2011 Mercedes-Benz SLS AMG GT3 Review

Automobile fascination coupled with a design spectacular car racing - it's the new Mercedes-Benz AMG SLS GT3. Racing AMG version of the SLS is designed as a sports car for customer participation in the racing series based on the FIA ​​GT3 regulations. Warning light and optimized chassis, brakes and aerodynamics deliver uncompromising dynamics. The special supplement AMG Mercedes-Benz SLS will debut race in 2011.

The sleek design and the breathtaking form of the Mercedes-Benz AMG SLS was actually enhanced by targeted modifications to the bodywork. The new components made mainly of lightweight carbon fiber gives a clear indication of outstanding racetrack performance and extensive aerodynamic development work.

Forward, boasts of a GT3 race car new front skirt with enlarged air intakes. The wide opening in the grille with large specific Mercedes star and wing-shaped fins horizontal supply air to the discs engine oil cooler and brakes. The same function is served by two doses for the bi-xenon headlights vertically. Down Force on the front axle is courtesy of four external side mounted cops, and a carbon front splitter, it flows directly into the smooth underbody panel that connects to the rear diffuser.

The bonnet has a central opening of extraction of the heat engine when the openings in the front fenders in order to facilitate the flow of a wheel. weight optimization measures include the application of ultra-lightweight polycarbonate side and rear windows and the windscreen and, if desired.

The wings were extended forward and backward to accommodate large racing tires. With a width of 78.3 inches, the GT3 interpreter is a good 2 inches wider than the series production at Mercedes-Benz AMG SLS. The new thresholds based on the openings to cool the rear brakes, with the bottom, without any visible problems along the lower thresholds. Home pillar B fuel tank standard card system for rapid filling. The 31.7 liters fuel tank is located behind the driver.

Large carbon rear wing

Viewed from behind the Mercedes-Benz AMG SLS GT3 dominate its impressive size. First session through the tailgate rear spoiler in carbon fiber is widely adjustable and can facilitate the installation complete track to meet the individual property. New rear skirt suits two openings, which convey the air to the rear wheel arches. In addition, a visual highlight is the carbon fiber rear diffuser, rear axle stands gracefully in a continuation of a smooth surface, its form more downforce. General aerodynamic concept by Mercedes-Benz AMG GT3 SLS has been analyzed and defined through extensive testing in wind tunnel and on track.

The black exhaust pipes deliver a final appeal at the same time, property of the AMG eight-cylinder. The regulation consists of light rain in the tailgate - which must be ignited by the pilot in bad weather.

Near mass production 6.3-liter V8 AMG

As defined in the rules of the FIA ​​GT3, the AMG 6.3-liter V8 is almost identical to the mass production of the vehicle. Thank you to its light weight, acceleration figures GT3 - 3.7 seconds to sprint from 0 to 60 km / h - is much less than the figures already very good for production vehicle. According to the train, top speed exceeding 186 km / h.

V8 AMG 6.3-liter dry-sump lubrication used in racing cars, too. Using a suction pump and pressure tank and external oil sump means that conventional oil can be omitted. This technology ensures reliable lubrication of the engine in high lateral acceleration, the kind usually seen on the ground.

dry sump lubrication also allows low mounting position for the V8 engine - one of the most important technological strengths of the Mercedes-Benz AMG SLS. The solution - the installation of eight cylinders as low as possible and as a front-engine mid-behind the front axle, combined with a layout of trans-axle transmission - resulting in excellent weight distribution.

six-speed transmission with sequential shift racing

Unlike the mass production of the vehicle, Mercedes-Benz AMG SLS GT3 is equipped with a six-speed sequential gearbox racing. Thanks to its compact design, racing package of income transfers offers significant benefits - in the final version of the GT3 is the ground clearance under the machine to mass production. Driver moves the gear shift levers on the steering wheel. The transmission is mounted directly on the rear axle and connected to the V8 engine through a torque tube, which is very high bending and torsional stiffness. This offers significant advantages when it comes to dynamics, because this is a sophisticated solution allows the entire disc is expected to play a lot less. In addition, traction control, multi-plate differential lock integrated into the transmission for excellent acceleration characteristics. Inside the torque tube, the shaft rotates at a speed.

As in the model of mass production, and Mercedes-Benz C-Class DTM touring, the shaft is carbon fiber.

Its long wheelbase, low center of gravity and wide track, SLS AMG concept is a pre-end path - the strengths are precise shifts of property, the agility of the first class, with low inertia, under the direction of the limit and sudden High cornering.

It requires only minor adjustments to complete the performance track. Lightweight aluminum frame with a double wishbone suspension at all four corners have been changed to take account of the kinematics of the lower vehicle height. The range of adjustment options to facilitate the optimal path changes according to individual properties and the weather variables. As well as the ability to change the spring and damper assembly is also free to change track and camber, the height of the vehicle and the front and rear legs.

Like SLS series AMG, the GT3 version also features a steering rack and pinion steering with speed-sensitive. The ratio of input to direct more agile handling even on the ground.

Racial AMG brake system with composite technology

Shortest distance for braking, the highest stability and optimum management guaranteed by the AMG racing brake system. All four corners of the brake discs of the composite technology motorsport testing. Axial and radial gray iron disks attached to a liquid aluminum cap with stainless steel components composite. This sophisticated technology allows for excellent heat dissipation and thus the reliable stability. Mercedes-Benz AMG SLS GT3 is equipped with a precise calculation of the cooling channels - the openings of the skirt front and rear wheels directly opposite the flow of fresh air to the brake discs. The four brake discs are vented, slotted and drilled. Six-pot fixed calipers on the rear axle and four-pot fixed calipers, finished in anthracite with AMG logo in white, provides plenty of pad surface. An antilock braking system with special options come standard racetrack.

Due to space constraints, AMG high-performance brake system with ceramic composite, optional on the production car, is not compatible with 18-inch wheels ordered by the FIA ​​regulations.

AMG center-lock - 12x18 inches 13x18 inches front and rear - are equipped with racing tires in sizes 11.3 x 26.9 inches (front) and 12.4 x 27.9 inches (rear). Depending on the application, the slicks are available free to the intermediate or rain tires. The classic multi-spoke design aid ventilation of the braking system. quick pit stop and change the wheel are provided by the pneumatic jacking system integrated into the chassis. Four pneumatic pistons lift GT3 race car with about 7.5 inches, so the team in the pits to change tires racing double quick time.

Interior with racing bucket seat and the racing wheel

When opening gullwing doors, showing the Mercedes-Benz AMG SLS GT3 a functional layout with a strong race car print. The driver sits in a seat race seat features a six-point harness and the HANS (Head and Neck), which solves the helmet in place in case of accident, which minimizes the risk of injury. Additional security comes courtesy of the steel cage, which also contributes to the promotion of the proposed aluminum frame.

A flywheel with a diameter of 13 inches makes perfect control of the vehicle. Because it is opened up, the pilot always has a perfect view of the central screen, which contains all relevant information such as road speed, engine speed, operating temperature, lap time and gear selection. The steering wheel has a quick release mechanism that allows the entry and exit of the vehicle much easier. Switches on the steering wheel hub allow the driver to activate additional features such as radio pit, high beams, and the supply of drinking water. Additional controls are mounted on the center console and includes on / off function for the AMG V8 engine, traction control and reverse - in the case - the integrated fire extinguisher. Controls the balance of brake adjustment is placed on the torque tube tunnel.

A close relationship with GT3 and its mass production of the same level, as evidenced by the indicators, which is highly strained airfoil provides a visual width. Integrated into the dashboard of a highly distinctive vents galvanized "Silver Shadow" and adjustable nozzles to form a cross - its shape resembles a jet engine.

Deliveries to customers 'vehicles', starting in 2011
