Mercedes G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.

New Mercedes Unimog debuts to the cheers of little boys everywhere [w/video]

The Mercedes Unimog, the superhero villain of the off-road world that's just waiting to make the jump to Transformer, has been completely upgraded for its new generation. There are ten models, expanding the range and getting new designations across the traditional all-terrain series and the implement-carrier series. Panoramic cabins get more visibility, multifunction steering wheels and better dash clusters, improved HVAC and a three-mode central tire inflation system. Outside, there are new items like LED headlights and daytime running lamps in the bumper, roof-mounted windshield wipers and a front-camera monitor for the implement carrier.
The new engine lineup is compliant with Euro VI, featuring four- and six-cylinder BlueEfficiency engines putting out anywhere from 156 horsepower to 354 hp. Powerplant placement has also been tweaked, the chassis members getting a revised curve to place the engine a bit further back and lower, maintaining off-road clearance and lowering the Unimog's center of gravity. The new location of the engine means the cabin has more room, and the wheelbase is shorter. Combined with a higher turning angle, the Unimog has a smaller turning radius than before.
The implement carrier gets what's called a "synergistic traveling drive," the bonus being that drivers don't need to stop in order to use an attachment - a hydrostatic transmission works with the regular manual transmission at up to 31 kilometers per hour for seamless switching.

Mercedes working on new inline-six engines

Mercedes-Benz will make a return to the inline-six-cylinder engine game, according to a report from the UK's AutoCar. It's not clear what's prompting the phasing out of the current array of V6s.
We'll see the first inline-six from Mercedes in next-generation E-Class, set to debut in 2016. Following that, it'll arrive as part of a mid-cycle refresh for the C-Class in 2017. What's particularly special about the new inline-six is its modular nature, which will allow Mercedes to eventually spinoff three- and four-cylinder options, with the three-pot arriving alongside the new inline-six.
In other news, AutoCar uncovered some details on the next C-Class AMG, which will ditch its excellent 6.2-liter, AMG V8 in favor of a 4.0-liter, twin-turbocharged V8, although we've already told you about that. What we didn't know at the time, though, was that the 4.0-liter would be paired first with a new, seven-speed AMG Speedshift transmission and offer all-wheel drive. AC also reports that a nine-speed Speedshift is in the works.
