Mercedes-Maybach G650 Landaulet is the ultimate safari machine

Update: A Mercedes representative has informed us that the Mercedes-Maybach G650 Landaulet will not be available in the United States. The text has been updated to reflect this. Vehicles such as the Mercedes-Benz G63 AMG 6x6 and G500 4x42 are all well and good, but they have one key issue: They simply aren't extravagant enough. Now we know that sounds insane because one of those vehicles has six driven wheels and the other is available in tennis-ball green. But they must not be decadent enough because Mercedes went a step further with the new Mercedes-Maybach G650 Landaulet. While the most obvious change here is the soft-top, which will make this perfect for the wealthy to view wildlife on private safaris, we should start under the hood. The previous two monster G-Wagens made do with lowly V8s. This one features a twin-turbocharged V12 making 630 horsepower and 738 lb-ft of torque. Like its predecessors, this G650 uses a four-wheel-drive system with front, center, and rear differential locks, and sends power to solid portal axles front and rear. These axles move the differential and drive axles above the wheel centers for additional ground clearance. Inside, the rear passengers will be in the lap of luxury, even while the driver is navigating particularly harsh terrain. The soft top can be electrically raised or lowered, as can a glass partition to the driver's compartment. The two individual rear seats can be fully reclined, and leg rests deploy from below, taking full advantage of the truck's long wheelbase. This would likely make for an amazing vehicle for stargazing. The passengers also have access to folding tables, 10-inch LCD displays, and heated, cooled, and illuminated cup holders. Only 99 of these G650s will be built. Mercedes will show the SUV at this year's Geneva show, and it will hit the market this fall. Mercedes hasn't announced pricing, but expect it to be exorbitant. Not that matters for American buyers, since a Mercedes representative told us it won't be offered in the States. For buyers in countries where the G650 will be available, they will have the option of four interior color schemes, three soft-top colors, and four paint hues. Related Video:

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: Smart Silvretta E-Car Rally, Uber's autonomous Teslas

Daimler took part in the 2015 Silvretta E-Car Rally with seven electrified cars from Mercedes-Benz and Smart. It is the automakers' sixth year competing in the competition in the mountains of Austria's Montafon region. Mercedes fielded two B-Class Electric Drives, an SLS AMG Electric Drive, C350e, S500e and GLE500e 4Matic alongside a Smart Brabus Fortwo Electric Drive Cabriolet. The Silvretta Rally sees some 150 vintage cars and 30 electric vehicles take part in the event, which took place from July 2 through 5 this year. Read more in the press release from Daimler below. Uber CEO Travis Kalanick says that he'd want to buy all of Tesla's autonomous vehicles if they were available in 2020. Venture capitalist Steve Jurvetson relayed Kalanick's comments from the Top 10 Tech Trends dinner in June. Jurvetson also praises self-driving cars, saying, "I believe they are already safer than my parents, and I would trust my kids with them. And they're just going to get better." Jurvetson also believes that taxi services will prosper from the use of autonomous cars in the future. Read more at Hybrid Cars. A Michigan legislator has introduced a bill that would count burning industrial solids — such as tires and plastics — toward the state's renewable energy mandate. Aric Nesbitt's bill would "remove unnecessary burdens on the appropriate use of solid waste as a clean energy source" in order to meet the state's requirement that 10 percent of energy come from renewable sources. Critics argue that these materials are not truly renewable, and that burning them causes pollution and emits greenhouse gases. The proposed bill would also repeal a law requiring utilities to work toward reducing energy use by one percent per year. Read more at Treehugger. Will the cars National Electric Vehicle Sweden (NEVS) builds in China bear the Saab name? While NEVS is the newest parent company to Saab after being acquired in bankruptcy from Spyker, there's no confirmation that the electric vehicles it builds at its Tianjin plant will be sold as Saabs. Swedish defense firm Saab AB, which held the rights to the Saab name, withheld permission to use it after NEVS declared bankruptcy last year. "The exact models and brands are not finalized yet," says a NEVS spokesman. The company says it is spending $200 million to build the new factory in China, with an expected annual capacity of 200,000 vehicles. Read more at Automotive News Europe.
