The official car of summer has arrived. Based heavily on its hard-topped sibling, the 2012 Mercedes-Benz SLS AMG Roadster ($TBA) sets a new standard for Mercedes convertibles. Thanks to its 6.3-liter V8 AMG front-mid engine and seven-speed dual clutch transaxle transmission, the Roadster boasts 563 hp, a zero-60 time of just 3.7 seconds, and a top speed of 197 mph — electronically limited, of course. Other features include a compact fabric top that can open or close in just eleven seconds, a Bang & Olufsen BeoSound AMG high-end sound system, Active AMG Sport Suspension, an AMG Performance Media system, and an AMG Drive Unit. Sunny weather and happily deserted roads not included.
