Optimal-EV and Proterra, a manufacturer of heavy-duty electric transit technologies, have announced a partnership to leverage Proterra’s battery technology and charging systems for the development of the first all-electric S1LF low-floor cutaway shuttle bus for the North American market.
The Proterra battery system powering the S1LF will feature 113kWh of energy capacity and an all-electric, zero-emission drive system designed to enable more than 125 miles of driving range. The vehicle can fully charge in about two hours with optional DC fast charging.
The all-electric S1LF integrates a Ford E450 chassis platform, which has been fully optimised for the vehicle body. It will feature a gross vehicle weight rating of 14,500 lb, with no reduction in carrying capacity.
Dan Daniels, COO, Optimal-EV, said: “Electric vehicles offer a smoother, quieter rider experience while producing zero tailpipe emissions for improved air quality and public health. Optimal is expanding the accessibility of EV technology to more riders by introducing the industry’s first all-electric low-floor shuttle bus. Proterra’s expertise and experience in battery-electric transit buses makes them an ideal and trusted partner as we design and deliver this new vehicle.”
Optimal’s low-floor design, which is made possible by the packaging of battery-electric propulsion, allows for ultra-low 11-inch step-in height and quick deployment of an ADA-compliant accessibility ramp without the need for kneeling suspension.
The S1LF wil be available for commercial purchase in 2021. It is the first of several planned commercial EVs from Optimal-EV for use in a variety of applications.
