When fully charged, you will pay about 10.0¢ per mile for the first 16 miles you drive ($1.25 for the electricity and $.35 for the gasoline).

After the first 16 miles, the vehicle will function like a regular hybrid and consume only gasoline, costing about 17.9¢/mile.

You will spend $1.25 on electricity and $1.98 on gasoline. This calculation assumes that your vehicle is fully charged when you begin your 25 mile trip and that you do not recharge during the trip.

Miles on a tank and refueling cost for gasoline only assumes 90% of fuel in tank will be used before refueling.

Personalized estimates are currently not available for this vehicle.

This vehicle did not use any gasoline for the first 21 miles in EPA tests. However, depending on how you drive the vehicle, you may use both gasoline and electricity during the first 21 miles following a full charge.
