Toyota is lowering the price of the Prius plug-in hybrid.

The 2014 plug-in Prius will start at $30,800. That's $2,100 less than the 2013 model. Prices include an $810 shipping fee.

The 2014 model will also have some new features, including standard heated cloth seats.

The new pricing makes the plug-in Prius about $4,000 less than a Chevrolet Volt. Ford hasn't released pricing on the 2014 C-Max Energi, a close competitor of the Prius plug-in.

Plug-in cars can go further on an and get better gas mileage than regular hybrids. But sales have been sluggish because of stable gas prices and the vehicles' higher prices. A plug-in Prius costs about $5,000 more than a regular one.

Just 4 percent of Prius sales this year have been plug-ins.
