New Flyer, the leading manufacturer of heavy-duty buses inthe U.S. and Canada, has been building CNG buses since 1994, and in December of 2011, delivered its 4,000th CNG bus. New Flyer CNG buses offer many benefits not available from other bus manufacturers. New Flyer’s CNG system is specifically designed for New Flyer buses; it is not purchasedfrom another supplier, which means it is part of the overall design and not an add-on. New Flyer is the only manufacturer to exceed today’s CNG standards and safety requirements.
