Mercedes takes off the veils on the new SL which is reborn only with the AMG brand . This is a whole new project that for & ograve; does not forget the tradition of a model that & egrave; came to light, the first time, just under 70 years ago. In 1952, in fact, the brand port & ograve; the first SL makes its debut, a racing sports car suitable for road use.
Now, in 2021, the latest version of this icon of the car manufacturer, a roadster in 2 + 2 configuration equipped with a sporty character and a canvas hood that recalls the & quot; tradition & quot; of this model. The car is fully developed by Mercedes-AMG in Affalterbach. Prices for the Italian market have not yet been disclosed.
ALL NEW PLATFORM 
For this car, AMG has created a completely new aluminum platform . Compared to the previous series, the rigidity & agrave; torsional & egrave; increased by 18% and the transversal one is; 50% higher than the gi & agrave; excellent value of AMG GT Roadster. The goal, of course, was to achieve the typical driving experience of all AMG models without compromising comfort and safety.
The new Mercedes-AMG SL it has short overhangs, long bonnet, cockpit set back with steeply sloping windshield and powerful tail. The proportions, however, are always those of the SL models. The AMG-specific radiator grille emphasizes the width of the front. The slim LED DIGITAL LIGHT headlights also contribute to giving a decisive and sporty character to the front.
Aerodynamics & egrave; been treated with extreme attention to obtain the most efficiency; high as possible. All the work done made it possible to obtain a Cx of 0.31 that & egrave; interesting for an open sports car. With the top open or closed, the character of the car and its behavior on the road remain unchanged. As proof of the attention that AMG has placed on the design of the new SL, the presence of active aerodynamics .
The AIRPANEL active air regulation system is made in two parts. The first uses vertical louvers hidden behind the lower air intake grille in the front apron. The second, on the other hand, is located behind the upper air intake grille and has horizontal blades. Normally, the slats are closed and this guarantees less aerodynamic drag. The air flow is directed towards the underbody to further reduce the front lift.
If the internal temperatures rise above a certain threshold, the louvers open (those of the second system only from 180 km/h) and allow the maximum flow of cooling air to flow towards the heat exchangers. Another active element of aerodynamics is the removable spoiler . Starting from 80 km/h, the spoiler assumes five different positions to optimize stability; or aerodynamic drag. In addition, among the options, & egrave; It is possible to have a carbon active element in the underbody that protrudes at 80 km/h by 40 mm to reduce the lift on the front axle.
19, 20 or 21-inch light alloy wheels are available, all aerodynamically optimized. Another very important element of the new SL & egrave; the canvas hood . In addition to the references with the step models, this element has a precise relevance within the project. In fact, the canvas top allowed to save 21 kg compared to the folding metal roof. The hood both opens and closes in 15 seconds up to a speed; maximum speed of 60 km/h.
Mercedes-AMG SL measures 4,705 mm length x 1,915 mm width x 1,359 mm height, with a wheelbase of 2,700 mm.
INTERIORS 
We already had an advance on how the interiors would have been; had with a series of photos that Mercedes had shared in recent times. The German brand says that the designers were inspired by the interior of the 300 SL Roadster. We find a clean and obviously very elegant design thanks to the presence of refined coatings.
There is a lot of technology thanks to the MBUX system very similar to that of the new S-Class. We have a 12.3-inch screen for instrumentation and an 11.9-inch vertical display for infotainment. Special feature, this display can be adjusted in the inclination to avoid glare from the sun when traveling with the top down. Obviously all the classic features are not lacking; of the MBUX system with the only difference that the graphics are; has been revised in parts by AMG. In addition, there are some options for use on the track.
The interiors have a 2 + 2 configuration which guarantees more; space. The rear seats can accommodate people up to 1.50 meters in height. The seats are, of course, of the sports type with integrated head restraint. The AIRSCARF is also standard. The vents integrated in the headrests emit hot air that allows the driver and front passenger to heat the neck.
ENGINES AND SAFETY
At launch, the new Mercedes-AMG SL will be; proposed with the 4.0-liter AMG twin-turbo V8 in two power levels. On the top of the range model SL 63 4MATIC + , the engine produces 430 kW (585 HP) with a torque of 800 Nm. Therefore, the performance is excellent. . Acceleration from 0 to 100 km/h takes place in just 3.6 seconds, the speed maximum & egrave; of 315 km/h . Instead, the SL 55 4MATIC + model (it will not arrive in Italy) can count on 350 kW (476 hp) with 700 Nm of torque. To go from 0 to 100 km/h it takes 3.9 seconds, while the speed; peak reaches 295 km/h.
Both powertrains are mated to an AMG 9G SPEEDSHIFT MCT automatic transmission. In the future, it will come also a Plug-in hybrid version . No further details were shared on this point. For the first time in the history of the SL, & egrave; 4MATIC + Performance AMG all-wheel drive is available, with fully variable torque distribution. A lot of care & egrave; was obviously given in the definition of the trim.
The SL 63 4MATIC + model, in particular, adopts the ACTIVE RIDE CONTROL AMG with a hydraulic anti-roll system active. SL & egrave; equipped as standard with a steering rear axle that works up to a speed; of 100 km/h. 6 AMG DYNAMIC SELECT driving programs are available. The brakes are carbon ceramic in order to better manage the very high performance of this car.
Obviously, all the most important are present; recent driving assistance systems developed by Mercedes.
