2014 Mercedes-Benz S-Class
The car’s dimensions change very little from its predecessor. The wheelbase and length are the same, while interior space is up marginally in all directions. The engine in the S550 remains a twin-turbocharged 4.7-liter V-8. Horsepower rises by 26 to 455 total, while torque remains unchanged at 516 pound-feet.
The 2014 S550 hits 60 mph in a Mercedes-estimated 4.8 seconds, down from the outgoing all-wheel-drive S550’s estimated time of 5.4 seconds.
