Think of that savings as over $11,000 per cylinder, as the SL400 foregoes V8 power in favor of a 3.0-liter, twin-turbo V6 with 329 horsepower and 354 pound-feet of torque and seven-speed automatic rated at 20 miles per gallon city and 27 mpg highway. Those numbers are roughly 100 hp and 160 lb-ft less than the SL550. Still, the new model can get to 60 miles per hour in a quick 5.1 seconds, compared to 4.5 for the its big brother.
Thankfully, buyers don't have to give up the optional luxuries that makes the SL special to get the cheaper model. The Air Scarf comes as part of the $4,900 Premium Package, Distronic adaptive cruise control is available as part of the $2,950 Driver Assistance Package and Benz's clever dimming Magic Sky Control roof is a separate option for $2,500. If the idea of a Mercedes-branded folding hardtop convertible that gives up a little power for a lot less money sounds good to you, then you're thinking like we are.
