Honda replaced the hood and rear bumper with aluminum parts, and used an aluminum front subframe to help reduce weight. Aerodynamics are aided by flat underbody pans. As with the standard Accord, the Accord Plug-in Hybrid is front-wheel-drive.

Although the body features few changes from the standard Accord, the grille treatment is different. The badge and a big chrome bar, accentuated with blue inserts, run between the headlights. The air intake drops lower than on the standard Accord, and has a honeycomb grille.

LED headlights and running lights come standard on the Accord Plug-in Hybrid as a means of reducing electricity usage.

Because of the new hybrid system, Honda was able to significantly downsize the gas engine from a 2.4-liter in the standard Accord to a 137-horsepower 2-liter Atkinson cycle engine in the plug-in hybrid. A continuously variable transmission incorporates a 124-kilowatt electric motor, which can drive the car under pure electric power for 10 to 15 miles. Honda rates the total drive system output at 196 horsepower.

A plug-in port sits on the left front fender. Honda projects the electric drive efficiency at over 100 miles per gallon equivalent, although the combined gas-electric EPA rating is likely to be much less. With a 240-volt source, recharge times are less than an hour. The charging time goes up to 3 hours for a 110-volt source.

Honda placed the 6.7 kilowatt-hour lithium ion battery pack behind the rear seats. As such, it intrudes substantially into the trunk area, and prevents any pass-through from rear seats to trunk.

The Accord Plug-in Hybrid will only come in one trim level, equivalent to a high-trim gasoline-engine Accord. As such, it will come standard with a hard-drive-based navigation system and feature the new EV version of the HondaLink system, which lets owners use a smartphone app to schedule charging.

The instrumenter is tailored to the car's EV operation, with a power meter to the left of the speedometer.

Honda stores a 110-volt adapter cable under the floor of the trunk, making it easy to plug in the Accord just about anywhere.

Honda has partnered with Leviton for charging stations. Owners will be able to get charging stations installed in their garages, although with the quick charge times for the Accord Plug-in Hybrid, it will probably not be necessary for most people.
