2013 Mercedes-Benz SL65 AMG - Mercedes-Benz is wasting no time showing off the full range of its all-new SL-Class. On the heels of the SL550 and SL 63 AMG is the mighty 2013 Mercedes-Benz SL65 AMG, set to debut in 2012 next month in New York International Auto Show. Benz flagship V-12-powered SL threat will be the fastest on the market when it comes once in showrooms later this year.

The SL65's secret weapon is the 6.0-liter direct-injection, twin-turbo V-12, that 621 hp and a stump-pulling 738 lbs-ft of torque, an evolution of the last-gen V-12 SL65's M275 mill produces an output of 604 hp and 738 lb-ft. AMG engineers bolted to the new turbos that provide up to 22 psi boost, new varieties and wastegate ducts, and revised cylinder heads - deemed significant enough to change the engine of the new M279 justify designation. As with most new models in the AMG lineup, the SL65 also get an ECO start / stop system.

Another important update is the 2013 SL65 the new seven-speed automatic, which has two more teeth than the gear in the previous model. Directors will have their choice of four transmission modes: Controlled Efficiency (C), Sport (S), Sport plus (S +) and Manual (M). With the boost in horsepower and a new transmission, there is a good chance that the SL65 know 60 mph faster than the claimed time of 3.9 seconds, as long as the tires grip. An AMG rear differential is equipped to help all those enormous power over to the asphalt.

Like the SL63, the SL65 is limited to 186 mph top speed. Standard brakes are 15.4-inch discs with six-piston calipers in front and 14.2-inch discs with single piston rear calipers. AMG Carbon Ceramic Brake System is a method update if you plan to take your SL65 to attack a track or two.

To complement a straight line from the SL65 AMG is the performance of the speed-sensitive electromechanical power steering and an AMG-update Active Body Control (ABC) suspension. Turn to ABC Comfort posing for Sunset Boulevard, but in the canyons, you want to call on the Sports program, which spans body damping. The electronic stability control has three modes including Sport Handling, which must ensure that the driver of the car to explore extreme handling limits before it intervenes. Finally, the SL65 all-aluminum body construction contributes to the curb weight 4299 kg - 254 kg lighter than the previous model.

Visually, the 2013 Mercedes-Benz SL65 AMG distinguishes itself from lesser SLs through some subtle changes. The front gets a widened lower bumper with horizontally-mounted LED daytime running lights and an air-gills on both sides, while the front bumper has a chrome finish. The side and consists of V-12 Biturbo badges and standard 19-inch wheels, a set of forged AMG multi-spoke wheels with 20s and 19s in the rear to the front is available as an option. Out back, a rear spoiler sits atop the trunk deck, while the square-ish quad exhaust tips give a subtle hint at the immense performance roadster. Inside the SL65 gets treated to diamond-pattern leather seats. Like the previous model, the 2013 SL65 AMG comes with a long list of niceties, including a Magic Sky Control glass roof, a AIRSCARF neck-heating system, a Bang & Olufsen sound system and heated and ventilated seats.

Pricing has not been released for the SL65 as of yet, but expect a significant jump from the SL 63 AMG. The outgoing SL65 stickered for $ 199,000, while the SL 63 is coupled with a retail price of $ 139,000 - a difference of a C63 AMG sedan, or give a few large ones. After his debut on the New York show, the SL65 will arrive in showrooms in November 2012.

AMG was a strange claim to the San Francisco debut of the all new pint-sized speedster, the SLK 55 AMG. "It may be the most efficient performance of the car is very good in the world." Huh? I like the odd statement, because if this car is actually the "most efficient performance of the car in the world," Mercedes-Benz would sure as the sun rises trumpet that fact until the cows believed it. But what if the SLK 55 AMG sports car is really the most efficient of all? Well, good job, AMG. Only a few years ago, such a statement is laughable at a press briefing AMG. Think of the horsepower wars? The 6200-plus cubic inch engines goosed within an inch of thermal meltdown? These days, however, we are plausible. With a new corporate focus on reducing CO2 emissions 40 percent by 2015, it very well might even be true.

With that out of the way, meet the newest baby roadster sports an AMG badge - the most powerful ever (and I will argue best looking) SLK 55. While there are other bits and pieces that an AMG, at the end of all the noise (! And the 44-page press release), Mercedes-Benz in-house tuning arm is really all about one thing: big engine pumps out big band -shredding power numbers. The new SLK 55 is no exception, albeit a little different. Under the long hood is a special version of the AMG 5.5-liter V-8 (internal code name: M157). Only thing is, the two turbochargers and intercoolers are removed "packaging reasons." In their place? Nada. But do not worry, as the new (and newly baptized) M152 engine puts 422 horsepower and a fairly healthy 398 lb-ft of torque.

Think of the power figures for a moment. The outgoing, but still available in the C63 AMG (SLS Gullwing and supermodel) M156 6.2-liter V-8 cranks out 451 horsepower and 443 lb-ft of torque. The new engine will lose seven tenths of a liter in displacement, but the most important metric horsepower per liter, actually increases (by about 73 hp per liter to 77). For those keeping track, the torque per liter rate also increases, from 71 to 72 lb-ft. However, compared to the old 355 hp SLK 55, the new man is a monster. Perhaps even more important to roadster fans is that since the turbos are picked, the SLK 55 AMG sounds better than the other equipped with the M157 mill. You can actually hear the exhaust, and a lot of good back lip. Especially with the top removed and stored and the new sport exhaust burbling / screeching away.

And should you choose to fold and let the metal roof, you can breathe easier knowing that the new car puts 30 percent less CO2 than the previous version. It's also much more efficient in terms of miles per gallon, and to achieve that feat, AMG had the car put his full bag of tricks fuel-sipping. First and foremost is a smooth cylinder deactivation system that is (almost) completely unnoticeable. If you really go out of your way to feel and listen to it, you'll discover a slight (and I mean slight) tremble when the other four cylinders fire and the engine is running again in a good V-8. But in reality, the reactivation feels like a small bump in the road. The M152 also employees under high pressure direct injection (2900 psi), a high compression ration of 12.6:1, and start / stop technology. Now you have the AMG DRIVE selector in C (or Eco) mode to take advantage of both the start / stop and leave the cylinder off. And most of the time, most people probably do just that. The end result will net you about 28 mpg combined. Better yet, the car feels mighty fast, especially with the top down.

Should you choose to set the knob turn right and good things happen when the fast-ish seven-speed switching slides in Sport mode. Shifts are not only faster, but under aggressive braking transfer fires a number of beautiful downshifts. Hold the knob and you get full manual mode where you find the Mercedes gearbox almost - but not quite - as good as a similar double clutch. There is also a new torque-vectoring braking and understeer that the brakes on the rear right individual detects counteract the bad behavior. Fortunately for the driver, the SLK 55 is not too much understeer to start, so you probably will not notice that last feature to activate. I've shown a few times, and while it works, I still do not like the idea of using brakes to go faster. It's more a philosophical problem than a real one. The cars I drove were equipped with optional AMG package handling that stiffer a stiffer suspension setup, a locking rear differential, upgraded brakes and features. The result of all this new technology in the treatment is good.

Description of a beautiful twisted road near Santa Cruz, I was overwhelmed by the large bore unmistakable growl of a full-blown SLS AMG. Behind me in a white SLS Roadster were some PR peeps of MB. And when I say behind me, I mean I could hear their stereo braking zones (they were blasting Donna Summers, if you're interested). And for 30 miles, the two cars had. They had more power, but I learned to drive in California twisted canyons, so the two cars seemed well matched. I had to drive hard, but I managed to stay in front of the car much faster, especially if the road more and more complicated. The rapid run showed me the new SLK 55 AMG can handle well, even with a drop top. Hood and other typical convertible shake bad habits are minimized, so admirable. In fact, a much more talented than I was reporter to me that the new SLK 55 is a great drift machine in the paddock at Laguna Seca. Many of our German friends' grief. At the end of all this, the SLK 55 AMG is just definitely fun to drive. An important feature for people who are in the market for a small, fast and environmentally friendly roadster with almost no luggage she will likely return at least $ 75,000 - but many of them there are.
