Data for two 50-h motors are follows: Alpha Motor Beta Motor Original Cost 37,812 48,247 Annual Maintenance 1,514 755 Life, years 10 10 Efficiency 87% 92% Taxes and Insurance 3% 3% Power cost is 2.00 per kWh. If money is worth 20%, how many hours per year would the motors have to be operated at full load for them to be equally economical?

Select a conventional ICE (Internal Combustion Engine) passenger car from the market. Convert the ICE powertrain to an electric powertrain using the structural and performance parameters of the vehicle by calculating the electric motor shaft power, torque and speed, sketching the required graphs of the vehicle performance, selecting a proper gearbox ratio, analysing the gradeability performance of the car, selecting a battery pack and define battery voltage, current and energy capacity (Give thereasons of your selection), and defining the performance and energy consumption of the car for a specific drive cycle (calculate the cost of the drive considering the price of electricity too).
