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.

2019 Tokyo Auto Salon features one of the coolest auctions we've seen

In just over a week, the Tokyo Auto Salon will host one of the coolest auctions we've seen in years. Jalopnik spotted BH Auction's listings, and it's a cornucopia of hot machinery you won't typically find at American auctions like Gooding & Company or Barrett Jackson. While Japanese cars make up most of the listings, Ferrari, Porsche, BMW and even Dodge all have at least one car going up for auction. We won't include everything here, but you can check out the full list on BH Auction's website. There are 50 lots at the auction, including nine Nissan Skylines, nine Ferraris and two Porsche Carrera GTs. Some of our other favorites include a Honda S800 coupe, a Toyota Miniace truck, a Mitsubishi Willys Jeep and a 1955 Mercedes-Benz 300 SL gullwing with the V8 from a W124 Mercedes-Benz E60 AMG that's estimated to sell for between $1.25 million and $1.5 million.

Audi R8 LMX illuminates the City of Light with lasers

Hard as it may seem to believe, the Audi R8 has been around for the better part of a decade. But does that make us love it any less? Hardly, especially not when Audi keeps rolling out ever-more enticing versions like the one you see here.
Debuting at the Paris Motor Show, the new Audi R8 LMX is the most powerful version of the supercar we've seen yet, thanks to a 5.2-liter V10 engine tuned to deliver 570 metric horsepower. That's 562 by our count, making it ten horses more potent than the R8 GT, or 37 more than the standard ten-cylinder R8 5.2 FSI - enough to propel the LMX to 62 in 3.4 seconds.
That's not all that sets the LMX apart, however, as Audi has fit it with cutting-edge laser-beam headlights. It comes exclusively as a coupe in Ara Blue with carbon fiber trim, special wheels, red brake calipers and a black leather cockpit. Only 99 examples will be made, and with those laser headlights banned in the US, your best chance of seeing one is in the gallery of live images above.
