2010 LA: Honda unveils plug-in hybrid system for mid-size sedan due in 2012

Alongside the Fit EV prototype, which will hit the U.S. and Japanese markets in 2012, Honda unveiled a plug-in hybrid platform that showcases Honda’s next-generation, two-motor hybrid technology also set to debut in 2012.

“Integrated into a mid-size sedan platform, the plug-in hybrid is designed to be compatible with daily driving habits, allowing for short, frequent trips in all-electric mode, while providing long-distance driving capability when needed,” Honda said. “The Honda two-motor system continuously moves through three different modes to maximize driving efficiency: all-electric, gasoline-electric and a unique, engine direct-drive mode. The plug-in hybrid also uses regenerative braking to charge the battery.”

In all-electric mode, the mid-size sedan uses a 6kWh lithium-ion battery and a powerful 120 kW electric motor. How many miles can you go in all-electric mode? 10-15 miles in city driving at a top speed of 62 mph. Reaching full charge takes 2 to 2.5 hours using a 120-volt outlet and 1 to 1.5 hours using a 240-volt outlet.

After the battery has depleted the mid-size sedan can run in a gasoline-electric hybrid mode, which is assisted by 2.0L, i-VTEC inline 4-cylinder, Atkinson cycle engine, paired with an electric Continuously Variable Transmission (E-CVT). An onboard generator adds to the battery powering the electric motor.

However, if you’re involved in a high-speed change the vehicle can turn into direct-drive mode, in which only the engine drives the front wheels.
