Our 2019 Mercedes-Benz S-Class S 450, shown in extraordinary Diamond White Metallic, moves you with sophistication and accomplishment. S 450 contains a marvelous twin-turbo 3.0-liter V-6 that whips up 362 horsepower and 369 pound-feet of torque. With its smooth-shifting 9-speed automatic transmission, the S 450 can reach 60 mph in 5 seconds or less, according to Mercedes-Benz. As much as almost any other vehicle on the market, Mercedes-Benz's full-size S-Class flagship represents the pinnacle of luxury. Harmonious body lines cut an especially attractive outline in cabriolet form. Sedans lead off with a wide, slatted grille, while convertible grills feature vertical ribs with an LED-illuminated three-pointed-star logo. Viewed in profile, the S-Class blends a degree of formality with an athletic stance, punctuated by numerous eye-grabbing details. As expected from an automobile in this league, plenty of safety features are standard. They include automatic emergency braking, blind-spot monitors, and adaptive cruise control. Safety options include night vision and a surround-view camera system.
