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.

2016 Mercedes-Benz GLC250 First Drive [w/video]

There's nothing wrong with the Mercedes-Benz GLK other than old age, having first sold here in 2009. But with creased, off-road themed styling, a naturally aspirated V6, and a smallish interior, it's out of step with the company's growing line of sport utility vehicles. Even its name is a harsh-sounding outlier. Enter the 2016 GLC. Mercedes calls this model the second generation of the GLK, but it's closer to a total reboot. The new look follows the smooth design of contemporary Benzes. The spotlight engine is now a spunky turbocharged four cylinder, and yes, the GLC is bigger inside and out. As for the name change, that's part of the latest badge realignment, and the "C" indicates the GLC's position as the crossover counterpart to the C-Class sedan. Now firmly integrated into the Mercedes SUV family, the GLC takes a seat at the table between the entry-level GLA and the larger GLE. The GLC's fresh appearance has all of the tenets of modern Mercedes design. We've come to the Alsace region of France to sample this familiar yet evolved utility vehicle. Driving along route A35, we're immediately struck by the turbo four-cylinder's prowess. It's strong from launches when we mash the gas, returns a subtle but pleasing exhaust note, and it's more than capable of picking off slower moving traffic as we dash through the French countryside. We're driving the European-spec GLC250 model, which has the same 2.0-liter engine Americans will get in the GLC300, though the Euro model has 30 fewer horsepower. The US version will be rated at 241 hp and 273 pound feet of torque, the same output as the C300 sedan. The turbo has big shoes to fill, as it gives up 61 hp to the 302-hp V6 used in the GLK. Mercedes is banking consumers won't miss this raw power, as the GLC's inline-four offers the same amount of torque as the GLK's V6, but much sooner in the rev band. Even in its detuned European state, the I4 demonstrates the kind of urgency that Americans prefer for their grocery-getting people haulers. It's paired with a nine-speed automatic transmission, upgraded from the GLK's seven-speed. There are paddle shifters, though most Americans won't have reason to use them. Sometimes we grab them and lay on the throttle just for fun, and the GLC responds with bursts of speed. Even in its detuned European state, the I4 demonstrates the kind of urgency that Americans prefer for their grocery-getting people haulers.

Lewis Hamilton accepts Vettel's apology, has 'utmost respect'

SPIELBERG, Austria - Triple world champion Lewis Hamilton said he still had "the utmost respect" for Formula One title rival Sebastian Vettel after accepting a public apology from the Ferrari driver on Thursday. Speaking to reporters at a crowded Austrian Grand Prix news conference, the two men addressed a "road rage" controversy that has dominated the headlines since the June 25 race in Azerbaijan. "I still have the utmost respect for him as a driver and will continue to race him hard through the rest of the season," declared Hamilton, who said at the time that Vettel had "disgraced himself" by driving into him in Baku. He said Vettel called him on the Monday after the race and then texted an apology, which he accepted. The championship leader had driven into the back of Hamilton's Mercedes while both were following the safety car in first and second places, waiting for it to return to the pits. Vettel then pulled alongside, gesticulating angrily, before banging wheels. The German, a four times world champion, later accused Hamilton of "brake-testing" him by slowing suddenly. The car's telemetry subsequently showed that was not the case and Hamilton said the accusation was one he particularly wanted correcting. Vettel was handed a 10-second stop-and-go penalty, and finished fourth. He was then summoned to a hearing in Paris last Monday where the governing body declared the matter closed. Initially reluctant to dwell on the matter, saying he did not want to "pump this up more than it is already", the Ferrari driver on Thursday repeated the written apology. "It was the wrong move to drive alongside him and hit his tyres," he said. "I don't think there was any bad intention (by Hamilton). I don't think he actually brake-tested me. I was upset and over-reacted. I am not proud of the moment." Hamilton, 14 points behind Vettel after eight races, missed out on victory in Baku after a headrest worked loose and he had to pit. He finished fifth. Before Baku, the two world champions had made much of their mutual respect and the budding "bromance" seemed to be back on. "It's nice to hear that we are able to move forward," Vettel said. "I think the respect we have for each other on and off track helps us in this regard." Reporting by Alan Baldwin Related Video:
