Top 10 Most Powerful Sedans

1. Mercedes-Benz S65 AMG - 621 HP

The new king on the block is the recently announced 2015 Mercedes-Benz S65 AMG. Though it’s not yet on sale and is still listed as a future vehicle from the German automaker, we do know that it’ll have a 6.0-liter V12 twin-turbo engine with 621 hp and 738 lb-ft of torque. It almost comes as no surprise that Mercedes wants to reign supreme in the power department when it comes to its flagship sedan, especially collaborating with its AMG division. No pricing or fuel economy figures have been announced yet, but if you’re looking for sheer power, luxury and space, you might want to add your name to the waiting list.
