Optimal Electric Vehicles LLC

Optimal Electric Vehicles LLC (Optimal-EV) is entering the electric vehicle manufacturing with the introduction of its 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 a battery system, made in the U.S., 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.

Optimal Electric Vehicles LLC. is a derivative of Optimal Inc., an engineering firm serving automotive OEM’s as a preferred engineering service supplier for over 33 years. Optimal’s Engineering group has focused on EV and system design since 2015. The S1LF will debut at the APTA EXPO 2021, and the S1LF is the first of several planned commercial electric vehicles from Optimal-EV for use in a variety of applications.
