FERRARI F12 BERLINETA vs MERCEDES BENZ SLS AMG BLACK SERIES


        FERRARI F12 BERLINETA
The Ferrari F12berlinettais a mid-front-engined coupe that is more expensive and more powerful than any road-going member of the Prancing Horse's lineup save for the mighty, limited-edition LaFerrari.
Bucking the industry's downsizing trend, the F12berlinetta uses a naturally-aspirated 6.3-liter V12 engine that churns out 730 horsepower and 509 lb-ft. of torque. Linked to a seven-speed dual-clutch gearbox, the mill sends the F12 from zero to 60 mph in 3.1 seconds, from zero to 124 mph in 8.5 seconds and on to a top speed of 211 mph
The F12berlinetta returns 12 mpg in the city and 16 mpg on the highway when driven conservatively. The aforementioned statistics are evidently far below the industry average but they make the F12 one of the most fuel-efficient cars in its segment.
Huge carbon ceramic brakes on all four corners keep the extra power in check, while vanes that open automatically at high speeds help route cool air to the rotors and the calipers. The electronic driving aids include a high-performance ABS system, Ferrari's F1-Trac traction control, ESP Premium and an electronic differential.
The F12's chassis and body are crafted out of 12 different kinds of alloy in order to reduce weight and increase structural rigidity. Thanks to careful packaging, 54-percent of the coupe's 3,362-pound weight lies on the rear axle.
Aerodynamics First
Penned jointly by Ferrari's in-house styling department and Pininfarina, the F12berlinetta's aggressive design is noticeably inspired by the four-seater FF. Its front end is characterized by a long, sculpted hood, sharp headlamps and Ferrari's signature egg-crate grille. Vents on the hood reduce drag by routing air away from the top part of the car.
Heavily-sculpted flanks and a functional air diffuser integrated into the rear bumper further enable the F12 to cheat the wind, while round tail lamps pushed to the extremities of the rear end emphasize the car's width.
Driver-Focused Cockpit
The F12berlinetta offers a premium, high-tech cockpit with numerous aircraft-inspired touches. The two passengers are treated to round air vents made with carbon fiber and aluminum, exquisite Frau leather on the seats, the center console and the dashboard as well carbon fiber trim on the dash.
The driver sits in front of a three-spoke, flat-bottomed steering wheel that houses every major command including switches for the turn signals, the headlights and the windshield wipers, a knob used to select a driving mode and a button that turns the engine on and off. The climate controls are conveniently located on the dashboard.
The instrument cluster consists of a large tachometer mounted front and center. It is flanked by a speedometer, a fuel gauge and gauges for the oil and water temperature.
Interestingly, a small, discreet screen mounted above the glovebox gives the passenger basic information such as the engine's rpms and the speed the car is traveling at.

  MERCEDES BENZ SLS AMG BLACK
It wasn’t exactly a well-kept secret, Mercedes-Benz’s plan to come up with an über bad-ass version of the SLS to maintain the momentum and give the competition something to chew on. We spied the prototypes and we received hints from AMG chief Ola Källenius himself. Despite all the foreshadowing, though, the aggressiveness of the 2014 Mercedes-Benz SLS AMG Black Series leaves us stunned. The gaping intakes, the spoilers, and the carbon-fiber trim of Affalterbach’s latest pride and joy makes the SLS AMG GT look pretty vanilla—only by comparison, of course.
The Black Series models are rarer, quicker, much louder, and beastlier than the standard models on which they’re based. To top the regular-grade SLS, Källenius's troops laid their hands on almost every facet of the car. The 6.2-liter V-8 engine now makes 622 hp, a healthy dose of burly over the standard SLS GT’s 583. This bump in power is achieved through a derestricted air intake, a revised valvetrain, an increased compression ratio, and a redline elevated from 7200 rpm to 8000.
Interestingly, peak torque has dropped from 479 lb-ft to 468. And while the 0-to-60-mph sprint is quicker at 3.5 seconds versus the GT’s 3.8-second time—we think those are awfully conservative estimates considering the last standard-spec SLS we tested did the deed in 3.5 seconds when Benz predicted 3.6—top speed actually drops from a governed 197 mph to 196. Go figure. It would appear as though the extra power can’t conquer the aerodynamics.
To keep the engine reliable under extreme loads, the crankshaft and its bearings are modified, a new oil pump is installed, and the connecting-rod connections are altered. The structure housing the higher-power engine is supported by a gas-filled strut brace to keep unwanted movement to a minimum. For the three people who believed the regular SLS sounds too wimpy: A much louder titanium exhaust system has been fitted to the Black—it also happens to be nearly 29 pounds lighter than the standard car’s exhaust. The seven-speed dual-clutch automatic has been mounted a touch lower than in the SLS GT, and it features quicker shift programs as well. And your grandmother will appreciate the fact that the throttle blips on downshifts are “more pronounced and striking than ever.”
Grip is improved by a new, electronically controlled locking rear differential, and the control-arm suspension has been significantly altered. The coil-overs can be individually adjusted, and the SLS AMG Black Series sits on 275/35-19 tires up front and 325/30-20 tires in the rear. The same carbon-ceramic brakes available on the SLS GT come standard on the Black.
Visually, the aforementioned air intakes and carbon-fiber trim make an immediate impression, and that’s because the SLS Black’s looks are inspired by those of the SLS AMG GT3 race car. The front end features aero flics bookending the lower fascia, a front splitter, and a large heat extractor in the center of the hood that also increases downforce at the front axle. A fixed rear spoiler with a Gurney flap resides on the decklid when the car is optioned with the Aerodynamics package. The body is significantly wider, and four exhaust finishers replace the dual outlets of the SLS GT. The Solar Beam exterior finish is unique to the SLS Black Series, but otherwise the car can be painted the same color as any other gullwing Benz.
Depending on your priorities—speed or comfort—the interior has been either upgraded or downgraded. The COMAND telematics system is thrown out, saving 13 pounds from the interior, but it remains available as an option. But in stripped form, the SLS AMG Black series manages to drop an impressive 154 pounds when compared to the plain-old SLS GT. The remainder of the interior is swathed in faux suede, Designo leather, carbon-trim, and red accent pieces.
The SLS AMG Black Series ought to have AMG aficionados tripping over themselves to get one of the limited-production Blacks when the car goes on sale next summer, even though we expect prices to have a considerable markup from the base car’s $192,175 sticker.
