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:

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

The Mansory Speranza proves that money can buy taste and good sense...

...Just kidding.
No one in their right mind has ever accused German tuners Mansory of being subtle. So, when our Geneva team wandered across the Mansory Speranza - A Mercedes-Benz Gelandewagen that has been denuded of its roof and spackled inside with quilted leather and red carbon fiber ­- they didn't ask a lot of existential questions. Why does the Speranza exist? Because Germans are weird sometimes, that's why.
Forget for a moment that you'll have to pay Mansory hundreds of thousands of euros (we're guessing, no pricing information has been revealed) for the privilege of converting your G-Class into something that looks like a Suzuki Samurai, and prepare to be impressed by the details. The tuning house has increased the output of the Mercedes V8 to a healthy 700 horsepower and 668 pound-feet of torque. The wheels are 24-inches, and wear almost unbelievable 305-section ultra-high performance Vresdestein tires. Carbon fiber can be found nearly everywhere one looks, including making up the housing for the spare tire. Oh, and there are leather pillows for the backseats... no word on whether they're standard or optional, but we're looking in to it.
