PRESENTADO!! 4 motores eléctricos síncronos: 552 kW y 1.000 Nm de par Peso: 2095 Kg 0-100 km/h: 3,9 s Velocidad máxima: 250 km/h Precio en Alemania: 416500 €      ______________________________________________ Su seguimiento Electrico   Mercedes AMG SLS e-drive: confirmed by Volker Mornhinweg. 4 electric motors near the wheels, 392 kW/533hp, 880 NM, AWD. 0-100 kmh in less than 4 seconds, 200kmh max. 324 Li-Ion cells, placed where the torque-tube is. Means extremely low CoG, fantastic balance. 150 to 180 kms autonomy. Regulation of the torque independantly for each of the 4 wheels, and of course energy-recovery when braking. Mercedes will release only one SLS e-drive, later a small serie. AMG Mercedes engineers are well advanced on a plug-in electric version of the upcoming SLS. Tentatively planned for limited production in 2015, the new zero-emission supercar draws heavily on the production version of the yet-to-be-revealed SLS, which is scheduled to get its first public outing at the Frankfurt motor show on 15 September. The SLS eDrive is planned to be offered with the same lightweight aluminium body as the production version of the SLS, complete with its signature gullwing doors. The new car is also set to take the standard interior, albeit with some minor changes to the switchgear to reflect the electric driveline. According to official Mercedes-Benz AMG information seen by Autocar, the SLS eDrive will use a heavily modified version of the standard SLS’s rear-wheel-drive platform. Among the changes aimed at accommodating the new hardware is the inclusion of a new pushrod front suspension, with coilover damper units mounted horizontally in place of the standard car’s more conventional upright double wishbone arrangement to free up space around the front axle. This allows the fitment of two 98kW (133bhp) motors up front, effectively turning the SLS eDrive into a four-wheel-drive vehicle. Each of the front wheels is driven via a planetary drive set that acts like a torque vectoring device, providing drive to the wheel possessing the most traction. The set-up at the front is mirrored at the rear; each back wheel is powered by a 98kW (133bhp) motor that drives through a planetary drive set, although the standard rear double wishbones have been retained without modification. All up, the SLS eDrive possesses 392kW (532bhp) and a sturdy 649lb ft of torque. By comparison, the standard SLS, powered by a heavily reworked version of AMG’s familiar 6.2-litre V8 engine, boasts 420kW (571bhp) and 479lb ft. Performance figures aren’t official yet, but Wolf Zimmermann, the man heading up SLS eDrive development, claims 0-62mph acceleration in under 4.0sec and a top speed in excess of 120mph. The battery pack is mostly mounted low down in the space usually taken up by the standard SLS’s torque tube. AMG is also planning to use the space behind the seats, usually taken up by the fuel tank, for additional battery capacity. Range is put at between 93 and 112 miles depending on the load placed on the battery, while overall recharging time is put at between five and six hours on high-density charge or eight hours on conventional mains power. Measures such as brake energy regeneration are likely to feature too. |

Affalterbach – Mercedes-AMG is paving the way ahead: with the new SLS AMG with electric drive, the performance brand within Mercedes-Benz Cars is developing an exciting super sports car with zero-emission high-tech drive. This model sees Mercedes-Benz and AMG displaying their expertise in the development of alternative drive solutions for high-performance super sports cars, delivering further proof of their pioneering status in this market segment. The Mercedes-Benz SLS AMGwith electric drive transforms the vision of powerful and locally emission-free super sports cars into reality thanks to an innovative drive system: powerful forwards thrust is provided by four electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. The four electric motors are positioned near the wheels, substantially reducing the unsprung masses compared to wheel-hub motors. One transmission per axle transmits the power. This intelligent all-wheel-drive system allows dynamically optimised power transmission without any losses by means of Torque Vectoring – in other words the specifically targeted acceleration of individual wheels. In its first pilot phase, the SLS AMG with electric drive incorporates a liquid-cooled high-voltage lithium-ion battery of modular design with an energy content of 48 kWh and a capacity of 40 Ah. The 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven. Acceleration from zero to 100 km/h in around 4 seconds When it comes to dynamics, the electrically driven SLS AMGdelivers an unequivocal statement: the swing-wing model accelerates from zero to 100 km/h in around 4 seconds – putting it on the same high level as the SLS AMG with a 6.3-litre V8 engine developing 420 kW/571 hp. "With the SLS AMG with electric drive, we wanted to redefine the super sports car. For us, it is not just about responsibility. We attach just as much importance to excitement and classic AMGperformance," says Volker Mornhinweg, Chief Executive Officer of Mercedes-AMG GmbH. Optimum weight distribution and low centre of gravity. The purely electric drive system was factored into the equation as early as the concept phase when the new swing-wing model was being developed by Mercedes-Benz and AMG. It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of example, the four electric motors and the two transmissions can be positioned near the wheels and very low down in the vehicle. The same applies to the modular high-current battery, whose modules are located in front of the firewall, in the centre tunnel and behind the seats. Advantages of this solution include the vehicle's low centre of gravity and the balanced weight distribution – ideal conditions for optimum handling, which the electrically powered SLS AMG shares with its petrol-driven sister model. Key data at a glance: Mercedes-Benz SLS AMG with electric drive Max. output 392 kW Torque 880 Nm 0-100 km/h Approx. 4 s Rated capacity 40 Ah (at 400 V) Energy content 3x 16 kWh = 48 kWh The installation of the drive components required no changes whatsoever to the swing-wing model's aluminium spaceframe body. And there were just as few constraints when it came to maintaining the excellent level of passive safety and high degree of long-distance comfort that are hallmarks of Mercedes cars. Strategic alliance for fast electrification of the car The electrically powered SLS AMG sees Mercedes-Benz and AMGcontinuing to pursue their aim of minimising the amount of time it takes to bring about the electrification of the car. Their strategic involvement in Deutsche Accumotive GmbH & Co. KG, a joint venture between Daimler AG and Evonik Industries AG, will provide the battery technology required in future. Daimler has the leading role in this joint venture for the development and production of batteries and battery systems for automotive applications. Mercedes AMG |

Esta bastante bien, lo unico malo es que el que se compra un coche de 4 segundos en el 0-100 querrá hacer mas de 160 km de un tirón, o por lo menos yo lo veo de esa forma. De todas formas es un tema muy bueno. P.D. si no me equivoco el Tesla tenía mas autonomía no? |

nota de prensa, en inglés With the electric drivetrain system of the SLS AMG E-CELL, Mercedes-AMG GmbH is providing yet another glimpse of its latest development project. The drivetrain has been in development since 2010 as a result of the cooperation between Mercedes-AMG and Mercedes AMG High Performance Powertrains in Brixworth. Four synchronous electric motors located near the wheels, providing a peak output of 392 kW and torque of 880 Nm, help to provide the SLS AMG E-CELL with its exciting driving dynamics. The carbon-fibre transmission tunnel, which also serves as the monocoque housing for the high-voltage battery modules, is structurally integrated into the aluminium body shell and firmly bonded to it. The lightweight fibre composite materials have their origins in the world of Formula 1, among other areas. A small series-production run of the Mercedes-Benz SLS AMG E-CELL is expected to be launched onto the market in 2013. The powerful and locally emission-free super sports car with electric drive is yet another example of the innovative strength and development competence of the AMG performance brand. The ground-breaking drive system of the technology vehicle boasts some outstanding features: powerful traction is provided by four synchronous electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. The four compact electric motors each achieve a maximum rotational speed of 12,000 rpm and are positioned close to the wheels. As a result, compared with wheel-hub motors, the unsprung masses are substantially reduced. One transmission per axle transmits the power. Acceleration from zero to 100 km/h in 4 seconds When it comes to dynamics, the electrically-powered SLS makes a statement: the gullwing model accelerates from zero to 100 km/h in 4 seconds – which almost puts it on the same high level as the SLS AMG with 6.3-litre V8 engine developing 420 kW (571 hp), which can accelerate to 100 km/h in 3.8 seconds. Further exciting touches are provided courtesy of the agile accelerator response and the straight-line performance: unlike a combustion engine, torque build-up in an electric motor is instantaneous – maximum torque is available virtually from a standstill. The spontaneous torque build-up and confident power delivery - which does not suffer from any interruption of tractive power - are combined with engine running characteristics which are totally free of vibration. The key data at a glance: SLS AMG E-CELL Max. output 392 kW Torque 880 Nm 0 - 100 km/h 4.0 s Energy content 3 x 16 kWh = 48 kWh All-wheel drive with torque vectoring enables completely new levels of freedom Four wheels, four motors – the intelligent and permanent all-wheel drive of the electric SLS guarantees driving dynamics at the highest level, while at the same time providing the best possible active safety. Optimum traction is therefore ensured, whatever the weather conditions. According to the AMG developers, "torque vectoring" involves the individual control of the electric motors, something which enables completely new levels of freedom to be achieved. Torque vectoring is permanently active and allows for selective distribution of forces for each individual wheel. The intelligent distribution of drive torque greatly benefits driving dynamics, handling, driving safety and ride comfort. Each individual wheel can be electrically driven and electrically braked, depending on the driving conditions, thus helping to
Advanced technology from Formula 1: high-voltage lithium-ion battery The SLS AMG E-CELL incorporates a liquid-cooled high-voltage lithium-ion battery featuring a modular design with an energy content of 48 kWh. Its development has made use of advanced technology from the world of Formula 1: the battery is the first result of the co-operation between Mercedes-AMG GmbH in Affalterbach and Mercedes AMG High Performance Powertrains (formerly Mercedes-Benz High Performance Engines). Headquartered in Brixworth, England, the company has been working closely with AMG for a number of years. F1 engine experts have benefited from its extensive expertise with the KERS hybrid concept, which made its debut in the 2009 Formula 1 season. At the Hungarian Grand Prix in 2009, Lewis Hamilton achieved the first historic victory for a Formula 1 vehicle featuring KERS hybrid technology in the form of the Mercedes-Benz KER System. The high-voltage battery consists of 12 modules each comprising 72 lithium-ion polymer cells. This optimised arrangement of a total of 864 cells has benefits not only in terms of best use of the installation space, but also in terms of performance. The maximum electric load potential of the high-voltage battery is 480 kW, which is an absolute best value in the automotive sector. Another technical feature of this considerable performance is the intelligent parallel circuit of the individual battery modules – this also helps to maximise the safety, reliability and service life of the battery. As in Formula 1, the 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven. High-performance control as well as effective cooling of all components A high-performance electronic control system converts the direct current from the high-voltage battery into three-phase alternating current which is required for the synchronous motors and regulates the energy flow for all operating conditions. Two low-temperature cooling circuits ensure that the four electric motors and the power electronics are maintained at an even operating temperature. A separate low-temperature circuit is responsible for cooling the high-voltage lithium-ion battery. In low external temperatures, the battery is quickly brought up to operating temperature with the aid of an electric heating element. This helps to preserve the overall service life of the battery. In extremely high external temperatures, the cooling circuit for the battery can be additionally boosted with the aid of the air conditioning system. "AMG Lightweight Performance" design strategy The trailblazing body shell structure of the SLS AMG E-CELL is part of the ambitious "AMG Lightweight Performance" design strategy. The battery is located within a carbon-fibre monocoque which forms an integral part of the body shell and acts as the gullwing model's "spine". The fibre composite materials have their roots in the world of Formula 1, among other areas. The advantages of carbon-fibre were exploited by the AMG engineers in the design of the monocoque. These include their high strength, which makes it possible to create extremely rigid structures in terms of torsion and bending, excellent crash performance and low weight. CFRP components are up to 50 percent lighter than comparable steel ones, yet retain the same level of stability. Compared with aluminium, the weight saving is still around 30 percent, while the material is considerably thinner. The weight advantages achieved through the carbon-fibre battery monocoque are reflected in the agility of the SLS AMG E-CELL and, in conjunction with the highly innovative wheel-selective four-wheel drive system, ensure true driving enjoyment. The carbon-fibre battery monocoque is, in addition, conceived as a "zero intrusion cell" in order to meet the very highest expectations in terms of crash safety. It protects the battery modules inside the vehicle from deformation or damage in the event of a crash. The basis for CFRP construction is provided by fine carbon fibres, ten times thinner than a human hair. A length of this innovative fibre reaching from here to the moon would weigh a mere 25 grams. Between 1000 and 24,000 of these fibres are used to form individual strands. Machines then weave and sew them into fibre mats several layers thick, which can be moulded into three-dimensional shapes. When injected with liquid synthetic resin, this hardens to give the desired structure its final shape and stability. Through their experience with the SLR, the AMG Black Series vehicles and in motorsport, Mercedes-Benz and AMG have accumulated more than 10 years of expertise in working with carbon-fibre materials. AMG currently makes the propshaft for the SLS AMG, for example, in carbon-fibre. On the SLS Roadster, the supporting structure for the draught-stop is made as standard as a carbon sandwich structure. This component, with extremely short cycle times in an industrially oriented manufacturing process, already demonstrates what will be possible in the future. Optimum weight distribution and low centre of gravity The purely electric drive system was factored into the equation as early as the concept phase when the gullwing model was being developed. It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of example, the four electric motors and the two transmissions can be positioned as close to the four wheels as possible and very low down in the vehicle. The same applies to the modular high-voltage battery. Advantages of this solution include the vehicle's low centre of gravity and balanced weight distribution – ideal conditions for optimum handling, which the electrically-powered gullwing model shares with its petrol-driven sister model. New front axle design with pushrod damper struts The additional front-wheel drive called for a newly designed front axle: unlike the series production vehicle with AMG V8 engine, which has a double wishbone axle, the SLS AMG E-CELL features an independent multi-link suspension with pushrod damper struts. This is because the vertically-arranged damper struts in the series SLS had to make way for the additional drive shafts. As is usual in a wide variety of racing vehicles, horizontal damper struts are now used, which are operated via separate push rods and transfer levers. Thanks to this sophisticated front-axle design, which has already been tried and tested in the world of motorsport, the agility and driving dynamics of the SLS AMG E-CELL attain the same high levels as the V8 variant. Another distinguishing feature is the speed-sensitive power steering with rack-and-pinion steering gear: the power assistance is implemented electrohydraulically rather than just hydraulically. AMG ceramic composite brakes for perfect deceleration The technology vehicle is slowed with the aid of AMG high-performance ceramic composite brakes, which boast extremely short stopping distances, a precise actuation point and outstanding fade resistance, even in extreme operating conditions. The over-sized discs – measuring 402 x 39 mm at the front and 360 x 32 mm at the rear – are made of carbon fibre-strengthened ceramic, feature an integral design all round and are connected to an aluminium bowl in a radially floating arrangement. The ceramic brake discs are 40 percent lighter in weight than the conventional, grey cast iron brake discs. The reduction in unsprung masses not only improves handling dynamics and agility, but also ride comfort and tyre grip. The lower rotating masses at the front axle also ensure a more direct steering response – which is particularly noticeable when taking motorway bends at high speed. The ABS and ESP® systems have been adapted to match the special application spectrum of the permanent all-wheel drive. |
