From an article in The Daily Reporter:

Milwaukee County’s vehicle fleet is becoming more fuel-efficient, thanks to an infusion of Ford Fusion Hybrid vehicles unveiled Monday at Milwaukee County’s Fleet Maintenance facility.

The vehicles will replace 35 aging Chevy Impalas currently used in a variety of county departments that were driven a total of 332,500 miles and cost nearly $40,000 in fuel annually, according to a news release from acting Milwaukee County Executive Lee Holloway.

The new hybrid vehicles are estimated to cost $26,000 in fuel annually — a 35 percent fuel savings – and will save more than 4,400 gallons of petroleum per year, according to the release.
