DRIVING THE INDUSTRY SINCE 1991
Mike Taylor, Cummins’ director of cus-
tomer engineering and business develop- ment, said fans of the ISB6.7L should not be worried. “Certain segments value and love the ISB 6.7, so we’re not trying to displace it,” he said. “We are, though, looking to offer something new, the lighter side of that space, perhaps for a smaller bus.” While diesel remains the prevailing mar-
ket share by leaps and bounds, he pointed out that some school bus operators do use gasoline-powered buses, so the ISV5.0 will be able to replace those and offer a new range of a light, compact engine. Cummins is planning to go into commer-

In the meantime, the company has essentially 12 months to up fit the Cummins Engine Plant in Columbus, where the ISX was born, before moving fully to Jamestown, N.Y., where the company continues to manufacture the ISB. Te ISV5.0 warranty for school buses is five years or 100,000 miles.
Taylor added that Cummins is working
with “all kinds of OEMs” to prepare for taking orders. While IC Bus, Tomas Built Buses
and Collins Bus Corporation declined to comment for this article, Blue Bird said it is continuously evaluating new innovations to make its buses better. Spokeswoman Erin Lake confirmed that the company has an active product development program in conjunction with Cummins to determine the suitability of this new engine for Blue Bird school bus application. “Power, torque, fuel economy, drivability,
durability, serviceability and the cost of this new powertrain are being evaluated by Blue Bird to help determine if this engine should be added to its lineup,” she added. “Blue Bird is always on the leading edge of product innovation, and works closely with suppliers such as Cummins to take our product to the next level.” “Te ISV5.0 concept was born in the late 1990s during a research project funded by the U.S. Department of Energy.
