The introduction of the new SLS 2012 AMG by Roger Federer. That ad sounds a little far-fetched but do like it. The SLS AMG features a 6.2L V8 engine delivering 563hp/ 479lb-ft of torque. I find the roadster edition of the SLS really nice. Mercedes did there best to add the soft top without affecting the performance of the car by adding weight. The result was an add of just 88 pounds to the car’s total weight thanks to the use of very light but strong aluminium in the composition of the convertible mechanism.
