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.

Mercedes-Benz intros long-wheelbase E-Class for China

Long-wheelbase sedans are a pretty hot commodity in China, and to keep up with the competition, Mercedes-Benz has introduced an extended version of the 2014 E-Class sedan at the Shanghai Motor Show. Audi, BMW, Volvo and even Cadillac offer extended versions of sedans specific to the Chinese market, and now the E-Class L, shown off in E400L guise, will give luxury sedan buyers in China yet another option.
Compared to the standard 2014 E-Class sedan, the new China-spec E-Class L has been stretched by 5.5 inches - all of which goes to the rear-seat passengers. According to an article on China View from earlier in the year, the market for chauffeur-driven cars is growing in the Asian nation, so automakers need long-wheelbase models like the E-Class L in order to fully compete. As for what powers this stretched E-Class, it's available in three models: the diesel E260L, the V6-powered E300L and the E400 Hybrid.
The redesigned E-Class and the all-new A-Class are just the first of 20 new Mercedes-Benz products that will be introduced into the Chinese auto market by 2015. Scroll down for the full press release on long-wheelbase E.

Mercedes making aggressive plans for Chinese market

Mercedes-Benz is preparing a major product offensive to counteract lagging sales in the Chinese market, aiming 20 new or updated models at the People's Republic in the next two years, according to a report by Reuters. The plan is part of MB's so-called 2020 Initiative, which will see the Stuttgart-based manufacturer dump 2 billion Euros ($2.67 billion) into its Chinese market vehicles in a bid to boost sales to 300,000 units by 2015.
Were it to succeed, China would become the largest market for the Silver Arrow, outpacing Germany and the United States. Leading the charge will be the redesigned E-Class, which is set to launch in China this week. That will quickly be followed by the S-Class, and eventually by the GLA-Class in 2014.
Mercedes has struggled in China, especially relative to its German competition, BMW and Audi. Where Mercedes saw a mere four-percent increase in 2012 sales to 206,150 units, Audi was up a staggering 32 percent, while BMW's numbers jumped 41 percent. While some voices, according to Reuters, accuse Munich and Ingolstadt of boosting their numbers through hefty incentives, the fact remains that Mercedes was just walloped by its competitors last year.
