    The SLS AMG Mercedes received one more tuning package which made this vehicle one of the most high-performance project cars on the today's market. This latest package belongs to the aftermarket experts – RENNtech. In the past this tuning shop has already produced performance packages for the SLS AMG.

    This package made the Mercedes supercar way more powerful than it was before. The tuning package features the company’s own tube headers that are made from high quality metal, 200 cell sport catalytic cells that have been ceramic coated in order to cut down the heat in the engine compartment while also fighting off the thermal stress of the engine.

    The design of the tubes higher the torque numbers improving overall performance of the car. After the tuning of the engine was done there were received following figures: the stock power output of the 6.3-liter V8 engine is 563 hp and 479 lb/ft of torque, after the tuneup the power output is 583 hp with 500 lb/ft of torque. These numbers cannot be called breathtaking, though they will keep the roadster ahead of its brethren.

    The new SLS AMG roadster is designed so that any car enthusiast will recognize the shape of the AMG roadster. Anyone with some knowledge of recent Benz history knows that the addition of a more expensive convertible was just a matter of time. This roadster was designed and developed along with an SLS coupe, that is why engineers used the same 6.2L V8 producing 563hp, featured with seven-speed transmission.

    In comparison with the coupe version convertible has less “solid” body, in order to compensate this, engineers used a system of crossbars at the front and rear of the roadster's body. One is behind the dashboard, another is between the top and the gas tank. These crossbars compensate the lack of a fixed roof. Between the seats there is one more crossbar, it works as an attachment for the roll hoops and an enclosure for the Bang & Olufsen subwoofer. The vehicle weights 3792 pounds. In comparison with the coupe version it's a bit slower, (runs to 60mph in 3.5 seconds) though this is normal for the convertible. The top can be easily displaced at speeds up to 31 mph.

    The new SLS roadster will be presented at the Frankfurt auto show in September and will be available for sale in the U.S. by the end of the year. The price tag is expected to hit the mark of $187,450.
