LISLE, Ill. – November 15, 2017 – IC Bus recently completed an order of CE Series propane-powered school buses by Cook-Illinois Corporation, the largest family owned and operated school bus contractor in the United States – and the sixth largest among all school bus companies nationwide.

“As a leader in developing alternative powertrain solutions for the school bus industry, we are excited to introduce our propane-powered CE Series school buses to the Cook-Illinois Corporation fleet of nearly 2,700 vehicles,” said Trish Reed, vice president and general manager, IC Bus. “Cook-Illinois Corporation is a prominent school bus operator that has moved from diesel-powered school buses to focus on providing greener transportation services to its customers. We’re proud to partner with Cook-Illinois Corporation in supplying an environmentally friendly, reliable and safe solution powered by the Power Solutions International (PSI) 8.8 liter LP propane engine.”

Purpose-built for the school bus industry, the CE Series with PSI propane engine is designed to provide diesel-like performance with higher torque at lower engine speeds. The high torque-low speed design greatly benefits stop-and-start applications to allow immediate acceleration after stops and greater hill climbing capability. This not only improves startability and gradability, but also eliminates excessive noise, heat and vibration associated with constant engine revving. Minimal revving reduces engine wear, oil usage and maintenance, while increasing durability and efficiency.

"We are a pioneer in ‘green fleet’ efforts in the state of Illinois,” said John Benish, Jr., president and chief operating officer, Cook-Illinois Corporation. “We are pleased to add these IC Buses with propane engines and equipped with hydraulic brakes to our fleet to help our customers transport their students to school safely, on time and ready to learn."
