Mercedes Benz has finally unveiled it’s new Mercedes-Benz model for the year 2012 & 2013. The SL 65 AMGRoadster comes with an output of 630 horsepower, each of the “biturbo” (or twin-turbocharged) 6-liter V12 engines were crafted by hand at the Mercedes-AMG facility. Clocked at 0 to 62 mph in just 4 seconds, the Mercedes-Benz SL 65 AMG takes the crown from the recently released SL 63 AMG as the top performance SL roadster in Mercedes-Benz’s inventory. To redefine the term “luxury performance”, Mercedes added Magic Sky Control, a panoramic vario-roof that is electro-hydraulically operated as an option. And like the previous SL, luxury features like AIRSCARF (air vents embedded seats), PARKTRONIC, Attention Assist, Bang & Olufsen BeoSound surround sound system, and more are all standard to the new SL 65 AMG. The car will be showcased at the New York Auto Show in April 2012 & it should be on the road by September 2012. As per sources, this beauty comes with a retail tag of US$ 312000.
