PepsiCo's Frito-Lay North America division will begin rolling out fully-electric delivery trucks in New York.

The company plans to deploy 21 electric trucks this year and projects it will roll out 155 more trucks in 2011, making it the largest commercial fleet of all-electric trucks in North America.

The trucks have been designed by Smith Electric Vehicles to generate zero tailpipe emissions and operate for up to 100 miles on a single charge.

"Frito-Lay has implemented bold goals for reducing our use of key resources such as fuel to ultimately help us reduce our overall environmental impact," said Mike O'Connell, director of fleet capability for Frito Lay North America. "There are real economic and environmental benefits to electric trucks. Once the planned 176 electric trucks are deployed we will eliminate the need for 500,000 gallons of fuel annually. Each truck emits 75% less greenhouse gases than a conventional diesel truck."
