GE is buying 2,000 C-Max Energi plug-in hybrids from Ford Motor, as part of an effort to convert half of its global fleet to alternative fuel vehicles.

The purchase gives GE 5,000 alternative-fuel vehicles. Its goal is to reach 25,000.

As part of the agreement, Ford is promoting GE’s electric charging stations, including the WattStation charging station and CNG in a Box natural gas fueling station.

“At GE, we are focused on providing our customers and our fleet with more economically and environmentally efficient vehicles,” says Mark Vachon, vice president of ecoimagination at GE, according to CBS Detroit. “The Ford C-Max Energi plug-in hybrid is a great addition to our expanding fleet of alternative fuel vehicles."

The two companies will also work with Georgia Tech researchers to study GE employee driving and charging habits. The studies will be shared with other companies who plan to add electric vehicles to their fleet.
