It’s the eve of press days at the Detroit Auto Show, and Mercedes-Benz has kicked off the week in fine style with the premiere of its 2013 SL. While the 60-year-old franchise has periodically undergone radical revisions, the sixth-generation should look familiar to anyone who has seen the outgoing model, but that doesn’t mean that Benz hasn’t tugged and pulled the SL every which way. While the general form looks very similar to the fifth-generation roadster, there are subtle tweaks everywhere, the most noticeable being the eagle’s-eye LED daytime running lamps.
As before, the two-seat roadster relies on a power folding hardtop, though the folding roof can now be had with Magic Sky Control, the trick bit of electrochromatic glass with variable opacity first offered on the SLK. The original SL nomenclature stood for Sport and Lightweight, but in recent years, the latter descriptor hasn’t really applied to the big coupe. The 2013 model seeks to reclaim some of that featheriness with a new all-aluminum structure and body, and Mercedes says the new SL550 weighs about 275 pounds less than the exiting model.
Powered by Mercedes’ 4.6-liter twin-turbo V8, the SL550 delivers 429 horsepower at 5,250 rpm and a whopping 516 pound-feet of torque from 1,800 rpm. As before, that power is routed through a seven-speed auto to the rear wheels. Apart from its lightweight aluminum construction and downsized engine, Mercedes has made a few other concessions to greener motoring including standard stop/start. Despite this, the 32-percent swell in torque and 12-percent bump in horsepower means that 60 miles per hour hits in just 4.5 seconds – the old car required 5.2 seconds. Top speed is limited to 130 mph, and judging from the engine, it sounds like you’ll be able to say hello to the governor rather quickly.
Over the years, Mercedes has made many contributions to the art of year-round top-down motoring, with items like heated seats, HVAC systems with dedicated top-down modes, Airscarf, and so on. For 2013, the SL gains a new wiper blade system dubbed Magic Vision Control that streams wiper fluid along the blade to avoid overspray into the interior when the top is dropped. The entire wiper is heated as well.
The model seen here is the limited edition “Edition 1” launch specification, which wears 19-inch AMG alloys, Designo leather, Airscarf, Harmon Kardon surround audio and available Designo crystal silver magno paintwork. We should know a bit more about pricing before the car arrives in dealers this spring.
