The 2015 Mercedes-Benz S65 AMG is one of the fastest and most luxurious sedans on the market. German host Sarah Sauer decided to take one for a spin and spend a day living in the lap of luxury. The Mercedes-Benz S65 AMG is powered by a 6.0 liter twin-turbo V12 engine making 621-hp and 732 kb-ft of torque. 0 to 60 mph comes in at 4.2 seconds! Now that's some serious asphalt-grinding power. :) A fun automobile, or unnecessary overkill? We'll let you be the judge.
