A new report from Green Car Reports says Mercedes-Benz is planning to launch three plug-in hybrid models by 2016 or so. We know two of those models have been confirmed. The first is a S-Class Plug-In Hybrid due out next spring. The model will utilize a turbocharged 3.0L V6 gas engine and a 80 kW electric motor. Following the S-Class will be the C-Class plug-in hybrid in the fall.
The third model is reportedly the ML-Class. The model is expected to get a refresh for the 2016 model year and a plug-in variant is expected in the refresh. It is expected to arrive around the same time as the C-Class.
