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.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.

Audi A3 E-Tron could launch in October in US

When we test drove the Audi A3 E-Tron plug-in hybrid in Europe last summer, Audi was talking about the vehicle's introduction in the US, but left the exact date up in the air. Summer or Fall 2015 was as specific as anyone was willing to get. Now it looks like the plug-in will arrive in October. One of the rumors we heard over the last few months was that the A3 E-Tron was not ready for the US because of poor cold-weather performance. From what we've heard, under a certain temperature limit, the engine needs to kick in at all times, no matter what the battery state of charge is, and some European A3 E-Tron owners are disappointed that their EV sometimes isn't all that electric. Audi's solution needs to take into consideration how to balance utilization of battery power in less-than-optimal temperature ranges with passenger comfort and how any excess battery use impacts longevity. Audi's "fairly conservative" position will "ensure the long-term credibility of the E-Tron platform and plug-in technology." - Brad Stertz Brad Stertz, the corporate communications manager for Audi of America, told AutoblogGreen that, "Audi is taking a fairly conservative position to ensure the long-term credibility of the E-Tron platform and plug-in technology, while still creating the best experience for our drivers in each region. Overall, I think it is safe to say low temps affect performance in all vehicles to some degree, but that plug-ins face unique challenges that we will continue to work through with the A3 e-tron and other plug-in models to follow." Stertz also said in April that the US configuration for the A3 E-Tron was still being fine-tuned. For example, there were some software differences under consideration to meet US driving preferences. Looks like we only have four more months to wait and see. Related Video:
