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.

Felicity Ace sinks with thousands of VWs, Porsches, Lamborghinis

The stricken ship Felicity Ace sank overnight after a week of salvage efforts ultimately proved unsuccessful. The ship, which was carrying up to 4,000 VW Group cars, went to the bottom unexpectedly while a salvage team was attempting to tow it to shore, Bloomberg reports.  "Initial reports from the local salvage team state that the vessel had sunk at around 9AM local time having suffered a list to starboard," Mitsui O.S.K. Lines transportation company (MOL), which owns the Felicity Ace, said in a statement released early Tuesday.    "The last vessel position was around 220nm off the Azores," MOL said. "The salvage crafts will remain around the area to monitor the situation. Further information will be provided as it becomes available." The ship sank after being battered by waves and listing 45 degrees to starboard, the ship’s operator said. “The weather was pretty rough out there,” Pat Adamson, a spokesperson for MOL Ship Management (Singapore), a unit of Mitsui OSK Lines Ltd., said by phone. “And then she sank, which was a surprise.” VW, Porsche, Audi, Bentley and Lamborghini-branded models were aboard the ship, which was headed to Rhode Island from GermanyÂ’s Emden port when the fire broke out on Feb. 16.  Rough seas and ongoing fires fueled by the lithium-ion batteries of EVs onboard delayed the ship's salvage and recovery operations for the better part of a week. While the likelihood of salvaging the smoke and potentially fire- and water-damaged vehicles from Felicity Ace's hold was slim to none, some had held out hope that their special-ordered vehicles might survive the mishap.  The Panama-flagged Felicity Ace was safely evacuated of its 22 crew members by the Portuguese navy after a fire started in its hold more than a week ago. The ship can carry up to 4,000 cars. European carmakers declined to discuss how many vehicles and what models were on board, but it appears to have been transporting approximately 2,500 cars, including roughly 1,100 Porsches and an undetermined number of Volkswagens.  The cars aboard were on order. Porsche customers in the United States were being contacted by their dealers, the company said. “We are already working to replace every car affected by this incident and the first new cars will be built soon,” Angus Fitton, vice president of PR at Porsche Cars North America, Inc., told The Associated Press in an email. The ship sank in water nearly 10,000 feet deep, the Portuguese Navy said.

Audi introduces frugal, 43-mpg Q7 Ultra in Europe

As Audi's largest model, you wouldn't expect the Q7 (standard 2017 model pictured above) to get very good fuel economy. But the new flagship crossover is a lot lighter than its predecessor. And now the German automaker is rolling out an even more efficient version. In Europe, at any rate. Bearing the designation that distinguishes the most fuel-efficient models that Audi offers, the new Audi Q7 Ultra 3.0 TDI Quattro packs a more frugal version of the 3.0-liter V6 turbo diesel. In Ultra spec, it produces 218 horsepower instead of 272, and 369 pound-feet of torque instead of 443. In exchange, it returns better fuel economy – now quoted at the equivalent of 42.8 miles per gallon (compared to 41.3 for the more potent version). That's not half bad for a crossover this large, even if it is on the European efficiency test, which returns higher numbers than what we're used to in the US. Of course, burning less fuel comes at a bit of a performance penalty: instead of 6.3 seconds, it now takes 7.1 seconds to reach 62 miles per hour from a standstill. Top speed is quoted at just over 134 miles per hour, down from 145. Of course, the E-Tron hybrid will be the most efficient model in the Q7 range, returning the equivalent of over 117 miles per gallon while reaching 62 in six seconds flat. That is, when it starts reaching dealers next spring. The kicker here is that while the hybrid is likely to emerge as the most expensive model in the range, the Ultra is the least. Its base price in Germany comes in at 58,000 euros, compared to 61,890 for the more potent TDI. Combine that with the fuel savings, and the Q7 Ultra is looking like the frugal choice indeed. New Audi Q7 as a highly efficient diesel - The Audi Q7 ultra 3.0 TDI quattro now available for order - Combined fuel consumption is 5.5 liters of fuel per 100 km - Base price is 58,000 euros in Germany An exceptionally efficient diesel version of the new Audi Q7 is launching on the market, which customers can now order: the Audi Q7 ultra 3.0 TDI quattro*. This engine not only reduces fuel consumption to 5.5 liters diesel per 100 km (42.8 US mpg); it also reduces the entry-level price for the Q7 model series to 58,000 euros. Audi will be delivering cars to dealers in Europe starting in September. The efficiency is ground-breaking: The combined fuel consumption of the 3.0 TDI with 160 kW (218 hp) is just 5.5 liters of fuel per 100 km (42.8 US mpg).
