XL provides hybrid electric school buses with 25 percent higher MPG and 20 percent lower CO2 emissions

BOSTON, April (12), 2018 – XL, the leader in connected vehicle electrification solutions for commercial and municipal fleets, recently completed a successful pilot deployment of hybrid electric school buses with Careful Bus Company in New York City, the company announced today. The XLH system is a unique technology that uses regenerative braking during deceleration and electric assist during acceleration to increase fuel economy. The system, which was installed on five of the company’s standard Ford E-Series vehicles in just a few hours, is expected to increase miles driven per gallon by 25 percent and improve brake life, while decreasing CO2 emissions by 20 percent. Using the XL fleet electrification technology, Careful Bus can reduce its carbon footprint and support New York City’s larger sustainability goals.

New York City and other urban municipalities are innovating and adopting new technology to reduce carbon footprints despite unique challenges presented by stop-and-go traffic, dense populations and weather extremes. Careful Bus, which operates a fleet of about 100 student transportation vehicles as part of a contract with the New York City Department of Education, has been an early adopter of many innovative transportation technologies over its 45-year history, including GPS technology, dashboard cameras and thumb scanner equipment. Today, the new hybrid gas/electric school buses are a natural fit for the company’s commitment to clean energy and the city’s ongoing initiatives to reduce emissions and fossil fuel reliance, and Careful Bus plans to dedicate 5-10 percent of its fleet bus purchases to XL hybrid electric vehicles each year moving forward.     

"We are always testing the newest technology to find ways to reduce our carbon footprint; however, even if all new school buses are available in a full-electric manner within a few years, everyone still needs a stepping stone to help the vehicles on the road in New York City tomorrow,” said Marty Hoffman, co-owner of Careful Bus. “XL's regenerative braking energy and hybrid electrification technology really shines in New York’s environment – there's a lot of stop-and-go driving, which can take a toll on fuel usage and brake life. Since working with XL, our maintenance team has noticed significantly extended brake lifespans, our drivers have all positive feedback on the added boost during acceleration, and we've reduced fuel usage, too."

In addition to the Careful Bus deployment, XL provides hybrid electric (HEV) and plug-in hybrid electric (PHEV) vehicle systems to municipal fleets across the U.S., which rely on XL’s technology to green vehicles without the extra cost of building additional charging infrastructure. XL also recently received New York State Department of Transportation’s (NYS DOT) approval for both Ford and General Motors HEV shuttle buses and school buses, and has electrified several other fleets within the New York jurisdiction.

"Municipal fleets like Careful Bus recognize the huge opportunity they have to make sound environmental and financial decisions, and New York has been a leading influence among U.S. cities for their commitment to green energy,” said Clay Siegert, co-founder and chief operating officer of XL. In fact, New York has committed to honoring the ‘1.5⁰ C plan’ that was outlined in the Paris Agreement, which sets a goal of limiting global warming increases to 1.5⁰ C. “Electrified vehicles represent an important and growing part of a sustainable future,” he added.
