
According to R&T, John Walton, Chief Commercial Officer at Spyker, indicated that a new engine supplier may be in the works. "[The Audi-sourced V8] really hasn't got enough bang for the buck. To be honest, every supercar needs to have something that begins with a '5' today. That's why we're supercharging the car in the future, which will take it to over 500-hp," said Walton.

Audi Sport Quattro Concept to race into Frankfurt

Audi has pulled the official wraps off its new Sport Quattro Concept, which will be debuted at the 2013 Frankfurt Motor Show. The automaker is understandably keen to draw inspiration from its classic Quattro line of automobiles, specifically the original Ur-Quattro from 1980 and the short-wheelbase Sport Quattro that took part in rally racing and set a record at the Pikes Peak Hill Climb in 1987. A massive dose of modernity comes courtesy of its 700-horsepower plug-in hybrid powertrain.
There is a clear link in the styling of the Sport Quattro Concept to Quattro coupes of the past, from the large flat surfaces that make up its C pillars to the blisters over the fenders and the basic headlamp shape (equipped as they are with Audi's Matrix LED technology). Pay special attention to the car's grille, which introduces a slightly new design language that is expected to be seen in the next generation of Audi's mainstream production models.
The interior of the Sport Quattro Concept is a refreshing departure from Audi's admittedly attractive and useable design, with sharp lines and lots of visible carbon fiber. There are seats for four occupants inside, along with a comparatively generous cargo area measuring 10.59 cubic feet.
