We have seen pictures of the 2013 Mercedes-Benz SL-class before, first when pictures from its brochure got leaked, followed by the official release of images and specs about a month ago.
However, its unveil at the 2012 North American International Auto Show in Detroit, MI., is the first time it has been shown in the flesh. Like its predecessor, it has a folding metal roof, and the air scarf system, which blows hot air on your neck, perfect for driving with the top down even on cold days.
What is new about this new SL is its nearly all-aluminum construction. Due to this light-weight material, this new SL is 175 lbs lighter than the out-going model. Couple its lighter weight with the new 4.7-liter, turbo-charged, V8 which produces 429 hp and 516 lb-ft of torque, and you'll end up with a very quick rear-wheel drive car. 0-60 mph in the SL550 model now takes just 4.5 seconds. Top speed is electronically-limited to 155 mph. You can bet, faster AMG-models are also going to be offered shortly after this model goes on sale.
