Mercedes releases 6x6 G63 AMG specs and pics [w/video]

Mercedes-Benz has finally dropped full details on its insane G63 AMG 6x6. The machine puts 544 horsepower to all six wheels thanks to a twin-turbocharged 5.5-liter V8. A seven-speed gearbox shuttles power to the ground via three sets of portal axles, which helps give this machine a full 15.75 inches of ground clearance. By comparison, the standard G63 AMG sits with just 8.27 inches of ground clearance. The extra lift allows this 6x6 to ford nearly 40 inches of water and run massive 37-inch tires. All told, there are five differential locks on this thing, all controlled by a special "locking logic" that provides the best traction possible for any given situation.
The controls offer up three stages of locking, which we can only assume range from JKLOL to OMGWTF. Right now, AMG says this monstrosity is only a show vehicle, but we imagine it wouldn't take much to convince the team to whip up one of your very own. Check out our full gallery and the press release below for all the nitty gritty. While you're down there, you can also check out the video on the machine one more time.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).

Mercedes pays tribute to 1955 Mille Miglia with special-edition SL

The Mercedes-Benz SL is one of the longest-running nameplates in the business, and its history has been marked with numerous achievements. But few were as impressive as the 1955 running of the Mille Miglia, and Mercedes pays tribute to that race and the results it achieved there with this latest special-edition roadster. Called the SL Special Edition Mille Miglia 417, this roadster starts with the eight-cylinder SL550 with dynamic stability management and adaptive damping and adds on several highlights. Red trim adorns the front spoiler, the stripe across the matte carbon rear spoiler, the brake calipers and the rims of the black AMG Performance wheels. The red pieces accent the matte black paint, while the interior features AMG Line sports seats with carbon-finish leather and red trim, along with a red and black nappa leather steering wheel and carbon trim. The SL arrives 60 years after the Mille Miglia in which a 300 SL driven by American gentleman racer John Fitch - bearing the number 417 and starting at 4:17 a.m. - led a 1-2-3 class finish, landing fifth overall and leaving many purpose-built racers in the dust. The special edition is confirmed for the US, arriving this fall with pricing to be announced closer to launch. SPECIAL EDITION SL "MILLE MIGLIA 417" Exclusive SL passion February 17, 2015 - Stuttgart -- Mercedes-Benz celebrates the 60th anniversary of a memorable motor racing success with an extraordinary special model of the SL Roadster. Its name commemorates the unexpected victory of a 300 SL in the production sports cars class at the 1955 "Mille Miglia", one of the world's most challenging long-distance races. What's more: the SL Special Edition "Mille Miglia 417" provides a special experience of the unique symbiosis of maximum comfort and motor racing spirit that traditionally characterizes every SL. The Special Edition adds a distinctive note, among other things, with red exterior highlights and fine materials in the exclusively appointed interior. The Mercedes-Benz SL Roadster is more than an icon. Passion shapes its character and its charisma – in the past and today. Legendary vehicles and their stories dominate the model history. One of them is told by the SL that started the famous "Mille Miglia" in 1955 with race number 417 at 4:17 am. After 11 hours, 29 minutes and 21 seconds it had completed the race distance of 1597 kilometres on public roads from Brescia to Rome and back.
