Imports led the majority of the government’s green car purchases last year, with 54 percent of the nearly 1,800 green vehicles purchased by the federal government coming from Hyundai, Toyota, Mitsubishi and Honda. The federal government’s most-purchased hybrid wasn’t a Big Three product either. Instead, it was the Hyundai Sonata Hybrid.

Sales of green vehicles were down for the third year in a row, while the almost-exclusively domestic fleet has grown to feature far more imports.

The GSA purchases in fiscal 2012 included 904 Sonata hybrids, followed by 372 Fusion hybrids, with General Motors Co.’s Chevrolet Volt plug-in electric model accounting for 163 purchases. The Sonata purchases represented 5.1 percent of the hybrid’s model’s U.S. sales for 2012.

The GSA purchased about 300 other hybrids from GM and Ford as well as five Toyota Prius hybrids and three of Mitsubishi’s i-MiEV electric car. The GSA also reported buying 49 Honda Civics powered by compressed natural gas that are built in Greensburg, Indiana.

The Korean-built Sonata Hybrid unseated the Ford Fusion Hybrid as the previous champion of federal fleet sales. But with a new Fusion Hybrid and the C-Max now available, 2013 could look different.
