2015 Mercedes-AMG C63 S First Drive [w/video]

As I mashed the throttle heading into the back straight of a nearly three-mile-long race track, I couldn't help but center my mind on two ostensibly disparate subjects: physics and pistons. If the heart of an automobile is its engine, the heart of the engine are its rotating bits – the crankshaft, pistons and the block they're nested inside. It seems fitting, then, that the internals of the twin-turbocharged 4.0-liter V8 typify the brand-new 2015 Mercedes-AMG C63 sedan I found myself piloting in Portugal. Whereas the last C-Class AMG availed itself of a brute of an engine, employing 6.2 liters of displacement to make its 451 horsepower the old fashioned way, the latest AMG's V8 engine has been downsized radically. I had the opportunity earlier in the day to actually hold the pistons of the new 4.0 Biturbo V8 in my hands, alongside those of the outgoing 6.2. The difference in size is staggering, the new lumps looking downright picayune in comparison to the latter. These eight seemingly diminutive pistons turn combustion into crankshaft-spinning power inside a block that is smaller, lighter and more compact than I'd have thought possible, considering the prodigious output the engine spits out. I had gone into this assignment expecting to pen an ode to lost love; a sonnet of sorrow bemoaning the switch from massive cylinders to wheezing power adders. But I was wrong. In fact, the report that follows may indeed read a little like a love song, except it will heap praise not on what used to be, but instead on what is now possible. The new heart of AMG more than makes up for its reduction in size by relying on turbochargers and smart engineering to turn just 4.0 liters into 469 horsepower and 479 pound-feet of torque starting at just 1,750 rpm, or as much as 503 ponies and 516 lb-ft in uprated S guise. Foot to the floor, eyes focused on the turn ahead, a hard right-hander named Primeira that requires hard braking and quick reflexes, I had a fleeting moment of clarity: These are some hard-working pistons. A few days on the street and track in and around Faro, Portugal, has convinced me that the new Mercedes-AMG C63 is a better car in any meaningful measurement than it was before. And I'll go one step further. Not only is this the best C-Class AMG ever, it's also my new favorite in the hotly contested segment that includes such knee-benders as the BMW M3 and M4.

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.

Autoblog fan favorite car ads from Super Bowl XLIX

Super Bowl XLIX is in the books, and the New England Patriots emerged victorious. Of course, if you're like us, the big game wasn't so much about the battle between the east coast and west, so much as a fight between the world's automotive advertisers. We collected and collated all of last night's new ads and put them together for you to vote on. And yes, we're limiting this year's contest to last night's new features. That's why you aren't seeing Dodge's epic Wisdom among our collection of commercials, and it's a similar story with Chevrolet's Truck Guy Focus Group series, which highlights the new Colorado. You can still vote for your favorites. We won't be closing the voting on our Super Bowl page, so while the winners and losers are correct as of this writing, it's entirely possible that there could be some changes in the rankings as time goes on. So, without any further ado, here are the winning ads based on your voting. Nissan: With Dad Fiat: Ready For Action Jeep: Beautiful Lands BMW: Newfangled Idea Mercedes-Benz: Fable NASCAR: America Start Your Engines As for those ads that failed to impact you, loyal readers, Toyota was the absolute, undisputed loser. The Japanese brand ran four ads in total – two for Toyota and two for Lexus – and all of them have negative tallies as of this writing. Lexus' Make Some Noise and Lets Play and Toyota's One Bold Choice and My Bold Dad both had very weak showings among the commercials that aired, although they weren't alone. Neither Mazda nor Kia scored particularly well, despite featuring celebrity magic act Penn and Teller and former James Bond, Pierce Brosnan, respectively. Chevrolet was the winner of the losers, as of our writing, recording the fewest downvotes for its audience-punking The Big Game ad. If you want to take a second look at the losing ads, you can head back to our Super Bowl page for the complete collection. But for now, head into Comments and let us know what you think of the results.
