(twin-turbocharged) engine develops a maximum output of 463 kW (630 hp) and maximum torque of 1000 newton metres. The result: exceptional performance, impressive power delivery and effortlessly superior dynamics. As with the Mercedes-AMG SLS AMG super sports car, the use of an all-aluminium bodyshell results in a drastic reduction in weight. The new SL65 AMG is some 170 kilograms lighter than before. The expressive front section is dominated by the new “twin blade” radiator grille and the front apron’s lower cross strut in high-sheen chrome.

Mercedes-AMG is launching itself into the 2012 roadster season with a vengeance. Arriving in U.S. dealerships in November, the new MY2013 Mercedes-Benz SL65 AMG V12 Roadster is making its world debut at the 2012 New York Auto Show. The AMG 6.0-liter V12 biturbo engine generates a peak output of 621 hp and a maximum torque of 738 lb-ft. The use of an all-aluminum body-in-white delivers a drastic weight reduction as the MY13 SL65 AMG is 254 pounds lighter than before. The distinctive front end is dominated by the new “twin-blade” grille with two blade-shaped fins and the lower horizontal bar in the front skirt in high-gloss chrome.

The SL65 AMG joins the SL550 roadster and the SL63 AMG roadster. The SL550 has a starting retail price of $106,375 and arrives in U.S. Mercedes-Benz dealerships in May. The SL63 AMG arrives in July.

“The combination of exclusive V12 dynamics and cultivated roadster pleasure was already unique in the previous model. We are certain that, with the new SL65 AMG, we have developed a stunning high-performance automobile beyond compare for a small, but loyal fan base,” says Ola Källenius, CEO of Mercedes-AMG GmbH.

The intelligent lightweight design of the bodyshell also contributes to the reduction of fuel consumption. A key element in the improved fuel efficiency is the result of the AMG SPEEDSHIFT PLUS 7-Speed transmission, the ECO stop/start function, and improvements to the internal efficiency of the engine and alternator management. Despite a considerable improvement in fuel economy, the peak output of the AMG 6.0-liter V12 biturbo engine is up from 604 hp to 621 hp. The maximum torque stands at a mighty 738 lb-ft.

This unparalleled output provides amazing propulsion for the new SL65 AMG – acceleration from 0 to 60 mph takes 3.9 seconds. Top speed in the U.S. market stands at 186 mph. The key attributes of the AMG biturbo twelve-cylinder include its heart stopping acceleration, and seamless power delivery combined with a distinctive AMG V12 soundtrack. In short, the SL65 AMG captures the imagination with its refined, stylish performance.

2013 Mercedes-Benz SL65 AMG ROADSTER

2013 Mercedes-Benz SL65 AMG – Grease n Gasoline

AMG 6.0-liter V12 biturbo engine with new technology

The AMG 6.0-liter V12 biturbo engine (M 279) is based on the previous M 275 unit and has been extensively developed for its application in the new SL65 AMG. New turbochargers with an enlarged spiral cross-section, new manifolds and wastegate channels optimized for airflow deliver an additional 17 hp. The multi-spark ignition with twelve twin ignition coils not only makes for smoother running, but also works together with a new, more powerful engine management and optimized cylinder heads to provide even more effective combustion. The outcome is fewer exhaust emissions, which is also in large part due to the optimized catalytic converter system.

The redeveloped AMG sport exhaust system incorporates a modified pipe layout for improved flow coupled with a weight reduction of seven pounds resulting from reduced wall thicknesses.

And it is not just the inner attributes of the AMG 6.0-liter V12 biturbo engine that are stunning – the engine also looks inspiring. The carbon-fiber and aluminum engine cover further underscores the exceptional nature of the powerful twelve-cylinder that lies beneath.

AMG SPEEDSHIFT PLUS 7-Speed transmission

For the first time, AMG is combining the 6.0-liter V12 biturbo engine with the AMG SPEEDSHIFT PLUS 7-Speed transmission. The wide ratio spread of the seven-speed automatic transmission delivers significantly lower revving and helps in the reduction of fuel consumption. A new fuel-economy torque converter, reduced-friction bearings and transmission oil thermal management further increase the efficiency of transferring power to the wheels.

The AMG SPEEDSHIFT PLUS 7-Speed transmission features four individual drive programs that can be selected at the touch of a button on the center console – Controlled Efficiency (C), Sport (S), Sport plus (S+) and Manual (M). The ECO stop/start function is always active in C mode. For the greatest sense of involvement and dynamics, there is the automatic double-declutch function for downshifting, as well as brief and precisely defined retardation of ignition and injection during upshifting under full load. The latter also reduces shift times.

Intelligent lightweight design featuring all-aluminum body-in-white and carbon

2013 Mercedes-Benz SL65 AMG – Grease n Gasoline

Compared to the steel construction of the previous model, the all-aluminum body-in-white of the new SL65 AMG delivers weight savings, as well as superior stiffness, safety and comfort. Intelligent lightweight design also means optimizing components for their specific application. For instance, an array of different aluminum processes come into play – components are made using gravity die casting or vacuum pressure casting, worked into extruded profile or used as aluminum sheet with varying wall thicknesses. The results are a high degree of stiffness and safety and improved vibration characteristics. Engineers made use of the even lighter magnesium for part of the cover behind the fuel tank. High-strength steel tubes are integrated into the A-pillars for reasons of safety.

Further weight reduction comes courtesy of the rear decklid. The internal frame is made from carbon composite material. The plastic exterior shell is then fastened to the extremely stiff carbon component with adhesive. The result is a weight saving of eleven pounds compared with a conventional rear lid. The innovative solution is being used initially in AMG’s SL models. The outcome of the many lightweight design innovations is that the curb weight of 4,299 pounds for the new SL65 AMG is 254 pounds less than that of the previous model.

AMG sport suspension based on Active Body Control

When it comes to the chassis, Mercedes-AMG is focused on lightweight engineering. The four-link front suspension incorporates steering knuckles and control arms in aluminum, which also features in almost all suspension parts on the multilink rear axle. Agility is not the only aspect to benefit from the reduction of unsprung masses; the response characteristics of the spring-and-damper units are also improved. Like the previous model, the new SL65 AMG is fitted with the ABC active suspension system as standard. The AMG sports suspension based on Active Body Control is a further developed version of the setup in the SL63 AMG with the eight-cylinder engine, tuned specifically for this application.

Handling and performance were the top priorities during conception, development and testing. Two chassis settings are available for selection at the touch of a button – a very sporty setting with reduced roll rate and tighter body damping (“Sport”) and a program offering a high degree of long-distance comfort (“Comfort”). More negative camber on both axles, plus completely re-engineered elastokinematics deliver increased agility and higher cornering speeds.

New electromechanical AMG speed-sensitive steering

Combined with the all-new, electromechanical AMG speed-sensitive sports steering, the V12 top-of-the-range model offers a stunning ride with excellent dynamics and very clear feedback at the edge of the performance envelope. The steering ratio is constant and direct, while the power assistance adjusts in line with the chassis mode. Standard equipment also includes the 3-stage ESP®, a specialty exclusive to AMG with “SPORT Handling” mode for enthusiastic drivers. The enormous engine power is harnessed with the aid of AMG rear-axle locking differential, which is also standard equipment.

Top deceleration figures, perfect modulation and excellent stability – all standard features of an AMG high-performance brake system. The same applies to the all-new brakes on the SL65 AMG – on the front axle are 15.4 x 1.4 in. compound discs with six-piston fixed calipers, while the rear axle boasts 14.2 x 1.0 in. integral discs with single-piston floating calipers. An electric parking brake is standard equipment. The even more powerful and weight-optimized AMG carbon ceramic brake system familiar from the SLS AMG is available as optional equipment.

New AMG “face” with two blade-like fins

The SL65 AMG is clearly recognizable as a stylish and exclusive high-performance roadster not just technically, but also visually. The SL65 AMG is presented for the first time with the new AMG “face”. The two dominant visual elements – the grille and the lower air inlet – remain, but have been reinterpreted to give them a more distinctively dynamic and premium look. The central styling feature is the new twin-blade grille finished in high-gloss chrome. The Mercedes star is mounted on two blade-like fins with aerofoil profiles. The stronger arrow-form of the grille optimizes the vehicle’s longitudinal proportions, adding even more visual emphasis to the aerodynamic, minimalist design.

The stylized “A” that is a hallmark of AMG vehicles is retained beneath the twin-blade grille. Along the lower edge of the air intake is a slit beneath a fine black fin for optimum airflow to the cooling modules – a perfect combination of design and high technology. The lower horizontal bar on the front skirt is finished in high-gloss chrome and is lent significant visual depth by the slit above it, creating a premium visual accent. The twin-blade grille and lower horizontal element are two corresponding design features that emphasize the new AMG brand “face” – this look will be further developed in forthcoming AMG models, increasing even more the visual recognition of the AMG performance brand.

2013 Mercedes-Benz SL65 AMG – Grease n Gasoline

The top-of-the-range model is distinguished from the SL63 AMG by carefully placed applications in high-gloss chrome – as well as the twin-blade grille and the lower horizontal bar on the AMG front skirt, the bezels in the AMG-specific LED daytime running lights, the side fins on the fenders and fins on the hood all have the same surface finish. The characteristic AMG styling of the SL65 AMG also includes the front skirt with large openings for cooling the engine oil, water, charge air and transmission oil, the specially designed sill panels, the AMG spoiler lip and the rear skirt with a diffuser visual and body-color inlay.

Typical V12 features are not only the two chromed, standalone dual end pipes of the AMG sports exhaust, but also the V12 BITURBO lettering on the fenders and the titanium grey painted and polished 5-spoke AMG alloy wheels with 255/35 R 19 tires on the front and 285/30 R 19 on the rear. Optional AMG forged alloy multi-spoke wheels from the AMG Performance Studio with 255/35 R 19 tires at the front and 285/30 R 20 at the rear reduce unsprung mass are also available. The forged wheels are also available in matte black with polished outer rims.

Retractable hard-top with MAGIC SKY CONTROL

The sixth generation of the SL offers a space-saving electro-hydraulic retractable hard-top that converts the SL65 AMG from a roadster to a coupe in less than 20 seconds. In contrast to the previous model, the new SL comes with the unique MAGIC SKY CONTROL. Its transparency can be switched from light to dark at the touch of a button.

Interior – pleasure for all the senses

Inside, the SL65 AMG is distinguished from its eight-cylinder sibling by highly exclusive design and equipment features. One particular eye-catcher is the electrically adjustable AMG sports seats with one or two-color upholstery in exclusive leather featuring AMG-specific V12 diamond stitching. This distinctive upholstery also appears on the center door panels. The AMG logo embossed on the seat backs is a standard feature, as are AIRSCARF neck-level heating, the multi-contour function, seat memory and seat ventilation. The designo headliner in leather featuring AMG V12 diamond stitching provides a perfect finish that is both visual and tactile.

The cockpit design is reminiscent of the SLS AMG – the four air vents in jet-engine style, the E-SELECT gear lever and the AMG DRIVE UNIT are all evocative of the super sports car. The selection of exquisite materials and high quality of workmanship in the interior of the SL65 AMG creates a truly sensual masterpiece. This is underscored by the AMG trim elements in carbon, the analog clock in IWC design, the chromed and white illuminated AMG entry trim and the AMG performance steering wheel incorporating an AMG logo in the lower metal spoke. A 225 mph scale in the AMG instrument panel and the AMG start-up display with exclusive AMG V12 BITURBO animation hints at the phenomenal dynamics of the SL65 AMG.

The twelve-cylinder roadster comes with an extensive list of standard equipment:

One of the world’s safest roadsters

Thanks to its collision-optimized aluminum structure, standard PRE-SAFE® System and assistance systems on a par with the S-Class, the SL is one of the safest roadsters in the world. The stiff aluminum body-in-white forms a stable occupant cell and provides precisely defined crumple zones front and rear. In the event of a rollover, the A-pillars in a steel/aluminum material mix and two automatic pop-up rollover bars offer outstanding protection for the passenger area.

The restraint systems that include two-phase driver and passenger airbags have been further developed. Head/thorax side impact airbags in the backrests protect the upper body in the event of a side impact. The NECK-PRO Active Head Restraints designed by Mercedes-Benz also feature as standard equipment. Pedestrian protection is enhanced by large surface-area, compliant impact surfaces.

Last week’s sneak peek at Ferrari’s replacement for the 599 GTO didn’t spoil all the surprises. Here are the first official pics of what Ferrari will call the F12 Berlinetta, a V-12 powered coupe that can hit 60 mph in 3.1 seconds and ranks as the fastest road-going Ferrari built to date.

Using tricks learned from its Formula 1 cars, Ferrari claims the F12 burns less fuel and goes faster than its predecessors thanks to combination of high-tech machinery, wickedly complex weight loss schemes and a bit of black magic aerodynamics. The 6.3-liter V-12 shared with the Ferrari FF has been boosted to 730 hp and 509 ft-lbs of torque, yet can get nearly 19 mpg under Euro testing with an optional stop-start system. That power goes through a seven-speed gearbox and electric differential, both resized to shrink the car’s footprint. That gap you see at the top of the hood is what Ferrari calls an “aero bridge” — a tunnel that shunts air out the vents behind the front wheel arches, helping reduce the car’s drag.

Ferrari F12 Berlinetta

Without any doubt, the most popular and interesting car of this year’s edition of the Geneva Motor Show is the all-new Ferrari F12 Berlinetta, a car for which about 360 people made a deposit before it was officially unveiled at the event in Switzerland. This number comes from Amedeo Felisa who is the company’s CEO.

Ferrari F12 Berlinetta

Before the car went live in Geneva it was shown during an event for customer previews which lasted about a week. During this time, about 450 people had the possibility to see the car and 80% of them decided to put an order on the F12 Berlinetta, according to Felisa.

Ferrari F12 Berlinetta

The new F12 Berlinetta is the most powerful road car that Ferrari has ever made as it is powered by an impressive V12 6.3-liter engine that pumps out no less than 730 hp. Even though many people though that V12 engines will soon be discontinued, it seems that Ferrari doesn’t think this way and for the successor of the Enzo which is scheduled to come out towards the end of this year, another V12 engine will be used.

Ferrari F12 Berlinetta

Thanks to this powerful engine, the F12 Berlinetta is capable of doing the 0-62 mph sprint in only 3.1 seconds while to get to 124 mph from start it needs 8.5 seconds. That V12 engine has a maximum torque of 509 lb.-ft and 80% of that torque is available at just 2500 rpm. This V12 normally-aspirated engine revs up to an impressive 8700 rpm.

Ferrari F12 Berlinetta

The successor of the 599 was initially supposed to be called the 620GT but this new name that it got reminds of some classic cars Ferrari has made in its glorious history, like the 250 GT Berlinetta. The Italian automaker has said that the car managed to do a lap of the company’s Fiorano test track in 1 minute and 23 seconds, making it the fastest Ferrari that was on that circuit. The company says that the F12 Berlinetta is capable of reaching a top speed of more than 211 mph.

Ferrari F12 Berlinetta

This V12 engine offers 116 hp / liter and it is based on the power unit found in the FF, a 6262cc 65-degree V12 unit. However, the new iteration of this engine is 80 hp and 5 lb.-ft more powerful than what the FF has to offer and it’s also more powerful than the 599 model it replaces in the company’s lineup.

Ferrari F12 Berlinetta

Even though this new V12 engine is considerably more powerful, Ferrari’s engineers have managed to lower not only the fuel consumption levels but also the emissions of CO2. While the 599 offer 15.8 mpg UK in the combined cycle, the new F12 Berlinetta can return 18.8 mpg. In addition, the 415 g/km CO2 emissions of the 599 have been reduced to 350 g/km in the new model. These figures are available if the car is fitted with the stop/start system which is an optional feature.

Ferrari F12 Berlinetta

Ferrari’s new model is 4618 mm long, 1273 mm high and 1942 mm wide, making it 47 mm shorter, 63 mm lower and 20 mm narrower than the outgoing 599. In addition, compared to its predecessor, the wheelbase is now 30 mm shorter, measuring 2720 mm.

Ferrari F12 Berlinetta

The most important modifications can be found at the back where the dual clutch F1-style gearbox and the rear suspension have been repacked in order to lower the volume at the rear. In addition, the dashboard, seats and engine have been lowered, managing to offer a lower center of gravity in comparison to the previous 599 model. The outgoing model had a weight distribution of 47/53 while the F12 Berlinetta sports an “ideal” weight distribution of 46/54 front/rear.

Ferrari F12 Berlinetta

The car has an aluminum spaceframe chassis and bodyshell which have been developed especially for the new model, boasting 12 different types of alloys. The Italian carmaker has said that compared to the 599, the new F12 Berlinetta offers a 20% structural increase and weighs 70kg less than the previous model, with a curb weight of 1525 kg.

Ferrari F12 Berlinetta

The downforce is now 76% greater over the 599 while the drag coefficient stands at just 0.299. To achieve these more than impressive figures, the Italians implemented the Aero Bridge system which is capable of channeling air from the side hood air intakes via the wheel arches and after that it spits the air out via the car’s sculpted deep swage lines located in the F12’s side doors, managing to improve the control of turbulent airflow and also reduce the drag. Aside from this, the car also has Active Brake Cooling that will open the brake cooling ducts only when the temperature of the carbon ceramic brakes is high enough.

Ferrari F12 Berlinetta

As you would expect, the all-new Ferrari F12 Berlinetta comes with a bunch of electronic aids to help the driver, including the company’s own E-Diff, F1-Trac, ESP Premium and a high-performance ABS system. Aside from these, the car also comes with the SCM-E magnetorheological suspension system, and Ferrari says that they were also able to lower the car’s steering angles.

Ferrari F12 Berlinetta

By making the space behind the two seats accessible from the car’s hinged glass tailgate, Ferrari said that the capacity of the rear luggage has been increased but they didn’t mention an exact volume. The dashboard of the F12 Berlinetta has a lightweight construction while the interior is wrapped around in Frau leather. There are also lashings of aluminum and carbon fiber trim, along with an aeronautic field-inspired design of the air vents.

Ferrari F12 Berlinetta

If there is something that we don’t like about the Ferrari F12 Berlinetta is that Human Machine Interface which we’ve already seen on the FF and the 458, which is an interior control system that puts most of the major controls on the steering wheel making it look too crowded and difficult to access.

No word at the moment about the price tag of the Ferrari F12 Berlinetta but most likely it will cost more than 250,000 pounds. The right-handed units will arrive in the United Kingdom in the beginning of next year. We’ll let you know when Ferrari will publish the price list for the new model and also details about the car’s availability.
