Mercedes-Benz takes the top off the SLS and lets the sun shine in. The same great drivetrain and suspension is now topped with a fully automatic retractable canvas roof with solid rear glass. The top goes up or down in 11 seconds and can even be operated at speeds up to 31 mph, so you don't have to block traffic when the sun comes out all of a sudden.
Since the SLS was designed from the outset to accommodate a soft top, additional structural reinforcements were limited to slight modifications of the door sills and some cross-bracing, all of which added only 4.4 pounds to the body-in-white. Total weight increase for the roadster version was only 88 pounds. Total increase in fun was considerably more.
Is there a better grand tourer made today? Seriously, if you had to--say someone forced you--to drive the greatest roads of, say, Europe, all of the greatest roads, well, OK, then you'd have about a million choices for which car to take. But if you wanted to take someone along and you wanted that person to be comfortable and, indeed, you wanted a high level of comfort to go with your high-speed Alpine Pass-crossings, the list of cars to do it in shrinks a bit. After careful consideration you might find the SLS Roadster on top of the list.
The powertrain is unchanged from the coupe. The 6.2-liter V8 still makes 571 hp at 6,800 rpm and 480 lb-ft of torque, and it still sounds great doing it. The difference is you can now hear that wonderful thunderous cacophony much better with the top down. Blasting through the many tunnels of the Alpes Maritimes we pulled the "down" paddle on the left side of the steering wheel just to hear the sound of the pipes echoing off the cool limestone.
Our drive route took us from the Grand Prix course in the streets of Monaco--specifically through the start/finish, the bus-stop chicane and through the tunnel--to long winding stretches of the Rallye Monte Carlo through Sospel. In the city and along the beaches of the Cote d'Azure with the top down, the SLS Roadster was perfect for communing with the beach community. The SLS behaves perfectly smoothly in stop-and-go traffic and could easily function as a daily driver. Once up in the hills we could set the transmission and suspension to whatever was appropriate for mountain pursuit driving. The transmission can go from normal to sport and sport-plus depending on your mood and there is a new feature, to be shared with the coupe, that allows for three stiffness settings for the suspension. And, thankfully, there is a "traction off" button, which we employed for the many hairpin switchbacks. The power of the car was easy to lay down onto the roads, and the stability of the SLS Roadster, just as in the coupe, is amazing. We never got into any trouble despite roads that would eat lesser cars for lunch.
In a straight line, 0 to 60 mph comes up in 3.6 seconds and top speed is 197 mph. We didn't try the top speed but we believe the car is quite capable of that.
There are more competent sports cars that could negotiate a racetrack faster than this and provide more immediate, direct feedback to your sitzplatz, but the SLS Roadster is a car that you could live with spending a summer crisscrossing every pass in the Alps just as easily as crossing every intersection in Paris (or Peoria).
Of course, it ain't cheap. Mercedes says pricing will be "under $200,000" when cars begin arriving in dealerships in early November.
