- Real-time display of the lateral and linear acceleration combined with the braking performance and the accelerator position, including a memory function
- Record individual lap times on a closed track, with the sector times and memory function
- Integrating DRIVE UNIT, to save your data into memory and initiate RACE START
Different functions are shown AMG Performance Media color display integrated into the dashboard. Three displays are shown at any time, with the most important information is located in the center. Digital simulation tools dial with red pointers ensure outstanding clarity.
Specifically reinforced aluminum spaceframe, low curb weight
In addition to maximum comfort, a key factor in driving pleasure in the new SLS AMG Roadster has outstanding performance. The reason for this is an innovative body design: the chassis and body made of aluminum design that combines intelligent lightweight construction with high durability. At curb weight of 3661 kg (estimated) Roadster only 88 pounds heavier than the coupe. The result is a remarkable power to weight ratio of 6.5 pounds per horsepower.
To achieve the same level of dynamics - no fixed roof, Mercedes-Benz SLS AMG Roadster includes several features specifically designed to strengthen the body, including side skirts with larger wall thickness and additional cameras. Dashboard cross-member is supported against the frame of the windscreen and the central tunnel of the additional racks, and a curved rack between the soft-top and tank strengthens the rear axle. The absence of a roof and gull-wing doors means that the open-top SLS AMG is the strengthening of cross-over seats to support fixed rollover protection system. It also contains 250-watt subwoofer explosion & Olufsen BeoSound AMG high-end sound system.
All this prevents unwanted vibrations from the beginning, and eliminates the need for additional, weight increasing vibration dampers, which are often found in open sports cars. Weight-optimized aluminum frame weighs 536 pounds, tipping the scales at just 4.5 pounds more than the gullwing model.
Intelligent mix of materials and a low center of gravity 50 percent of cleverly designed, and weight-optimized aluminum frame is made of aluminum, 26 percent of the aluminum sheet, 18 percent of cast aluminum and 6 percent were. The maximum passenger safety requires the use of ultra-high strength, heat-formed steel pillars.
The whole car was designed to achieve the lowest possible center of gravity. This applies to the lowest point of connection of the transmission and axles, as well as the location of the rigid structure of the body that was as low as possible. Examples include hard to bend and twist ties between the front and back of the cage and the safety of passengers, which were designed to use the power of paths that are as low as possible.
Powerful AMG 6.3-litre V8 engine with 563 hp
Mercedes-Benz SLS AMG Roadster has the same muscular engine, gull-wing model. 6.3-liter V8 with a maximum output of 563 hp at 6800 rpm makes open-top SLS one of the most powerful sports cars in its segment. Its power to weight ratio of 6.5 pounds per horsepower. This naturally aspirated engine produces maximum torque of 479 lb-ft at 4750 rpm. Convertible SLS AMG accelerates from zero to 60 miles / h in 3.7 seconds (0-100 km / h in 3.8 seconds) and top speed is 197 miles / h / 317 km / h (electronically limited) - this means that roadster has almost identical performance wing of a seagull.
High-revving 6.3-liter V8 engine has the typical characteristics of powerful engine racing. It responds instantly and effortlessly to accelerator movements. The use of dry sump lubrication system can significantly lower the installation in a car that has a low center of gravity for higher lateral acceleration and thrilling driving dynamics.
Achieving the required targets fuel consumption Despite his uncompromising sportiness, fuel consumption has also been considered. SLS AMG consumes 13.2 liters per 100 kilometers (NEDC combined), corresponding to CO2 emissions of 308 grams per kilometer. Efficiency improvements include familiar AMG-exclusive, friction optimized two-wire arc-spray coating on the cylinder walls, as well as on-demand card optimized oil supply and intelligent control of the generator: when an overflow phase motor, the kinetic energy is used to recharge the battery, and not just wasted heat. On the other hand, the generator is switched to idle during acceleration, thus reducing the load on the engine. Sophisticated technology allows the catalytic converter current and future emission standards such as Euro 5, LEV 2 and ULEV that must be met.
Rev-matching transmission with transaxle configuration and torque tube
AMG 6,3-liter V8 engine delivers its abundant power to the rear through an ultra-light carbon-fiber box driveshaft - similar to the setup used in the DTM C-Class car racing tour. On comparing the transmission is mounted on the rear (CAT), and connected to the casing of the engine with torque tube. Carbon shaft rotates at engine speed at the time of the pipe. The advantages of this complex solutions lie in the tight coupling between the engine and transmission, and, in turn, support the optimal power and torque.
SPEEDSHIFT DCT AMG 7-speed sports transmission boasts faster shifting gears without losing traction - in just 100 milliseconds. The driver a choice of four different driving modes: "C" (Controlled Efficiency), «S» (Sport), "S +" (Sport plus) or "M" (Manual). In sport, sport and manual modes, plus automatic mapping of function is activated, all modes can be selected via a convenient knob AMG DRIVE. RACE START function ensures optimum traction at full power launches off the ground - as well as mechanical differential lock, which is built into a compact body transfer.
Complex circuit suspension with double wishbone axle The front mid-engine configuration, plus a box provides the perfect front / rear weight distribution from 47 to 53 percent. Mounting the engine behind the front axle made a perfect driving dynamics with precise steering, excellent agility, low inertia for a spontaneous change of direction, and outstanding traction. All four wheels are on the double-wishbone with a track rod technology, which has proved to be right up to Formula 1 motor racing. With double-wishbone axle, the location of the wheels and suspension functions remain separate, spring / depreciation rack supported on the lower wishbone. Double wishbone setup with the collapse of its high rigidity and a positive track is a wheel with minimal elastic movements, providing the driver optimum road contact feel when driving on the limit.
Wishbones, steering knuckles and hub carriers front and back are made entirely from forged aluminum - a significant reduction in unsprung masses, this configuration also noticeably improves suspension response. Wheelbase 105.5 inches, not only leads to an outstanding straight-line stability, but also low-load on the wheel changes, which significantly reduces the tendency of the vehicle to dive and squat under braking and acceleration. Wide track - 66.2 inches front, 65.1 inches rear - ensures a lower wheel load shifts from internal to external rotation of the wheel when providing tires to save more grip.
New Adaptive AMG Sport Suspension
The new AMG sports suspension adaptive electronically controlled damping available as an attractive alternative to the standard suspension, AMG sport. This gives the damping characteristics to be changed at the touch of a button. Using the buttons on the AMG DRIVE UNIT, the driver can choose his own suspension settings. There are three modes: "comfort", "Sport" and "Sport Plus". The current mode is displayed on the instrument cluster.
"Comfort" provides a sensitive response to the soft damping characteristics, and in the "Sport" mode, the shock absorbers have much stiffer response, depending on road conditions. This not only leads to improved road contact, but also effectively suppresses body roll and pitching. "Sports Plus" is ideal for demanding laps on the track: in addition to higher braking force, the regime comes to the specific control algorithms, which were made specifically for sporty driving. New, variable suspension also will be optionally available for SLS AMG coupe in the future.
Optional AMG ceramic high-performance two-piece braking system
AMG a powerful braking system with two parts of the brake discs on the front ensures extremely short braking distances, even with huge loads. The red-painted brake calipers on all four corners are available as an option. Additional ceramic two-piece brake discs with even more to provide even better braking. Ceramic brake discs perform at even higher operating temperatures due to their greater rigidity, all coupled with impressive weight loss by about 40 percent. Reducing unsprung mass to further enhance both comfort and grip, and reduced rotating mass on the front axle provides more direct steering response.
Lightweight construction was the key when it comes to wheels: alloy wheels with innovative flows forming principle reduce unsprung weight, improving driving performance and suspension comfort. In addition to the standard AMG twin 5-spoke alloy wheels, a 7-spoke wheels, which is available as a no cost option. Weight-optimized 10-spoke forged wheels available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) is designed specifically for the SLS AMG ensure optimum performance. Tire pressure monitoring system is standard to constantly monitor tire pressure of all four wheels, with a separate display for each tire.
