The propulsion system is an electric motor powered by an energy storage device driving a speed reduction and differential with dual outputs suitable for two wheel front drive. The operator's seat is narrower in parts than a conventional automotive seat such that the rear seat passenger's knees can comfortably straddle the operator seat to allow the distance between the two occupants to be less than a typical automobile. The driver's and passenger's heels comfortably fit into recessed wells within the energy storage device, thus allowing the driver's and passenger's center of gravity to be lower, while still maintaining a comfortable sitting position.
