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.

Mercedes-Benz previews its curvy sports-car and design future

Suggesting creases are passe for automotive design, Mercedes showed off ideas for its future styling directions this week at a forum in Germany, including previews of upcoming sports cars and sedans. We see images of a curvy sports car study (the silver car) with huge wheel arches flared out almost like pontoons. There's also what appears to be a rear-engine hypercar (white car); we've been reading reports about it for months. Additionally, there's a red sporty saloon, as Mercedes calls it, also among the photos. It features prominent rounded fenders and a bold horizontal grille. Mercedes also previewed its upcoming A-Class, in what it calls the Aesthetics A sculpture, which looks like a car covered in a red sheet. Though Mercedes says this is its next step to a purer design, creases and strong lines are still evident on the sides. Related Video:

Aston Martin and Mercedes-AMG bicycles: Luxury branding has no bounds

Luxury automobile companies are never quite satisfied with building high-end cars. They often stray into other types of branded merchandise that can have little to do with cars, such as the BMW Active line of clothing and accessories. Splitting the difference between branded merchandise and actual vehicles are these two limited-production bicycles from Mercedes and Aston Martin. The bike above is a collaboration between Mercedes-AMG and German bicycle brand Rotwild, a builder that has been around since 1996, according to the company's website. The bicycle in question is the R.S2 "Beast of the Green Hell." It's inspired by the Mercedes-AMG GT R sports car that was promoted with the same nickname. It uses a carbon frame and wheels, as well as disc brakes. It's also painted in green and black to match the Green Hell Magno color available on the GT R. Only 50 of them will be built, and each will carry a pricetag of over ˆ7,000, or nearly $8,300 at current exchange rates, including tax. View 4 Photos The second bicycle is from Aston Martin and another German bicycle company, this one called Storck Bicycles. This bike company has also only been around since 1995. The bike is called the Fascenario.3 Aston Martin Edition, and it will be a bit less rare than the Mercedes bicycle, with 107 total units. It's still a cool vehicle, though, featuring a carbon frame and wireless shifters. In total it weighs 13 pounds. It does lack the disc brakes of the Mercedes bicycle, though. Pricing hasn't been announced for the Aston Martin bike, but don't expect it to be cheap.
