Optimal Electric Vehicles, LLC (Optimal-EV) has announced this month that it will enter vehicle manufacturing and its first product will be an all-electric S1LF Low-Floor Shuttle Bus, built on the Ford E450 chassis platform.
This new model will be unveiled at the APTA EXPO 2021 and be available for commercial purchase in 2021.
"The S1LF integrates a quasi-purpose-built Ford E450 chassis platform, which has been fully optimized with the vehicle body and achieves a low step-in height without kneeling the suspension. The all-electric S1LF will feature an ADA compliant entry ramp for paratransit operations and a gross vehicle weight rating (GVWR) of 14,500 lbs., with no reduction in carrying capacity."
To jump-start the project and lower costs, Optimal-EV teamed with electric bus manufacturer Proterra, who will supply battery and charging system. The 113 kWh battery is expected to provide more than 125 miles (201 km) of range.
The long-term plan includes "several" commercial electric vehicles "for use in a variety of applications".
Optimal-EV S1LF Low-Floor Shuttle Bus specs:

Optimal Electric Vehicles, LLC. (Optimal-EV) enters electric vehicle manufacturing, with their battery electric S1LF Low-Floor Shuttle Bus. The S1LF integrates a quasi-purpose-built Ford E450 chassis platform, which has been fully optimized with the vehicle body and achieves a low step-in height without kneeling the suspension. The all-electric S1LF will feature an ADA compliant entry ramp for paratransit operations and a gross vehicle weight rating (GVWR) of 14,500 lbs., with no reduction in carrying capacity.
The S1LF will feature an efficient and powerful battery system, made right here in the USA, featuring 113 kWh of liquid-cooled energy capacity, fueling an all-electric, zero-emission rear-axle drive system. The vehicle is designed to enable more than 125 miles of driving range and can fully charge in about two hours with optional DC fast charging. The S1LF is only available as a pure battery electric bus.
