Mercedes SL65 AMG Black Series - official web page
Under the hood of the new SL 65 Black Series is a modified version of the 6.0-liter AMG V12 engine. It now delivers 650 horsepower and a staggering 738 pound-feet of torque. Its twin turbochargers are 12 percent larger, passages for intake air and the turbo wastegates have been modified, and the intake air intercooler is 30 percent more efficient. The result is zero-to-60 mph acceleration of only 3.8 seconds, and an electronically limited top speed of 198 mph.
