ATTRIBUTES OF THE EXCEL SYSTEM

motor braking.
• The Excel minimum motor braking speed has been lowered to almost zero.
• Excel has higher energy output during regenerative braking due to the lowered minimum motor braking speed.
• The Excel accelerator pedal has more control of downhill speed.
• When parked on a hill, the Excel vehicle resists sudden acceleration after the park brake is released.
• The programmed speed of the Excel vehicle can now range from 5 to 19.2 mph with fine adjustments in 0.1
mph increments.
