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 CEO says brand's EVs are almost as profitable as its other cars

After, oh, a hundred years or so of building vehicles primarily powered by internal combustion engines, automakers around the world have been and still are pumping billions of dollars into the development of electric vehicle technology. Everything from platforms and batteries to motors and the software to control it all requires untold hours of development, and that takes time and money. Fortunately, it's not going to take long for that massive investment to start paying off, at least according to Audi CEO Markus Duesmann, who told Reuters in an interview that "The point where we earn as much money with electric cars as with combustion engine cars is now, or ... next year, 2023. They are very even now, the prices." As a brand, Audi contributed more than a quarter of overall profit for the massive Volkswagen Group, which has such powerhouse brands as Volkswagen and Porsche among others. Under the Audi umbrella are Lamborghini, Bentley and Ducati, and it seems those high-end branches aren't going anywhere, at least for now. "These brands ... are very valuable very profitable brands, where we can even expand the synergy level in the future," Duesmann said in the interview. "There are no plans whatsoever to get rid of them." Despite the overall profitability of the brand, the ongoing global chip crisis is causing headaches. "We had a very strong first half in 2021. We do expect a much weaker second half," said Duesmann, who added, "We really have trouble." In fact, so serious is the trouble that the brand is forced into "a day-to-day troubleshooting process" to limit the chip-shortage damage. The good news for the automaker is that Audi has been able to boost its profit margin from 8% prior to the pandemic in 2019 to 10.7% in the first half of 2021. The bad news is that various chip shortages aren't expected to get a whole lot better over the rest of the year. Related video:

Bathurst 12-hour gallery is GT3 heaven [w/video]

The 2015 Liqui-Moly Bathurst 12-Hour race was run this weekend at the Mt. Panorama Circuit in Bathurst, Australia. Race photographer Joel Strickland sent us a huge batch of photos, all of which make us salivate for the switch to GT3 rules in the United SportsCar Championship; the top seven finishers at Bathurst were of seven different makes: Nissan GT-R NISMO GT3, Audi R8-LMS Ultra, Aston Martin Vantage GT3, Bentley Continental GT3, Mercedes SLS AMG GT3, Ferrari F458 Italia and Lamborghini Gallardo. It was a sweet victory for the No. 35 car driven by the NISMO Athlete Global Team after it crashed in Saturday qualifying, and then was only in third place on the penultimate lap. The three-man driving team included two GT Academy winners, one of whom, Florian Strauss, has only been a professional race car driver for 18 months. It's the first time the GT-R has won at Panorama since the original R32 "Godzilla" took back-to-back wins in 1991 and 1992. Second place went to the No. 15 Phoenix Racing Audi R8-LMS Ultra, 2.4 seconds behind the winners, third to the Craft Bamboo Racing Aston Martin Vantage not even half a second behind the Audi. The Bentley Motorsport team, in its first Bathurst 12-Hour with two cars, had its No. 10 Continental GT3 in the lead until the penultimate lap and in second place until the final corner, but crossed the line in fourth after some rubbin'-is-racin' action from chasers. And if pictures aren't enough, as of writing you can still watch the live stream of the entire race at the Bathurst 12-Hour site. Or, if you don't have the time, at least be sure to check out the last five minutes, below. Enjoy.
