In August 2015, a Toyota Prius lists at $26,985 as its manufacturer suggested retail price. The corresponding retail price for the Nissan Leaf lists at $29,010.

The Prius has a city-highway combined efficiency of 50 miles per gallon. For the base-case analysis, lets assume a gas price at $3.00 per gallon. This will result in a mileage efficiency of 6 /mile.

The Leaf has an efficiency of 5.4 miles/kWh.[1] For base-case analysis, lets assume electricity supply at a price of 12 /kWh. This will result in a mileage efficiency of 2.2222 /mile.[2]

For simplicity of analysis, lets assume the a driver who needs to drive 12,000 miles a year or 1,000 miles a month for work, school, and other transportation needs. Lets further assume the driver faces an auto loans interest rate of 3% per year or .25% per month.

To do: We first perform a base-case analysis using the data provided or assumed so far.

Q1: Calculate the monthly cash flows for purchasing and operating the Prius for 10 years. (10%)

Q2: Calculate the monthly cash flows for purchasing and operating the Leaf for 10 years. (10%)

Q3: From the monthly cash flows in the previous two questions, derive the incremental cash flows of purchasing the more expensive Leaf over the less-expensive Prius for 10 years. (10%)

Q4: From the incremental cash flows established in Q3 above, find the following capital-budgeting measures.

[1] We obtain the 5.4 miles per kWh statistic from http://insideevs.com/long-term-nissan-leaf-mileageusage-review-once-around-the-sun/.

[2] The 2.2222 cents per mile number is consistent with Sharon Terleps article in The Wall Street Journal, August 12, 2009, where she reported the Chevrolet Volts lithium-ion battery pack can deliver a range of 40 miles before it needs recharging at 88 cents per charge. The Leaf has a range of 84 miles per full charge. We did not choose the Volt because the Volt is not an all-electric car with its fossil-fuel internal combustion engine backup propulsion.
