What in Lin’s name are you gonna do with 738 pound-feet of torque? Figure that out later. For now focus on how you’re gonna score a 2013 Mercedes-Benz SL65 AMG. Packed with a twin-turbocharged 6.0-liter V12 that generates 621 horsepower and yes, that insane torque, the SL65 AMG’s all-aluminum body means it’s a couple of hundred pounds lighter than last year’s model. Look for the debut of this rocket roadster at next month’s New York Auto Show, and in the meantime, start thinking about what you’re gonna do with all that torque.
