2016 Mercedes-Benz C450 AMG Sport First Drive

A. M. G. Those three letters carry a lot of weight, especially to those who firmly believe that AMG is the hallowed performance pinnacle of the Mercedes-Benz brand. Those purists probably lifted an eyebrow at the front-drive platforms behind the CLA45 AMG and GLA45 AMG, and virtually every AMG-branded SUV that has hailed from the tuner-focused nameplate. But they might want to consider a second look at the 2016 Mercedes-Benz C450 AMG Sport. No, it's not a full-blown, fire-breathing AMG like the C63, and it doesn't get the newfangled "Mercedes-AMG" nomenclature. But after spending some seat time in the C450 AMG Sport, there's a decent chance you'll be quite alright with that. Inside and out, the C450 bears a strong visual resemblance to the mean looking, V8-powered, 469-horsepower C63 and its even fiercer, 503-hp, C63 S variant. The C-Class cockpit feels a bit snugger than you might expect considering its exterior proportions, particularly from the passenger seat. On the other hand, the new C-Class is also quite a bit more nicely appointed than its predecessor, which has inspired more than a few comparisons to the super posh S-Class. As for the C450 AMG, its more purposeful design cues and sportier details lend it a buttoned-down, modern feel. The biggest differentiator between the C and CLA class, however, is the rear of the cabin: the C's back seats are considerably roomier than the entry-level CLA's posterior perches. In place of V8 power, the modest 450 AMG packs a more reasonably endowed twin-turbocharged, 3.0-liter V6 that pushes 362 hp and 384 lb-ft of torque through a 7G-Tronic Plus automatic gearbox (in place of the the C63's dual-clutch seven-speed). Power is routed through all four wheels with a 66-percent rear, 33-percent front torque split. For some numerical context, the C450 AMG exceeds the C400 by 33 hp and the C300 by 121 hp, while it lags behind the C63 by a rather significant 107 hp. Crucially, the six-banger helps shed between 231 and 242 pounds compared the C63 models – this, despite a heavier all-wheel-drive arrangement, as opposed to the C63's rear-drive configuration. The C450 AMG shares a few pieces of hardware with its big brother AMG sibling, including the front axle, electromechanical steering, and upgraded brake setup (though you can't get carbon ceramic stoppers like you can in the C63 S).

New Mercedes E-Class nearly exposed, may be Maybach

The all-new Mercedes-Benz E-Class is marching closer and closer to production, with a new round of spy photos giving us our best look yet at the S-Class-inspired looks of the German brand's executive luxury car. There really is very little camouflage this time around – what's there looks more like the kind of plastic wrapping you'd see on a freshly imported vehicle at the port. In front, we can see the new E will wear similar LED accents to the S- and C-Class. The E-Class' big and little brothers also inspired the tail of the new model, where we can see slightly disguised, vertically oriented LED taillights. Prominent, enclosed exhausts are very similar to what we saw in our spy shots of the Mercedes-Maybach E-Class. Aside from the exhausts, this particular car also wears the same blingy wheels as the range-topping tester we spied last August. The thick-rimmed, multi-spoke design isn't the only giveaway to this car's luxurious intentions, though. Our last Maybach sighting showed a car completely covered in camo, making it difficult to tell just how large the rear doors are relative to the car we're seeing today. Instead of the doors, though, we suggest you look at the windows. Like the August spy photos, this prototype features tinted rear glass, which could perhaps indicate that we're looking at yet another example the second Mercedes-Maybach model. So is this yet another Maybach E-Class? We're leaning towards yes. The size of the back doors – and the rear quarter window, in particular – is close enough to what we saw last month, and the presence of tinted glass, the same exhausts, and the same wheels can't be discounted either.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
