Which will Dieselgate hurt more, Volkswagen or US diesels?

The most damning response to the news Volkswagen skirted emissions regulations for its diesel models may have actually come from the Los Angeles Times. On Saturday, the Times published an editorial titled "Did Volkswagen cheat?" The answer was undoubtedly yes. When you can't drive down Santa Monica Boulevard without seeing an average of one VW TDI per block, the following words are pretty striking: "... Americans should be outraged at the company's cynical and deliberate efforts to violate one of this country's most important environmental laws." VW has successfully cultivated a strong, environmentally conscious reputation for its TDI Clean Diesel technology, especially in states where emissions are strictly controlled. A statement like that is like blood all over the opinion section of the Sunday paper. The effect on VW's business, even Germany's financial health, was already felt Monday when the company's shares plummeted 23 percent in morning trading. The statement on Sunday from VW CEO Dr. Martin Winterkorn says "trust" three times. That probably wasn't enough in nine sentences. Writers over the weekend have compared VW's crisis to one at General Motors 30 years ago, when it was the largest seller of diesel-powered passenger cars until warranty claims over an inadequate design and ill-informed technicians effectively pulled the plug on the technology at GM. In a sense, VW is in the same boat as GM because it has fired a huge blow into its own reputation and that of diesels in passenger cars. And just as automakers like Jaguar Land Rover, BMW and, ironically, GM, were getting comfortable with it again in the US. VW of America was already knee-deep in its other problems this year. Its core Jetta and Passat models are aging and it needs to wait more than a year for competitive SUVs that American buyers want. The TDIs were the only continuous bright spot in the line and on the sales charts. Even as fuel prices fell and buyers shunned hybrids, VW managed to succeed with diesels and show that Americans actually care about and accept the technology again. Fervent TDI supporters might actually lobby for that maximum $18 billion fine to VW. I've personally convinced a number of people to look at a TDI instead of a hybrid. Perhaps not so much for stop-and-go traffic, but I know buyers who liked the idea that a TDI drove like a normal car and wasn't packed with batteries.

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

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.
