    First Take
    The luxurious SL is comfortable and quiet yet sporty, making it a delight to drive. This high-performance grand-touring roadster has a retractable hardtop. With the roof closed, it’s as quiet as a luxury sedan, and when open, wind buffeting is minimal. One slick feature is a roof panel that offers varying degrees of opacity. The SL is a comfortable cruiser yet doesn't shy away from spirited driving. The entry-level SL450's 3.0-liter twin-turbo V6 engine is mated to a nine-speed automatic. The next step up the SL ladder, the SL550, is powered by a 4.7-liter twin-turbo V8 that delivers smooth, effortless power. More powerful and expensive AMG versions are also available. Safety features include automatic emergency braking, blind spot warning, and lane keeping assist.
