Toronto Transit Commission 1700-1829 (Orion VII NG HEV)

Manufacturer: Orion Bus Industries
Model: Orion VII NG HEV 07.501
Engine: Cummins ISB
Transmission: BAE Systems HybriDrive

1700-1829 were delivered in 2009.

They came pre-equipped with Lithium-Ion batteries, unlike the two earlier deliveries. Currently this is the last order of hybrids the TTC is purchasing; all further deliveries are expected to be regular diesel buses.

Retirements:

Mount Dennis: 1991 Orion V (6640-6745), GM New Look
Wilson: GM New Look

Division Histories:

Malvern: Malvern was the first division to accept deliveries. They mainly displaced the 1200-1423 series to Arrow.
Wilson: Wilson started accepting this series halfway through delivery. This allowed most of the remaining 14xx to go to Arrow and much of the 1500-1689 series to Mount Dennis.

Recommended Sightings: 85, 95, 133, 134
Although they may appear on any route at Malvern or Wilson, the 17xx series make up comparatively more of Malvern's LF roster and therefore they are easier to find on any Malvern LF route.
