Back in 2011 Senner Tuning announced an upgrade package for the Mercedes SLS AMG Coupe version. Today, the same package has been extended to the roadster version . Just like with the coupe , the roadster version receives an extra 35 horsepower under the hood and new wheels, combined with an upgraded suspension system.
Senner Tuning added a new exhaust system made in high-grade steel and a new set of high-performance air filters to help boost its output beyond the standard 571 horsepower and 650 Nm (479 pound-feet) of torque. The end result is an SLS Roadster that delivers a total of 606 horsepower and a peak torque of 508 pound-feet. AS standard, the SLS AMG hits 100 km/h (62 mph) in just 3.8 seconds and a top speed of 197 mph. This package likely drops its acceleration time down to around 3.7 seconds and it may allow the SLS AMG to tickle the 200-mph mark.
Senner also installed new wheels, sized 9-by-20 inches with 255/30R20 tires up front and 11.5-by-21 inches with 295/25R21 Hankook S1 Evo-tires for the rear. The wheels are painted in titanium gray and are combined with a special coil-over suspension system made by KW Automotive.
