" Well, at least its passenger cabin is open for all to see now that Mercedes-Benz has revealed photos of the new roadster version of its SLR supercar by McLaren.   Mercedes promises that the conversion to open-air driving will in no way compromise the performance of its almighty 2-seater, which is powered by a 617-bhp supercharged 5.5-liter AMG V-8, which the company says is good for a top speed of a blistering 207 mph. The engine produces 575 lb.-ft. of torque and is mated to a 5-speed automatic transmission. The SLR is capable of 0-60-mph acceleration in 3.8 seconds.   The SLR retains its carbon-fiber body, while the retractable hardtop is a hybrid of carbon fiber and aluminum. Even without its roof, the SLR&amp;#039;s doors open up and forward, butterfly style. The top itself is a semiautomatic affair; it must be manually unlatched from the windshield header and pushed up slightly where the power mechanism kicks in and stows the lid in less than 10 sec. beneath the aluminum forward portion of the roof, which also serves as a closeout panel for the retracted top.   In addition to the standard array of safety equipment that includes knee and side airbags, the Roadster is also equipped with two fixed rollbars behind the bucket seats.   U.S. delivery of the SLR Roadster is expected to begin this fall. Price has yet to be announced. "^^<http://www.w3.org/2001/XMLSchema#string>
