Earth Dreams Engine
The all-new engine that powers the Accord Plug-In has driven us to the forefront of automotive and environmental technology: the 2-liter, 4-cylinder Earth Dreams engine. It's responsible for the Accord Plug-In's incredibly efficient torque regulation and fuel combustion, and it helps the Plug-In obtain, mpg ratings that reinforce our reputation as an environmental leader.
