Urban transport companies in Quebec and elsewhere in the world are showing a tendency to want to offer a more personalised, flexible and less polluting service. To do so, they need smaller, electrically-powered buses that can provide regular, low-density service during off-peak periods, with targeted capacity, for faster feeder service to intermodal stations, and that are accessible to people with reduced mobility. The present project aims to develop a new bus platform with a high Quebec content, medium-sized, 100% electric, designed in aluminium and with the particularity of offering greater accessibility to people in wheelchairs. Letenda is targeting the public transit, paratransit and private shuttle markets. By offering an uncompromising product that responds exactly to current demand, Letenda hopes to quickly distinguish itself from the competition. The concept aims to integrate functionalities for autonomous and semi-autonomous driving, a range of 300 km between recharges, a 100% low floor, 22 seated seats, 25 standing seats and 4 spaces for reduced mobility. Its targeted charging system is level 2 charging, so the vehicle will be recharged at night. The design will be thought out and conceived for industrialization, aiming at a reduced development time, low production and tooling costs and the use of standard structural materials. The expected results of this project are to obtain a functional prototype on a small dedicated circuit in order to validate its feasibility and performance. This research and development stage is crucial as it will allow Letenda to make its product known and to interest private investors and potential buyers in order to aim for the subsequent development stage of a demonstration vehicle.
