With the electrical operated drivetrain program of the SLS AMG E-CELL, Mercedes-AMG GmbH is offering yet another look of its newest progression venture. The drivetrain has been in progression since 2010 due to the collaboration between Mercedes-AMG and Bmw AMG Great Efficiency Powertrains in Brixworth. Four synchronous electric operated applications situated near the tires, offering a high outcome of 392 kW and twisting of 880 Nm, help to provide the SLS AMG E-CELL with its interesting driving features. The carbon-fibre indication tube, which also assists as the monocoque real estate for the high-voltage power supply segments, is structurally incorporated into the aluminum body spend and strongly insured to it. The lightweight fiber blend components have their roots in the world of System 1, among other areas.
A small series-production run of the Mercedes-Benz SLS AMG E-CELL is predicted to be released onto the market in 2013. The highly effective and in the area emission-free extremely sports car with electric operated generate is yet another example of the modern durability and progression proficiency of the AMG performance brand name.
The ground-breaking generate program of the technological innovation vehicle features some excellent features: highly effective extender is offered by four synchronous electric operated applications with a mixed high outcome of 392 kW and a highest possible twisting of 880 Nm. The four lightweight electric operated applications each obtain a highest possible spinning speed of 12,000 rpm and are situated close to the tires. Consequently, in contrast to wheel-hub applications, the unsprung public are considerably decreased. One indication per axle sends the energy.
Acceleration from zero to 100 km/h in 4 seconds
When it comes to features, the electrically-powered SLS makes a statement: the gullwing style boosts from zero to 100 km/h in 4 a few moments – which almost places it on the same advanced level as the SLS AMG with 6.3-litre V8 website creating 420 kW (571 hp), which can improve to 100 km/h in 3.8 a few moments.
Further interesting variations are offered complimentary of the nimble reduce reaction and the straight-line performance: as opposed to a burning website, twisting build-up in an motor unit is immediate – highest possible twisting is available essentially from a halt. The natural twisting build-up and assured energy shipping - which does not experience from any disruption of tractive energy - are in addition to website running features which are no cost of shake.

All-wheel generate with twisting vectoring allows absolutely new stages of freedom
Four wheels, four applications – the brilliant and permanent all-wheel generate of the electrical powered SLS assures generating characteristics at the highest level, while at the same time providing the best possible dynamic protection. Optimum extender is therefore ensured, whatever the circumstances. According to the AMG developers, "torque vectoring" involves the person control of the electrical powered applications, something which allows absolutely new stages of independence to be achieved. Torque vectoring is completely dynamic and allows for selective submission of forces for each personal rim. The brilliant submission of generate twisting greatly benefits generating characteristics, handling, generating protection and ride comfort. Each personal rim can be power driven and power braked, depending on the generating circumstances, thus helping to optimize the vehicle's cornering properties, decrease the tendency to oversteer/understeer, improve the yaw damping of the basic vehicle, decrease the guiding effort and guiding position required, improve extender, and reduce ESP® intervention.
Twisting vectoring allows the best possible use of the bond potential between the car tyres and the road exterior in all generating conditions, thereby increasing the crucial boundaries of the car generating characteristics.
Innovative technological innovation from Program 1: high-voltage lithium-ion battery
The SLS AMG E-CELL carries a liquid-cooled high-voltage lithium-ion power supply presenting a flip design with an power content of 48 kWh. Its development has created use of advanced technological innovation from the world of Program 1: the power supply is the first result of the co-operation between Mercedes-AMG GmbH in Affalterbach and Bmw AMG Great Efficiency Powertrains (formerly Mercedes-Benz Great Efficiency Engines). Based in Brixworth, Britain, the company has been working carefully with AMG for a period of time. F1 engine experts have helped from its comprehensive expertise with the KERS multiple concept, which created its introduction in this year's Program 1 season. At the Hungarian Lavish Corrt last year, Lewis Hamilton obtained the first ancient success for a Program 1 vehicle presenting KERS multiple technological innovation in the form of the Mercedes-Benz KER Program.
The high-voltage power supply is made up of 12 segments each composed 72 lithium-ion plastic tissue. This optimized design of a total of 864 tissue has benefits not only with regards to best use of the installation space, but also with regards to performance. The maximum power load potential of the high-voltage power supply is 480 kW, which is an absolute best value in the vehicle industry. Another technical feature of this significant performance is the brilliant similar routine of the individual power supply segments – this also allows to improve the safety, stability and assistance power supply. As in Program 1, the 400-volt power supply is incurred by means of targeted recovery during stopping whilst the car is being pushed.
High-performance management as well as effective chilling of all components
A high-performance electronic management system transforms the dc from the high-voltage power supply into three-phase ac which is required for the synchronous applications and handles the power flow for all managing conditions. Two low-temperature chilling tour ensure that the four power applications and the power gadgets are managed at an even managing heat range. A individual low-temperature routine is responsible to chill the high-voltage lithium-ion power supply. In low exterior conditions, the power supply is quickly brought up to managing heat range with the aid of a powered heater. This allows to retain the overall assistance power supply. In higher than normal exterior conditions, the chilling routine for the power supply can be additionally increased with the aid of the ac system.
"AMG Compact Performance" style strategy
The trailblazing body spend framework of the SLS AMG E-CELL is aspect of the committed "AMG Compact Performance" style technique. The power supply is situated within a carbon-fibre monocoque which types a fundamental element of our body spend and functions as the gullwing model's "spine". The fiber blend materials have their origins in the world of System 1, among other areas. The benefits of carbon-fibre were utilized by the AMG designers in the style of the monocoque. These include their high durability, which makes it possible to create extremely firm elements in terms of torsion and twisting, excellent collision efficiency and low bodyweight. CFRP elements are up to 50 % brighter than similar precious metal ones, yet maintain the same level of balance. Compared with aluminum, the bodyweight saving is still around 30 %, while the content is significantly slimmer. The bodyweight benefits obtained through the carbon-fibre power supply monocoque are demonstrated in the speed of the SLS AMG E-CELL and, along with the highly modern wheel-selective four-wheel drive system, ensure true driving pleasure.
The carbon-fibre power supply monocoque is, in addition, created as a "zero attack cell" to satisfy the very maximum objectives with regards to collision safety. It defends the power supply segments inside the vehicle from deformation or damage in the event of a collision.
The base for CFRP development is offered by excellent as well as fibers, ten periods slimmer than a hair. A duration of this modern fiber attaining from here to the celestial satellite would think about a simple 25 h. Between 1000 and 24,000 of these fibers are used to type personal lengths. Devices then place and sew them into fiber pads several levels wide, which can be molded into three-dimensional forms. When shot with fluid artificial material, this solidifies to give the preferred framework its ultimate appearance and balance.
Through their encounter with the SLR, the AMG Dark-colored Sequence automobiles and in motorsport, Mercedes-Benz and AMG have gathered more than 10 years of encounter in working with carbon-fibre components. AMG currently makes the propshaft for the SLS AMG, for example, in carbon-fibre. On the SLS Roadster, the helping framework for the draught-stop is made as conventional as a as well as food framework. This element, with incredibly brief pattern periods in an industrially focused developing procedure, already shows what will be possible at some point.
The best possible bodyweight submission and low hub of gravity
The simply electric operated generate system was included into the situation as beginning as the idea stage when the gullwing style was being developed. It is essentially packed for the incorporation of the high-performance, zero-emission technology: by way of example, the four electric operated applications and the two signals can be located as close to the four tires as possible and very low down in the automobile. The same relates to the flip high-voltage power supply. Benefits of this remedy involve the car low hub of severity and healthy bodyweight submission – suitable circumstances for max managing, which the electrically-powered gullwing style stocks with its petrol-driven sis style.
New front side axle style with pushrod damper struts
The extra front-wheel generate known as for a recently developed front side axle: as opposed to the sequence generation automobile with AMG V8 website, which has a twice wishbone axle, the SLS AMG E-CELL functions an individual multi-link revocation with pushrod damper struts. This is because the vertically-arranged damper struts in the sequence SLS had to make way for the extra generate golf club shafts. As is regular in a large range of rushing automobiles, horizontally damper struts are now used, which are managed via individual force supports and exchange levers.
Thanks to this innovative front-axle style, which has already been tried and examined in the world of motorsport, the rate and driving characteristics of the SLS AMG E-CELL obtain the same great levels as the V8 version. Another specific function is the speed-sensitive energy guiding with rack-and-pinion guiding gear: the energy assistance is integrated electrohydraulically rather than just hydraulically.
AMG clay blend braking system for perfect deceleration
The technology vehicle is stunted with the aid of AMG high-performance clay blend braking system, which feature extremely short avoiding ranges, a accurate actuation point and excellent reduce level of resistance, even in excessive managing conditions. The over-sized dvds – calculating 402 x 39 mm at the top side and 360 x 32 mm at the back – are made of as well as fibre-strengthened clay, function an important style complete and are linked with an aluminum dish in a radially sailing design.
The clay braking system dvds are 40 percent light than the traditional, greyish certain braking system dvds. The reduction in unsprung public not only increases managing characteristics and rate, but also journey comfort and controls hold. The lower spinning public at the top side axle also ensure a more direct guiding reaction – which is particularly recognizable when taking freeway turns at high-speed. The ABS and ESP® systems have been tailored to match the special application array of the lasting all-wheel drive.
