About Us

Fleet Electrification Leader

When XL Fleet was founded (as XL Hybrids) back in 2009, the green transportation market looked very different than it does today.  The average price of gas in the US was $1.84/gallon (diesel was $2.27) and electrification for fleet vehicles was in its infancy.  In fact, very few of the companies selling hybrids, plug-in hybrids, or all-electric fleet vehicles in 2009 are still around today.

Founded by MIT alumni and green energy veterans, the company was on a mission to provide simple, sustainable electrification solutions to the commercial fleet market – a previously untapped space with a large number of vehicles with low mileage and high emissions.

Over one decade and more than 180 million customer miles later, that mission continues. XL Fleet has become the undisputed leader in fleet electrification solutions for Class 2-6 commercial and municipal vehicles. With thousands of XL-equipped vehicles on the road, we have helped save our customers well over 3 million gallons of fuel and eliminated over 26,000 metric tons of CO2 emissions from the atmosphere.

Best of all, we’re just getting started. We hope you’ll be part of our next decade of success, as we continue our mission to help our fleet customers save money, improve driver productivity and make a positive impact on our environment and the world around us.

XL at a Glance: Driving Fleet Sustainability
  • Industry leader in electrification for Class 2-6 commercial fleet vehicles

  • Strong partnerships with major OEMs (Ford, GM, Isuzu)

  • Substantial savings in fuel costs and greenhouse gas emissions
