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.

Next Mercedes E-Class to get quad-turbo inline-six, augmented reality

It's been 10 years since an inline six-cylinder engine sat up front in a Mercedes-Benz road car, but the straight-six shooter returns with the 2016 E-Class. According to a report in Car we'll see a modular family in gasoline and diesel versions, and Auto Evolution adds that the bore and stroke will be shared by both fuel types. Car says a 2.9-liter diesel variant arrives first in global markets, putting out 313 horsepower when twin-turbocharged and "over 400bhp" when fitted with two more battery-powered turbos. Auto Evolution's numbers match those and add torque figures, with 516 pound-feet for the former and 627 lb-ft for the latter - but it makes no mention of the two extra turbos. AE believes the gas versions will ring in at 367 hp and 479 lb-ft, and 435 hp and 553 lb-ft. Keep in mind that until we hear it from Stuttgart, this is all (exciting) speculation. Elsewhere in E-ville, more aluminum and that scalable MRA platform mean a weight loss of somewhere between 154 and 330 pounds compared to today's car. Seven bodystyles (including the CLS-Class) will continue to make up the range, with the coupe and convertible growing a bit to provide proper four-seater comfort. It will bear the new standard for Daimler technology, showcasing the next step in the company's Intelligent Drive with features like phone-controlled self-parking in confined spaces and augmented reality in the heads-up display.

Leaked dealer docs say Mercedes-AMG GT S to start at $129,900

The 2016 Mercedes-AMG GT exists as one of the most hotly anticipated European sports coupes to come along in quite some time. Offering some beautifully swoopy styling and a twin-turbocharged 4.0-liter V8 with 503 horsepower and 479 pound-feet of torque in S trim, there's really not much to dislike about it. However, until now, the price of this gorgeous German remained a mystery. According to a leaked letter to dealers obtained by Jalopnik, pricing for the 2016 GT S model allegedly starts at $129,900, and the coupe reportedly comes standard with a Nappa leather interior, Collision Prevention Assist Plus, Mercedes' COMAND infotainment system, Parktronic and Burmester sound system. The document also says more info about specific option pricing would be released in a few weeks. We've already compared both trims of the GT to the venerable Porsche 911 because the coupes seem like such natural competitors. Knowing the possible price adds one more factor to consider, though. In terms of performance, the GT S basically slots just below the 911 Turbo. However, if this amount is correct, then the starting cost is about $20,000 less than the turbocharged Porsche. While on paper the Mercedes lags somewhat in acceleration and power, it also arguably offers buyers a bit more style. This is definitely turning out to be an interesting fight between these two Germans. Related Video:
