Chronology
Predecessor

The Orion VII is a line of

DaimlerChrysler
withdrew from the transit bus market in 2013.

Design

The two-piece windshield of the original Orion VII has the driver's windshield canted towards the back of the bus to reduce reflections; the second and third generations also had a two-piece windshield, but both panes are curved similarly and collectively resemble a single piece. Externally, the three generations may also be distinguished by the position of the top of the doors. In the original Orion VII, the top of both the front and rear doors is at the same level as the top of the side windows. In the Orion VII Next Generation (VIING), the top of the front door is at the level as the bottom of the standee windows. In the Orion VII EPA10, the tops of both doors are at the height of the bottom of the standee windows.

The Orion VII uses a monocoque stainless steel frame clad with aluminum and fiberglass panels.[2] The interior floor height is 15.5 inches (390 mm)[1] except for the portion starting at the rear wheels, which is elevated to provide mechanical clearance for the engine and transmission. All conventional (diesel/CNG) buses use longitudinally-mounted engines with a T-drive transmission coupling driving the rear axle.

Series Hybrid

New York City Transit since 2002, had per-mile maintenance costs comparable to CNG-fueled buses, with improved overall operating costs per mile mainly due to better fuel economy (3.00 to 3.22 mpg‑US (0.78 to 0.73 L/km) for the hybrids evaluated, compared to 2.33 mpg‑US (1.01 L/km) diesel equivalent for the CNG buses).[12] In 2008, it was reported that Toronto Transit Commission's Orion hybrid bus fleet suffered from early failure of lead-acid batteries in roof-mounted battery pack and much lower fuel savings than expected.[13][14][15]

Allison Hybrid

Orion announced the Allison Hybrid H 40 EP two-mode parallel/series hybrid system would be offered starting in 2011.[16] A demonstration unit with this powertrain was delivered to DART.

Deployment

The first operator of the Orion VII was Mississauga Transit (MiWay) for the first 14 production models powered by the Detroit Diesel Series 50 diesel engine. These buses were retired in 2013. MiWay also ordered 15 hybrid models and 35 diesel BRT models in 2010 and 2012, both of which are EPA10 models.

Although New York City had previously evaluated ten Orion VI and five NovaBus RTS buses[17] equipped with series hybrid propulsion as a small pilot program starting in 1998,[18] the first major deployment of hybrid buses were the 125 Orion VII HybriDrive buses ordered in 2001/02.[19]

In 2013, New York MTA announced plans to convert approximately 1⁄4 of their hybrid fleet to solely conventional diesel power;[20] after the warranty expired, the agency was not willing to bear the cost of traction motor replacement.[21] However, only two buses, both now retired have been converted.

The Toronto Transit Commission is another notable operator of the Orion VII, having purchased buses in both diesel and series hybrid diesel-electric propulsion configurations between 2002 and 2012. As of 2024, the Orion VII buses remain in service and maintained at Arrow Road, Malvern, Mount Dennis, Queensway and Wilson garages. At 879 diesel buses ordered, they were the largest operator of Orion VII diesel buses in North America.

The San Francisco Municipal Railway (SF Muni) announced the acquisition of 86 series hybrid Orion VII buses in 2004, delivered in the last half of 2007;[22][23] however, the hybrid buses proved to be unreliable.[20]

Two Orion VII Hybrids are also operated by the

Edmonton Transit System
. Both buses were built in 2006.
