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.

2018 Audi RS3 Sedan to make US debut in 2017 [UPDATE]

UPDATE: We've heard back from Audi, and the statement was as expected. According to spokesman Mark Dahncke, there's "nothing we can share at this time." We really want the Audi RS3 to come to the US market, and based on a report from Car and Driver, it doesn't sound like we'll be stuck waiting that long. The report claims the new compact rocket sedan will debut next year as a model year 2018 vehicle. Beyond that date, C/D's report expands on some of the details we reported on in our RS3 Sedan report from February. It backs up the claim about a 2.5-liter, turbocharged five-cylinder, but instead of a 400-plus-horsepower engine, C/D's report says it'd be "close to" 400 hp. That power would come from a turbocharged, 2.5-liter five-banger that's distinct from the unit currently offered in the Euro-market RS3 Sportback and the last-generation TT RS (the new 2.5 would first debut in that car's replacement). The new powerplant would be paired with Audi's seven-speed S-Tronic. According to C/D, all this powertrain goodness will allow the new RS3 to hit 60 in four seconds flat and run up to 174 miles per hour. If correct, that means Audi's newest high performer will be a tenth of a second faster to 60 and have an extra seven mph on the high end than the most potent Mercedes-Benz CLA45 AMG. And while the two-door BMW M2 isn't necessarily a direct competitor – because coupe – it's worth pointing out that the RS3 will be 0.2 seconds faster to 60 and have an extra 19 mph to its top speed. While C/D's report cites a "highly reliable source" for its information, we've naturally reached out to Audi to confirm as much as possible. We'll update this post as soon as Audi's PR team gets back to us. The company basically gave the usual "No comment."

Volkswagen decides to keep Lamborghini and Ducati, transfers Bentley to Audi

Investors in the market for a high-end Italian manufacturer that peddles performance will need to keep looking. Volkswagen announced it will hang on to Lamborghini and Ducati in the foreseeable future. Executives in Wolfsburg, Germany, are making far-reaching changes to the Volkswagen Group to reboot it with a big focus on technology. Credible rumors claimed that the people in charge of the carmaker wanted to carve out Lamborghini — which owns Ducati — and ultimately list it, or at least a chunk of it, on the stock market in order to fast-track the group's electrification strategy. Going electric is expensive, so selling Lamborghini would have helped fund the expansion, and high-octane supercars don't easily go hand-in-hand with zero-emissions cars. "Volkswagen needs to change from a collection of valuable brands and fascinating combustion-engine products that thrill customers with superb engineering to a digital company that reliably operates millions of mobility devices worldwide," summed up Herbert Diess, the group's boss, during a September 2020 meeting. His team ultimately decided not to fully divest both brands. It's too early to tell whether part of Lamborghini will be listed on the stock market, as some insiders have suggested, or if those plans are off the table, too. Changes are coming to Bentley as well. While it's not being spun off either, it will fall under the Audi umbrella starting on March 1, 2021. Volkswagen explained linking the two companies will "allow for synergies to be achieved as part of the electrification strategy of the two premium brands," a statement which suggests they will share a growing number of components during the 2020s. Unverified rumors claim that Bentley will notably get its own version of an ultra-luxurious electric SUV code-named Landjet that Audi is currently developing. We've reached out to Bentley for more details, and we'll update this story if we learn more. Bugatti's future wasn't mentioned in the release; unconfirmed reports suggest it will be traded for a stake in Croatian start-up Rimac. Volkswagen's supervisory board also reaffirmed its support for Diess, who was appointed CEO in 2018 and who has played a significant role in the company's transformation. Finally, the board approved the development of what a statement refers to a future leading electric vehicle sold by the Volkswagen brand that will be developed and manufactured in Wolfsburg.
