Buy a V8 Mercedes-Maybach, or splurge for a V12? Oh to have such problems

There's a certain air that surrounds the Maybach badge, and it's not just the scent being pumped out by the ionizer in the car's glovebox. It's the cream of the crop when it comes to German luxury. These cars are filled with an acre's worth of wood and a herd's worth of cows, ensuring your fingers rarely touch materials as pedestrian as plastic. It's as quiet, as smooth, and as imposing as you think it would be. Though the latest model from Mercedes-Maybach, the S550, might have swapped in a V8 and all-wheel drive in place of the V12 at the heart of the S600, no other amenities have been lost in translation. The car's size gives it a certain presence. Staring at the profile shows a wheelbase that spans two counties, necessitating a microphone and speaker setup simply so that the driver can converse with the passenger – and a Maybach will almost always have a passenger. No one buys a Maybach to drive. You buy a Maybach to be driven. No means of transport short of business-class airline seating offers this much space. Sit back, recline the seat, roll up the shades and enjoy your $167,125 cocoon. But you know all of that already. What you really want to know is if $25,000 - the V12-powered S600 starts at $192,225 - is worth it to gain an extra four cylinders, 74 horsepower, and 96 lb-ft of torque. On paper, no, it's not. The two cars have identical performance numbers, and the S550 benefits from Mercedes' 4Matic all-wheel-drive system. Even with all-wheel drive, the S550 weighs less than the nose-heavy S600. Fuel economy is, as expected, superior in the S550. It's rated at 16 city, 24 highway and 19 combined as opposed to 13 city, 21 highway, and 16 combined. Visually, the two cars are identical save for a few badges. The V12 badge on the S600 is replaced with a 4Matic badge on the S550, and that's where things start to get murky. When you're spending six figures on a car, decisions become more emotional than practical. $25,000 is a lot of money, but there's a bigger difference between $25,000 and $50,000 than there is between $167,000 and $192,000. As stated, you don't buy these cars to drive. Performance needs to be merely adequate. A smooth, torquey V12 is likely preferable to a hairy-chested V8, refined as it may be. These cars will never touch redline, lest the passengers spill their champagne. Plus, that V12 badge is worth its weight in country club memberships. Driving an S550 is fine until an owner shows up at an event behind an S600.

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 working on S-Class EV in accelerated green car lineup?

With Mercedes-Benz bringing out coupe and plug-in hybrid versions of its S-Class sedan, the German automaker just may follow through with a battery-electric variant as well. That's what the company's Uwe Ernstberger told the folks at Top Gear during the Geneva Motor Show. And while he noted the company still needs to work in a larger-than-usual battery pack and was less than specific with details, he did envision an all-electric S-Class "in the future." Of course, rumors started bubbling about an EV S-Class as far back as 2011, so we'll see. Christian Bokich, department manager for product and technology communications for Mercedes-Benz USA, would not confirm anything about an electric S-Class, but he did give AutoblogGreen an official rundown of MB's upcoming green cars in the US, starting with the launch of the all-electric B-Class ED in July of this year in the ZEV states (launch details for other states are TBA, he said). An S-Class plug-in hybrid is coming in the first half of 2015, followed by a C-Class PHEV closer towards the end of that year in the USA. There is also a C-Class four-cylinder BlueTEC coming at some point in 2016. Until we get more concrete information about the possible S-Class EV, let's review what we know about the PHEV. Last September, Mercedes-Benz started showing off the plug-in hybrid S-Class, saying that it could go as far as 19 miles on electric power alone and had a preliminary fuel efficiency rating of more than 78 miles per gallon, using the more lenient European driving cycle. Earlier this week, Mercedes showed off its S-Class Coupe. That model's US version will have a twin-turbocharged V8 that kicks in 449 horsepower, a few more than the presumptive S-Class EV will have. Ernstberger also said Mercedes would join the ranks of automakers offering autonomous driving systems and mentioned the S-Class as being at the "top of the movement." He held his tongue when asked about the possibility of an S-Class cabriolet.
