Nova Bus LFS HEV
|Years of manufacture||2006 to present|
The Nova Bus LFS HEV is a diesel electric hybrid version of the Nova Bus LFS. It was launched at the 2006 CUTA Trans-Expo in Toronto, with the first examples going to the Société de transport de l'Outaouais at the beginning of 2007.
When launched, the LFS HEV used a parallel hybrid supplied by Allison. The standard 8.9 litre Cummins ISL engine, used on on the standard LFS, drove the wheels in combination with an electric motor. Beginning with Coast Mountain Bus Company's 2009 order, the LFS HEV was offered with the 6.7 litre Cummins ISB engine. It was reasoned that fuel savings would be maximized with the smaller engine if the buses were operated in appropriate conditions.
The Association du transport urbain du Québec, representing nine public transit agencies in the province, placed an order for hybrid buses in 2013. They specified a series hybrid system which was supplied by BAE Systems. In this configuration, the Cummins ISB engine acts as a generator and an electric motor powers the wheels directly. The series hybrid option has since become an option.
In the summer of 2017, the Société de transport de Laval introduced two plug-in hybrid buses for an 18-month trial. The two LFS HEV buses, built in 2016, were fitted with a Euro 2019 Cummins B4.5 diesel engine connected to a TM4 SUMO HP HV900 electric generator with a TM4 SUMO HD electric motor driving the rear axle. The buses are also equipped with 111-kilowatt-hour lithium ion batteries and a current collector. They can be quickly recharged in 10 minutes en route with a 450-kilowatt charging station and operate in all-electric mode for longer distances (up to 35 kilometres). The project received $4.25 million from the Green Fund, under the Technoclimat program.
In 2018, the option for an electrically-driven HVAC system (the MCC Eco 136E) was introduced. The Toronto Transit Commission was the first customer to specify this option. Because the electric HVAC is the same height as the battery compartment, buses with this option feature the LFX-style full roofline, though the STM has chosen to specify the previously-used partial roofline on the latter half of their 2020 order.
