VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

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.

Car and Driver shows off awesome 1960s ads

Someone must have recently rediscovered the keys to the archives at Car and Driver, and the access has been put to good use. Following last month's fantastic look at automotive ads from the '50s, there's now a new gallery running from March 1960 through December 1969. This collection provides a great overview of a decade full of iconic cars. If you're a fan of Carroll Shelby, particularly his Mustangs, then there's a lot to love among this group. One ad from July 1965 aimed to sell the GT350, but with an ocean of text and a tiny picture, it probably could've used a once-over by Don Draper's team. By December '65, the copywriters ironed out the problems with a spot proclaiming boldly "Shelby GT350 is 'Son of Cobra.'" The company offered some great accessories, too. For those into European motoring, there's a humorous attempt to sell the Alfa Romeo Giulia as both a racecar and family hauler. Toyota also boasts about the winning record for the 2000GT. Among the best text comes from BMW for lines like: "What's BMW got? The most advanced high-performance engine in any production car, for a cruising speed of 100 mph." Of course, Volkswagen's famous "Lemon" ad for the Beetle also gets its due here. Separately, each of these ads is fascinating, but taken together they tell the story of a great decade of motoring. Go give them all a read at Car and Driver.
