Powertrain The Earth Dreams technology used on the Accord PHEV includes an i-VTEC 2.0-liter 4-cylinder Atkinson-cycle gasoline engine coupled with a two-motor hybrid drive system. The hybrid system features a 124-kW electric motor powered by a 6.7-kWh Li-Ion battery pack.
Although not finalized at press time, anticipated fuel economy ratings for the 2014 Accord PHEV are expected to exceed 100 MPG-e1 in full-electric mode, provide a 10- to 15-mile1 EV driving range and a calculated1 total driving range over 500 miles. When in gasoline-only mode, it is expected to return one of the top EPA fuel economy ratings among mid-size sedans, and is also expected to earn an Enhanced AT-PZEV rating from the California Air Resources Board (CARB).
The two-motor hybrid system in the 2014 Accord Plug-in Hybrid allows power from the gasoline engine to flow directly to the front wheels, power the generator to supply electrical propulsion or even charge the battery pack. The Accord PHEV hybrid system moves seamlessly and automatically through its three powertrain states to maximize performance, efficiency and range.
From a low-charge indicator point3, recharge time for the Li-Ion battery pack when plugged into a standard 120-volt wall outlet is less than three hours, among the fastest in the Accord PHEV's class. And when plugged into a Level-2, 240-volt charger the recharge time is less than one hour – the quickest in the class. This is about half the required charge time of the Prius Plug-In Hybrid. The battery pack is mounted above the rear suspension, which helps maintain interior and trunk space and provides protection for the battery pack in a collision.
