VII (Diesel)

The Orion Bus Industries Orion VII is a low floor transit bus that was available in Canada and the United States. The first production buses were built for Mississauga Transit in 2001.

Coincident with the introduction of EPA 2007 compliant engines, a restyled Orion VII was introduced in 2007. It features updated front and rear fascias and flush-mounted windows. The new model, called the Orion VII Next Generation, replaced the traditional Orion VII.


Unlike its predecessor the Orion VI, the Orion VII is not fully low floor and has a step up at the rear section of the bus. This compensates for the space lost to the rear wheels on the Orion VI. The bus's structure was built from either carbon steel or stainless steel and clad with fibreglass and aluminum panels.

The Orion VII was available in a conventional diesel, desiel-electric hybrid, or compressed natural gas (CNG) drivetrain. The engine is mounted longitudinally at the rear in a T-drive arrangement for conventional diesel and CNG-powered models. On hybrid models, the engine is placed transversely at the rear right side of the bus and is connected to the electric generator to the left. Diesel-powered models use a 125 gallon (473 litre) fuel tank placed under the high floor section. CNG-powered models have the fuel tanks housed in an enclosure on the roof. Hybrid models have their batteries in an enclosure on the roof.
