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.

Recharge Wrap-up: Porsche 911 hybrid possible, Ecocruise EVs coming soon

The next-generation Porsche 911 could use hybrid power, according to Porsche CEO Matthias Muller. "There is no reason against it and we will see if we have some reasons to do it," Muller says of the model due around 2018. He also suggests that hybrid technology could eventually make its way into all Porsche model lines, but that the Boxster and Cayman would first get four-cylinder versions. Muller cites carbon emissions and "sportiness" as reasons to use hybrid power, pointing to the 918 Spyder as a good example of both. Read more at Car Advice. A B-Class F-Cell from the Mercedes-Benz fleet has hit a benchmark of 300,000 kilometers (about 186,411 miles) in everyday use. The achievement won Daimler an "f-cell award" for hydrogen fuel cell technology and innovation. The 300+ fuel cell cars in the Daimler fleet have driven a collective 9 million-plus kilometers (more than 5.5 million miles). The information gathered from this testing is being used to improve development as the company looks toward expanding commercialization of fuel cell cars. "We have clearly demonstrated that the fuel cell electric drive is ready for the road," says Professor Herbert Kohler of Daimler. "The last hurdles we will overcome in intensive cross-industry and cross-border teamwork." Read more in the press release below. A company called Ecocruise has new EVs coming out soon. Along with electric scooters and service vehicles, Ecocruise develops street-legal neighborhood electric vehicles like the three-wheeled EZip-3, the four-wheeled EZip-4, and the fun looking Cruser Sport (see a prototype in the video below). The EVs are scheduled to go on sale in January of 2015, which is right around the corner. Ecocruise was started after the founder of Kasea Motorsports decided to switch to electric vehicles with the goal of offering providing affordable emissions-free driving. Learn more about Ecocruise and its vehicles at the company's website. The new EU Fuel Quality Directive (FQD) does little to discourage dirty fuels like tar sands and coal-to-liquid, says Transport & Environment (T&E). The FQD requires suppliers to reduce greenhouse gas intensity for transport fuel in the EU by six percent by 2020. The much-delayed FQD doesn't do as much as it could, though, say critics, and it doesn't label dirtier fuel sources as such despite the urging of scientists. T&E, an organization focused on cleaning up EU transport, blames Canada, the US and Big Oil.

2013 Mercedes-Benz GLK250 Bluetec gets 33 mpg, priced from $38,950*

It's been more than a year since we first saw the 2013 Mercedes-Benz GLK250 Bluetec unveiled at the 2012 New York Auto Show, but it looks like the compact diesel crossover is finally starting to roll into dealerships. Those wanting to buy a diesel GLK will only have to pony up an extra $1,500 over a base, gas-powered GLK350, as the GLK250's starting price is listed at $38,590 (*not including $905 destination charge).
The turbocharged 2.1-liter four-cylinder diesel produces 200 horsepower and 369 pound-feet of torque, and Mercedes-Benz has also provided some fuel economy numbers for this model, with claimed EPA estimates of 24 miles per gallon city and 33 mpg highway. There is no listing for the GLK250 on the EPA's website yet, but the figures represent significant increase over the GLK350's lackluster 19 mpg city and 25 mpg highway figures, which are for the rear-wheel drive model. The GLK250 comes standard with the 4Matic all-wheel-drive system - a $2,000 option on GLK350 - meaning that if you want an all-wheel-drive version of the 2013 GLK, it's actually cheaper to opt for the diesel model. Head over to the Mercedes-Benz site for the full 2013 GLK-Class configurator.
