Volkswagen preparing Tiguan Coupe R

Volkswagen has might proliferation plans for the SUV side of the VW brand, Autocar listing a range that will comprise seven models and variants on sale by 2018. The next-generation Tiguan will play a large part in tripling VW's crossover lineup, a development discussed a year ago, with a standard model, the three-row long-wheelbase version to be built in Mexico, and a five-door "Coupe" variant that will get an R version worked up by the in-house R team. The Tiguan Coupe R is aimed at the performance end of the compact crossover field, giddyup coming from a 2.0-liter four-cylinder with something like 300 horsepower and 280 pound-feet of torque that works through a six-speed dual-clutch transmission. Underpinnings are expected to be cribbed from the Golf R; a hotter suspension tune with a lower ride height and four-mode damping. The sprint to 62 miles per hour would clock in around 5.1 seconds, and handling nous would be aided by all-wheel drive and electronic torque vectoring. It will need all of that in order to catch up to the competitive set listed by Autocar of the 375-hp Mercedes-AMG GLA45, 309-hp Audi RS Q3, and potential Range Rover Evoque SVR and BMW X2 M. The CrossBlue Coupe seen in Shanghai earlier this year will provide the styling cues, we're told, with rakish glass front and back, and thick C-pillars supporting a leaner greenhouse. We'll likely see the basic Tiguan at next month's Frankfurt Motor Show, then will come the long-wheelbase in 2016, the regular Coupe in 2017 along with the Touareg and US-built CrossBlue, then in 2018 the Tiguan Coupe R, CrossBlue Coupe, and Nissan Juke-fighting T-Roc.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

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.
