XL Hybrids, Inc. is beginning production of hybrid-electric F-250 Super Duty pickup trucks this month, the company announced. This will be the first time that Ford F-250 trucks can be ordered by fleet customers with hybrid-electric technology.

According to the company, upfitting the 2018 Ford F-250 with the XLH hybrid electric system can lead to as much as a 25% improvement in fuel efficiency, along with accompanying reductions in CO2 emissions. XL is also making more F-150 models available with hybrid-electric upfits, including SuperCrews.

“Ford trucks are in high demand by XL’s fleet customers, so we developed our hybrid-electric upfit solutions for both the F-150 and F-250 pickup to support needs for power, payload, as well as better fuel economy,” said Clay Siegert, chief operating officer for XL. “We recently surpassed a landmark 60 million total combined customer road miles, and our experience in successfully supporting leading fleets informs our product roadmap. We continue to be focused on delivering the most seamless, cost-effective fleet electrification solutions for OEM vehicles that our customers ask for.”
