Mercedes-Benz will be dropping their V12 SL-Class models, the SL65 AMG and SL600, from its 2012 line-up. The move comes as the automaker prepares for the introduction of the redesigned 2013 SL-Class towards the end of next year. Under the hood of the current SL600, power comes from a twin-turbocharged 5.5-liter V12 producing an output of 510hp and 610 lb-ft of torque, while the SL65 AMG draws its power from a twin-turbocharged 6.0-liter V12 churning out 604hp and 740 lb-ft.

Like many other automakers, it's clear that Mercedes-Benz is in favor of using more fuel efficient V8 units instead of the heavier and thirstier V12s. And like their German rival, BMW, we shouldn't expect performance to suffer. A good example of this is the new BMW M5 which is now powered by a twin-turbo V8 with 560hp instead of a V10 with 500hp as in the previous generation.
