The 2016 Mercedes-Benz S550 plug-in hybrid luxury sedan will join the automaker's growing lineup of gasoline-electric hybrids and battery-electric vehicles when it arrives in April of 2015.
The S550 plug-in hybrid will become the fourth such vehicle offered by Mercedes-Benz in the U.S., following the E400 hybrid, smart electric drive, and B-Class Electric Drive. The B-Class arrived earlier this year.
