1,682 miles in a 2014 Audi A8 L TDI - Part 2

Interruptions like the Canadian Grand Prix, Le Mans, Pikes Peak, that ridiculous Porsche 911 GT3 and the really good, really outrageous Jeep Cherokee, are among the distractions that delayed the conclusion of this tale. If you'll remember, in Part 1 we started off in a parking lot in Sebring with an Audi A8, headed anywhere that would empty our tank, and after five days in Miami and Ft. Lauderdale and Pompano Beach we bolted in the middle of the night for a breakfast date at an IHOP a couple hundred miles away.
We last left proceedings at a Chevron pump beside the West Florida Turnpike, somewhere around midnight in the humid wilds, having done 660 miles and spent $89.40 to put 20.992 gallons in the great white whale. We had done average speed of 31 miles per hour at an average rate of 27.5 miles per gallon. Those kinds of numbers, as we demonstrated, are good enough to put you in the fuel economy orbit of the Toyota Corolla - to be precise, it only cost $6.40 more to cover that 660 miles in the A8 TDI than it would in the Japanese compact. That led us to conclude that there were just a couple of Starbucks Venti lattes between the A8 and the Corolla, assuming we conveniently ignore the two cars' purchase prices. Turns out we were wrong: it didn't take long for a commenter named "mike" to set us straight when he wrote, "It's clear you weren't lying about not frequenting Starbucks...no way could you get two venti lattes for $6.40." Mike, we salute you - our ignorance of terrible coffee has served the higher purpose of emphasizing the strong case made by the diesel Audi.
But that A8... well, the wheels were still on the damn thing and we had to drive them off. That meant five more days of pilot duty to get us from wherever the hell we were to Wildwood and Daytona Beach, FL, then Brunswick, Macon and Atlanta, GA, then Birmingham, AL, and back to Atlanta.

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 gets Q2 and Q4 badges in trademark swap with FCA

Audi has swapped trademarks with Fiat Chrysler Automobiles to snare the rights to the Q2 and Q4 badges for upcoming crossover SUVs. Audi CEO Rupert Stadler confirmed at the Detroit Motor Show that the automaker had finally persuaded FCA to release the two names that would let Audi lock up the Q1 to Q9 badges for its growing SUV family. Audi already plans to drop the Q2 name onto its MQB-based city crossover five-door this year, while the Q4 badge will slot onto the rump of a coupe-like version of the next Q3. It will also reserve the Q1 badge for a 2018 baby crossover, based around the architecture of the next A1 hatch. The A1 will share a lot of its engineering with Volkswagen's Polo-based soft-roader, dubbed T-Cross in concept form. The German company has also pounced on the naming rights for SQ versions of all of its Q-cars, along with F-Tron to cover the day when it pushes hydrogen fuel cell cars into production. Stadler insisted that no money had changed hands in order to pry the two badges off FCA, admitting that they had "each found something we needed." "We promised each other we wouldn't disclose what it cost, but it was not something they were willing to sell," Stadler said. "We tried to get it years ago and they said 'No, never,' but there is never 'never' in business. ... This year I went back to them with a proposal and we talked and there were some negotiations and then we agreed to it." Those negotiations are believed to have centered on a trademark swap with a Volkswagen Group name that FCA desperately (evidently) wants to use on a Fiat, Alfa Romeo, Chrysler, Dodge or Maserati. Asked if Audi had given FCA a trademark in return for Q2 and Q4, Stadler replied, "Something very much like that, yes." Audi has used Italian names on past concept cars that FCA could be interested in, such as the 2001 Avantissimo concept and the 2003 Nuvolari coupe. The latter was named after legendary pre-war racer Tazio, who won grands prix for both Alfa Romeo and Audi's forerunner, Auto Union. Both are unlikely trade chips, with laws in Europe preventing the trademarking of the names of actual people. There is always "quattro" (Italian for "four"), but after investing nearly four decades locking it in as an Audi all-wheel-drive name, it's just not anything like trade bait.
